Australian television broadcasting commenced in 1956 in Melbourne and Sydney to coincide with the 1956 Summer Olympics. Three stations commenced operations on a ten channel spectrum arrangement: the ABC operating in the VHF low band (VHF Ch 2), and the commercial stations operating in the VHF high band (VHF Ch 7 & 9). At the outset, commercial stations were independently owned, but due to economic forces network affiliations were soon established. This pattern of television spectrum allocation was replicated in most of the state capital cities over the subsequent decade, with the exception of Hobart (one commercial service on VHF 6) and eventually Darwin (both the ABC and the commercial service were allocated in the VHF high band).

The VHF bands were more desirable because they carried longer distances. Since there were only twelve VHF channels available, there were limitations as to how closely the stations could be spaced. After the FCC's Sixth Report and Order ended the license freeze and opened the UHF band in 1952, it devised a plan for allocating VHF licenses. Under this plan, almost all of the country would be able to receive two commercial VHF channels plus one noncommercial channel.
The last British VHF TV transmitters closed down on January 3, 1985. VHF band III is now used in the UK for digital audio broadcasting, and VHF band II is used for FM radio, as it is in most of the world. Unusually, the UK has an amateur radio allocation at 4 metres, 70-70.5 MHz.

In the early days of broadcast television, there were twelve VHF channels available and 69 UHF channels (later reduced to 55 in 1983). The VHF bands were more desirable because they carried longer distances. Since there were only twelve VHF channels available, there were limitations as to how closely the stations could be spaced. After the FCC's Sixth Report and Order ended the license freeze and opened the UHF band in 1952, it devised a plan for allocating VHF licenses.
This means that at a given received power, a UHF analog signal will appear worse than VHF, often significantly. For these reasons, in order to allow UHF stations to provide the same ground coverage as VHF, ideally about , the FCC allowed UHF broadcasters to operate at much higher power levels. For analog signals in the United States, VHF signals on channels 2 to 6, the low-VHF range, were limited to 100 kW, high-VHF on channels 7 to 13 to 316 kW, and UHF to 5 MW, well over 10 times the power of the low-VHF transmitter power limit. This greatly increased the cost of transmitting in these frequencies, both in electrical cost as well as the upfront cost of the equipment needed to reach those power levels.

After World War II, frequency channels (VHF and UHF) were being assigned by FCC Engineering staff for television stations. Unfortunately, local television was non-existent in Springfield before July 1953. In October 1948 the Freeze of 1948 occurred, with channel 2 (VHF) moved from Springfield to St. Louis. Channel 8 (VHF) was eventually moved from Peoria to Moline by 1963.
There are two types of tuners in analog television, VHF and UHF tuners. The VHF tuner selects the VHF television frequency. This consists of a 4 MHz video bandwidth and a 2 MHz audio bandwidth. It then amplifies the signal and converts it to a 45.75 MHz Intermediate Frequency (IF) amplitude-modulated picture and a 41.25 MHz IF frequency-modulated audio carrier.
The analogue television transmitters (VHF and UHF) were switched off in November 2012. One tower, built to transmit the original VHF analogue television services of NBN Television on VHF Channel 3, transmits NBN and two government digital TV services.

87.5 to 88.0 MHz is considered part of the VHF TV low band. For TV, 15.241 and 15.242 deal with high VHF (channels 7 to 13), 15.242 also deals with UHF (band IV and band V).
Cable television represented a possible alternative to deployment of UHF converters as broadcasts could be frequency-shifted to VHF channels at the cable head-end instead of the final viewing location. However, most cable systems could not accommodate the full 54-890 MHz VHF/UHF frequency range and the twelve channels of VHF space were quickly exhausted on most systems. Adding any additional channels therefore needed to be done by inserting the extra signals into cable systems on nonstandard frequencies, typically either below VHF channel 7 (midband) or directly above VHF channel 13 (superband). These frequencies corresponded to non-television services (such as two-way radio) over-the-air and were therefore not on standard TV receivers.

Often, ships use separate VHF DSC and MF/HF DSC controllers. For VHF, DSC has its own dedicated receiver for monitoring Channel 70, but uses the main VHF transceiver for transmission. However, for the user, the controller is often a single unit. MF/HF DSC devices monitor multiple distress, urgency and sécurité bands in the 2, 4, 6, 8, 12 and 16 MHz bands.
Out of those, twelve did not indicate they would continue broadcasting. 133 stations planned to share, 29 were moving from UHF to VHF, and one was moving from high-VHF to low-VHF.

The area never had UHF before DTV, so most people had VHF antennas, while few people lived in apartment buildings. The higher power needed for UHF cost too much, and channel 24 had signal problems, so the station asked to move back. Of 79 stations asking for a new channel, 22 wanted to go from VHF to UHF, and 10 wanted to go from UHF to VHF.
Before the existence of cell phones, Improved Mobile Telephone Service (IMTS) was offered. As of 1983, three VHF and two UHF channels were available. Subscribers had either a VHF or UHF vehicle-mounted phone, consequently they could access only two or three channels over the entire San Jose area. On VHF, the maximum system capacity for the San Jose system was three simultaneous calls.

British television originally used VHF band I and band III. Television on VHF was in black and white with 405-line format (although there were experiments with all three colour systems-NTSC, PAL, and SECAM-adapted for the 405-line system in the late 1950s and early 60s). British colour television was broadcast on UHF (channels 21-69), beginning in the late 1960s. From then on, TV was broadcast on both VHF and UHF (VHF being a monochromatic downconversion from the 625-line colour signal), with the exception of BBC2 (which had always broadcast solely on UHF).
The VHF Data Link or VHF Digital Link (VDL) is a means of sending information between aircraft and ground stations (and in the case of VDL Mode 4, other aircraft). Aeronautical VHF data links use the band 117.975–137 MHz assigned by the International Telecommunication Union to Aeronautical mobile (R) service. There are ARINC standards for ACARS on VHF and other data links installed on approximately 14,000 aircraft and a range of ICAO standards defined by the Aeronautical Mobile Communications Panel (AMCP) in the 1990s. Mode 2 is the only VDL mode being implemented operationally to support Controller Pilot Data Link Communications (CPDLC).
To illustrate the channel crowding problem, the following cities were never allocated any VHF-TV stations at all, due to technical reasons found by the FCC: Huntsville, Alabama; Fort Wayne, Indiana; South Bend, Indiana, Lexington, Kentucky; Springfield, Massachusetts; Youngstown, Ohio; Scranton/Wilkes-Barre, Pennsylvania; and Yakima, Washington. Other cites were able to receive only one VHF broadcast station. The entire state of New Jersey would receive only one VHF broadcast station of its own (which was to ultimately become WNET 13 Newark). Similarly, Delaware also had only one VHF station. Meanwhile, UHF broadcasting until 1949 was designated as experimental.
Another design, used mainly for UHF reception, is the reflective array antenna, consisting of a vertical metal screen with multiple dipole elements mounted in front of it. The television broadcast bands are too wide in frequency to be covered by a single antenna, so either separate antennas are used for the VHF and UHF bands, or a combination (combo) VHF/UHF antenna. A VHF/UHF antenna is really two antennas feeding the same feedline mounted on the same support boom. Longer elements which pick up VHF frequencies are located at the "back" of the boom and often function as a log-periodic antenna.
KQTV began broadcasting its digital signal at 1,000 kW on UHF channel 53 in 2003. Since that allocation was among the high band UHF channels (52-69) that were removed from broadcasting use as a result of the transition, it seemed likely that KQTV would relocate its digital signal to VHF channel 2. However, low-band VHF signals are more prone to interference from atmospheric conditions than higher channel numbers. For these reasons when the station discontinued regular programming on its analog signal, over VHF channel 2, on February 18, 2009, the station's digital signal moved to VHF channel 7.
The C-38 also has controls for the R-4A homing receiver. A common AN/ARC-5 transmitter control box C-30A/ARC-5 has controls for selecting the MF/HF transmitter or the VHF transmitter, and a switch to select the channel for both the VHF transmitter and receiver. Mode controls are normally set for voice and covered. The typical AN/ARC-5 three- receiver, two-transmitter installation reflects system capabilities that are quite sophisticated compared to the earlier systems, allowing VHF homing, four channel VHF-AM communications, and one channel MF/HF-AM communications.
KCTS-TV shut down its analog signal, over VHF channel 9, on June 12, 2009, as part of the federally mandated transition from analog to digital television. The station's digital signal relocated from its pre-transition UHF channel 41 to VHF channel 9.
Channel 16 VHF (156.8 MHz) is a marine VHF radio frequency designated as an international distress frequency. Primarily intended for distress, urgency and safety priority calls, the frequency may also carry routine calls used to establish communication before switching to another working channel.

At 1607 the pilot decided to head directly for the VHF omnirange at Sherbrooke, Quebec.
To allocate four to as many as seven VHF channels to each of the largest cities would mean forcing the smaller, intervening cities completely onto UHF channels, while an allocation scheme that sought to assign one or two VHF channels in each smaller city would force VHF and UHF stations to compete in most markets. The largest cities with the most sets in use benefitted most from VHF allocations. For example, New York City, Washington- Baltimore, Los Angeles, and San Francisco received seven VHF stations apiece, and Chicago was allocated five, with the other two of those channels going to Milwaukee, Wisconsin and Rockford, Illinois. FCC rules published on April 11, 1952, defined the final modern-day UHF allocation of 70 channels, 14 through 83, with 6 MHz separation.
The Sixth Report and Order also provided for the "intermixture" of VHF and UHF channels in most markets; UHF transmitters in the 1950s were not yet powerful enough, nor receivers sensitive enough (if they included UHF tuners at all - they were not formally required until the 1960s All-Channel Receiver Act), to make UHF viable against entrenched VHF stations. In markets where there were no VHF stations and UHF was the only TV service available, UHF survived. In other markets, which were too small to financially support a television station, too close to VHF outlets in nearby cities, or where UHF was forced to compete with more than one well-established VHF station, UHF had little chance for success. Denver had been the largest U.S. city without a TV station by 1952.
Many businesses and industries throughout the world use LMR as their primary means of communication, especially from a fixed location to mobile users (i.e. from a base site to a fleet of mobiles). Commercial LMR Radios are typically available in the VHF and UHF frequency bands. 30−50 MHz (sometimes called "Low VHF Band" or "Low Band"), 150−172 MHz (sometimes called "High VHF Band" or "High Band"), 450−470 MHz "UHF".
KOTI shut down its analog signal, over VHF channel 2, on February 17, 2009, the original target date in which full-power television stations in the United States were to transition from analog to digital broadcasts under federal mandate (which was later pushed back to June 12, 2009). The station's digital signal remained on its pre-transition VHF channel 13, using PSIP to display the station's virtual channel as its former VHF analog channel 2.
WYES-TV shut down its analog signal, over VHF channel 12, at 7 a.m. on June 12, 2009, the official date in which full-power television stations in the United States transitioned from analog to digital broadcasts under federal mandate. The station's digital signal continued to broadcasts on its pre-transition VHF channel 11. Through the use of PSIP, digital television receivers display the station's virtual channel as its former VHF analog channel 12.
This modern DTV antenna uses a Yagi for UHF reception placed in front of a log-periodic for VHF-high. Although the UHF band has five times as many channels as VHF, the antenna needed to receive them is much smaller in both length and width. An older design that also received VHF-low would have many more elements extending to the right. The most common type of antennas rely on the concept of resonance.
In January 1987, Spacemen 3 commenced work on their second album, The Perfect Prescription. This was recorded at Paul Atkins' VHF Studios, near Rugby. VHF had been recommended to the band by in-house sound engineer Graham Walker with whom they had worked previously when recording their first demo tape. The first set of demo recordings they made at VHF Studios relating to the new album were dubbed the 'Out Of It Sessions'.
Two frequency bands available: VHF-FM (142–143 MHz VHF CB) and UHF-FM (476–477 MHz UHF CB). Indonesia allows 40 channels from 476.425 MHz to 477.400 MHz at 25 kHz channel spacing. It is the same channel plan as the original 40 channel Australia/New Zealand UHF CB allocation. Indonesia also has a 60-channel VHF- FM service available from 142.050 MHz to 143.525 MHz (channels spaced every 25 kHz).
The station was built in 1957 by the BBC to bring BBC Television to North East Scotland for the first time. The 405-line monochrome transmissions were on channel 2, Band I VHF. When colour UHF television began in 1970, the site was chosen over the nearby IBA owned station at Mounteagle to carry these broadcasts. Both the UHF and VHF services continued in tandem until 1985, when VHF television was discontinued in the UK.

KACV began transmitting a digital television signal on VHF channel 8 in 2002. The station shut down its analog signal, over VHF channel 2, on February 17, 2009, the original target date in which full-power television stations in the United States were to transition from analog to digital broadcasts under federal mandate (which Congress later pushed back to June 12, 2009 by resolution three weeks before all full-power stations were scheduled to transition). The station's digital signal remained on its pre- transition VHF channel 8, using PSIP to display KACV's virtual channel as its pre-transition VHF analog channel 2 on digital television receivers.
One notable exception to historical patterns favoring VHF broadcasters has existed in television markets that could not qualify for their own VHF stations because they were sandwiched between the outer fringes of VHF stations in two or more larger markets. Such cities received only UHF licenses. With all stations (including network affiliates) on UHF, all-channel receivers and antennas became commonplace locally and UHF stations signing on as early as 1953 were often able to obtain the programming and audience needed to remain viable into the modern era.WSJV 28 South Bend, Indiana history indicates station founded 1954, still extant as no VHF channels available due to proximity to Chicago.
In many cases, a receiver will not automatically add the new mapping at all if an old one exists. Completely re-scanning will normally solve this, but may not pick-up stations that are weak or temporarily off-air during the scan, causing the need to manually enter them (if this is even possible with the given receiver). Where stations are moving to a different frequency band (such as UHF to VHF), this will affect antenna selection. Many antennas marketed for HDTV use are UHF-only or perform poorly on VHF, while many 82-channel VHF/UHF antennas are a compromise design strongly favoring VHF channels.
The AN/ARC-5 certainly represents the climax development of the pre-war MF/HF command set. But its VHF AN/ARC-5 set and the AN/ARR-2 homing adapter presaged a move toward higher frequencies. During World War II, the Navy began a slow movement toward VHF-AM for command functions in theaters where it made sense, beginning with the Western Electric WE-233A commercial airline set which was later re-designated the AN/ARC-4. By 1943 they began deploying their own AN/ARC-1 ten-channel VHF-AM set in increasing numbers, but hedged their bets with the AN/ARC-5 VHF sets in certain aircraft.
The three original VHF radio transmitters were upgraded to stereo in late Spring 1983. The 405-line VHF television service closed across the UK in 1985, but Machynlleth's 405 line services closed a year early - in January 1984. Machynlleth currently broadcasts digital television and analogue FM radio.

Each AIS transceiver consists of one VHF transmitter, two VHF TDMA receivers, one VHF Digital Selective Calling (DSC) receiver, and links to shipboard display and sensor systems via standard marine electronic communications (such as NMEA 0183, also known as IEC 61162). Timing is vital to the proper synchronization and slot mapping (transmission scheduling) for a Class A unit. Therefore, every unit is required to have an internal time base, synchronized to a global navigation satellite system (e.g. GPS) receiver.
WOWK-TV discontinued regular programming on its analog signal, over VHF channel 13, in early 2009. The station's digital signal relocated from its pre-transition UHF channel 47 to VHF channel 13.CDBS Print On January 25, 2009, an ice storm damaged the primary analog VHF channel 13 transmitter. Rather than repair it for two more months of service, the station shut down its analog transmission early and brought its digital channel 13 transmitter on-line.
In order to identify the VHF transmitter as quickly as possible in countries or locations where natural elevations were lacking, and a VHF agent could only be heard within a short distance, it became necessary to use captive balloons. In the Netherlands, e.g. where it was necessary to find up to 30 operational sites to be sure of picking up the agent with VHF, according to methodology, one single captive balloon was all that was needed to achieve this.
Triodes were used in VHF amplifiers in 'grounded- grid' configuration, a circuit arrangement which prevents Miller feedback.

Below the Citizen's Band, the U.S. military has the frequencies from 26.480 to 26.960 MHz. The Civil Air Patrol has 26.620 MHz, though it now uses mostly VHF frequencies. In the 1950s through the 1970s CAP volunteers with crystal-controlled CBs would put this frequency in their radios. Currently VHF military frequencies are more often used (the CAP is part of the US Air Force), as among other reasons, VHF radios are easier to acquire through military logistics than CB radios.
Like the QRA system before it, Maidenhead locators were enthusiastically adopted by radio amateurs beyond contesting, and it is now in widespread use. Maidenhead locators are still used as part of the formulas for scoring in many VHF amateur radio contests and as the basis of earning awards like the American Radio Relay League's VHF/UHF Century Club, URE TTLOC, etc. operating award. In IARU Region 1 rules, VHF distance calculations are carried out between Maidenhead subsquare centres assuming a spherical Earth.
Other contests may permit activity on all bands but restrict stations to making only one contact with each other station, regardless of band, or may limit multipliers to once per contest instead of once per band.

WUFT first signed on the air with instructional programming on November 17, 1958, becoming the third educational television station in Florida. The station was a major beneficiary of a quirk in the FCC's plan for allocating stations. In the early days of broadcast television, there were 12 VHF channels available and 69 UHF channels (later reduced to 55 in 1983). The VHF bands were more desirable because they carried longer distances. Since there were only 12 VHF channels available, there were limitations as to how closely the stations could be spaced. After the FCC's Sixth Report and Order ended the license freeze and opened the UHF band in 1952, it devised a plan for allocating VHF licenses.
Air Board documentation indicates that the Fighter Sector VHF/RT system (Very High Frequency Radio Transmission System) was to comprise: 3 VHF/DF (Direction Finder) fixer stations, 1 VHF/DF homing station, 1 remote (local) transmitting station, 1 remote (local) receiving station and 2 relay stations (each consisting of a receiver and transmitter). In the case of the Sydney ADHQ relay stations were considered unnecessary by Defence authorities as it was anticipated that the height of the sites selected for the new VHF transmitter and receiver stations would ensure satisfactory communications. As it turned out, the new transmitting and receiver stations were never built and the Sydney ADHQ relied on the existing receiving station at Picnic Point, Revesby and the existing transmitting station at Johnston Street, Bass Hill. According to surviving documents radar stations at Robertson, Wentworth and Somersby were to acted as VHF/DF Fixer stations for the ADHQ.
Band III is the name of the range of radio frequencies within the very high frequency (VHF) part of the electromagnetic spectrum from 174 to 240 megahertz (MHz). It is primarily used for radio and television broadcasting. It is also called high-band VHF, in contrast to Bands I and II.

It was one of several television stations across the United States that took part in a 1956 lawsuit to prevent VHF stations from being added in their markets, on the grounds that UHF stations in that era typically suffered financially or even went out of business entirely if they had any VHF competition."Court Is Asked to Keep TV Stations Off Air". Elwood Call-Leader, April 19, 1956. The lawsuit was unsuccessful, however, and KRIS and KZTV were both on air as VHF stations by fall 1956.

In October 14, 1954, the Hanoi Radio commenced broadcasting for the first time. On January 6, 1978, Hanoi People's Committee decided the 41/QDTC to Hanoi Radio open the Television service. The television service launched on 1 January 1979 at 2PM (GMT+7). Originally, it is the 45 minutes programmes block on VTV1 (channel 6 VHF). It later became sole television channel, broadcast on channel 6, VHF, replaced VTV3 (at that time VTV3 was aired on channel 6 VHF, later it moved to channel 22 UHF).
Class B transceivers are smaller, simpler and lower cost than Class A transceivers. Each consists of one VHF transmitter, two VHF Carrier Sense Time Division Multiple Access (CSTDMA) receivers, both alternating as the VHF Digital Selective Calling (DSC) receiver, and a GPS active antenna. Although the data output format supports heading information, in general units are not interfaced to a compass, so this data is seldom transmitted. Output is the standard AIS data stream at 38.400 kbit/s, as RS232 and/or NMEA formats.

After that time, no more stations could join, but bids from those who did would not be final until March 29, 2016. The FCC released opening bid prices on October 16. These included three categories: stations giving up or sharing channels (which would mean the offering the full price), stations moving from UHF to high VHF (less than full price), and stations moving from high VHF to low VHF (lower than full price but not the lowest). Other factors were the number of people served and interference.
TV and FM (frequency modulated ) radio transmitter stations as well as transposer stations are almost always built on top of hills. A single station may have many transmitters both for TV and FM. In rare cases, each transmitter has an antenna system. But in stations where many transmitters are used, this is not always possible, so the outputs of transmitters transmitting in the same frequency band are combined by a diplexer and applied to a single antenna system. (i.e. VHF 1, VHF 2, VHF 3, UHF).

The longer wavelength of VHF means it can transmit further under normal conditions. For most applications, lower radio frequencies are better for longer range and through vegetation. A broadcasting TV station illustrates this. A typical VHF TV station operates at about 100,000 watts and has a coverage radius range of about 60 miles.

Other complementary strategies for device scaling include channel strain engineering, silicon-on-insulator-based technologies, and high-κ/metal gate materials. Dual-gate MOSFETs are commonly used in very high frequency (VHF) mixers and in sensitive VHF front-end amplifiers. They are available from manufacturers such as Motorola, NXP Semiconductors, and Hitachi.
This included the installation of radio stations in the jungle as well as very high frequency (VHF) radiotelephony over the normal state network.

According to KHSL's engineering department, KHSL chose not return to VHF channel 12 as the digital transmission has much poorer results than UHF channels. There was still a substantial loss in over-the-air (OTA) coverage. There has been criticized because a VHF signal better covers the terrain of the rural, mountainous viewing area in local communities and could have actually gained coverage if the digital transmitter used the analog tower. However, results by most stations in the U.S. show a loss of coverage with a VHF signal, but the Chico–Redding area is unique in the fact that the valley is suited better for UHF (VHF is notorious for impulse noise) while the foothills and mountains are better suited for VHF (UHF does not travel the natural curve of the Earth well); but KHSL had to take a loss of approximately 50,000 potential viewers since it cannot satisfy both types of terrain at the same time, less than it would have on VHF 12 but still much worse than the other stations in the area which saw little or no loss in coverage.

The station was a major beneficiary of a quirk in the Federal Communications Commission (FCC)'s plan for allocating stations. In the early days of broadcast television, there were twelve VHF channels available and 69 UHF channels (later reduced to 55 in 1983). The VHF bands were more desirable because they carried longer distances.
The network wanted to see if a UHF station could effectively compete against VHF stations, and attempted to make the stations more competitive by investing in significant equipment upgrades. However, WBUF consistently ranked behind its VHF competitors, WGR-TV (channel 2, now WGRZ) and WBEN-TV (channel 4, now WIVB-TV). Similarly, WNBC consistently rated behind VHF competitor WNHC-TV (channel 8, now WTNH); WNBC faced an additional problem as its signal was not strong enough to cover New Haven and western Connecticut (nearly all of Connecticut is part of the Hartford-New Haven market).
From 1945 to 1948 TV stations in the U.S. shared Channel 1 and other channels with fixed and mobile services. The FCC decided in 1948 that a primary (non-shared) allocation of the VHF radio spectrum was needed for television broadcasting. Except for selected VHF frequencies in Alaska and Hawaii (and some overseas territories) the FCC-administered VHF band is primarily allocated for television broadcasting to this day. The FCC in May 1948 formally changed the rules on TV band allocations based on propagation knowledge gained during the era of shared-user allocations.

The first Canadian television network was publicly owned Radio-Canada, the Canadian Broadcasting Corporation. Its stations, as well as that of the first private networks (CTV and TVA, created in 1961), are primarily VHF. More recent third-network operators initially signing-on in the 1970s or 1980s were often relegated to UHF, or (if they were to attempt to deploy on VHF) to reduced power or stations in outlying areas. Canada's VHF spectrum was already crowded with both domestic broadcasts and numerous American TV stations along the border.
In Japan, an is one of a loosely knit group of free commercial terrestrial television stations that is not a member of the major national networks keyed in Tokyo and Osaka. Japan's original broadcasters were VHF. Although some experimental broadcasts were made as early as 1939, NHK (founded in 1926 as a radio network modeled on the BBC) began regular VHF television broadcasting in 1953. Its two terrestrial television services (NHK General TV and NHK Educational TV) appear on VHF 1 and 3, respectively, in the Tokyo region.
KNIK-LP, VHF analog channel 6 (VHF digital channel 3), is a low-powered television station licensed to Anchorage, Alaska, United States. The station is one of very few low-power television stations that operate predominantly as a radio station by way of the fact that many FM radio receivers can tune in a VHF channel 6 television audio carrier at 87.75 MHz. This technique is made more potent due to a formerly unforeseen interpretation of deregulatory language in FCC low-power television station regulations: > Sec. 73.653 Operation of TV aural and visual transmitters.

Procurable only as bootleg, this work shows the transition in Spacemen 3's musical style that was occurring around winter 1986/87. VHF Studios' 8-track facilities needed updating though, and a deal was agreed that Spacemen 3 would receive a large amount of studio time in return for financing new 16-track recording and mixing equipment at VHF, at a cost of around £3,000. Spacemen 3 would spend over eight months at VHF Studios. Importantly, this allowed them generous time to experiment, and develop and refine their sound and material in a studio setting, assisted by Graham Walker.
The U.S. Weather Bureau first began broadcasting marine weather information in Chicago and New York City on two VHF radio stations in 1960 as an experiment. Proving to be successful, the broadcasts expanded to serve the general public in coastal regions in the 1960s and early 1970s. By early 1970, ESSA listed 20 U.S. cities using 162.550 MHz and one using 163.275 "ESSA VHF Radio Weather." Later, the U.S. Weather Bureau adopted its current name, National Weather Service (NWS), and was operating 29 VHF-FM weather-radio transmitters under the National Oceanic and Atmospheric Administration (NOAA) which replaced ESSA in 1970.

Mobile coverage extends to nearly all inhabited areas in Greenland, but there are some remote areas that do not have mobile coverage. In Greenland, VHF radio-telephone is also used. Users make calls over a radio instead of a phone. Outside of Greenland, VHF phones are only used on ships, but in Greenland they can also used as regular phones.
VHF is reserved for TRT 1 and UHF for the others. The private broadcasters use UHF band. According to the regulation a channel difference of at least 3 channels (21 MHz in VHF and 24 MHz in UHF) is required in each region. Thus in certain high population-density areas some broadcasters face the problem of shortage in channel availability.
PAL/SECAM analogue SDTV broadcasts use 6-, 7- (VHF), or 8 MHz (UHF). The 819-line (system E) used 14 MHz wide VHF channels. For HD-MAC, the transmission medium must guarantee a baseband bandwidth of at least 11.14 MHz.ETSI specification of the D2-HDMAC/Packet system (ETS 300 352), section 4.1 This translates to a 12 MHz channel spacing in cable networks.

Call boxes may be wired or wireless. Wireless systems use radio frequencies in the VHF or UHF business band radio spectrum. Many callboxes can be programmed to be compatible with virtually any brand of VHF or UHF business band portable or fixed-base radio. Many in the United States require an FCC license, but some are certified for use on special FCC license-free business frequencies.
In comparison, VHF noise is largely unpredictable, consisting of periods of little noise followed by periods of almost complete signal loss. Forward error correction cannot easily address this situation. For this reason, DTV broadcasting was initially going to take place entirely on UHF. In the US, the FCC initially wanted to move all stations to UHF, auctioning off the VHF frequencies for cell phone use.

The development of FM broadcasting improved fidelity by using a greater bandwidth which was available in the VHF range, and where atmospheric noise was absent. FM also has an inherent ability to reject noise, which is mostly amplitude modulated. Valve technology suffers high-frequency limitations due to cathode-anode transit time. However, tetrodes are successfully used into the VHF range and triodes into the low GHz range.

In the 1970s and 1980s, the Scandinavian Twin Auroral Radar Experiment (STARE) very high frequency (VHF) coherent scatter radars were used to study field aligned E region ionospheric irregularities. Using two radars with overlapping fields of view, it was possible to determine the 2D velocity vector of E region ionospheric plasma flow. However, irregularities were only observed when the radar wavevector was perpendicular to the magnetic field in the scattering region. This meant that there was a problem with operating at VHF since VHF frequencies don't allow for very much refraction of the transmitted radar wave vector; thus, the perpendicularity requirement could not be easily met at high latitudes.
WRCB shut down its analog signal, over VHF channel 3, on June 12, 2009, the official date in which full-power television stations in the United States transitioned from analog to digital broadcasts under federal mandate.

UHF and VHF SAR have begun limited operations on Army RC-12 aircraft and may be implemented on the Global Hawk. DARPA's WATCH-IT program developed robust low false alarm density change detection software to detect vehicles and smaller targets under foliage, under camouflage and in urban clutter, and developed tomographic (3D) imaging to detect and identify targets that have not relocated. VHF/UHF SAR for building penetration, urban mapping and performing change detection of objects inside buildings. Terrain characterization technologies were also developed, including the abilities to rapidly generate bald-earth terrain height estimates and to classify terrain features from multipass VHF/UHF SAR imagery.
Low channels travel further than high ones at the same power, but UHF does not suffer from as much electromagnetic interference and background "noise" as VHF, making it much more desirable for TV. Despite this, in the U.S., the Federal Communications Commission (FCC) is taking another large portion of this band (channels 52 to 69) away, in contrast to the rest of the world, which has been taking VHF instead. This means that some stations left on VHF are harder to receive after the analog shutdown. Since at least 1974, there are no stations on channel 37 in North America for radio astronomy purposes.
This means that the band can be "compressed" into fewer channels, while still allowing for more transmissions. In the United States, the abandoned television frequencies are primarily in the upper UHF "700-megahertz" band, covering TV channels 52 to 69 (698 to 806 MHz). U.S. television and its white spaces will continue to exist in UHF frequencies, as well as VHF frequencies for which mobile users and white-space devices require larger antennas. In the rest of the world, the abandoned television channels are VHF, and the resulting large VHF white spaces are being reallocated for the worldwide (except the U.S.) digital radio standard DAB and DAB+, and DMB.
AMV, meanwhile expanded into the rest of Victoria as the state's Seven Network affiliate, in competition with Vic TV and Southern Cross. RVN's callsign ceased to exist in 1991, when the Wagga and Orange licenses were merged to become only CBN. At the same time, AMV moved from VHF channel 4 to VHF channel 11, in order to allow FM stations to be established without interference from existing television stations (using VHF channels 3, 4, 5 and 5A). In preparation for aggregation of the Victorian market - (excluding Mildura) - in early 1992, a studio facility and playout centre was constructed in the Ballarat suburb of Mitchell Park.
VHF radar systems have wavelengths comparable to aircraft feature sizes and should exhibit scattering in the resonance region rather than the optical region, allowing most stealth aircraft to be detected. This has prompted Nizhny Novgorod Research Institute of Radio Engineering (NNIIRT) to develop VHF AESAs such as the NEBO SVU, which is capable of performing target acquisition for Surface-to-air missile batteries. Despite the advantages offered by VHF radar, their longer wavelengths result in poor resolution compared to comparably sized X band radar array. As a result, these systems must be very large before they can have the resolution for an engagement radar.

This reflective array television antenna consists of eight "bowtie" dipole driven elements mounted in front of a wire screen reflector. The X-shaped dipoles give it a wide bandwidth to cover both the VHF (174-216 MHz) and UHF (470-700 MHz) bands. It has a gain of 5 dB VHF and 12 dB UHF and an 18 dB front-to-back ratio. The example shown is horizontally polarised.
In September 1965, the station was acquired by Tribune Broadcasting – then known as WGN Continental Broadcasting."WGN Inc. buying VHF in Denver." Broadcasting, Sept. 6, 1965, pg. 57.

Depending on types of broadcast, free-to-air television networks and stations can be received by either using a UHF/VHF antenna or free-to-air satellite dish.
However, after phase one of the FCC repack, channel 23 will go to WNWO-TV. Subsequently, the station has filed to move operations to VHF analog channel 6.
Under this plan, almost all of the country would be able to receive two commercial VHF channels plus one noncommercial channel. Most of the rest of the country ("1/2") would be able to receive a third VHF channel. Other areas would be designated as "UHF islands" since they were too close to larger cities for VHF service. The "2" networks became CBS and NBC, "+1" represented non-commercial educational stations, and "1/2" became ABC (which was the weakest network usually winding up with the UHF allocation where no VHF was available). However, Alexandria was sandwiched between Shreveport (channels 3, 6, and 12) and Monroe–El Dorado (channels 8, 10, and 13) to the north, Lafayette (channels 3 and 10), Lake Charles (channel 7), and Baton Rouge (channels 2 and 9) to the south, and Northwestern Mississippi (channel 6), New Orleans (channels 4, 6, 8, 11, and 12), and Jackson (channels 3 and 12) to the east.
However the 1970s saw a large increase in UHF TV viewing while VHF took a significant decline: The appeal of colour, which was never introduced to VHF (despite preliminary plans to do so in the late 1950s and early 1960s) and the fall in television prices saw most households use a UHF set by the end of that decade. With the second and last VHF television service having launched in 1955, VHF TV was finally decommissioned for good in 1985 with no plans for it to return to use. The launch of Channel 5 in 1997 added a fifth national television network to UHF, requiring deviation from the original frequency allocation plan of the early 1960s and the allocation of UHF frequencies previously not used for television (such as UK Channels 35 and 37, previously reserved for RF modulators in devices such as domestic videocassette recorders, requiring an expensive VCR re-tuning programme funded by the new network).
WJBK began airing its digital high-definition feed, WJBK-DT, on UHF channel 58 starting on October 1, 1998. The station shut down its analog signal, over VHF channel 2, on June 12, 2009, the official date in which full- power television stations in the United States transitioned from analog to digital broadcasts under federal mandate. The station's digital signal remained on its pre-transition VHF channel 7 (which was formerly occupied by WXYZ-TV's analog signal, and was assigned to WJBK for its post-transition digital signal on May 7, 2007). Through the use of PSIP, digital television receivers continues to display the station's virtual channel as its former VHF analog channel 2.1.
Other areas would be designated as "UHF islands" since they were too close to larger cities for VHF service. The "2" networks became CBS and NBC, "+1" represented non-commercial educational stations, and "1/2" became ABC (which was the weakest network usually winding up with the UHF allocation where no VHF was available). However, what would become of the Gainesville market is sandwiched between Jacksonville (channels 4, 7, and 12) to the northeast, Tallahassee (channels 6 and 11) to the northwest, and Orlando (channels 2, 6, and 9) and Tampa Bay (channels 3, 8, 10, and 13) to the south. This created a large "doughnut" in north-central Florida where there could only be one VHF license.
Nevertheless, moving from a 100 kW low-VHF analog signal to a 1 MW UHF signal is still a considerable change, which some broadcasters estimated could cost up to $4 million per station (although most estimates were much lower, on the order of $400,000). For this reason, channels in the high-VHF region were kept for television use. The power of the stations on these channels was also reduced, to 160 kW, about one-third of the earlier limit. Stations making the transition generally acquired a second channel allocation in the upper UHF region to test their new equipment, and then moved into the low-UHF or high-VHF once the conversion period was over.
Many of these services require non-removable antennas or place restrictions on antenna size, height or gain. The high-VHF band (137–174 MHz) and UHF bands (325, 900 MHz) are the most popular aside from the 25–28 MHz "HF CB" bands. There are notable exceptions to this, including the 78 MHz and 245 MHz Thai "CB 78" and "CB 245" VHF-FM bands, the 68–71 MHz Finnish band, the 30–31 MHz Swedish "Hunting Radio" band, and the 43 MHz Italian "VHF CB" bands. The lower frequency allocations (especially the 30/31 and 43 MHz bands) often exhibit propagation and communication range characteristics similar to 27 MHz CB radio.
This sale allowed the merger between Sunrise and LIN TV to be completed the following month. LIN TV continued to operate WNAC under the same LMA it inherited from Sunrise. WPRI- TV received Federal Communications Commission (FCC) consent to discontinue regular programming on its analog signal, over VHF channel 12, on February 17, 2009, the original date when full-power television stations in the United States were to transition from analog to digital broadcasts under federal mandate (which was later pushed back to June 12, 2009). The station's digital signal remained on its pre-transition VHF channel 13, using PSIP to display the station's virtual channel as its former VHF analog channel 12.
KOCO-TV began transmitting a digital television signal on VHF channel 7 on November 1, 2002. The station discontinued regular programming on its analog signal, over VHF channel 5, on June 12, 2009, as part of the federally mandated transitioned from analog to digital television. The station's digital signal remained on its pre-transition VHF channel 7, using PSIP to display KOCO-TV's virtual channel as 5 (corresponding to its analog channel) on digital television receivers. After the switchover, the marginal reductions to the broadcast radius of KOCO's digital signal created some reception gaps in parts of southern and north-central Oklahoma that previously, at best, received Grade B coverage from its analog signal.
KOTA-TV, virtual channel 3 (VHF digital channel 7), is an ABC-affiliated television station licensed to Rapid City, South Dakota, United States.

VHF signals will be seen by antennas in the valley, whereas UHF bends about as much, and far less signal will be received. The same effect also makes UHF signals more difficult to receive around obstructions. VHF will quickly diffract around trees and poles and the received energy immediately downstream will be about 40% of the original signal. In comparison, UHF blockage by the same obstruction will result on the order of 10% being received.
Opened in the early 1970's, the transmitter was originally a VHF television transmitter carrying RTÉ One (Channel D 175.25 MHz) and later RTÉ Two (Channel F 191.25 MHz). These ceased transmission on VHF in 1999, after UHF transmissions from RTÉ1 and 2 began from the transmitter in 1998. The first UHF transmissions were from TG4 in 1996 with RTÉ1 and 2 migrating to UHF in the years following. FM radio transmissions began in 1992.
Okabe developed an experimental apparatus using a VHF transmitter and receiver with Yagi-Uda antennas separated some distance. In 1936, he successfully detected a passing aircraft by the Doppler- interference method; this was the first recorded demonstration in Japan of aircraft detection by radio. With this success, Okabe's research interest switched from magnetrons to VHF equipment for target detection.Nakajima, S.; “Japanese radar development prior to 1945,” IEEE Antennas and Propagation Magazine, vol.

There was VHF radio direction-finding equipment for locating vessels in trouble. The lifeboat also carried the latest DSC digital radio equipment for the vital radio communication used in search and rescue missions. The lifeboat was equipped with three VHF radios one of which was portable, together with an MF `long range`set. On the deck were powerful searchlights, and the lifeboat was also later equipped with image-intensifying night sight equipment.
Founded in 1947, NNIIRT is based in the city of Nizhny Novgorod. Beginning in 1975, NNIIRT developed the first VHF 3D radar capable of measuring height, range, and azimuth to a target. This effort produced the 55Zh6 'Nebo' VHF surveillance radar, which passed acceptance trials in 1982. In the post–Cold War era, NNIIRT developed the 55Zh6 Nebo U 'Tall Rack' radar, which has been integrated with the SA-21 anti-aircraft weapons system.
Such stations can keep the same channel number, however, because of ATSC virtual channels. Unfortunately, the higher frequencies are challenged in areas where signals must travel great distances or encounter significant terrestrial obstacles. Most stations in the low-VHF (channels 2–6) did not return to these frequencies after the transition. About 40 stations remained in the low-VHF after the transition, with the majority in smaller markets (with a few notable exceptions).
If two or more antenna systems have to be used, higher frequency antennas are mounted higher on the antenna mast. (The sequence of antenna systems on a typical TV-FM station may be from bottom to top; VHF-2, VHF-3 and UHF.) Microwave stations are also high altitude stations. Although high altitude is desirable also in GSM, the operators may use low power intracity stations for areas of high population density.

The effect is more noticeable on UHF than VHF signals as VHF signals tend to be more robust. In the early 1970s some Japanese set manufacturers developed decoding systems to avoid paying royalties to Telefunken. The Telefunken licence covered any decoding method that relied on the alternating subcarrier phase to reduce phase errors. This included very basic PAL decoders that relied on the human eye to average out the odd/even line phase errors.
CKVR shut down its analogue signal, over VHF channel 3, on August 31, 2011, the official date in which Canadian television stations in CRTC-designated mandatory markets transitioned from analogue to digital broadcasts.

VHF coverage, however, is normally limited to line-of-sight range. Shannon Aeradio, callsign "Shanwick Radio", uses over twenty HF channels and two VHF channels. At peak times it can communicate with in excess of 1,600 aircraft during a 24-hour period. Shanwick Radio maintain HF communications with all flights within the Shanwick Oceanic Control Area and are responsible for issuing voice clearances to those flights unable to contact Shanwick Oceanic directly.
The original construction permit for KCHF was granted on January 19, 1983. The station signed on in January 1984 and was granted a license to cover on June 29, 1984. It claims to be the first VHF Christian television station in the United States. During the analog era, KCHF was one of a few Christian television stations in the United States to operate on the VHF band (KJNP-TV in Fairbanks, Alaska is another example).
Bands of frequencies, especially in the VHF and UHF parts of the spectrum, are allocated for communication between fixed base stations and land mobile vehicle-mounted or portable transceivers. In the United States these services are informally known as business band radio. See also Professional mobile radio. Police radio and other public safety services such as fire departments and ambulances are generally found in the VHF and UHF parts of the spectrum.

The station's digital signal relocated from its pre-transition UHF channel 53, which was among the high band UHF channels (52-69) that were removed from broadcasting use as a result of the transition, to its analog-era VHF channel 13 for post- transition operations.
All contests use one or more amateur radio bands on which competing stations may make two-way contacts. HF contests use one or more of the 160 meter, 80 Meter, 40 Meter, 20 Meter, 15 Meter, and 10 Meter bands. VHF contests use all the amateur radio bands above 50 MHz. Some contests permit activity on all HF or all VHF bands, and may offer points for contacts and multipliers on each band.
There was VHF radio direction-finding equipment for locating vessels in trouble. The lifeboat also carried the latest DSC digital radio equipment for the vital radio communication used in search and rescue missions. The lifeboat was equipped with three VHF radios, one of which was portable, together with an MF `long range`set. On the deck were powerful searchlights, and the lifeboat was also later equipped with image-intensifying night sight equipment.
WTMJ-TV shut down its analog signal, over VHF channel 4, at noon on June 12, 2009, the official date in which full-power television stations in the United States transitioned from analog to digital broadcasts under federal mandate. The station's digital signal continued to broadcasts on its pre-transition UHF channel 28. Through the use of PSIP, digital television receivers display the station's virtual channel as its former VHF analog channel 4.
There are currently no VHF Band III digital radio stations in Canada as, unlike in much of Europe, these frequencies are among the most popular for use by television stations.
Vessels requesting passage through the swing span contact the bridge tender on marine VHF radio, whereby the tender walks the bridge to a control booth situated on the swing span.

On August 31, 2011, when Canadian television stations in CRTC-designated mandatory markets transitioned from analogue to digital broadcasts, the station's digital signal relocated from channel 47 to VHF channel 13.
The availability of FM stereo, a quieter VHF broadcast band, and better fidelity led to the specialization of FM broadcasting in music, tending to leave AM broadcasting with spoken-word material.
The switch to VHF 13 happened at the start of 1989 and, in 1990, it was sold to Vittorio de Ferrari. During this transitory phase, it was known as Canal 13.
Namely, in Kramatorsk — 103, 2 MHz, Krasnoarmiysk — 99,6 MHz, Volnovakha — 103, 8 MHz and 66,05 VHF, Starobilsk — 90.2 MHz, Bilovodsk — 92.6 MHz, Bilolutsk — 100.0 MHz, Zorynivka — 103.7 MHz, Shyroke —101.8 MHz.

The WNAO radio-TV studio on Western Boulevard in Raleigh, as seen in a 1950s postcard While WNAO-TV went on air, the two VHF channels for Raleigh and Durham, channels 5 and 11, remained in comparative hearing. The arrival of VHF television in the Triangle, which would begin with the September 2, 1954, launch of WTVD, created increasing concern at Sir Walter. In July 1954, Sir Walter petitioned the FCC to change channels 5 and 11 to noncommercial assignments and substitute UHF channels 22 and 40 in their place. Radio station WPTF, which was one of two applicants for channel 5 at Raleigh, rebutted, noting that Sir Walter did not contest the original assignment of the VHF channels to the Raleigh-Durham area.
The Blaenplwyf transmitting station (sometimes written "Blaen Plwyf" or "Blaen-Plwyf") is a broadcasting and telecommunications facility located near the village of Blaenplwyf about to the south west of the town of Aberystwyth, in Ceredigion, Wales (). It was originally built by the BBC, entering service in October 1956 acting as a main transmitter for BBC Band II VHF FM radio. It had been planned that the BBC's 405-line VHF television service would commence on the same date, but delays at Rowridge caused the official switch-on to happen six months later on 29 April 1957. Blaenplwyf was considered a main transmitter for VHF television (despite radiating only 3 kW ERP) as it was fed from a microwave link from Mynydd Pencarreg just south of Lampeter.
In the United States, any person can legally purchase a Marine VHF radio and use it to communicate without requiring any special license as long as they abide by certain rules, but in a great many other countries a license is required to transmit on Marine VHF frequencies. In the United Kingdom and Ireland and some other European countries Short Range Certificate is the minimum requirement to use a marine VHF radio. This is usually obtained after completing a course of around two days and passing an exam. This is intended for those operating on lakes and in coastal areas whereas a Long Range Certificate is usually recommended for those operating further out as it also covers HF and MF radios as well as INMARSAT systems.
Other areas would be designated as "UHF islands" since they were too close to larger cities for VHF service. The "2" networks became CBS and NBC, "+1" represented non-commercial educational stations, and "1/2" became ABC (which was the weakest network usually winding up with the UHF allocation where no VHF was available). However, Albany is sandwiched between Dothan (channels 2 and 4) to the west, Columbus (channels 3, 7, and 9) and Macon (channel 13) to the north, Tallahassee (channels 6 and 11) to the south, and Savannah (channels 3, 9, and 11) and Jacksonville/Brunswick (channels 4, 7, and 12) to the east. This created a large "doughnut" in southwestern Georgia where there could only be one VHF license.
All of this made expansion of broadcast television channels into the UHF band inevitable, though the technology and broadcasting characteristics of UHF was at this time largely unproven. Even the television standard to use to broadcast on UHF was in question at the time of the 1948 FCC freeze. With the knowledge that UHF channel allocation would be necessary to expand television coverage, and with the knowledge that by 1949 VHF television was an entrenched standard, the FCC proposed intermixture, licensing both VHF and UHF stations in a single city. Intermixture would rely on consumers rapidly adopting television sets with UHF tuning capability, and on the base assumption that a UHF television station was functionally equivalent to a VHF one.
A fourth station, the FCC ruled, would have to broadcast on the UHF band. Hundreds of new UHF stations began operations, but many of these stations quickly folded because television set manufacturers were not required to include a UHF tuner until 1964 as part of the All-Channel Act. Most viewers could not receive UHF stations, and most advertisers would not advertise on stations which few could view. Without the advertising revenue enjoyed by the VHF stations, many UHF station owners either returned their station licenses to the FCC, attempted to trade licenses with educational stations on VHF, attempted to purchase a VHF station in a nearby market to move into theirs, or cut operating costs in attempts to stay in business .
It took five years for the US to grow from 108 stations to more than 550. New stations came on line slowly, only five by the end of November 1952. The Sixth Report and Order required some existing television stations to change channels, but only a few existing VHF stations were required to move to UHF, and a handful of VHF channels were deleted altogether in smaller media markets like Peoria, Fresno, Bakersfield and Fort Wayne, Indiana to create markets which were UHF "islands." The report also set aside a number of channels for the newly emerging field of educational television, which hindered struggling ABC and DuMont's quest for affiliates in the more desirable markets where VHF channels were reserved for non-commercial use.
How Well Does High VHF Work for DTV? TV Technology April 9, 2008 (Retrieved on January 1, 2009) The FCC has long discouraged the digital allocation on low-VHF channels for several reasons: higher ambient noise, interference with FM radio (channel 6 borders FM at 88 MHz), and larger antenna size required for these channels.Seventh Further Notice of Proposed Rulemaking Federal Communications Commission October 20, 2006 (Retrieved on January 29, 2009) After the transition, many viewers using "high-definition" antennas have reported problems receiving stations that broadcast on VHF channels. This is because some of the new antennas marketed as "HDTV antennas" from manufacturers such as Channel Master were only designed for channels 7–51 and are more compact than their channel 2–69 counterparts.
KSWO-TV shut down its analog signal, over VHF channel 7, on February 17, 2009, the original target date in which full-power television stations in the United States were to transition from analog to digital broadcasts under federal mandate. The station cited the need to place its digital antenna where the analog transmitter was located for its decision to go forward with the transition on the originally scheduled date, despite a Congressional vote the previous month that pushed back the analog-to-digital cutoff for full-power stations to June 12. The station's digital signal remained on its pre- transition VHF channel 11. Through the use of PSIP, digital television receivers display the station's virtual channel as its former VHF analog channel 7.
COFDM is also used for other radio standards, for Digital Audio Broadcasting (DAB), the standard for digital audio broadcasting at VHF frequencies, for Digital Radio Mondiale (DRM), the standard for digital broadcasting at shortwave and medium wave frequencies (below 30 MHz) and for DRM+ a more recently introduced standard for digital audio broadcasting at VHF frequencies. (30 to 174 MHz) The USA again uses an alternate standard, a proprietary system developed by iBiquity dubbed HD Radio. However, it uses COFDM as the underlying broadcast technology to add digital audio to AM (medium wave) and FM broadcasts. Both Digital Radio Mondiale and HD Radio are classified as in-band on-channel systems, unlike Eureka 147 (DAB: Digital Audio Broadcasting) which uses separate VHF or UHF frequency bands instead.
However, Mid-America was not able to profitably run KSLN-TV, just as Prairie States had failed. In late October 1965, the station announced it would ask for authority to "temporarily" cease operations effective November 1 and begin a fight to get a VHF television channel allocated to Salina; channel 34's management said that "every possible effort" would be made to reopen KSLN-TV as a VHF station. The KSLN bid to bring VHF television to Salina—whose assigned channels were 18, 34, and 44—would have changed the educational assignment of channel 9 at Lincoln Center to channel 6, and substituted commercial channel 9 for channel 34 in Salina. The Lincoln Center assignment would necessitate a waiver of station spacing rules.
KUHT's digital signal originally began broadcasting on VHF channel 9 on May 12, 2001. The station discontinued regular programming on its analog signal, over VHF channel 8, on June 12, 2009, as part of the federally mandated transition from analog to digital television.List of Digital Full- Power Stations The station's digital signal relocated from its pre-transition VHF channel 9 to channel 8 for post-transition operations.CDBS Print In 2009, KUHT filed with the FCC for construction permits to build low-powered digital transmitters in Beaumont (K24KQ, channel 24)FCC data: new channel 24 in Beaumont and Victoria (K29JI-D, channel 29),FCC data: K29JI-D new channel 29 in Victoria in order to provide over-the-air PBS service to both cities.
Most of the rest of the country ("1/2") would be able to receive a third VHF channel. Other areas would be designated as "UHF islands" since they were too close to larger cities for VHF service. The "2" networks became CBS and NBC, "+1" represented non-commercial educational stations, and "1/2" became ABC (which was the weakest network usually winding up with the UHF allocation where no VHF was available). However, Utica was sandwiched between Albany, New York (channels 4 (later 6) and 10, later joined by 13) to the east, Syracuse (channels 3, 5, and 9) to the west, Binghamton (channel 12) to the south, and Watertown (channel 7) and Plattsburgh (channels 3 and 5) to the north.
The VHF band is the first band at which efficient transmitting antennas are small enough that they can be mounted on vehicles and portable devices, so the band is used for two-way land mobile radio systems, such as walkie-talkies, and two way radio communication with aircraft (Airband) and ships (marine radio). Occasionally, when conditions are right, VHF waves can travel long distances by tropospheric ducting due to refraction by temperature gradients in the atmosphere.
WROC-TV discontinued regular programming on its analog signal, over VHF channel 8, at 11:35 p.m. on June 12, 2009 (following the late newscast), the official date in which full-power television stations in the United States transitioned from analog to digital broadcasts under federal mandate. The station's digital signal remained on its pre-transition UHF channel 45. Through the use of PSIP, digital television receivers display the station's virtual channel as its former VHF analog channel 8.
KTTW, virtual and VHF digital channel 7, is a Fox-affiliated television station licensed to Sioux Falls, South Dakota, United States. The station is owned by a group of local investors. KTTW's studios are located on West 11th Street in Sioux Falls, and its transmitter is located in Rowena, South Dakota. KTTM (virtual and VHF digital channel 12) in Huron operates as a full-time satellite of KTTW; this station's transmitter is located near Alpena, South Dakota.
KFPH-TV shut down its analog signal, over VHF channel 13, on September 18, 2008, citing a lack of space at its transmitter site to accommodate the analog transmitter, its digital channel 27 transmitter, and the new digital channel 13 transmitter; additionally, winter weather conditions rendered it impossible to perform work during the last 90 days before the conclusion of the digital transition. The station's digital signal relocated from its pre-transition UHF channel 27 to VHF channel 13.
There were barely more than 100 stations operating at the end of the freeze as of 1952, concentrated in many (but not all) major cities. After four years of deliberation, the FCC ended the license freeze. It reorganized the UHF band for television, then began handing out broadcasting licenses on both the UHF and VHF bands, with the highest concentration of license grants and station sign-ons occurring between 1953 and 1956. Many successful VHF stations launched.
The senior pilots monitor traffic in the local airspace and give advisories over VHF frequency to the pilots flying in circuits and around the area. The main Apron parking capacity is 100 M x 75 M. There are currently no navigational nor visual aids nor night landing facilities available on the airstrip other than the VHF communication and the windsock. Advisory tower at Baramati Airport.

Matla-ul-fajr can use 100 different frequencies in the VHF band to operate in jammed environments. "Panjereh Magazine" weekly number 38 In the same year, a project to enhance the capabilities of radar was started by SAIRAN and Isfahan University of Technology. Production of this model called Matla-ul-fajr 2 was started in 2012. State-owned Mashregh News reported that Matla-ul-fajr 2 is a solid state 3D radar operating in VHF band.
Canal 13 is a Chilean free-to-air television channel. It was launched on 21 August 1959, on VHF channel 2 of Santiago, in a broadcast led by a group of engineers from the Pontifical Catholic University of Chile. Subsequently, the TV station moved its frequency to VHF channel 13, which gave rise to its current name. In its beginnings, one of its most important milestones was the broadcast of the 1962 FIFA World Cup, held in Chile.
Geraldton Volunteer Marine Rescue (active on weekends and public holidays) monitor marine radio frequency 27.88 MHz and VHF Channel 16. Local groups also monitor other frequencies such as 27.90 MHz, 27.91 MHz and VHF channels 72 and 73, as well as their own channels. The Geraldton Regional Art Gallery opened in 1984 and was one of the first "A Class" regional galleries in Australia. The Aquarena is a public swimming facility managed by the City of Greater Geraldton.
That watchkeeping requirement had been scheduled to end on February 1, 2005. IMO and ITU both require that the DSC-equipped MF/HF and VHF radios be externally connected to a satellite navigation receiver (GPS). That connection will ensure accurate location information is sent to a rescue coordination center if a distress alert is transmitted. The FCC requires that all new VHF and MF/HF maritime radiotelephones type accepted after June 1999 have at least a basic DSC capability.
This capability allows the lighting system to remain passive (in the off position) the vast majority of the time thus preserving the dark sky environment while adhering to strict safety standards set out by the FAA. Secondary WarningAudio Broadcast: If the initial warning does not result in the pilot altering the flight path, a programmable VHF radio broadcasts an additional obstruction warning directly to the cockpit. The VHF warning frequencies are adjusted based on local requirements.
WTVH shut down its analog signal, over VHF channel 5, on June 12, 2009, the official date in which full-power television in the United States transitioned from analog to digital broadcasts under federal mandate. The station's digital signal remained on its pre-transition UHF channel 47. Through the use of PSIP, digital television receivers display the station's virtual channel as its former VHF analog channel 5. In January 2015, WTVH's second digital subchannel began carrying the Grit network.
WAFB shut down its analog signal, over VHF channel 9, on June 12, 2009, the official date in which full-power television stations in the United States transitioned from analog to digital broadcasts under federal mandate. The station's digital signal relocated from its pre-transition UHF channel 46 to VHF channel 9. With the new digital channel, WAFB rebroadcasts WBXH on channel 9.4 and, before the launch of Bounce TV affiliate September 2011, weather on channel 9.2.
On the transmission side, UHF stations were also found to have issues involving transmission distance and strength. The FCC tried solving this problem by allowing the lower powered UHF stations to broadcast with more power, but VHF continued to have more stations. Advertisers soon caught on to this and did most of their business with VHF stations since UHF tuner adoption was flagging.Sterling, C. H., & Kittross, J. M. (1990). Stay Tuned: A Concise History of American Broadcasting (2nd ed.).
Since the price of CB was dropping and VHF Marine Band was still expensive, many boaters installed CB radios. Business caught on to this market, and introduced marine CBs containing a weather band (WX). Whether the Coast Guard should monitor CB radio caused much controversy, but they did, using Motorola base stations at their search and rescue stations. The Coast Guard stopped this practice in the late 1980s and recommends VHF Marine Band radios for boaters.
WSTM-TV shut down its analog signal, over VHF channel 3, on June 12, 2009. Two days later, the station's digital signal moved from its pre-transition UHF channel 54, which was among the high band UHF channels (52-69) that were removed from broadcasting use as a result of the transition, to UHF channel 24. Through the use of PSIP, digital television receivers display the station's virtual channel as its former VHF analog channel 3.
WRAL-TV discontinued regular programming on its analog signal, over VHF channel 5, at 12:55 p.m. on June 12, 2009, the official date in which full-power television stations in the United States transitioned from analog to digital broadcasts under federal mandate. The station's digital signal remained on its pre-transition UHF channel 48. Through the use of PSIP, digital television receivers continues to display the station's virtual channel as its former VHF analog channel 5.1.
This time, the police are there and enter a shootout with the men in which all of the henchmen are killed. Meanwhile, London Air Traffic Control gets radio contact with the Concorde on a VHF frequence. Captain Scott on the Concorde then descends the aircraft to a lower altitude below 12,000 feet, but London now can't get Concorde on the VHF frequency, either. Brody and Jean reach the American Consul and she begins describing what happened.
WRTV shut down its analog signal, over VHF channel 6, at 8 a.m. on June 12, 2009, the official date in which full-power television stations in the United States transitioned from analog to digital broadcasts under federal mandate. The station's digital signal continued to broadcast on its pre- transition UHF channel 25.FCC Form 387 Through the use of PSIP, digital television receivers display the station's virtual channel as its former VHF analog channel 6.
Guernsey Coastguard is also based within the Joint Emergency Services control centre and maintains and 24/7 watch on Channel 16 VHF and its local frequency, VHF channel 20. Guernsey Costguard also broadcasts marine Navigation Warnings for the terrestrial waters within the Bailiwick of Guernsey. JESCC staff are all trained in emergency call handling, dispatch of all services land-based emergency services and Coastguard Search and rescue. Staff in JESCC are civilians and not members of the Guernsey Police.
The VHF viruses are spread in a variety of ways. Some may be transmitted to humans through a respiratory route. According to Soviet defector Ken Alibek, Soviet scientists concluded China may have tried to weaponize a VHF virus during the late 1980s but discontinued to do so after an outbreak. The virus is considered by military medical planners to have a potential for aerosol dissemination, weaponization, or likelihood for confusion with similar agents that might be weaponized.
KTTZ-TV (as KTXT-TV) shut down its analog signal, over VHF channel 5, at 4:30 p.m. on February 5, 2009, four months before most full-power television stations in the United States transitioned from analog to digital broadcasts under federal mandate on June 12\. The station's digital signal remained on its pre-transition UHF channel 39. Through the use of PSIP, digital television receivers display the station's virtual channel as its former VHF analog channel 5\.
WDBD shut down its analog signal, over UHF channel 40, on May 4, 2009.List of Digital Full-Power Stations The station's digital signal relocated from its pre-transition VHF channel 6 to UHF channel 40. WDBD increased the new digital signal's power to full-powered as opposed to the special temporary authority operation before the switchover. That change was needed because its previous VHF digital signal had a tough time reaching the outer suburbs of Jackson.
KYES-TV shut down its analog signal, over VHF channel 5, on June 13, 2009, one day later. The station's digital signal relocated from its pre- transition VHF channel 6 to channel 5.Jeremy Lansman, on-air call-in show, 12 June 2009, KYES-TV5. In 2019, KYES's transmitter was moved to the same tower as KTUU's as part of the FCC's spectrum re-allocation and an overall want by Gray to combine transmission facilities between the two stations.
The system is compatible with all current U.S. and allied VHF-FM radios in the SC, non-secure mode. The SINCGARS operates on any of 2320 channels between 30 and 88 megahertz (MHz) with a channel separation of 25 kilohertz (kHz). It accepts either digital or analog inputs and superimposes the signal onto a radio frequency (RF) carrier wave. In FH mode, the input changes frequency about 100 times per second over portions of the tactical VHF-FM range.
It opted to keep the higher-rated WTOL and sold WNWO to Barrington Broadcasting, who acquired that station in 2006. WTOL's broadcasts became digital-only, effective June 12, 2009. Digital channel 11 transmits at a lower power than it did on digital channel 17, so in some locations, there has been a reduction in coverage. Many VHF stations are applying to the FCC for power increases to restore their coverage area after moving from UHF back to VHF.
KFVS-TV shut down its analog signal, over VHF channel 12, on June 12, 2009, the official date in which full-power television stations in the United States transitioned from analog to digital broadcasts under federal mandate. The station's digital signal relocated from its pre-transition UHF channel 57, which was among the high band UHF channels (52-69) that were removed from broadcasting use as a result of the transition, to its analog-era VHF channel 12.
WHEC-TV discontinued regular programming on its analog signal, over VHF channel 10, on June 12, 2009, the official date in which full-power television in the United States transitioned from analog to digital broadcasts under federal mandate. The station's digital signal relocated from its pre-transition UHF channel 58, which was among the high band UHF channels (52-69) that were removed from broadcasting use as a result of the transition, to its analog-era VHF channel 10.
Semiconductor amplifiers have overwhelmingly displaced valve amplifiers for low and medium power applications at all frequencies. Valves continue to be used in some high-power, high-frequency amplifiers used for short wave broadcasting, VHF and UHF TV and (VHF) FM radio, also in existing "radar, countermeasures equipment, or communications equipment" using specially designed valves, such as the klystron, gyrotron, traveling-wave tube, and crossed-field amplifier; however, new designs for such products are now invariably semiconductor-based.
Mirroring the changes in the RP25A Sovereign described below, the later RP37A VHF Herald had a revised FM tuner; recognisable because it has a clear plastic cover rather than an aluminium enclosure. At a similar time, the loudspeaker was changed from a grey painted unit made by Goodmans to a silver-framed Celestion or a unit supplied by Elac which was recognisable by the large ceramic magnet assembly. This latter loudspeaker was only ever fitted to the VHF Herald.
A few twin-masted sailing vessels have the space to erect a "Tee" antenna or an inverted "L" between masts. These antenna configurations are more common on merchant ships. A handheld amateur VHF radio transceiver ready for "maritime mobile" use on a 28' yacht. For VHF and UHF operation, one option is to mount a small yagi antenna to a pole 1–2 m (3–6 ft) long and haul this to the masthead using a flag halyard.
The lifeboat has a variety of equipment to help rescue vessels and save lives. The kit includes advanced medical kit including an automatic external defibrillator (AED) and oxygen, search lights and thermal imaging cameras. There is also a VHF direction-finding equipment for homing in on a casualty vessel’s radio transmissions, a chart plotter, tow lines, radar and depth sounder. The Lifeboat also features VHF radios for communications with the Coastguard, Gosport Lifeboat Station and casualties.
In telecommunication, a maritime broadcast communications net is a communications net that is used for international distress calling, including international lifeboat, lifecraft, and survival-craft high frequency (HF); aeronautical emergency very high frequency (VHF); survival ultra high frequency (UHF); international calling and safety very high frequency (VHF); combined scene-of-search-and-rescue; and other similar and related purposes. Note: Basic international distress calling is performed at either medium frequency (MF) or at high frequency (HF).

This is because low VHF (band I) has a lot of RF noise, which is worse on the lowest channels. The radio tower was built in 1966. fcc.gov. Retrieved March 6, 2017.
On August 31, 2011, when Canadian television stations in CRTC-designated mandatory markets transitioned from analogue to digital broadcasts, CHMI-TV flash cut its digital signal into operation on VHF channel 13.
The armour protects against 7.62 calibre bullets. A 2061 VHF radio is for communication. The wheels are mine and bullet resistant. There is an option to mount a 12.7-calibre machine gun.
There are no landlines or cellular service in the area; radio telephones and satellite phones only. First Nations, loggers, roadbuilders and government officials all rely extensively on the use of VHF radios.
When solar activity is sufficiently high, the MUF (Maximum Usable Frequency) rises, hence the ionisation density is sufficient to reflect signals well into the 30-60 MHz VHF spectrum. Since the MUF progressively increases, F2 reception on lower frequencies can indicate potential low band 45-55 MHz VHF TV as well as VHF amateur radio paths. A rising MUF will initially affect the 27 MHz CB band, and the amateur 28 MHz 10 meters band before reaching 45-55 MHz TV and the 6 meters amateur band. The F2 MUF generally increases at a slower rate compared to the Es MUF. Since the height of the F2 layer is some 200 miles (320 km), it follows that single-hop F2 signals will be received at thousands rather than hundreds of miles. A single-hop F2 signal will usually be around 2,000 miles (3,200 km) minimum. A maximum F2 single-hop can reach up to approximately 3,000 miles (4,800 km). Multi-hop F2 propagation has enabled Band 1 VHF reception to over 11,000 miles (17,700 km).
WFAA became the first television station in the United States to broadcast their digital television signal on a VHF channel on February 27, 1998 at 2:17 p.m., when it began test broadcasts on VHF channel 9; the following day on February 28, it became the nation's first television station to broadcast a local news program in high definition. When the transmission tests began, the digital feed's Channel 9 assignment was already in use by Dallas area hospitals; this would result in Baylor University Medical Center and Methodist Dallas Medical Center having to reconfigure their telemetry systems to different frequencies before WFAA began full-time digital transmissions on March 16 (when it became the country's first commercial station to begin regular digital broadcasts on the VHF band) as the station's assigned digital channel corresponded to a portion of the broadcast spectrum utilized by the hospitals for their wireless medical equipment, creating RF interference issues that notably disrupted several wireless heart monitors at both facilities. WFAA shut down its analog signal, over VHF channel 8, at 12:03 p.m.
Under this plan, almost all of the country would be able to receive two commercial VHF channels plus one noncommercial channel. Most of the rest of the country ("1/2") would be able to receive a third VHF channel. Other areas would be designated as "UHF islands" since they were too close to larger cities for VHF service. The "2" networks became CBS and NBC, "+1" represented non-commercial educational stations, and "1/2" became ABC (which was the weakest network usually winding up with the UHF allocation where no VHF was available). However, Watertown was sandwiched between Syracuse (channels 3, 8, later 5, and 9) to the south, Rochester (channels 6, later 8, 10, and 13) to the west, Utica (channel 13, later 2) and Albany (channel 4, later 6, later joined by 10 and 13) to the southeast, Burlington/Plattsburgh (channels 3 and 5) to the east, Kingston (channel 11) to the northwest, Ottawa (channels 4, 9, and 13) to the north, and Montreal (channels 2, 6, 10, and 12) to the northeast.

KZFW-LP, VHF analog channel 6, is a low-powered Aliento-affiliated television station licensed to Dallas, Texas, United States. The station transmits a directional signal towards Dallas, so as to not interfere with nearby KBFW-LP (also on channel 6), which covers Fort Worth. The station is what is colloquially known as a "Franken-FM" station - a television station that is used as an FM radio station. This is due to the FM broadcast band being located adjacent to the VHF spectrum.
KRSD-TV, VHF analog channel 7, was a television station licensed to Rapid City, South Dakota, United States. KDSJ-TV (VHF analog channel 5) in Lead, was a satellite of KRSD. Owned by Heart of the Black Hills Stations, the two stations went on air in 1958 and 1960, respectively, and ceased broadcasting in 1976. Their licenses were not renewed by the Federal Communications Commission as a result of a years-long proceeding involving serial deficiencies in their technical operation.
KLBK-TV shut down its analog signal, over VHF channel 13, on February 17, 2009, the original target date in which full-power television stations in the United States were to transition from analog to digital broadcasts under federal mandate (which was later pushed back to June 12, 2009). The station's digital signal remained on its pre-transition UHF channel 40. Through the use of PSIP, digital television receivers display the station's virtual channel as its former VHF analog channel 13.
The Abergavenny transmitting station was originally built by the IBA in 1969 as a relay for BBC and ITV VHF 405-line analogue television. It consists of a 46 m guyed lattice mast carrying the aerials at the top. This structure was built on a 440 m hill known as Gilwern Hill overlooking the towns of Gilwern and Abergavenny in Monmouthshire, South Wales. The band III VHF television feeds were provided off-air from St. Hilary and Wenvoe, both near Cardiff.
KCOY-TV shut down its analog signal, over VHF channel 12, on February 17, 2009, the original target date in which full-power television stations in the United States were to transition from analog to digital broadcasts under federal mandate (which was later pushed back to June 12, 2009). The station's digital signal remained on its pre-transition UHF channel 19. Through the use of PSIP, digital television receivers display the station's virtual channel as its former VHF analog channel 12.
Besides the ISR and CSR observations, the main JRO system has been used as radio telescope, a VHF heater, and planetary radar. As radio telescope the main array has been used to study the Sun, radio stars (like Hydra), magnetosphere synchrotron radiation, Jupiter radiation. In the 1960s JRO was used as to study Venus and the surface of the Moon and more recently the Sun. Recently, the equatorial electrojet has been weakly modulated using JRO as a VHF heater to generate VLF waves.
If the radios are used mainly inside buildings, then UHF is likely the best solution since its shorter wavelength travels through small openings in the building better. There are also repeaters that can be installed that can relay any frequencies signal (VHF or UHF) to increase the communication distance. There are more available channels with UHF. Since the range of UHF is also not as far as VHF under most conditions, there is less chance of distant radios interfering with the signal.
KEYT-TV shut down its analog signal, over VHF channel 3, on February 17, 2009, the original target date in which full-power television stations in the United States were to transition from analog to digital broadcasts under federal mandate (which was later pushed back to June 12, 2009). The station's digital signal remained on its pre-transition UHF channel 27. Through the use of PSIP, digital television receivers display the station's virtual channel as its former VHF analog channel 3.

After the station filed its minor change application for a construction permit, stating the channel move,CDBS Print. Licensing.fcc.gov. on November 9, 2009, WHDH terminated operations on VHF channel 7 and now permanently operates solely on channel 42 (mapping to virtual channel 7 via PSIP). The equipment for the channel 7 digital transmitter was shipped to Miami for use by sister station WSVN, which continues to broadcast on VHF 7 with few complaints due to South Florida's less-varied terrain.
In July 1961, WHEN-TV moved to channel 5, swapping channel locations with WROC-TV in Rochester as the Federal Communications Commission (FCC) revised its Upstate New York allocation table to provide more VHF service in the two cities."Final orders add vhf to three markets." Broadcasting - Telecasting, August 7, 1961, pg. 55. In 1963, the WHEN stations moved from their original Court Street studios into a new state-of-the-art facility on James Street near WSYR (AM)-FM-TV's studios.
Some needed to rescan, and others needed a VHF antenna. WJLA-TV applied on August 29, 2009 for special authorization by the FCC to increase its effective radiated power (ERP) to 52 kW. The power increase was put into effect on September 18, 2009. WJLA-TV already ran 30 kW of ERP, which was higher than the other three VHF stations in the area: WUSA (12.6 kW), WBAL-TV (5 kW), and WJZ-TV (28.8 kW) (post transition power levels).
Belmont, CA: Wadsworth. While the more-established broadcasters were operating profitably on VHF channels as affiliates of the two largest TV networks (at the time, NBC and CBS), most of the original UHF local stations of the 1950s soon went bankrupt, limited by the range their signals could travel, the lack of UHF tuners in most TV sets and the paucity of advertisers willing to spend money on them. UHF stations fell quickly behind the VHF stations, losing $10,500,000 in 1953.
The end of the war brought rapid expansion in the nascent broadcast television industry. Thirteen VHF channels was found to be insufficient to support the desired expansion of broadcast television across the United States. Interference and channel crowding in densely populated areas (such as the eastern mid-Atlantic states) was a particular problem. This bandwidth crunch was made even worse by the need to re-allocate VHF Channel 1 to land-mobile radio systems in 1948 due to radio-interference problems.
KERO-TV, virtual channel 23 (VHF digital channel 10), is an ABC-affiliated television station licensed to Bakersfield, California, United States. The station is owned by the E. W. Scripps Company. KERO-TV's studios are located on 21st Street in Downtown Bakersfield, and its transmitter is located atop Breckenridge Mountain. KERO-TV operates digital translator KZKC-LD (channel 28), which allows homes with issues receiving KERO-TV's VHF signal or only a UHF antenna to receive KERO-TV in some form.
The system coverage range is similar to other VHF applications. The range of any VHF radio is determined by multiple factors, the primary factors are: the height and quality of the transmitting antenna and the height and quality of the receiving antenna. Its propagation is better than that of radar, due to the longer wavelength, so it is possible to reach around bends and behind islands if the land masses are not too high. The look-ahead distance at sea is nominally .
A shortwave antenna was installed in the 1970s, and is still in use by the WA VHF Group. After Cyclone Tracy hit Darwin in 1975, destroying or disabling much of its communications infrastructure, the WA VHF Group helped provided communications between Darwin and Perth. In the 1980s an antenna was added to the Stores building, which became the control centre for the State Emergency Service. Since 2002 Wireless Hill has been home to Capital Community Radio's studios and one of their transmitters.
The USB system did not completely replace all other radio transmitters on Apollo. Apollo still used VHF between astronauts and the Lunar Module (LM) and Lunar Roving Vehicle during extra- vehicular activity; between the lander and the command module, and between the spacecraft and Earth stations in the orbital and recovery phases. As a backup the CM could measure range to the LM over the VHF voice link. The spacecraft radar systems operated on frequencies separate from those of the USB.
KSBY shut down its analog signal, over VHF channel 6, on February 17, 2009, the original target date on which full-power television stations in the United States were to transition from analog to digital broadcasts under a federal mandate (which was later pushed back to June 12, 2009). The station's digital signal remained on its pre-transition UHF channel 15. Through the use of PSIP, digital television receivers display the station's virtual channel as its former VHF analog channel 6.
Signs and symptoms of VHFs include (by definition) fever and bleeding. Manifestations of VHF often also include flushing of the face and chest, small red or purple spots (petechiae), bleeding, swelling caused by edema, low blood pressure (hypotension), and shock. Malaise, muscle pain, headache, vomiting, and diarrhea occur frequently. The severity of symptoms varies with the type of virus. The “VHF syndrome” (capillary leak, bleeding diathesis, and circulatory compromise leading to shock) appears in a majority of people with filovirus hemorrhagic fevers (e.g.
KTNV-TV shut down its analog signal, over VHF channel 13, on June 12, 2009, the official date in which full-power television stations in the United States transitioned from analog to digital broadcasts under federal mandate. The station's digital signal relocated from its pre-transition VHF channel 12 to channel 13 for post-transition operations. As with all of Journal Communications' television stations, the station also added the "-TV" suffix to its callsign following the transition to become KTNV-TV.
It is capable of being beached in an emergency without sustaining damage to engines or steering gear. The Atlantic 85 is fitted with radar and VHF direction finding equipment and can be operated safely in daylight in a force 6/7 and at night in a force 5/6. The Atlantic 85 also has intercom communications between the crew and VHF radio via their helmets, DGPS & Chartplotter. It also carries a searchlight, night-vision equipment and illuminating paraflares for night-time operations.
The radio modems of the SATELLINE-EASy -family are suitable for high-end applications requiring a longer range. With these radio modems, a reliable radio modem network can be built across vast areas. Radio modems are available for both the UHF (330 - 473 MHz) and VHF (135 - 174 MHz and 218 - 238 MHz) frequency bands. The modems using the VHF frequencies are specifically designed for data applications, where large distances with obstacles such as Mountains and valleys are to be spanned.
Aircraft are operated using two major methods; positive control and procedural control. Positive control is used in areas which have radar and so is commonly referred to as radar control. The controller "sees" the airplanes in the control area and uses VHF voice to provide instructions to the flight crews to ensure separation. Because the position of the aircraft is updated frequently and VHF voice contact timely, separation standards (the distance by which one aircraft must be separated from another) are less.
The station's first formal program was shown on March 22 to a group of RCA executives, television dealers, and radio station personnel at the Stevens House Hotel in downtown Lancaster. WGAL was a major beneficiary of a quirk in the Federal Communications Commission's (FCC) plan for allocating stations. In the early days of broadcast television, there were twelve VHF channels available and 69 UHF channels (later reduced to 55 in 1983). The VHF bands were more desirable because they carried longer distances.
According to a 2009 CRTC decision, CFJC- TV is not required to activate its digital signal, as Kamloops was not a mandatory market for digital conversion, which took place in most other markets on August 31, 2011.Digital Television – Office of Consumer Affairs (OCA) When CFJC signs on its digital signal, the station will broadcast on VHF channel 13. Through the use of PSIP, digital television receivers will display CFJC-TV's virtual channel as its analogue-era VHF channel 4.

In 1983, the Hobbys reorganized their broadcast holdings as H&C; Communications after they sold off the Houston Post. H&C; then sold WTOK to United Broadcasting who also owned KARK-TV in Little Rock, Arkansas in 1984. Although most media markets were allocated two VHF commercial channels and one VHF noncommercial channel, what would become of the Meridian media market was sandwiched between Columbus–Tupelo (channels 2, 4, and 9) to the north, Jackson (channel 3 and later channel 12) to the west, Hattiesburg–Laurel (channel 9, later 7) and Mobile (channels 3, 5, and 10) to the south, and Birmingham (channels 6, 10, and 13) and Montgomery (channels 2, 8, and 12) to the east. This created a "doughnut" in East Central Mississippi where there was only one VHF license available.
WCPO-TV discontinued regular programming on its analog signal, over VHF channel 9, on June 12, 2009, as part of the federally mandated transition from analog to digital television. The station's digital signal remained on its pre-transition VHF channel 10,CDBS Print using PSIP to display WCPO-TV's virtual channel as 9 on digital television receivers. Since many viewers had reception issues after the digital transition, even with an increase of power just weeks after the transition, the station filed a Petition for Rulemaking to abandon VHF channel 10 and move to UHF channel 22.Petition for Rulemaking by WCPO-TV On October 7, 2009, the FCC issued a "Notice of Proposed Rulemaking" for WCPO-TV, which gives the public 25 days to comment on the proposed channel change.
The station's original mast, built from early 1954, was tall and first broadcast television transmissions, albeit temporarily, from February 1955. VHF (FM) radio broadcasts began on a test basis from December 22 1956, in order to allow East Anglia to receive programmes on VHF over the Christmas period. The BBC Light Programme was not available during this test phase, and there were warnings that the service would occasionally be interrupted for engineering reasons. The station began broadcasting regular programmes from Norwich purely for East Anglian audiences on the Midlands Home Service from Tuesday 5 February 1957, and the transmitter went to full power for VHF from 6.35pm on Tuesday 30 April 1957. The transmission site is located at 52° 31' 3.9" North, 1° 8' 19.3" East (National Grid Reference: TM131958).

On September 1, 2010, another channel realignment took place which added three of MPTV's digital subchannels to WMVS' signal bandwidth, while a standard definition simulcast of WMVS' 10.1 feed was added to digital subchannel 36.2 for over-the-air viewers who were unable to receive WMVS' VHF signal since the conversion (or only have UHF antennas; outside of WMVS and WIWN, all of Milwaukee's other stations transmit on UHF signals), an issue that has plagued many stations continuing to broadcast on VHF post- transition.Changes are Many for MPTV in September, Milwaukee Public Television, August 31, 2010. The picture format on 10.1 was also reduced from 1080i to 720p to enable multicasting on WMVS' bandwidth.
Other areas would be designated as "UHF islands" since they were too close to larger cities for VHF service. The "2" networks became CBS and NBC, "+1" represented non-commercial educational stations, and "1/2" became ABC (which was the weakest network usually winding up with the UHF allocation where no VHF was available). However, what would become the Harrisburg/Lancaster/York market was sandwiched between Philadelphia (channels 3, 6, 10, and 12) to the east, Johnstown/Altoona/State College (channels 6 and 10) to the west, Scranton/Wilkes-Barre (a UHF island) to the north, and Baltimore (channels 2, 11, and 13) and Washington, D.C. (channels 4, 5, 7, and 9) to the south. This created a large "doughnut" in South Central Pennsylvania where there could be only one VHF license.

WCVB-TV shut down its analog signal, over VHF channel 5, on June 12, 2009, the official date in which full-power television stations in the United States transitioned from analog to digital broadcasts under federal mandate. The station's digital signal continued to broadcast on its pre-transition UHF channel 20.CDBS Print Through the use of PSIP, digital television receivers display the station's virtual channel as its former VHF analog channel 5. Its analog signal provided nightlight service (DTV information loops) until July 12, 2009.
KMSP-TV originally broadcast its digital signal on UHF channel 26, which was remapped as virtual channel 9 on digital television receivers through the use of PSIP. The station shut down its analog signal, over VHF channel 9, on June 12, 2009, the official date in which full-power television stations in the United States transitioned from analog to digital broadcasts under federal mandate. The station's digital signal relocated from its pre- transition UHF channel 26 to VHF channel 9 for post-transition operations.
In North American VHF radio contests, rover stations are those that travel from one Maidenhead grid locator to another. The rules of major VHF contests allow these stations to make two-way contacts with other stations from each unique grid locator in which they travel. Rover activity is responsible for contest operations from many grid locators that might otherwise not have any active contest stations. A captive rover is a rover station whose contest operation is intended specifically or primarily for the benefit of another fixed station.
"Filipino Monkey" is a taunt used by radio pranksters in maritime radio transmissions since at least the 1980s, especially in the Persian Gulf. This taunt is also used as a name for pranksters who make odd, confusing, or even threatening calls on VHF marine channel 16, which is the VHF calling and distress channel. Before the advent of GMDSS, ships at sea were required to monitor the channel, which is meant to be used only to make contact before changing to a working channel.
KRIS-TV began broadcasting on May 22, 1956 as the first VHF television station in the area beating former rival KZTV by four months. It aired an analog signal on VHF channel 6 and had studios on South Staples Street in Downtown Corpus Christi. The channel has always been an NBC affiliate but shared secondary ABC status with KZTV until KIII launched on May 4, 1964. In 1989 it was a secondary Fox affiliate carrying a few shows during syndicated hours on the weekends.
WTVI began broadcasting its digital signal on VHF channel 11, carrying four digital subchannels, including one high-definition channel. WTVI was the first television station in Charlotte to produce programming in high- definition in 2000. The station shut down its analog signal, over UHF channel 42, on February 17, 2009, the original target date in which full-power television stations in the United States were to transition from analog to digital broadcasts under federal mandate. The station's digital signal remained on its pre-transition VHF channel 11.
UHF frequencies are used for both analog and digital television broadcasts. UHF channels are typically given higher channel numbers, like the US arrangement with VHF channels 2 to 13, and UHF channels numbered 14 to 83. Compared with an equivalent VHF television transmitter, to cover the same geographic area with a UHF transmitter requires a higher effective radiated power, implying a more powerful transmitter or a more complex antenna. However, the additional channels allow more broadcasters in a given region without causing objectionable mutual interference.
This required a large number of stations to move out of their current VHF channel assignments. Moving from one UHF channel to another is a fairly simple exercise and generally costs little to accomplish. Moving from VHF to UHF is a much more expensive proposition, generally requiring all new equipment, and a dramatic increase in power in order to maintain the same service area. DTV offsets the latter to a great degree, with the current FCC power limitations at 1 MW for UHF, the former limits.
WETM-TV became the first station in Elmira to broadcast a high definition feed in 2005 with the launch of a digital signal on VHF channel 2. The station shut down its analog signal, over UHF channel 18, at 12:01 a.m. on June 12, 2009, the official date in which full-power television stations in the United States transitioned from analog to digital broadcasts under federal mandate. The station's digital signal relocated from its pre-transition VHF channel 2 to UHF channel 18.
WBRZ signed on the air on April 14, 1955, becoming the second television station in Baton Rouge, signing on exactly two years after CBS affiliate WAFB. It was also the longest running VHF outlet in Baton Rouge at the time, as WAFB originally broadcast on UHF channel 28 before moving to VHF channel 9 in 1960. WBRZ was a primary NBC affiliate, sharing ABC with WAFB. It began broadcasting in color seven months later, becoming the first Baton Rouge TV station to do so.
AIS transceivers automatically broadcast information, such as their position, speed, and navigational status, at regular intervals via a VHF transmitter built into the transceiver. The information originates from the ship's navigational sensors, typically its global navigation satellite system (GNSS) receiver and gyrocompass. Other information, such as the vessel name and VHF call sign, is programmed when installing the equipment and is also transmitted regularly. The signals are received by AIS transceivers fitted on other ships or on land based systems, such as VTS systems.
The GIA unit is a combined communications and navigation radio, and also serves as the primary data aggregator for the G1000 system. It provides a two-way VHF communications transceiver, a VHF navigation receiver with glideslope, a GPS receiver, and a variety of supporting processors. Each unit is paired with a GDU display, which acts as a controlling unit. The GIA 63W, found on many newer G1000 installations, is an updated version of the older GIA 63 which includes Wide Area Augmentation System support.
When built it transmitted BBC Television on the VHF 405-line system; the Croydon transmitter two miles away had been built some months earlier to broadcast ITV. When UHF transmissions started in 1964, first the new BBC2 and later both ITV and BBC1 were transmitted from Crystal Palace. 405-line VHF television was discontinued at the start of 1985, and from then all television broadcasts from Crystal Palace were on UHF. Crystal Palace did not transmit analogue Channel 5: this (alone) came from Croydon.
With the exception of yellow fever vaccine neither vaccines nor experimental vaccines are readily available. Prophylactic (preventive) ribavirin may be effective for some bunyavirus and arenavirus infections (available only as an investigational new drug (IND)). VHF isolation guidelines dictate that all VHF patients (with the exception of dengue patients) should be cared for using strict contact precautions, including hand hygiene, double gloves, gowns, shoe and leg coverings, and face shield or goggles. Lassa, CCHF, Ebola, and Marburg viruses may be particularly prone to nosocomial (hospital-based) spread.
WBKP shut down its analog signal, over VHF channel 5, on June 12, 2009, and "flash-cut" its digital signal into operation on VHF channel 5. Since it was granted an original construction permit after the Federal Communications Commission (FCC) finalized the DTV allotment plan on April 21, 1997, the station did not receive a companion channel for a digital television station. While transmitting in analog, its signal could be received across Lake Superior in Thunder Bay, Ontario and the surrounding areas in Canada.
WBUP shut down its analog signal, over VHF channel 10, on June 12, 2009, and "flash-cut" its digital signal into operation on VHF channel 10. Since it was granted an original construction permit after the Federal Communications Commission (FCC) finalized the DTV allotment plan on April 21, 1997, this station did not receive a companion channel for a digital television station. It then began offering a standard definition simulcast of WBKP on a new second digital subchannel in order to expand that station's broadcasting radius.
WCBI-TV shut down its analog signal, over VHF channel 4, on January 24, 2009, due to a transmitter problem. This was under a month before the original date of the federally-mandated transition from analog broadcasting to digital broadcasting (the original date was February 17; it would later get pushed back to June 12). The station's digital signal remained on its pre-transition UHF channel 35. Through the use of PSIP, digital television receivers display the station's virtual channel as its former VHF analog channel 4.
Due to different time zones in Australia, the bulletin goes live to air on the east coast at 5.30pm and a separate local edition is produced for the west coast. ABW commenced digital television transmission in January 2001, broadcasting on VHF Channel 12 while maintaining analogue transmission on VHF Channel 2. The analogue signal for ABW was shut off at 9.00am Western Standard Time, Tuesday, 16 April 2013. On April 6, 2018, weeknight weather presenter Rebecca Dollery stepped down from the ABC due to family reasons.
Alexander Turnquist (born 1988 in Idaho) is an American guitarist and composer. He has released original albums on the VHF record label as well as limited released titles on the Kning Disk imprint and Textura record label. Turnquist has been compared to guitarists Jack Rose, Alex De Grassi, Kaki King, and James Blackshaw, as well as contemporary composer Philip Glass. Turnquist's first widely released album, Faint at the Loudest Hour (VHF Records 2007), was given high marks, with an 8.2 from the popular music review website Pitchfork.
In 2003, KERA-TV signed on its digital signal on UHF channel 14. The station shut down its analog signal, over VHF channel 13, on June 12, 2009, the official date in which full-power television stations in the United States transitioned from analog to digital broadcasts under federal mandate. The station's digital signal remained on the UHF channel 14 allocation it used during the transition period. Through the use of PSIP, digital television receivers display the station's virtual channel as its former VHF analog channel 13.
After the Federal Communications Commission (FCC)'s four-year-long freeze on awarding television station licenses was lifted in 1952, two radio stations—KARM (1430 AM, now KYNO) and KFRE (940 AM, now KFIG) competed for the construction permit to operate a station on channel 12, the sole VHF allocation given to Fresno. KFRE won the permit,"Lee breaks stalemate, KFRE gets Fresno Vhf." Broadcasting - Telecasting, January 16, 1956, pg. 67. and the station first signed on the air on May 10, 1956 as KFRE-TV.
KGTV, virtual and VHF digital channel 10, is an ABC-affiliated television station licensed to San Diego, California, United States. The station is owned by the E. W. Scripps Company. KGTV's studios are located on Air Way in the Riverview-Webster section of San Diego, and its transmitter is located on Mount Soledad in La Jolla. KGTV operates digital translator KZSD-LD (channel 20), which allows homes with issues receiving KGTV's VHF signal or only a UHF antenna to receive KGTV in some form.
The most obvious feature is a configurable antennae platform mounted on the roof. This contains a large SATCOM dome containing a tracking dish that serves as the data uplink and downlink as the primary communications path for the motorcade. Also on the roof are smaller VHF antennas that serve as a repeater for the other motorcade elements as well as another communications path to local authorities and the onsite White House Communications Agency office. VHF antennae configuration changes according to the mission operational requirements.
WDIV-TV signed on its digital high-definition signal on UHF 45 on March 1, 1999. The station shut down its analog signal over VHF channel 4 on June 12, 2009, the official date in which full-power television stations in the United States transitioned from analog to digital broadcasts under federal mandate. The station's digital signal continued to broadcast on its pre-transition UHF channel 45. Through the use of PSIP, digital television receivers display the station's virtual channel as its former VHF analog channel 4.
No other commercial VHF station signed on in Pittsburgh until 1957, giving WDTV a de facto monopoly on television in the area.O'Brien, E. (July 1, 2003). Pittsburgh Area Radio and TV . Retrieved on December 28, 2006.

R-123 radio transceiver R-123 "Magnolia" (Р-123 «Магнолия») is a Soviet military HF/VHF radio transceiver designed for use in tanks and other armoured vehicles. The device was made in the Ryazan radio plant.
WILX-DT5 is the Antenna TV-affiliated fifth digital sub channel of WILX-TV, broadcasting in standard definition on VHF channel 10.7 (or virtual channel 10.5 via PSIP). Previously, the affiliation was seen on WILX-DT3.
In November 2002, WVTM-TV signed on its digital television signal on UHF channel 52. The station shut down its analog signal, over VHF channel 13, on June 12, 2009, the official date in which full-power television stations in the United States transitioned from analog to digital broadcasts under federal mandate. The station's digital signal relocated from its pre- transition UHF channel 52, which was among the high band UHF channels (52–69) that were removed from broadcasting use as a result of the transition, to its former analog-era VHF channel 13 for post-transition operations. WVTM was one of more than ten television stations around the country that requested for a power increase due to problems with the reception of VHF digital signals in areas within their markets of service following the transition.
WHAM-DT2, branded as CW Rochester (formerly CW WHAM), is the CW-affiliated second digital subchannel of WHAM-TV, broadcasting in high definition on virtual and VHF channel 13.2. It is also available on Spectrum channel 16.

When it comes to electronics then the satellite had an onboard data management system, a radio frequency communication system that operated UHF and VHF bands which communicated voice, telemetry and telecommand data and an attitude control system.
WSPA-TV discontinued regular programming on its analog signal, over VHF channel 7, on June 12, 2009, the official date in which full-power television stations in the United States transitioned from analog to digital broadcasts under federal mandate; it continued to broadcast its analog signal despite the March 2009 tower collapse. The station's digital signal relocated from its pre-transition UHF channel 53, which was among the high band UHF channels (52-69) that were removed from broadcasting use as a result of the transition, to its analog-era VHF channel 7.
A Gonset Communicator for the 6 meter amateur band A 2 meter band Communicator II The Gonset Communicator was a series of vacuum tube VHF AM radio transceivers that were widely sold in the 1950s and early 60s. They were designed by Faust Gonsett and manufactured by the Gonset Division of L. A. Young Spring and Wire Corp. Models were built for amateur radio, aircraft radio and U.S. Civil Defense use. The Gonsets were among the first commercial radios available for the post-World War II amateur bands and helped popularize VHF for amateurs.
The site originally consisted of a pair of wooden telegraph poles (one for the transmitting aerials, one for the receiving aerials) erected on land that is itself about above sea level. The television broadcasts primarily covered the town of Machynlleth and the villages of the upper Dyfi river valley. 625-line colour TV came to the site in the late 1970s. A new self-supporting lattice mast was built to carry the UHF aerials but the original VHF TV and VHF radio services continued to use the site's original wooden poles.
The radiotelephony locator beacon sound made by ELTs and some EPIRBs.All ELTs, all PLBs, and most EPIRBs are required to have a low-power homing signal, that is identical to the original 121.500 MHz VHF beacon signal. However, due to the extremely large number of false alarms that the old beacons generated, the transmit power was greatly reduced, and because the VHF transmitter typically uses the same antenna as the UHF beacon, the radiated signal is further reduced by the inherent inefficiencies of transmitting with an antenna not tuned to the transmitted signal.
Apollo Command/Service Module scimitar antenna The Block II Apollo command and service module carried a pair of elliptical VHF scimitar antennas on the Service Module walls. The antenna's scimitar shape wasn't externally visible, since it had to be covered by a shroud for aerodynamic purposes. The antenna radiated and received signals in an approximately hemispherical pattern, therefore two antennas were necessary to provide full omnidirectional coverage. VHF communication was used for ship-to-ground communication in Earth orbit, and ship-to-ship communication with the Apollo Lunar Module.
Many countries use a variant of system H which is known as System G. System G is similar to system H but the lower (vestigial) side band is 500 kHz narrower. This makes poor use of the 8.0 MHz channels of the UHF bands by merely increasing the width of the guard-band by 500 kHz to 1.15 MHz. The advantage(?) is that the RF spectrum of system G (on UHF) is the same as system B (on VHF), simplifying the band-switching circuitry in VHF/UHF televisions.
From the digital transition date forward, the South Hill transmitter rebroadcasts KXLY ABC 4—both in analog on VHF Channel 11 and as 4.1 (ABC HD) and 4.2 (MyNetworkTV/MeTV) over a VHF channel 9 HD digital translator. In June 2017, KXLY-TV added Channel 22, a 15,000 watt fill-in transmitter atop Krell Ridge on Spokane's South Hill. This new digital signal adds stronger service for Spokane's Downtown, Northside, South Hill and Spokane River Valley antenna household locations. Programming from MeTV was added on September 3, 2012.
At that time, Storer owned VHF stations in Atlanta, Detroit, Cleveland and Toledo in addition to WVUE, and the purchase of WITI would have left the company one VHF station over the FCC ownership limit of the time. As a result, Storer had to either sell off or shut down WVUE in order to comply with the ownership limit. There were no interested buyers, however, so Storer took the station off the air on September 13 of the same year. The license was returned to the FCC on December 18.
WBZ-TV shut down its analog signal, over VHF channel 4, on June 12, 2009, the official date on which full-power television stations in the United States transitioned from analog to digital broadcasts under federal mandate. The station's digital signal continued to broadcast on its pre-transition UHF channel 30. Through the use of PSIP, digital television receivers display the station's virtual channel its former VHF analog channel 4. As part of the SAFER Act, WBZ temporarily kept its analog channel on the air to broadcast information regarding the transition to digital television.
DSC distress alerts, which consist of a preformatted distress message, are used to initiate emergency communications with ships and rescue coordination centers. DSC was intended to eliminate the need for persons on a ship's bridge or on shore to continuously guard radio receivers on voice radio channels, including VHF channel 16 (156.8 MHz) and 2182 kHz now used for distress, safety and calling. A listening watch aboard GMDSS-equipped ships on 2182 kHz ended on February 1, 1999. In May 2002, IMO decided to postpone cessation of a VHF listening watch aboard ships.
WOAI-TV discontinued regular programming on its analog signal, over VHF channel 4, on June 12, 2009, the official date in which full-power television stations in the United States transitioned from analog to digital broadcasts under federal mandate.

In the Republic of Ireland, UHF was introduced in 1978 to augment the existing RTÉ One VHF 625-line transmissions and to provide extra frequencies for the new RTÉ Two channel. The first UHF transmitter site was Cairn Hill in Co. Longford, followed by Three Rock Mountain in South Co. Dublin. These sites were followed by Clermont Carn in Co. Louth and Holywell Hill in Co. Donegal in 1981. Since the analogue television switchoff on October 24, 2012, all digital terrestrial TV is on UHF only, although VHF allocations exist.
The name of the group is provisional. The Japanese documents for the association refer to the acronym JAITS but the fully spelled English name has not been disclosed yet. The group's Japanese name has the term UHF because all of the member stations broadcast on the UHF band in analog, in contrast to major networks that primarily broadcast on the VHF band in analog. All the Japanese terrestrial television stations switched to UHF digital when all analog television transmissions (both VHF and UHF) were shut down between July 24, 2011 and March 31, 2012.
The area around Majar al-Kabir is very flat and as a result, HF and VHF radios do not work well; even within close range, there are dead zones where the signal cannot be accessed. The Paratroopers had PRRs (Personal Role Radios), an Iridium satellite phone and a VHF radio. All the RMP had was a selection of radios in their Land Rovers. An Iraqi elder appealed to the gunmen surrounding the station to stop shooting and he went to go inside and was granted access by LCpl Tom Keys.
WEDU shut down its analog signal, over VHF channel 3, on February 17, 2009, to conclude the federally mandated transition from analog to digital television.Congress delays digital TV switch, but WEDU will switch this month, Eric Deggans, St. Petersburg Times, February 5, 2009List of Digital Full-Power Stations The station moved its digital signal from its pre- transition UHF channel 54. That channel was among the high band UHF channels (52-69) that were removed from broadcast service. On June 12, 2009, it moved to VHF channel 13.
TEN launched Australia's first metropolitan nightly one-hour news bulletin in 1975, while NBN-3 in Newcastle was first to air a one-hour news service in Australia in 1972. In 1978, Katrina Lee became only the third female TV newsreader on Australian TV – the first being Melody Illiffe on QTQ-9. The current anchor for the 10 News First 5pm Sydney news bulletin on weeknights is Sandra Sully. TEN commenced digital television transmission in January 2001, broadcasting on VHF Channel 11 while maintaining analogue transmission on VHF Channel 10.
WOSH-TV gained an affiliation with ABC on December 26, 1953. WOSH-TV faced several issues as 1954 began. UHF tuners, which had already gained a reputation for poor reception and tuning, were not in enough households in the WOSH broadcast area to attract advertisers, and were not a requirement on new television sets, most of which were VHF only. Additionally, as was soon discovered generally, UHF stations did not have the same broadcast characteristics as more established VHF stations; their signals did not travel as far with similar transmission power.
The other two experiments will study the Earth's ionosphere. SmartMESA, the Smart Miniaturized Electrostatic Analyzer, was designed to record the ion density of the ionosphere, as well as the temperature, to allow a study of how temperature affects ion density. It is a reflight of the original SmartMESA mission, which was lost when FalconSat-2 failed to achieve orbit. The Receiver UHF/VHF Signal Strength, or RUSS, experiment, is intended to receive radio signals in the UHF and VHF bands, to determine the levels and effects of ionospheric interference.
Airband or aircraft band is the name for a group of frequencies in the VHF radio spectrum allocated to radio communication in civil aviation, sometimes also referred to as VHF, or phonetically as "Victor". Different sections of the band are used for radionavigational aids and air traffic control.H. P. Westman (ed), Reference Data for Radio Engineers Fifth Edition, Howard W. Sams and Co, 1968, page 1-6 In most countries a license to operate airband equipment is required and the operator is tested on competency in procedures, language and the use of the phonetic alphabet.
"Rabbit-ears" VHF television antenna (the small loop is a separate UHF antenna). One of the most common applications of the dipole antenna is the rabbit ears or bunny ears television antenna, found atop broadcast television receivers. It is used to receive the VHF terrestrial television bands, consisting in the US of 54 to 88 MHz (band I) and 174 to 216 MHz (band III), with wavelengths of 5.5 to 1.4 m. Since this frequency range is much wider than a single fixed dipole antenna can cover, it is made with several degrees of adjustment.
After KOMO-TV (channel 4) signed on in December 1953, Seattle's channel 7 was the last commercial VHF channel allocation available in the Puget Sound area. As such, its construction permit was heavily contested among several local broadcast interests. Three radio stations—KVI (570 AM), KXA (770 AM, now KTTH) and KIRO (710 AM)—were locked in a battle for the frequency over several years of comparative hearings at the Federal Communications Commission (FCC). Following an initial decision in 1955"FCC proposes 3 VHF grants." Broadcasting – Telecasting, April 11, 1955, pg. 96.
Norway has a Short distance radio service (called "KDR444" to distinguish it from similar services such as PMR446) with six UHF FM channels between 444.600 and 444.975 MHz. Some dual-mode KDR/PMR radios are sold but are only usable in Sweden and Norway. Norway has a 6 channel VHF FM Jaktradio (Hunting Radio) service, maximum power 5 watts. Because both Norway and Sweden have high-band VHF FM hunting allocations (see section on Sweden below), many hunting radios are marketed with both the 6 Norse channels and 7 Swedish channels in one unit.
When Martial Law was declared by then-President Ferdinand Marcos, which forced ABS-CBN to shut down under his crony, Roberto Benedicto, DZRI-TV was subsequently shut down in 1972. That became the final year of the station on the original channel 10 frequency. Eight years later, in 1980, VHF channel 10 was given to the newly-launched station DZEA-TV. While the closed network's intellectual unit was taken over by crony-owned Banahaw Broadcasting Corporation, Benedicto moved the station's VHF assignment from channel 10 to the current channel 3.
WISN-TV shut down its analog signal, over VHF channel 12, at 8:30 a.m. on June 12, 2009 (the transition was led by a retrospective on the station's history narrated by former longtime anchor Jerry Taff, followed by a still of digital transition information that remained until noon, when its analog transmitter was permanently shut down). The station's digital signal continued to broadcast on its pre-transition UHF channel 34.CDBS Print Through the use of PSIP, digital television receivers display the station's virtual channel as its former VHF analog channel 12.
WMUM-TV signed on its digital signal on VHF channel 7 in April 2008, which was followed by the discontinuation of regular programs on its analog signal over UHF channel 29. This coincided with the official date in which full-power television stations of the United States transitioned from analog to digital broadcasts under federal mandate, occurring on June 12, 2009. The station's digital signal remained on its pre- transition VHF on channel 7, using PSIP to display the station's virtual channel as its former UHF analog channel 29.
SBS expanded to Brisbane, Adelaide, Newcastle, Wollongong and the Gold Coast in June of that year. On 5 January 1986, SBS ceased broadcasting on the VHF channel 0 frequency. Although many Australians at the time did not have UHF antennas, SBS's VHF licence had already been extended by a year at this stage and not all antennas had worked well with the low-frequency Channel 0 either.The History of Australian Television: SBS Television , accessed 22 May 2007 In August 1986, the government proposed legislation that would merge SBS into the ABC.
The above frequency bands cover a 15:1 wavelength ratio, or almost 4 octaves. It is difficult to design a single antenna to receive such a wide wavelength range, and there is an octave gap from 216 to 470 MHz between the VHF and UHF frequencies. So traditionally separate antennas (or on outdoor antennas separate sets of elements on a single support boom) have been used to receive the VHF and UHF channels. Starting in 2006 many countries in the world switched from broadcasting using an older analog television standard to newer digital television (DTV).
An original construction permit to build a television station on VHF channel 6 in Kingman granted to Grand Canyon Television Co. on April 8, 1985. Its transmitter facilities were to be located at Hualapai Peak, operating at an effective radiated power (ERP) of 10 kW. The permit was modified in August 1986 to specify Black Mountain as the transmitter location with an ERP of 100 kW, which was the maximum allowed for a low-band VHF station. The station first signed on the air on February 22, 1988, and was licensed on June 1.
WILX-TV shut down its analog signal, over VHF channel 10, on February 17, 2009, the original target date in which full-power television stations in the United States were to transition from analog to digital broadcasts under federal mandate (which was later pushed back to June 12, 2009). The station's digital signal relocated from its pre-transition UHF channel 57, which was among the high band UHF channels (52-69) that were removed from broadcasting use as a result of the transition, to its analog-era VHF channel 10.
KWTX-TV shut down its analog signal, over VHF channel 10, on February 17, 2009, the original target date in which full-power television stations in the United States were to transition from analog to digital broadcasts under federal mandate (which was later pushed back to June 12, 2009). The station's digital signal relocated from its pre-transition UHF channel 53, which was among the high band UHF channels (52–69) that were removed from broadcasting use as a result of the transition, to its analog-era VHF channel 10 for post-transition operations.
However, only two VHF licenses were assigned to the city—channels 6 and 10, occupied by CBS affiliate WLNS and NBC affiliate WILX-TV. UHF was not considered viable even after the FCC mandated all-channel tuning in 1964. Although Lansing is a fairly compact market geographically, it is sandwiched between Detroit to the east, Flint/Saginaw/Bay City to the north, Toledo to the south, and Grand Rapids/Kalamazoo/Battle Creek to the west. Therefore, it was not likely there would have been room to drop in a third VHF allocation.
WPVI-TV signed on its digital signal on November 1, 1998. The station shut down its analog signal, over VHF channel 6, on June 12, 2009, the official date in which full-power television stations in the United States transitioned from analog to digital broadcasts under federal mandate. The station's digital signal relocated from its pre-transition UHF channel 64, which was among the high band UHF channels (52-69) that were removed from broadcasting use as a result of the transition, to its analog-era VHF channel 6 for post-transition operations.
See RKO General, Inc. v. FCC (1981)—I. Procedural History ; "Court Backs RKO On WOR License," New York Times, March 8, 1984 (available online). RKO, however, was about to get a partial, and temporary, reprieve. Congress passed a law, sponsored by New Jersey senator Bill Bradley, requiring the commission to automatically renew the license of any commercial VHF television station relocating to a state without one, “notwithstanding any other provision of law.” The only states qualifying at the time were Delaware and New Jersey, where no commercial VHF outlet had been licensed since 1962.
BBC Radio Brighton was one of the first wave of BBC Local Radio stations which took to the air during the late 1960s. Broadcasting from Marlborough Place, it officially opened on 14 February 1968, though a short- lived emergency service had been broadcast during the blizzards earlier that winter. Originally broadcast on 88.1 MHz VHF only, the station later acquired a medium wave frequency of 202m, and transferred to 95.3 MHz on VHF. The transmission area was initially restricted to little more than the immediate Brighton and Hove conurbation, with the surrounding suburbs.

There are specific operating awards, contests, clubs, and conventions devoted to QRP enthusiasts. In the United States, the November Sweepstakes, June and September VHF QSO Parties, January VHF Sweepstakes, and the ARRL International DX Contest, as well as many major international contests have designated special QRP categories. For example, during the annual ARRL's Field Day contest, making a QSO (ham-to-ham contact) using "QRP battery power" is worth five times as many points as a contact made by conventional means. The QRP ARCI club sponsors 12 contests during the year specifically for QRP operators.
On August 20, 1945, the KRLD Radio Corp. – a subsidiary of the now-defunct Dallas Times Herald newspaper, which was headed at the time by Times Herald Printing Co. president Tom C. Gooch – filed an application with the Federal Communications Commission (FCC) for a license and construction permit to operate a commercial television station on VHF channel 2. On August 22, 1946, one year and two days after it filed for the broadcast license, KRLD Radio Corp. amended its application to instead seek assignment on VHF channel 4.
Tower approval was still pending when it was announced on April 19, 1956, that the construction permit would be bought by then-UHF station KPTV (channel 27) at Portland to allow it to move to VHF. Storer Broadcasting, owner of KPTV, then announced plans to apply to move channel 3 to Portland, a move that would be contested by the three existing VHF stations there. In response, Carl H. Fisher, owner of the Fisher Broadcasting group and owner of broadcast stations in Oregon and Washington, announced plans to file for a new permit.
WMVS' digital signal was previously carried on digital channel 35, which is the designated digital channel of WMVT, due to interference issues with the analog channel 8 signal of WOOD-TV in Grand Rapids until a channel realignment on September 1, 2008. WMVS shut down its analog signal, over VHF channel 10, at 9 a.m. on June 12, 2009, the official date in which full-power television stations in the United States transitioned from analog to digital broadcasts under federal mandate. The station's digital signal continued to broadcasts on its pre- transition VHF channel 8.
WJAR discontinued regular programming on its analog signal, over VHF channel 10, on February 17, 2009, the original date in which full-power television stations in the United States were to transition from analog to digital broadcasts under federal mandate (which was later pushed back to June 12, 2009). The station's digital signal remained on its pre- transition UHF channel 51, using PSIP to display the station's virtual channel as its former VHF analog channel 10. This allowed ShopNBC station WWDP to begin operation of its permanent digital facility on channel 10.
WHTM-TV signed on its digital signal on VHF channel 10 in 1999. The station discontinued regular programming on its analog signal, over UHF channel 27, on June 12, 2009, as part of the federally mandated transition from analog to digital television.List of Digital Full- Power Stations The station's digital signal remained on its pre-transition VHF channel 10,CDBS Print (this forced NBC owned-and-operated station WCAU in Philadelphia to continue broadcasting its digital signal on channel 34), using PSIP to display WHTM-TV's virtual channel as 27 on digital television receivers.
Amateur radio operators who specialize in making two way radio contact with other amateurs in distant countries are also referred to as "DXers". On the HF (also known as shortwave) amateur bands, DX stations are those in foreign countries. On the VHF/UHF amateur bands, DX stations can be within the same country or continent, since making a long-distance VHF contact, without the help of a satellite, can be very difficult. DXers collect QSL cards as proof of contact and can earn special certificates and awards from amateur radio organizations.
WGVU-TV, virtual channel 35 (VHF digital channel 11), is a Public Broadcasting Service (PBS) member television station licensed to Grand Rapids, Michigan, United States.

WGVU's transmitter is located near the GVSU main campus in Allendale, while WGVK's transmitter is based in Kalamazoo's Westwood neighborhood.
One receiver would usually be a R-4A homing receiver, another the VHF R-28/ARC-5, and the last an MF/HF communication receiver. The transmitter rack would hold a VHF T-23/ARC-5 and an MF/HF transmitter corresponding to the MF/HF receiver. Frequency-stabilized versions of the AN/ARC-5 communications receivers usually have a yellow circle-S stamped on the front panel. Such receivers were not remotely tuned by the pilot, but were instead lock-tuned to the associated transmitter's frequency before take-off.

The origin of Larkspur was a post-war project to move tactical short-range radio communications in the forward battle area from HF using amplitude modulation to low-band VHF using frequency modulation. This followed the similar move by the US Army in the latter part of WWII which had demonstrated significant advantages. Where the use of VHF was not practical, HF sets using narrow band phase modulation (NBPhM) were developed as the only practical method at the time of obtaining some performance improvement over the use of AM especially at night. The range of sets originally comprised the vehicle VHF sets C42, C45, B45, B47, B48 and the C13 vehicle HF transceiver, all of which were designed to specifications produced by the government Signals Research and Development Establishment (SRDE) at Christchurch and initially designated as the "New Range" to differentiate them from wartime legacy radios.

In 1986, his team developed a process for Very High Frequency Plasma Deposition (VHF plasma). In 1987, Shah took on an additional, subsidiary position as part-time professor of electronic materials at the École Polytechnique Fédérale de Lausanne (EPFL), one of only two Swiss Federal Institutes of Technology. Using VHF plasma technology, his group was able to deposit microcrystalline silicon layers as a new photoactive material for solar cells. By combining a microcrystalline with an amorphous silicon layer, a new type of thin-film tandem solar cell was introduced by Shah's group in 1994, under the name of micromorph solar cell.
The Truskmore television transmitter opened on 1 February 1962, the second of the original five main Telefis Éireann transmitters to go on air after Kippure (December 1961). It used as antenna carrier a 135 metres tall mast. Initially its transmissions were only in 405 lines on VHF channel 11, with 625-lines transmissions beginning in November 1963 on Channel I. The new RTÉ Radio VHF FM radio service was added in 1966. The Second television service came in 1978 on Channel G and UHF television transmission began in 1996 with the advent of Teilifís na Gaeilge.
During this period, the network could also be seen in Naples on low-powered WBSP-LP on VHF channel 9 because this translator repeated WEVU-LP's weak signal to the market's southern locations. The working relationship lasted until midnight on September 1, 2004 shortly after Holston Valley Broadcasting (then owner of over-the-air WEVU-LP) struck a deal for carriage of the station on DirecTV. However, this forced VHF channel 7 to seek UPN programming via microwave from UPN owned-and-operated station WTOG in St. Petersburg, Florida. Eventually, Comcast merged with MediaOne and took over as the area's cable provider.
On the antenna pole were installed UHF TV antenna system, VHF TV antenna system and VHF FM antenna system which broadcast analog radio and television signal.

KAIT first signed on July 15, 1963 as an independent station, a venture of Fort Smith businessman George Hernreich. It has been affiliated with ABC since 1965. Most television markets in the country received at least two VHF commercial channels. However, the Jonesboro market could only receive one VHF license because it was sandwiched between Springfield (channels 3 and 10) to the west, Memphis (channels 3, 5, 10, and 13) to the east, Cape Girardeau (channels 3, 6, 8, and 12) to the north, and Little Rock (channels 2, 4, 7, and 11) to the south.
KZTC-LP, VHF analog channel 7, is a low-powered AMGTV-affiliated television station licensed to San Diego, California, United States. KZTC-LP transmits from Mount Woodson, northeast of Poway, and serves mainly the northwest portion of coastal San Diego County. Its signal can also be seen in other parts of east county San Diego, albeit with some interference. When the station is on the air with its VHF signal on channel 7, it blocks Los Angeles' ABC-owned KABC-TV, which has a digital signal on channel 7 which can be received when KZTC is off the air for whatever reason.
WDAF-TV's digital signal was upgraded to full-power high definition on September 23, 2005, increasing its HD signal strength from 1.2 kW to 1000 kW. The station shut down its analog signal, over VHF channel 4, on June 12, 2009, the official date in which full-power television stations in the United States transitioned from analog to digital broadcasts under federal mandate. WDAF continued to transmit its digital signal on its pre-transition UHF channel 34. Through the use of PSIP, digital television receivers display the station's virtual channel as its former VHF analog channel 4.
Born in Washington, D.C., of Belarusian ancestry, Berkofsky began giving public performances from a young age. Later studies were with the Polish pianist Mieczysław Munz, with Konrad Wolff, and Walter Hautzig, as well as with Hans Kann in Vienna. He was active on VHF in the suburban Maryland area during his high school years, and in his later years, he was an amateur radio operator and assembled a VHF/UHF station on his property in Virginia. Some of Berkofsky's earliest professional engagements were as a member of New York's Long Island Chamber Ensemble, of which he was pianist for three years.
Very small UHF TV transmitters continue to operate with no programming or commercial identity, instead retransmitting signals of existing full-power stations to a smaller area poorly covered by the main VHF signal. Such transmitters are called "translators" rather than "stations". The smallest, owned by local municipal-level groups or the originating TV stations, are numbered sequentially – W or K, followed by the channel number, followed by two sequentially issued letters, yielding a "translator callsign" in a generic format that appears K14AA through W69ZZ. Translators and repeaters also exist on VHF channels, but infrequently and with stringently limited power.
Another effect due to the shorter wavelength is that UHF signals can pass through smaller openings than VHF. These openings are created by any metal in the area, including lines of nails or screws in the roof and walls, electrical wiring, and the frames of doors and windows. A metal-framed window will present almost no barrier to a UHF signal, while a VHF signal may be attenuated or strongly diffracted. For strong signals, UHF antennas mounted beside the television are relatively useful, and medium- distance signals, , can often be picked up by attic mounted antennas.
WMAZ-TV is the fourth-oldest television station in the state of Georgia and the oldest outside of Atlanta, beating WDAK-TV (now WTVM) in Columbus to the air by only one day. The Federal Communications Commission (FCC) awarded Southeastern Broadcasting a license to operate a television station on its second try; it had previously made an unsuccessful bid for the VHF channel 7 allocation one year earlier in 1952. The new station was one of the most powerful VHF stations in the country, providing at least secondary signal coverage from the southern Atlanta suburbs to the western suburbs of Savannah.

To preserve bandwidth for the "MyFox10" subchannel on 10.2, the live feed of "Storm Team 10 Fury Radar" was removed for the second time on August 31, 2011.
KHQ-TV discontinued regular programming on its analog signal, over VHF channel 6, on February 17, 2009, the original target date in which full-power television stations in the United States were to transition from analog to digital broadcasts under federal mandate (which was later pushed back to June 12, 2009). The station's digital signal remained on its pre-transition UHF channel 15 due to adjacent channel interference with KSPS (now on channel 8).CDBS Print Through the use of PSIP, digital television receivers display the station's virtual channel as its former VHF analog channel 6.
Since there were four networks but only three VHF stations in most major U.S. cities, one network would be forced to broadcast on a UHF outlet with a limited audience. NBC and CBS had been the larger networks, and the most successful broadcasters in radio. As they began bringing their popular radio programs and stars into the television medium, they sought – and attracted – the most profitable VHF television stations. In many areas, ABC and DuMont were left with undesirable UHF stations, or were forced to affiliate with NBC or CBS stations on a part- time basis.
KVIE shut down its analog signal, over VHF channel 6, on June 12, 2009, as part of the federally mandated transition from analog to digital television.List of Digital Full-Power Stations The station's digital signal relocated from its pre-transition UHF channel 53, which was among the high band UHF channels (52-69) that were removed from broadcasting use as a result of the transition, to VHF channel 9, using PSIP to display KVIE's virtual channel as 6 on digital television receivers. Prior to the transition, the audio feed of KVIE was audible at 87.7 FM in Sacramento and surrounding areas.
Citizens Band radio is a family of services available in different countries and with different operating rules, generally using channels in the 27 MHz part of the radio spectrum. 26–27 MHz occupies the "boundary area" between HF (3–30 MHz) and VHF (30–300 MHz). This means that CB signals provide local coverage similar to low-band VHF during times of low sunspot activity. However, during the peak of the sunspot cycle, CB frequencies exhibit skywave propagation just like the lower parts of HF do, making communication hundreds or even thousands of miles (km) away possible.
KMOV shut down its analog signal, over VHF channel 4, on June 12, 2009, the official date in which full- power television stations in the United States transitioned from analog to digital broadcasts under federal mandate. The station's digital signal remained on its pre-transition UHF channel 24 (which was previously used for the analog signal of KNLC).Digital Television Transition Problematic For Some, Don Corrigan, Webster-Kirkwood Times, January 23, 2009 indicates both KMOV and KNLC as digital-only Through the use of PSIP, digital television receivers continues to display the station's virtual channel as its former VHF analog channel 4.1.
Additionally, several portions of San Diego County are very mountainous, and UHF signals do not carry very well across rugged terrain. Complicating matters, the Mexican authorities had allocated two VHF channels to neighboring Tijuana – channels 6 and 12. Since these were the last two VHF channels left in the area, the FCC did not accept any new construction permits from San Diego as a courtesy to Mexican authorities. One of the frequencies, channel 6, had originally been assigned to San Diego before the freeze; it was reassigned to Mexico as a result of the Sixth Report and Order.
WDSU shut down its analog signal, over VHF channel 6, on June 12, 2009, the official date in which full-power television stations in the United States transitioned from analog to digital broadcasts under federal mandate. The station's digital signal continued to broadcast on its pre- transition UHF channel 43. Through the use of PSIP, digital television receivers display the station's virtual channel as its former VHF analog channel 6. Like all stations broadcasting on channel 6 prior to the digital switchover, WDSU's audio signal could be heard on 87.75 MHz on the FM band in New Orleans and the surrounding areas.
At the start of World War II divisional headquarters were equipped with transmitter-receivers as a back-up to the telephone system. This was used in 1941 when the telephone system in Liverpool was put out of action by bombing, Lancashire Constabulary's radio system was sole means of communications with the city for a time. After the war they were involved in the development and move to VHF FM by the UK police. In 1961 a personal radio scheme was installed in Chorley with Motorola VHF personal radios imported from the USA after a demonstration in Stretford in 1959.
Similar situations occurred in two other Southern markets that were "intermixed" with one UHF and two VHF channels. At the same time WATU was shut down, the owners of NBC station WRDU-TV (now WRDC) in Durham, North Carolina petitioned the Federal Communications Commission for help in its battle against then-CBS affiliate WTVD, which had been cherry-picking NBC programs for several years."Networks, V's balk at aid for UHF's." Broadcasting, September 21, 1970, pg. 40. In 1971 the FCC ruled that VHF stations in markets with three or more commercial outlets could be affiliated with only one network.
The mast was built in 1953 and its construction was brought forward by the BBC so that people in North East England could watch the Coronation of Queen Elizabeth II live on the 405-line television system VHF then in use in the UK. Test transmissions from a low-power temporary aerial began on Monday, 20 April 1953, and the first programmes were transmitted on Friday, 1 May 1953, in plenty of time for the Coronation on 2 June. UHF transmissions began in 1966 with the first colour transmissions in 1970, and the VHF television signal was switched off in 1985.
WMFD-TV signed on its digital signal on VHF channel 12 in 1998, claiming to be the first independent station in the United States to begin digital television broadcasts. The station shut down its analog signal, over UHF channel 68, on June 16, 2008.. The station's digital signal continued to broadcasts on its pre-transition VHF channel 12. Through the use of PSIP, digital television receivers display the station's virtual channel as its former UHF analog channel 68, which was among the high band UHF channels (52-69) that were removed from broadcasting use as a result of the transition.
The Special Tinsel system became increasingly effective, and by the spring of 1943, the Y service was reporting that more and more of the successes being reported by German night fighters were those operating on the newer VHF bands. On 7 April 1943, Bomber Command asked the Air Ministry for a solution, which emerged as "Cigar". Because VHF transmitters of the required power were large, this was built in a ground-based form. The first example was set up at Sizewell and went into operation for the first time on the night of 30/31 July 1943.
KHII-TV (as KFVE) discontinued regular programming on its analog signal, over VHF channel 5, on January 15, 2009, the date in which full-power television stations in Hawaii transitioned from analog to digital broadcasts (six months earlier than the June 12 transition date for stations on the U.S. mainland). The station's digital signal remained on its pre-transition UHF channel 23, using PSIP to display the station's virtual channel as its former VHF analog channel 5. Following the channel swap with KGMB, the station's digital channel switched to UHF channel 22 and its virtual channel to 9.
The RP38 VHF Hunter was released in 1969, and was intended to be an "economy" set. It had MW, LW and VHF coverage, but with a cheaper combined tuner section (which was more in line with the majority of sets at the time anyway), and a simplified audio amplifier that lacked the separate bass and treble controls of the Heralds and Sovereigns. The cabinet was also cheaper to make and lacked a turntable. Initial models used the same 5" by 8" Goodmans loudspeaker as the contemporary RP35 Herald/RP25 Sovereign, but a model from Elac quickly replaced this.
The P-18 has served in several conflicts in the Middle East, Europe and Asia. One unusual feature of the P-18 is its counter-stealth capability. Since the radar uses metre-length wave VHF, the shaping features and radar absorbent materials used on stealth aircraft are less efficient, allowing VHF based radars to detect targets at a greater range than centimeter or millimeter wave radar which stealth aircraft are optimized against. The presence of a P-18 radar in Yugoslavia during the Kosovo War is believed to have contributed to the loss of a US F-117 Nighthawk during the conflict.
Until the squadron was completely re-equipped with new aircraft using only centimetric radar, it was necessary to ensure that all fighter aircraft in the air at any one time had either VHF or S-Band equipment – never a mixture. The S-Band equipped Beaufighters were unable to make use of the VHF Radar Beacons.Pers.Corr. with Squadron Leader Mike Dean, MBE, of the Historical Radar Archive. The changeover was not completed until August 1943, just prior to the squadron's departure to Sicily. On the 21st, seven aircrews relocated to Bône in readiness for intruder operations over Sardinia.
WKMG-TV shut down its analog signal, on VHF channel 6, on June 12, 2009, as part of the federally mandated transition from analog to digital television. The station's digital signal remained on its pre-transition UHF channel 26. Through the use of PSIP, digital television receivers continues to display the station's virtual channel as its former VHF analog channel 6.1. WKMG's audio signal was formerly available at 87.75 MHz on the FM band in Orlando, Daytona Beach and surrounding areas, though at a slightly lower volume than FM radio stations due to TV modulation standards.
WPTZ shut down its analog signal, over VHF channel 5, on February 17, 2009, the original date in which full-power television stations in the United States were to transition from analog to digital broadcasts under federal mandate (which was later pushed back to June 12, 2009). The station's digital signal remained on its pre-transition UHF channel 14. Through the use of PSIP, digital television receivers display the station's virtual channel as its former VHF analog channel 5. It was one of the first stations owned by Hearst to cease analog broadcasting (KITV in Honolulu, Hawaii was the other).
Local television stations in the United States were concentrated on the VHF dial (channels 2–13) in the early days of the industry. However, it soon became apparent that the twelve channels available on the VHF dial would not be sufficient to meet the demands of the growing industry. As a result, in 1952, the FCC opened up a new spectrum of frequencies on the UHF dial (channels 14–83) for terrestrial television. As an incentive for companies to operate UHF stations, the FCC relaxed the ownership limit for a given entity from five to seven stations, provided that no more than five were on the VHF dial. With this opportunity to expand its roster of O&Os;, NBC bought WBUF-TV (channel 17) in Buffalo in 1955 and WKNB-TV (channel 30) in New Britain, Connecticut (near Hartford) in 1957, and changed WKNB's call letters to WNBC-TV (the present-day WNBC in New York City used the WRCA-TV callsign from 1954 to 1960).
From 1990 to 1995, the goal of the SpeakEasy program was to demonstrate a radio for the U.S. Air Force tactical ground air control party that could operate from 2 MHz to 2 GHz, and thus could interoperate with ground force radios (frequency-agile VHF, FM, and SINCGARS), Air Force radios (VHF AM), Naval Radios (VHF AM and HF SSB teleprinters) and satellites (microwave QAM). Some particular goals were to provide a new signal format in two weeks from a standing start, and demonstrate a radio into which multiple contractors could plug parts and software. The project was demonstrated at TF-XXI Advanced Warfighting Exercise, and demonstrated all of these goals in a non-production radio. There was some discontent with failure of these early software radios to adequately filter out of band emissions, to employ more than the simplest of interoperable modes of the existing radios, and to lose connectivity or crash unexpectedly.
4 MI. W. OF CAVALIER, ND The station's launch, however, would remain delayed until 1986. During a June 1981 hearing to extend CKND-TV's signal into the Westman area and to hear the application by Western Manitoba Broadcasters Ltd. (Craig) for a new television station at Portage la Prairie, Canwest said that the Westman transmitter on a VHF channel would reach up to 175,000 more viewers than with the CKND-TV Winnipeg signal. The signal would stretch from the US border to Dauphin, and from Central Manitoba to Saskatchewan. At an April 1982 CRTC hearing regarding licensing a new television station for southern Manitoba, Canwest stated that while they were given VHF channel 2 to operate the CKND- TV2 rebroadcaster, they could have used VHF channel 13 instead. Canwest also stated that it would require a population of over 100,000 to serve the Interlake area with two or three UHF transmitters, rather than the 30,000 that existed at the time.
The purpose of the antenna is to intercept radio waves from the desired television stations and convert them to tiny radio frequency alternating currents which are applied to the television's tuner, which extracts the television signal. The antenna is connected to the television with a specialized cable designed to carry radio current, called transmission line. Earlier antennas used a flat cable called 300 ohm Twin Lead. The standard today is 75 ohm coaxial cable, which is less susceptible to interference, which plugs into an F connector or Belling-Lee connector (depending on region) on the back of the TV. In most countries, television broadcasting is allowed in the very high frequency (VHF) band from 47 to 68 MHz, called VHF low band or band I in Europe; 174 to 216 MHz, called VHF high band or band III in Europe, and in the ultra high frequency (UHF) band from 470 to 698 MHz, called band IV and V in Europe.
Field day events have traditionally carried the same general operating and scoring structures as other contests, but the emphasis on emergency readiness and capability has historically outweighed the competitive nature of these events. Modern contests draw upon the heritage of DX communications, traffic handling, and communications readiness. Since 1928, the number and variety of competitive amateur radio operating events have increased. In 1934, contests were sponsored by radio societies in Australia, Canada, Poland, and Spain, and the ARRL sponsored a new contest specifically for the ten meter amateur radio band. By the end of 1937, contests were also being sponsored in Brazil, France, Germany, Great Britain, Hungary, Ireland, and New Zealand. The first VHF contest was the ARRL VHF Sweepstakes held in 1948,Tilton, E.P. W1HDQ (1947). "VHF Sweepstakes, January 17th-18th". QST. Dec., 1947, p. 128. and the first RTTY contest was sponsored by the RTTY Society of Southern California in 1957.

Diplexers are also commonly used where a multi-band antenna is used on a tower, with a common feedline. The diplexer will split the two bands inside the building (such as VHF and UHF systems combined with a diplexer onto a common antenna).
Act III Broadcasting bought the station in 1987. Soon after buying control, Act III applied to move the station to the VHF band. Despite broadcasting from a tower with the maximum five million watts of power, WVAH had considerable difficulty penetrating the market.
New Zealand's FM frequency allocation issue was not fixed until the late 1990s, when the FM band was expanded to the standard full 20 MHz block. As of the mid-2010s NZ totally abandoned its VHF band for UHF channels above 25.
Reflection is observed with many types of electromagnetic wave, besides visible light. Reflection of VHF and higher frequencies is important for radio transmission and for radar. Even hard X-rays and gamma rays can be reflected at shallow angles with special "grazing" mirrors.

The Tube ceased operations on October 1, 2007, citing "financial limitations" as well as due to disagreements between network parent The Tube Media Corp.
Band I is a range of radio frequencies within the very high frequency (VHF) part of the electromagnetic spectrum. The first time there was defined "for simplicity" in Annex 1 of "Final acts of the European Broadcasting Conference in the VHF and UHF bands - Stockholm, 1961". Band I ranges from 47 to 68 MHz for the European Broadcasting Area, and from 54 to 88 MHz for the Americas and it is primarily used for television broadcasting in compliance with ITU Radio Regulations (article 1.38). With the transition to digital TV, most Band I transmitters in Europe, Africa, Asia and Australia have already been switched off.
WRIC-TV shut down its analog signal, over VHF channel 8, on June 12, 2009, the official date in which full- power television stations in the United States transitioned from analog to digital broadcasts under federal mandate.

Through the use of PSIP, digital television receivers continue to display the station's virtual channel as its former VHF analog channel 8.1. As part of the SAFER Act, WRIC-TV kept its analog signal on the air until June 26 to inform viewers of the digital television transition through a loop of public service announcements from the National Association of Broadcasters.
The Brecon transmitting station was originally built by the IBA in 1970 as a relay for VHF 405-line analogue television: one of the last 405-line TV stations to be built in Britain. As built, it consisted of a 46 m guyed lattice mast carrying the aerials at the top. This structure was built about 300 m NW of Slwch Tump Iron Age hill fort on the slopes of a 240 m hill known as "The Slwch" overlooking the town. The VHF television feed was provided off- air from Abergavenny, about 25 km to the southeast - itself an off-air relay of St. Hilary near Cardiff.
The use of 45.75 MHz as an intermediate frequency within television receivers became commonplace after UHF reception became an option in 1953. Channel 1's signal on this frequency (over the air, or on analogue cable) could create interference internally within television sets. Most cable systems use frequencies below 54 MHz (Channel 2) for communication back to the cable provider from cable modems and digital apparatus, so any "Cable 1" channel needs to avoid operation on the original VHF Channel 1 frequencies from the pre-1948 bandplans. As such, "cable 1" is not related to the original 44–50 MHz VHF channel except in name.
WVLT-TV shut down its analog signal, over VHF channel 8, on June 12, 2009, the official date in which full-power television stations in the United States transitioned from analog to digital broadcasts under federal mandate. The station's digital signal remained on its pre-transition UHF channel 30.CDBS Print Through the use of PSIP, digital television receivers display the station's virtual channel as its former VHF analog channel 8. As part of the SAFER Act, WVLT-TV kept its analog signal on the air until June 26 to inform viewers of the digital television transition through a loop of public service announcements from the National Association of Broadcasters.
Under Group W, WPCQ had a marginal signal, a minimal local news presence and a program schedule more typical of an independent station, with a large number of cartoons and second-hand syndicated programming. WPCQ was also a UHF network affiliate competing against two long-established network stations on VHF. It also had to deal with three longer-established NBC affiliates, on VHF channels from nearby cities, that were also available over- the-air in large parts of the Charlotte market. Westinghouse was able to escape Charlotte when it sold WPCQ (now WCNC-TV) to Odyssey Television Partners (later to become Renaissance Broadcasting) in 1985.
Channel 5 was included in the original deal, but was concurrently spun off to the Hearst Corporation, which had purchased fellow ABC affiliate KMBC- TV in Kansas City, Missouri from Metromedia in 1982."Hearst to buy Kansas City VHF for $79 million." Broadcasting, September 14, 1981, pg. 81. That station was sold to allow Metromedia to acquire WCVB (to comply with FCC rules in effect at the time that limited the number of VHF stations owned by a single company to only five), and it is believed that Metromedia gave Hearst a right of first refusal offer if WCVB ever went up for sale again.
According to the NTIA, the Coast Guard is the seventh-biggest user of radio spectrum in the United States. The U.S. Coast Guard maintains a network of VHF radio stations at its shore stations and on cutters and boats, as well as stations of the U.S. Coast Guard Auxiliary. In addition, the Coast Guard maintains a chain of high frequency (HF) and medium frequency (MF) radio stations that provide communications in the Atlantic and Pacific oceans, the Gulf of Mexico, and the Caribbean Sea. Coast Guard VHF Radio stations are currently being upgraded through the Rescue 21 program to meet the US obligations under the Global Maritime Distress Safety System.
The use of a digital subchannel on a full-power television station as a replacement for low-power station greatly increases the available coverage area for its programming. Because of interference issues that stations transmitting on the low VHF band (channels 2 to 6) often experience, some stations broadcasting on these frequencies are relayed on the subchannels of stations that are less prone to interference. An example of this is CBS affiliate WRGB in Albany, New York. While WRGB broadcasts its main digital on VHF channel 6 in high definition, CW-affiliated sister station WCWN relays a standard-definition subchannel feed of WRGB over its digital channel 45.
Channel 62 aired programming (on kinescope) from all networks, but reflecting the association of WISE radio with NBC, it was a primary affiliate of that network. The original studio facilities were on land leased from Asheville- Biltmore College, which received two hours a week in air time for educational programming; the channel 62 transmitter was located on Beaucatcher Mountain. Competition arrived the next year when WLOS-TV, operating on VHF channel 13, started up; the new station assumed the ABC and DuMont affiliations. WISE-TV attempted to get a VHF channel to improve its competitive position, proposing to operate on channel 2 instead of 62.
Around this time, Philadelphia's public television station, WHYY- TV, was looking for a way to boost its coverage. Operating on channel 35, it had difficulty attracting an audience because of the limitations of UHF's reach at the time. Shortly after WVUE went off the air, WHYY-TV's owners, the Metropolitan Philadelphia Educational Radio and Television Corporation, asked the FCC for permission to move to channel 12. There weren't any free VHF allocations in Philadelphia itself, and the channel 12 allocation in Wilmington was the only available VHF allocation on the New Jersey or Delaware sides of the market that could cover Philadelphia with a city-grade signal.
When colour UHF television began in 1969, the nearby BBC owned station at Rosemarkie was chosen over Mounteagle to carry these broadcasts. Both the UHF and VHF services continued in tandem until 1985, when VHF television was discontinued in the UK. At this point, Mounteagle ceased broadcasting television services entirely. In 1982 Mounteagle was chosen as the site of the first commercial radio broadcasts in northern Scotland, with Moray Firth Radio taking to the air on 23 February of that year. In 1996 transmitters for Classic FM were added, and then later in 1997 Mounteagle began broadcasting television services again, when transmitters were installed for the launch of Channel 5.
WSOC-TV shut down its analog signal, over VHF channel 9, on June 12, 2009, the official date in which full-power television stations in the United States transitioned from analog to digital broadcasts under federal mandate. The station's digital signal remained on its pre-transition UHF channel 34, until it moved to channel 19 as part of the digital repack in 2019. With the switch to digital, viewers in several parts of Charlotte itself needed an attic-mounted or roof- mounted antenna to get a clear picture from the station. Through the use of PSIP, digital television receivers display the station's virtual channel as its former VHF analog channel 9.
KWTV-DT began transmitting a digital television signal on UHF channel 39 on December 23, 2003. The station discontinued regular programming on its analog signal, over VHF channel 9, on February 17, 2009, as part of the federally mandated transition from analog to digital television (which Congress had moved the previous month to June 12). The station's digital signal relocated from its pre-transition UHF channel 39 to VHF channel 9. Due to reception issues in parts of central Oklahoma, KWTV was granted permission by the FCC to operate a secondary signal on its former UHF digital channel 39 under special temporary authorization in October 2009, mapped to virtual channel 9.2.
WLNE-TV discontinued regular programming on its analog signal, over VHF channel 6, on February 17, 2009, the original date when full-power television stations in the United States were to transition from analog to digital broadcasts under federal mandate (which was later pushed back to June 12, 2009). The station's digital signal remained on its pre-transition UHF channel 49, using PSIP to display the station's virtual channel as its former VHF analog channel 6. It offered a nightlighting service on its analog signal for 60 days following the shutdown. The station aired a looping DTV education program as well as all of its newscasts.
WSAZ-TV discontinued regular programming on its analog signal, over VHF channel 3, on February 17, 2009, the original target date in which full-power television stations in the United States were to transition from analog to digital broadcasts under federal mandate (which was later pushed back to June 12, 2009). The station's digital signal remained on its pre-transition UHF channel 23.Digital Television Information Through the use of PSIP, digital television receivers display the station's virtual channel as its former VHF analog channel 3. Charleston translator W16CE was awarded a construction permit for a new digital signal on channel 27 on August 16, 2018.
Almost all prefectures had at least one privately owned VHF television station (except for Saga). The independent stations broadcast in analogue UHF, unlike major networks, which were historically broadcast primarily in analogue VHF. The loose coalition of UHF independents is operated mostly by local governments or metropolitan newspapers with less outside control. Compared with major network stations, Japan's UHF independents have more restrictive programming acquisition budgets and lower average ratings; they are also more likely to broadcast single episode or short-series UHF anime (many of which serve to promote DVD's or other product tie-ins) and brokered programming such as religion and infomercials.
Bandwidth for television in the United States was allocated by the Federal Communications Commission (FCC) in 1937, solely in the VHF (Very High Frequency) band, across 18 channels. American television broadcasting began experimentally in the 1930s with regular commercial broadcasting in cities such as New York and Chicago in 1941. Efforts at TV broadcasting on any channel were drastically curtailed once World War II began, due largely to lack of available receivers. The upper five VHF channels were removed from the FCC allocation list during the war with those frequencies re-allocated for military use, leaving thirteen channels (1 through 13) as of May 1945.
During this transition, television receivers in the UK had to handle both the VHF and UHF wavebands, which added to the cost of producing the sets. The price of a dual-standard set, combined with the limited coverage of BBC2 and the highbrow programming on that channel, meant that initial sales of dual- standard sets were slow. The VHF system was finally switched off in the UK on 3 January 1985. PAL colour test signals began in 1966 and scheduled transmissions commenced on BBC2 on 1 July 1967, with a full colour service beginning on that channel on 2 December 1967. BBC1 and ITV followed suit on 15 November 1969.
Like other stations in the area, WBRE was forced to rely on repeaters to serve its coverage area for most of its history. The market is one of the largest (in land area) east of the Mississippi River and is very mountainous. In addition, Scranton/Wilkes-Barre was a "UHF island" before the digital transition because it is too close to Philadelphia and New York City for VHF analog service. During March 2010, in a cost-cutting move, all owned and operated translators were shut down after Nexstar determined that its VHF signal for WBRE is adequate enough to reach most of the market.
However, WJJY struggled almost from the start. For one thing, most of its viewers in the Quincy market, a previously all-VHF area, had probably not bought new sets since the Federal Communications Commission required television sets to include UHF tuning capability in 1964. In addition, most Quincy-area viewers could watch ABC on two longer- established VHF stations: KTVI in St. Louis (now a Fox affiliate) and KTVO in Kirksville, Missouri (which became a primary ABC affiliate in 1968). KTVI's grade B signal covers much of the Missouri and Illinois portions of the market, while KTVO's grade B signal covers nearly all of the market.
AIS is intended, primarily, to allow ships to view marine traffic in their area and to be seen by that traffic. This requires a dedicated VHF AIS transceiver that allows local traffic to be viewed on an AIS enabled chartplotter or computer monitor while transmitting information about the ship itself to other AIS receivers. Port authorities or other shore-based facilities may be equipped with receivers only, so that they can view the local traffic without the need to transmit their own location. All AIS transceivers equipped traffic can be viewed this way very reliably but is limited to the VHF range, about 10–20 nautical miles.
KTVK shut down its analog signal, over VHF channel 3, on June 12, 2009, the official date in which full-power television stations in the United States transitioned from analog to digital broadcasts under federal mandate. The station's digital signal continued to broadcast on its pre- transition UHF channel 24. Through the use of PSIP, digital television receivers display the station's virtual channel as its former VHF analog channel 3. As part of the SAFER Act, KTVK kept its analog signal on the air to inform viewers of the digital television transition through a loop of public service announcements from the National Association of Broadcasters.
This allows the study of the interaction of the solar wind with the atmosphere, such as in aurora borealis and other space weather phenomena. In addition to near-space imaging, the use of KAIRA has been demonstrated for long-baseline interferometry observations of pulsars. It operates as either a stand-alone passive receiver, as a receiver for the EISCAT VHF incoherent scatter radar (a conventional dish-type emitter) located at Ramfjordmoen, near Tromsø, Norway, or for use in conjunction with other regional VHF experiments. The site is also a pathfinder for the EISCAT_3D system, a planned network of KAIRA-like phased array systems for three-dimensional imaging.
Telecom Tower, a broadcasting facility atop Black Mountain opened on 15 May 1980 and quickly became a major Canberra landmark. A vital link for television and telephone connections between Sydney and Melbourne, the tower also became the transmission site for CTC's primary VHF 7 signal alongside ABC on VHF 3 and ABC FM 101.9. CTC's original studio building was demolished to make way for the tower and the station produced a 12-minute film on the construction of Telecom Tower which was shown at the visitor's centre. No sooner had Telecom Tower opened, work commenced on Canberra's other most prominent landmark – a new Parliament House.
Radio Aire's original logo Radio Aire logo used from 2004 to 2015. Radio Aire's studios, shared with Greatest Hits West Yorkshire in Burley, Leeds The station was launched at 6am on 1 September 1981 by breakfast presenter Graham Thornton - the first song played on air was Pilot of the Airwaves by Charlie Dore. Radio Aire originally broadcast on 362 metres medium wave (828 kHz AM) and 94.6 VHF but was moved to 96.3 FM (VHF) in 1986. Radio Aire's studios were based on Burley Road, overlooking Kirkstall Road next to ITV Yorkshire's headquarters - it was the first Independent Local Radio station to have purpose-built studios.
Amateur radio contests on VHF and UHF are often scored based on the distance of contacts, typically 1 point per kilometre, so there is a need for amateurs to exchange their locations over the air. To facilitate this, following the growth of the sport in the 1950s, the German QRA locator system was adopted in 1959. The QRA locator system was limited to describing European coordinates, by the mid-1970s there was growing need for a global locator system. By the time of their April 1980 meeting, in Maidenhead, England, the VHF Working Group had received twenty different proposals to replace the QRA locator grid.
In 1970, locomotives DA 1400-04 and 1406 were withdrawn from mainline duties and reassigned as heavy shunters to work in the new Te Rapa hump yard. They received additional low speed controls to assist in these operations, special in-cab Signals to incidate "faster", "slower", "maintain power" and "stop" for drivers linked back to the grid control tower by VHF radio, and a separate VHF radio channel for voice communication to the control tower. The locomotives were reclassified as the DAA class. These locomotives were identifiable by their yellow hood stripes, which were treated so to denote them as being used in special service apart from the DA class.
This mounting provided a ground plane or reflector (provided by the vehicle) for an effective vertical radiation pattern. These popular designs are still in common use and the ‘constant turn’ design originating in Australia have been universally adapted as standard FM receiving antennas for many factory produced motor vehicles as well as the existing basic style of aftermarket HF and VHF mobile helical. Another common use for broadside helixes is in the "rubber ducky antenna" found on most portable VHF and UHF radios using a steel or copper conductor as the radiating element and usually terminated to a BNC / TNC style or screw on connector for quick removal.

Viral hemorrhagic fevers (VHFs) are a diverse group of animal and human illnesses in which fever and hemorrhage are caused by a viral infection. VHFs may be caused by five distinct families of RNA viruses: the families Filoviridae, Flaviviridae, Rhabdoviridae, and several member families of the Bunyavirales order such as Arenaviridae, and Hantaviridae. All types of VHF are characterized by fever and bleeding disorders and all can progress to high fever, shock and death in many cases. Some of the VHF agents cause relatively mild illnesses, such as the Scandinavian nephropathia epidemica (a hantavirus), while others, such as Ebola virus, can cause severe, life- threatening disease.
WSET-TV discontinued regular programming on its analog signal, over VHF channel 13, on June 12, 2009, the official date in which full-power television stations in the United States transitioned from analog to digital broadcasts under federal mandate. In October 2009, the station's digital signal relocated from its pre-transition UHF channel 34 to VHF channel 13. The station's over-the-air coverage in much of the western part of the market, especially the New River Valley, is somewhat marginal due in part to the mountainous terrain. W05AA was converted to digital operation in late 2009, which helped to fill in coverage holes in Roanoke.
In May 2006, the FCC opened a brief application period in which low-power television licensees and permittees could apply for a digital companion channel by short- form application. KCOS-LP applied for VHF channel 13, to broadcast from the same location as the analog station. In September, the FCC identified the station as a singleton applicant, meaning that there were no competing applications on the same or adjacent channels, and giving the station until October 31 to file a long-form application. On October 2, 2006, KCOS-LP formally applied for a digital companion channel on VHF channel 13, but no construction permit was granted.
WHAS-TV discontinued regular programming on its analog signal, over VHF channel 11, on June 12, 2009, the official date in which full-power television stations in the United States transitioned from analog to digital broadcasts under federal mandate. The station's digital signal relocated from its pre-transition UHF channel 55, which was among the high band UHF channels (52–69) that were removed from broadcasting use as a result of the transition, to its analog-era VHF channel 11. Like most ABC stations that were formerly owned by Belo, WHAS-TV's main channel is transmitted in the 1080i high definition resolution format rather than ABC's default 720p format.
JOHX-TV was originally established as an affiliate of Nippon News Network (NNN) and Nippon Television Network System (NNS) in Yahata (Yahata Higashi-ku, Kitakyūshū) in August 1958, airing on VHF channel 9; a station in Fukuoka was established in February 1962 as JOJY-TV. They changed affiliation from NNN and NNS to FNN and FNS in October 1964. The head office was moved to Fukuoka, and the call sign changed from "JOHX-TV" (still the call sign of Kitakyūshū satellite station (airing on VHF channel 10)) to "JOJY-TV" in December 1974. They relocated their office to its current location near Fukuoka Tower in August 1996.
In broadcast law (particularly within U.S. law), the pervasiveness doctrine is the doctrine that because broadcast radio waves are available to anyone and therefore "uniquely pervasive", their content is subject to regulation. In general, profanity and sex, or other adult material deemed "indecent" by a broadcasting authority, may not be broadcast outside of overnight "watershed" or "safe harbor" hours when children are unlikely to be awake. Material deemed "obscene" may still be prohibited at all times. This has generally been held to only apply to the AM broadcast band (mediumwave), FM broadcast band (VHF band II), and TV broadcast bands (VHF band I and band III, and UHF).
KFDX-TV signed on a digital signal on UHF channel 28 in 2003; the station began broadcasting NBC network programming in high definition in 2009, when KFDX upgraded its main digital feed to the 1080i resolution format.

WBKP, virtual and VHF digital channel 5, is a CW+-affiliated television station licensed to Calumet, Michigan, United States, serving the Central and Western Upper Peninsula of Michigan. The station is owned by the Marks Radio Group, as part of a duopoly with Ishpeming-licensed ABC affiliate WBUP (channel 10). The two stations share studios on Ash Street in Ishpeming Township; WBKP's transmitter is located on Tolonen Hill near unincorporated Painesdale in Adams Township. Since WBKP cannot be seen over the air in Marquette, it is simulcast in standard definition on WBUP's second digital subchannel (virtual and VHF channel 10.2) from a transmitter south of Ely Township in unincorporated Marquette County.
WUVM-LP, VHF analog channel 4 (VHF digital 2), is a low-powered Azteca América-affiliated television station licensed to Atlanta, Georgia, United States. On Cable, this station is available only in standard definition on Charter Spectrum channel 210, and Comcast Xfinity channel 15 (formerly shown on channel 249). It is one of the few LPTV stations in the country to be seen on satellite TV (since must-carry does not apply to them), as it is part of DirecTV's local lineup. The city of license is Atlanta, but the very directional antenna is aimed northwest and west from the North Druid Hills area, also covering most of Cobb County.
On January 30, 2004, the Canadian Radio-television and Telecommunications Commission (CRTC) granted CBLT permission to broadcast a digital signal on UHF channel 20; CBLT's began broadcasting programming in high definition on March 5, 2005.

WOFL, along with KVVU in Las Vegas, were excluded from the 1994 affiliation deal between Meredith and CBS, which was spurred by an affiliation deal between Fox and New World Communications that caused Tampa-based WTVT and 11 other stations to switch to the network. The two stations were among Fox's strongest affiliates at the time, despite WOFL broadcasting on the UHF band and wtvt broadcasting on the VHF band. At the same time, CBS's existing Orlando station, WCPX-TV (channel 6, now WKMG- TV), was one of that network's weaker affiliates, and Fox did not want to move from a UHF outlet to a lower-rated VHF outlet.
CBUT shut down its analogue signal, over VHF channel 2, on August 31, 2011, the official date in which Canadian television stations in CRTC-designated mandatory markets transitioned from analogue to digital broadcasts. The station's digital signal was relocated from its pre-transition UHF channel 58, which was among the high band UHF channels (52–69) that were removed from broadcasting use as a result of the transition, to post-transition channel 43. Through the use of PSIP, digital television receivers display CBUT-DT's virtual channel as its analogue-era VHF channel 2.

KSLN-TV, UHF analog channel 34, was a commercial television station licensed to Salina, Kansas, United States, which broadcast in two separate incarnations on the same license from 1962 to 1965. The station was the ABC television affiliate in Salina throughout its existence, but operating on a UHF channel and with extremely low-power facilities for a full-service TV station, it could not compete effectively with the VHF television stations received in Salina. The station closed in 1965 and began a quest to move a VHF allocation to Salina, which ended in failure when the Federal Communications Commission ruled the proposal technically deficient in 1968.
KOB-TV shut down its analog signal, over VHF channel 4, on June 12, 2009, the official date in which full-power television stations in the United States transitioned from analog to digital broadcasts under federal mandate.

The channel was originally launched as Channel 4 Bang Khum Phron (ช่อง 4 บางขุนพรหม) with test transmissions beginning on 6 September 1954 and beginning formal broadcasts on 24 June 1955. The then new channel operated under the management of the Thai Television Company (founded 1952). The channel began to broadcast daily in 1957. In 1974, the channel migrated from broadcasting in black-and-white at 525-lines on VHF channel 4 to a colour using a 625-line system on VHF channel 9 (the second in Southeast Asia). On 3 February 1977, the Thai Television Company was dissolved and channel 9 was put under direct State administration.
The Moel-y-Parc transmitting station is situated on Moel y Parc, a hill in north-east Wales at the northern end of the Clwydian range, close to the town of Caerwys and several miles (kilometres) north-east of Denbigh.

System A was the first formal broadcasting standard in the world. A European 41–68 MHz Band I television allocation was agreed at the 1947 ITU (International Telecommunications Union) conference in 1947, effectively "grandfathering in" the VHF allocation that has been used in Britain since 1936.
"TV applications." Broadcasting – Telecasting. June 9, 1952, pg. 73. Following the move to channel 11, the station became to first to increase its effective radiated power to 316,000 watts, the maximum allowed for a high-band VHF station, resulting in a greatly increased signal coverage area.
VHF is also used for line of sight communication such as aircraft-to-aircraft and aircraft-to-ATC. Amplitude modulation (AM) is used, and the conversation is performed in simplex mode. Aircraft communication can also take place using HF (especially for trans-oceanic flights) or satellite communication.
WKNO discontinued regular programming on its analog signal, over VHF channel 10, on May 1, 2009.List of Digital Full-Power Stations The station's digital signal remained on its pre-transition UHF channel 29, using PSIP to display WKNO's virtual channel as 10 on digital television receivers.
WSMV-DT4 is the Court TV-affiliated fourth digital subchannel of WSMV-TV, broadcasting in 16:9 widescreen standard definition on VHF channel 10.4 (or virtual channel 4.4 via PSIP). On May 9, 2019, WSMV signed on a fourth subchannel to carry the recently relaunched Court TV.
Like other lights in Boston Harbor, the automatic fog signal has been replaced by a Mariner Radio Activated Sound Signal (MRASS) which can be activated by nearby mariners by tuning their marine VHF radio to channel 83A (157.17 5Mhz) and keying the transmitter five times consecutively.
The Soviet broadcast television standard used System D (OIRT VHF band with the "R" channels ranging from R1 to R12) and System K (pan-European/African UHF band), with SECAM as the color system standard. The resulting system is commonly referred to as "SECAM D/K".
In Spain, REMER (Red Radio de Emergencia, Emergency Radio Network) is a national HF/VHF network formed by volunteer ham radio operators, and it is co-ordinated by the local Civil defense groups, which are dependent from the local government authority. It was founded on 1982.
WITI shut down its analog signal, over VHF channel 6, on June 12, 2009, the official date in which full-power television stations in the United States transitioned from analog to digital broadcasts under federal mandate. The station's digital signal continued to broadcasts on its pre-transition UHF channel 33. Through the use of PSIP, digital television receivers display the station's virtual channel as its former VHF analog channel 6. As part of the SAFER Act, WITI kept its analog signal on the air until June 25 to inform viewers of the digital television transition through a loop of English and Spanish public service announcements from the National Association of Broadcasters, although this loop was interrupted several times during the period to run severe weather coverage. The digital transition resulted in the loss of ability to listen to WITI's audio feed over 87.7 FM; television stations broadcasting on VHF channel 6 were audible over this frequency during the analog television era, although this is no longer possible due to the transition, even for stations that broadcast their digital signals on channel 6.
Other areas would be designated as "UHF islands" since they were too close to larger cities for VHF service. The "2" networks became CBS and NBC, "+1" represented non-commercial educational stations, and "1/2" became ABC (which was the weakest network usually winding up with the UHF allocation where no VHF was available). However, the Binghamton market was sandwiched between Syracuse (channels 3, 8 (later 5), and 9) and Utica (channel 13, later 2) to the north, Elmira (a UHF island) to the west, Scranton–Wilkes-Barre (a UHF island) to the south, and Albany-Schenectady-Troy (channels 4 (later 6), 10, and later joined by 13) and New York City (channels 2, 4, 5, 7, 9, 11, and 13) to the east. This created a large "doughnut" in south-central New York where there could only be one VHF license. Binghamton was also too close to Lancaster, Pennsylvania, and New Haven, Connecticut to reallocate channel 8 into the market; the original channel 8 allocation would later be moved to Rochester.
Many other large UHF-/VHF- transmitters use diplexers. The number of transmitters which can share an antenna is restricted by the spacing of their frequency bands. Transmitters whose frequencies are too close together cannot be combined successfully by a diplexer. Diplexers are also used at medium wave broadcasting stations.
In many applications, UHF connectors were replaced by designs that have a more uniform surge impedance over the length of the connector, such as the N connector and the BNC connector. UHF connectors are still widely used in amateur radio, Citizens Band radio, and marine VHF radio applications.
The lifeboat was fitted with Decca 060 radar and all she carried Pye Westminster VHF and an Ajax MF radio telephones. In addition a radio Direction Finding set was carried, which gave a magnetic bearing to a transmitting station. The electric searchlight was standard along with Pains Wessex speedlines.
Since 1953, Biedenkopf has been host to a Hessischer Rundfunk VHF and television transmission facility on the Sackpfeife. The antenna are borne by a 210-m guyed steel-lattice mast with a diagonal cross-section measure of 1.8 m. Its position is 50°57'8"N, 8°32'1"E.
Monica was a range-only tail warning radar for bombers, introduced by the RAF in June 1942."Bf 110 vs. Lancaster", Robert Forczyk, Osprey Publishing, 2013, p. 11 Officially known as ARI 5664, it operated at frequencies of around 300 MHz (on the boundary between VHF and UHF).
Hooton 1997, p. 259. The Luftwaffe's introduction of the lower frequency VHF-band Lichtenstein SN-2 airborne radar was an attempt to produce a set invulnerable to jamming. It came into wide usage between autumn 1943 and the beginning of 1944. The methods quickly caused trouble for Bomber Command.

KXDP-LP, VHF analog channel 6, is a low powered Regional Mexican-formatted television station licensed to Denver, Colorado, United States. The station is owned by the Syncom Media Group. Because the station broadcasts an analog signal on channel 6, its audio can be received at 87.75 MHz FM.
A construction permit for channel 2, Portland's last available channel allocation on the VHF band, was issued to Fisher's Blend Station, Inc., (later known as Fisher Communications) in 1958. However, KATU did not begin broadcasting until March 15, 1962, originally operating as an independent station.Murphy, Francis (March 17, 1962).
Light TV is a commercial television network in the Philippines. It formerly used the frequency of VHF 11 in 1998. They moved to UHF 33 in 2005 after GMA Network Inc. and this network had a blocktime agreement, and use the Citynet Television frequency as their repeater station.
QTQ is an Australian television station, licensed to, and serving Brisbane, Queensland. It is owned by the Nine Entertainment Co., and is part of the Nine Network.

This deal came because WKRC-TV's owner, Taft Broadcasting, had developed very good relations with ABC. Following the release of the FCC's Sixth Report and Order in 1952, all of Cincinnati's VHF stations changed channel positions."TV coverage; RTMA predicts expansion." Broadcasting – Telecasting, May 19, 1952, pg. 78.
The core of company started even before the Velvet revolution in 1989 with design and production of equipment for radio amateurs. Radio modems for UHF and VHF licensed bands and wireless data networks became RACOM's main focus shortly afterwards, the first radio modem has been developed in 1991.
KVIE, virtual channel 6 (VHF digital channel 9), is a Public Broadcasting Service (PBS) member television station licensed to Sacramento, California, United States.

Each region of enforcement has people from these sections providing the department with communication support. The Puerto Rico Police radio communications are on VHF, UHF and 800 MHz. The metro area is covered by two Motorola 800 MHz trunked radio systems. The system is Motorola Type II since 1992.
Communication, i.e. aviation communication, refers to radio communication between two or more aircraft, or the exchange of data or verbal information between aircraft and air traffic control. For continental airspace, VHF (civil) and UHF (military) systems are used whereas for oceanic areas, high frequency systems and SATCOMs are used.
Not long after, the DuMont network itself shut down. The station remained on the FCC books until at least 1960. At one point, the licensee held a construction permit for VHF channel 9, according to now defunct website BostonRadio.com. However, the station never signed back on the air.
TRANSRADIO SenderSysteme Berlin AG was a German radio communication systems producer, specialised in research, development and design of AM, VHF/FM and DRM such as military and commercial broadcasting systems. Intermediate they were subsidiary of swiss AMPEGON AG and today affiliate company of CESTRON International GmbH named Elsyscom GmbH.

Amateur radio frequency allocations vary around the world. Several bands are common for amateurs worldwide, usually in the HF part of the spectrum. Other bands are national or regional allocations only due to differing allocations for other services, especially in the VHF and UHF parts of the radio spectrum.
WTSP, virtual and VHF digital channel 10, is a CBS-affiliated television station licensed to St. Petersburg, Florida, United States and also serving Tampa. The station is owned by Tegna Inc.

A helical resonator is a helix of wire in a cavity; one end is unconnected, and the other is bonded to the cavity wall. Although they are superficially similar to lumped inductors, helical resonators are distributed-element components and are used in the VHF and lower UHF bands.
KTXC-LP, UHF analog channel 46 (VHF digital channel 10.2), was a low-powered independent television station serving Amarillo, Texas, United States that was licensed to Canyon. Co-owned KFDA-TV shared its studios in rural Potter County north of Amarillo, while its transmitter was based in Canyon.
In 2002, WBPH applied to have its digital channel assignment reallocated from UHF channel 59 to VHF channel 9. The reason for this was that both the station's analog and digital channels were among the high band UHF channels (52-69) that would be removed from broadcasting use upon the formal transition to digital broadcasts. With the FCC's approval of this application, WBPH became the first station in the Lehigh Valley to broadcast on a VHF channel.North East RadioWatch: July 15, 2002 WBPH shut down its analog signal, over UHF channel 60, on June 12, 2009, the official date in which full-power television stations in the United States transitioned from analog to digital broadcasts under federal mandate.
Sudden changes in the atmosphere's vertical moisture content and temperature profiles can on random occasions make UHF, VHF and microwave signals propagate hundreds of kilometers up to about --and for ducting mode even farther--beyond the normal radio-horizon. The inversion layer is mostly observed over high pressure regions, but there are several tropospheric weather conditions which create these randomly occurring propagation modes. Inversion layer's altitude for non-ducting is typically found between and for ducting about , and the duration of the events are typically from several hours up to several days. Higher frequencies experience the most dramatic increase of signal strengths, while on low-VHF and HF the effect is negligible.
F2 and TE band openings from other ionospheric reflection/refraction modes, or sky-wave propagation as it is known can also occasionally occur on the low band VHF frequencies of 6 or 4 meters, and very rarely on 2 meters (high band VHF) during extreme peaks in the 11 year sunspot cycle. The longest terrestrial contact ever reported on 2 meters (146 MHz) was between a station in Italy and a station in South Africa, a distance of 7784 km, using anomalous enhancement (TE) of the ionosphere over the geomagnetic equator. This enhancement is known as TE, or trans-equatorial propagation and (usually) occurs at latitudes 2500–3000 km within either side of the equator.
VHF (very high frequency) stations started 30 to 35 years later. In the early days, radio stations broadcast on the longwave, mediumwave and shortwave bands, and later on VHF (very high frequency) and UHF (ultra high frequency). However, in the United Kingdom, Hungary, France and some other places, from as early as 1890 there was already a system whereby news, music, live theatre, music hall, fiction readings, religious broadcasts, etc., were available in private homes [and other places] via the conventional telephone line, with subscribers being supplied with a number of special, personalised headsets. In Britain this system was known as Electrophone, and was available as early as 1895 or 1899 [sources vary] and up until 1926.
Examples of a US-made set, the CDS-501, were captured in Cuba and are thought to have seen use in Central and Eastern Europe. The device operated in the upper part of the VHF band and sent high speed bursts of encrypted data from an agent to a receiving station located within a Western diplomatic facility in a hostile country to avoid interception by the adversary signals intelligence service. A high-grade US intelligence source in Cold War Poland, Colonel Ryszard Kukliński, is believed to have been using a SRAC device shortly before his defection to the West in late 1981. Another SRAC device's nomenclature was RT-519, which operated in the VHF spectrum.
The station began providing a digital signal on satellite on November 17, 2003, and on January 30, 2004, CFTO was granted an over-the-air digital television signal, transmitting on UHF channel 40 at an effective radiated power of 17,400 watts. In mid-2005, CFTO upgraded its digital signal to transmit programming in high definition. CFTO shut down its analogue signal, over VHF channel 9, on August 31, 2011, the official date in which Canadian television stations in CRTC-designated mandatory markets transitioned from analogue to digital broadcasts. The station's digital signal was relocated from its pre-transition UHF channel 40 to its analogue-era VHF channel 9 for post-transition operations.
WTVJ ended programming on its analog signal, on VHF channel 6, on June 12, 2009, the official date in which full-power television stations in the United States transitioned from analog to digital broadcasts under federal mandate. The station's digital signal continued to broadcasts on its pre-transition UHF channel 31. Through the use of PSIP, digital television receivers display the station's's virtual channel as its former VHF analog channel 6. After the transition, the station moved its main transmitter from the former WCIX tower site in Homestead to a facility on the Broward–Dade county line, bringing WTVJ's signal on par with the other Miami television stations for the first time in fourteen years.
On July 17, 2008 at 6:15 p.m., KATU conducted a test for viewers to determine whether their television sets were ready for the digital television transition by turning off its analog signal for 10 seconds, which the station conducted other times through the spring of 2009. KATU shut down its analog signal, over VHF channel 2, on June 12, 2009, the official date in which full-power television stations in the United States transitioned from analog to digital broadcasts under federal mandate. The station's digital signal remained on its pre-transition UHF channel 43,CDBS Print using PSIP to display the station's virtual channel as its former VHF analog channel 2.
These issues are greatly reduced with digital television, and today most over-the-air broadcasts take place on UHF, while VHF channels are being retired. To avoid the appearance of disappearing channels, digital broadcast systems have a virtual channel concept, allowing stations to keep their original VHF channel number while actually broadcasting on a UHF frequency. Over time a number of former television channels in the upper UHF band have been re-designated for other uses. Channel 37 was never used in the US and some other countries in order to prevent interference with radio astronomy. In 1983, the US FCC removed channels 70 through 83 and reassigned them to Land Mobile Radio System.
FM broadcasting started in Australian capital cities in 1947 on an "experimental" basis, using an ABC national network feed, consisting largely of classical music and Parliament, as a programme source. It had a very small audience and was shut down in 1961 ostensibly to clear the television band: TV channel 5 (102.250 video carrier) if allocated would fall within the VHF FM band (98–108 MHz). The official policy on FM at the time was to eventually introduce it on another band, which would have required FM tuners custom-built for Australia. This policy was finally reversed and FM broadcasting was reopened in 1975 using the VHF band, after the few encroaching TV stations had been moved.
WTVR-TV shut down its analog signal, over VHF channel 6, in the late morning of June 12, 2009, after more than 60 years, the official date in which full-power television stations in the United States transitioned from analog to digital broadcasts under federal mandate. The station's digital signal remained on its pre-transition UHF channel 25. Through the use of PSIP, digital television receivers continues to display the station's virtual channel as its former VHF analog channel 6. Prior to the transition, the audio component of WTVR's analog channel 6 signal at 87.75 MHz had been heavily promoted as available to listeners tuning to 87.7 on a standard FM radio receiver.
Furthermore, channel 6 abuts the FM broadcast band at 88 MHz, possibly causing and receiving interference from adjacent channels. (The FCC refused to remove this band from the bandplan, because taking the high UHF channels instead would bring in more money at auction. This also contradicts what has been done in every other country that has forced a DTV transition, all giving up the VHF bands.) A completely unaddressed issue is the use of HD Radio on 88.1 FM, where the lower sideband overlaps the far upper sideband of digital TV channel 6. The upper VHF (band III), including channels 7 to 13, is better about the above problems, but still not as good as the UHF band.
The station was built by the BBC in 1958 to provide a 405-line Band I (VHF) TV service and (later) a VHF (FM) radio services for north west Wales, including the Lleyn peninsula, Anglesey and the north Wales coast. ITV's service was provided from the Arfon transmitting station, approximately 20 miles to the south on the mainland. In 1967 the site became the area's main station for 625 line colour UHF TV, starting with just BBC Two in June of that year. By this time, it was policy to co-site all UHF TV services at the same site, and by 1973 Llanddona was broadcasting BBC One, BBC Two and ITV on UHF.
CCIR System I is an analog broadcast television system. It was first used in the Republic of Ireland starting in 1962 as the 625-line broadcasting standard to be used on VHF Band I and Band III, sharing Band III with 405-line System A signals radiated in the north and east405 Lines in Ireland (1961 - 1983) of the country. The UK started its own 625-line television service in 1964 also using System I, but on UHF only – the UK has never used VHF for 625-line television except for some cable relay distribution systems. Since then, System I has been adopted for use by Hong Kong, Macau, the Falkland Islands and South Africa.
If a VHF agent control station was discovered transmitting over a large area, and the VHF agent transmitter has not yet been DF'ed, then the first part of the search procedure was to pick up the agent on a receiver, i.e. to find the area around the agent transmitter where it could be heard from the ground. To find this ground wave area, three or four intercept search teams were assigned through the search area on a predefined plan, during the period the agents were scheduled to be on the air. Once the search teams reached the vicinity in which the agent was heard in their cars, they would mark the area on the map, and then leave.
WCAU signed on its digital signal on December 4, 1998. The station shut down its analog signal, over VHF channel 10, on June 12, 2009, the official date in which full-power television stations in the United States transitioned from analog to digital broadcasts under federal mandate. The station's digital signal moved from its pre-transition UHF channel 67 to channel 34 for post-transition digital operations, because ABC affiliate WHTM- TV in Harrisburg, Pennsylvania continued broadcasting on channel 10 after ceasing channel 27 analog transmission that day.FCC DTV status report for WCAU Through the use of PSIP, digital television receivers continue to display the station's virtual channel as its former VHF analog channel 10.1.
Before the All- Channel Receiver Act of 1962 required US television receivers to be able to tune the entire VHF and UHF range (which in North America was NTSC-M channels 2 through 83 on 54 to 890 MHz), a set-top box known as a UHF converter would be installed at the receiver to shift a portion of the UHF-TV spectrum onto low-VHF channels for viewing. As some 1960s-era 12-channel TV sets remained in use for many years, and Canada and Mexico were slower than the US to require UHF tuners to be factory-installed in new TVs, a market for these converters continued to exist for much of the 1970s.
The book observed that Turner "discovered his father had sheltered a substantial amount of taxable income over the years by personally lending it back to the company" and "discovered that the billboard business could be a gold mine, a tax-depreciable revenue stream that threw off enormous amounts of cash with almost no capital investment". In the late 1960s, Turner began buying several Southern radio stations. In 1969, he sold his radio stations to buy a struggling television station in Atlanta, UHF Channel 17 WJRJ (now WPCH). At the time, UHF stations did well only in markets without VHF stations, like Fresno, California, or in markets with only one station on VHF.
The VHF channel 3 allocation was contested between three groups that competed for approval by the FCC to be the holder of the construction permit to build and license to operate a new television station on the first commercial VHF allocation to be assigned to Shreveport. On June 27, 1952, one week before the FCC released a Report and Order reallocation memorandum that lifted a four-year moratorium on new television broadcast license applications, Shreveport-based KTBS Inc. (a family-led group owned by George D. Wray Sr., Edwin N. Wray Sr., George D. Wray Jr., Charles W. Wray and John A. Hendrick) filed the initial application for the permit. Another Shreveport-based company, International Broadcasting Corp.
