A mobile radio telephone Mobile radio telephone systems were telephone systems of a wireless type that preceded the modern cellular mobile form of telephony technology. Since they were the predecessors of the first generation of cellular telephones, these systems are sometimes retroactively referred to as pre-cellular (or sometimes zero generation, that is, 0G) systems. Technologies used in pre-cellular systems included the Push to Talk (PTT or manual), Mobile Telephone Service (MTS), Improved Mobile Telephone Service (IMTS), and Advanced Mobile Telephone System (AMTS) systems. These early mobile telephone systems can be distinguished from earlier closed radiotelephone systems in that they were available as a commercial service that was part of the public switched telephone network, with their own telephone numbers, rather than part of a closed network such as a police radio or taxi dispatch system.

Operating as a small independent concern, Stone found that he could not keep up with the advances in the industry, and in 1908 his company suspended operations, and was placed into receivership. Its assets, including its valuable portfolio of patents, were sold to Lee DeForest's Radio Telephone Company, for $10,000 cash and $300,000 of stock.Clark, page 117. In early 1911, he moved to New York City, once again working as a consultant.

However, botched air support by helicopter gunships causes several friendly casualties, to the horror of Lt. Eden and his radio telephone operator, Murphy. The assault fails and Duffy is among the fatalities. In between attacks, the shrinking platoon tries to rest, chattering about social upheaval and unrest back home. Bienstock is devastated by a letter from his girlfriend, whose college friends have told her that it is immoral to remain partnered with a soldier.
At about 08:40 or twenty minutes to nine, police had a call from the radio telephone operator from Windina to say that they heard a loud crash out in the hills, north of Nasevou village. Witnesses stated that they saw the aircraft was flying low, and shortly after slammed into the mountainside. One man stated that he heard a "cannonball" during the crash. He then saw parts from the tail fall down.
A radio-telephone and a Grinnell fire sprinkler system were installed. She was used to run Sunday ocean cruises out of Sydney Harbour and north to Broken Bay. It was the first time a Manly ferry had steamed up to Broken Bay since Binngarra and Burra Bra had been flagships for the annual regatta in the 1920s. The South Steyne also was used to follow the start of the Boxing Day Sydney to Hobart yacht races out to sea.
Pioneer radio station 2XG, also known as the "Highbridge station", was an experimental station located in New York City and licensed to the DeForest Radio Telephone and Telegraph Company. It was the first station to use a vacuum tube transmitter to make radio broadcasts on a regular schedule. From 1912 to 1917 Charles Herrold made regular broadcasts, but used an arc transmitter. He switched to a vacuum tube transmitter when he restarted broadcasting activities in 1921.
On May 5, 1945, General Slunečko ordered the Prague military headquarters, "Bartos," and all units outside Prague to revolt against the Nazi occupiers. At 11 A.M., under his direction, the Czech police occupied the radio, telephone exchange, railway station, main post office, and other strategic locations in the city. The Prague Uprising fully broke out at about noon. On May 8, Slunečko headed a delegation of the Czech National Council to which the German occupiers surrendered in Český Brod.
The FAA traditionally shared critical information using a variety of technologies, including radio, telephone, Internet, and dedicated connections. However, the agency leveraged new information management technologies to improve information delivery and content. In 2007, the FAA established the SWIM program to implement a set of information technology principles in the National Airspace System (NAS) and provide users with relevant and commonly understandable information. SWIM facilitates NextGen's data-sharing requirements, serving as the digital data-sharing backbone.
Ivan Dixon as Kinchloe, talking to Hogan Staff Sergeant James Kinchloe (portrayed by Ivan Dixon) – United States Army Air Corp Staff Sergeant James "Kinch" Kinchloe is primarily responsible for radio, telephone, and other forms of electronic communications. Although outranked by TSgt. Carter, Kinch acts as second in command in Hogan's crew and is Chief of Operations. It was a large step for a 1960s television show to have an African-American actor identified in such a manner.
The receiving station licences initially cost $1 and had to be renewed yearly. They were issued by the Department of Marine and Fisheries in Ottawa, by Departmental Radio Inspectors, and by postmasters located in the larger towns and cities, with licence periods coinciding with the April 1-March 31 fiscal year."Radiotelegraph Regulations: Licenses", The Canada Gazette, September 23, 1922, page 1."Radio Telephone Receiving Sets Must Be Licensed", Calgary Daily Herald, April 19, 1922, page 9.
A barge leaves the landing ramp in Nukunonu to collect cargo and passengers from the MV Tokelau Tokelau has a radio telephone service between the islands and to Samoa. In 1997, a government-regulated telephone service (TeleTok) with three satellite earth stations was established. Each atoll has a radio-broadcast station that broadcasts shipping and weather reports and every household has a radio or access to one. News is disseminated through the government newsletter Te Vakai.
The paper's review of the potential benefits of the new service was enthusiastic: "Although radio news service is still in its infancy, there is every evidence that it is only a question of a very few months when it will be considered as an imperatively necessary source of information." and "It is not a fad. It is an industrial revolution.""Radio Telephone License Granted to Constitution", Atlanta Constitution, March 17, 1922, pages 1-2. WGM's debut broadcast began at 7:00 p.m.
"Hotel Oakland Has Radio Telephone", Pacific Radio News, October 1921, page 97. He installed 6XAJ atop the Hotel Oakland as an adjunct to his Western Radio Institute, which occupied two rooms on the hotel's seventh floor."Wireless Phone Will Broadcast Sunday Sermon", Oakland (California) Tribune, September 25, 1921, page A-3. Beginning in September 1921 the station transmitted on 325 meters (923 kHz), and its schedule included "Press matter" supplied by the Oakland Tribune, broadcast daily from 7:15-7:30 p.m.
A NAVTEX broadcast includes maritime navigation warnings, weather forecasts, ice warnings, Gulf Stream locations, radio navigation information, rescue messages, and marine advisories. Each station has 2 NAVTEX transmitters. Besides broadcast messages, Coast Guard stations handle direct traffic between aircraft, cutters, boats, and shore stations on VHF, MF, and HF frequencies, including the HF Data Link encrypted e-mail system and Digital Selective Calling (DSC), which uses radio telephone to send digitally encrypted signals to either one receiver or a group or receivers.
De Forest transferred the station's transmitter to the California Theater building in San Francisco, where it was relicensed as 6XC, and in the spring of 1920 it began daily broadcasts of the theater's orchestra. De Forest later stated this was the "first radio-telephone station devoted solely" to broadcasting to the public."'Broadcasting' News by Radiotelephone" (letter from Lee de Forest), Electrical World, April 23, 1921, page 936. 6XC was relicensed as broadcasting station KZY in late 1921, and deleted a year later.
Old Crow is served by Northwestel since 1971. The long distance connection originally relied on a microwave relay at Rat Pass near the Yukon/NWT border, which also provide a radio-telephone base station along the Dempster Highway, but it was frequently out of service in winter when weather conditions made helicopter access hazardous. In the late 1980s, a satellite ground station was installed in Old Crow, providing more reliable service. The long distance connection is noteworthy for two minor incidents.
The island has a well-placed jetty, 4 primary schools, not including Vanuavatu, which has its own, a Post office/shop, and radio- telephone stations at Ketei and Dravuwalu. It is accessible technologically by satellite phone provided by Telecom Fiji, but not mobile cellular phones. The island has 4 villages with Tovu, the capital and seat of the Turaga na Roko Sau whose household site is known as "Mataiilakeba". Ketei is the seat of Tui Ketei, traditionally known as Ramalo, the King maker.
In 1983, as the federal government's breakup of the Bell telephone monopoly increased competition in the telecommunications industry dramatically, Rochester Telephone launched its second unregulated venture, founding the RCI Corporation. RCI installed a microwave communications network in New York State and a fiber optic hookup with Chicago. After purchasing an additional fiber optic link with Washington, D.C., the company's operations spanned 12 cities. In the mid-1980s, Rochester Telephone also entered the new radio telephone industry, when it founded Rochester Tel Mobile Communications.
Bancroft Gherardi Jr. (April 6, 1873 - August 14, 1941) was a noted American electrical engineer, known for his pioneering work in developing the early telephone systems in the United States. Recognized as one of the foremost authorities in telephone engineering, Gherardi was instrumental in developing the transcontinental telephone service in 1915 and the trans-Atlantic radio telephone service in 1927. He was award the IEEE Edison Medal in 1932 for "contributions to the art of telephone engineering and the development of electrical communication".
Lilongwe Hotel is a hotel located on the main city road in Area 3, Capital Hill, Bwaila West in Lilongwe, Malawi. It is located near Lilongwe International Airport and often serves as a venue for meetings and conferences, which can accommodate up to 150 delegates. The hotel has 90 rooms with bathrooms and radio, telephone, fax and satellite television facilities. The Cocktail Bar and Malingunde Bar are located in the hotel and the features live music seven days a week.
The Secret Service subsequently reconfigured a Douglas C-54 Skymaster for duty as a presidential transport. This VC-54C aircraft, nicknamed the Sacred Cow, included a sleeping area, radio telephone, and retractable elevator to lift Roosevelt in his wheelchair. As modified, the VC-54C was used by President Roosevelt only once, on his trip to and from the Yalta Conference in February 1945. In the postwar period, governments around the world have instituted similar provisions for the official aerial transportation of their heads of state and government.
New Jersey Telephone Herald entertainers The birth of public radio broadcasting had an immediate impact on radio broadcasting as it stimulated the idea of having additional musical programs. The next month on February 24th the Manhattan Opera Company's new opera singer Mariette Mazarin sang "Love is a rebellious bird" from Carmen over a transmitter located in DeForest's laboratory."Radio Telephone Experiments", Modern Electrics, May 1910, page 63. (earlyradiohistory.us) This radio concert was heard by a group of scientists, diplomats, newspaper reporters and the public within .
By the end of the 1980s, satellite communications had started to take an increasingly large share of the station's business, and a program of severe rationalisation was started, leading to the closure of two transmitting sites at Leafield and Ongar. The transmitting site at Portishead closed on 31 December 1978, followed by the site at Dorchester in 1979. In the station's penultimate year to March 1999, there were on average per month 571 radio telegrams, 533 radio telephone calls, and 4,001 radio telex calls.
Choctaws in training in World War I for coded radio & telephone transmissions In the closing days of World War I, a group of Oklahoma Choctaws serving in the U.S. Army used their native language as the basis for secret communication among Americans, as Germans could not understand it. They are now called the Choctaw Code Talkers. "Choctaw Indian Code Talkers of World War I" (notes/letters), Phillip Allen, Oklahoma University, 2000, webpage: CodeTalkers .

In the United States Army, rifle platoons are normally composed of 42 soldiers. They consist of three rifle squads, one weapons squad, and a six-man headquarters. The headquarters consists of a Platoon Leader (PL)--usually a second lieutenant (2LT), a Platoon Sergeant (PSG)--usually a Sergeant First Class (SFC, E-7), a radio- telephone operator (RTO), a platoon forward observer (FO), the FO's RTO, and the platoon medic. Each squad is led by a Sergeant, who is usually a Staff Sergeant (SSG, E-6).
Nelson was attached to the staff of 1st Marine Brigade under Brigadier General Louis M. Little. He was stationed at Port-au-Prince and served simultaneously as Brigade Signal Officer and Officer-in-Charge of Haitian government radio, telephone and international communications system. For his service in this capacity, Nelson was decorated with Haitian National Order of Honour and Merit, rank Officer. He returned to the United States in August 1934 and assumed duty as an instructor at the Basic School at Philadelphia Navy Yard.
Britain, the U.S. and Israel denied these allegations. On June 8, Egyptian credibility was further damaged when Israel released an audio recording to the press, which they said was a radio- telephone conversation intercepted two days earlier between Nasser and King Hussein of Jordan."Israelis say tape", 9 June 1967. In the immediate aftermath of the war, as the extent of the Arab military defeat became apparent, Arab leaders differed on whether to continue to assert that the American military had assisted the Israeli victory.
De Forest (1950) page 327. In October 1915 AT&T; conducted test radio transmissions from the Navy's station in Arlington, Virginia that were heard as far away as Paris and Hawaii. Audion advertisement, Electrical Experimenter magazine, August 1916 The Radio Telephone Company began selling "Oscillion" power tubes to amateurs, suitable for radio transmissions. The company wanted to keep a tight hold on the tube business, and originally maintained a policy that retailers had to require their customers to return a worn-out tube before they could get a replacement.

To disrupt British radio transmissions, Wolfgang Martini's unit, the Funkhorchdienst (Radio Enlightening Service, or Signals intelligence) attempted to jam radio-telephone frequencies. They created a subtle jamming technique which increased atmospheric interference which degraded the performance of British coastal radars. In addition Dornier Do 217s of Kampfgeschwader 2 (Bomber Wing 2) was ordered to fly electronic deception missions over the western channel to divert enemy aircraft. Joachim Coeler's Fliegerkorps IX prepared to strike at RAF bases in south-west England and to engage and slow down British naval forces that might attempt an interception.
"Will Give Concert by Wireless Telephone", San Jose Mercury Herald, July 21, 1912, page 27. An even more ambitious effort took place in the fall of 1916, after the De Forest Radio Telephone & Telegraph Company began operating an experimental radio station, 2XG, in New York City. Lee de Forest made an arrangement with the Columbia Gramophone record company to broadcast phonograph records from their offices—the phonograph company supplied records in exchange for "announcing the title and 'Columbia Gramophone Company' with each playing".Father of Radio: The Autobiography of Lee de Forest, 1950, page 337.

The microphones of the day were of poor quality and could not pick up most of the singing on stage. Only off-stage singers singing directly into a microphone could be heard clearly. The New York Times reported the next day that static and interference "kept the homeless song waves from finding themselves"."Wireless Melody Jarred," The New York Times, Friday, January 14, 1910, page 2 De Forest's Radio Telephone Company manufactured and sold the first commercial radios in the demonstration room at the Metropolitan Life Tower in New York City for this public event.
It linked via SHF voice and morse radio to Hillingdon, West London, and via large UHF tropo-scatter dishes to the ballistic early warning base at Fylingdales (Yorkshire), Flobecq (Belgium) and the Hook of Holland. Eventually, with additional capacity in mind, it acquired six steel masts. Its personnel were supplied from the nearby Bentwaters airbase. From 1966 its main building housed one of the two "Autovon" (US radio telephone automatic exchanges) in the UK. Between 1988 and 1990 it progressively shut down, though the buildings and 3 masts remain.
Edwin Henry Colpitts (January 19, 1872 - March 6, 1949) was a communications pioneer best known for his invention of the Colpitts oscillator. As research branch chief for Western Electric in the early 1900s, he and scientists under his direction achieved significant advances in the development of oscillators and vacuum tube push–pull amplifiers. In 1915, his team successfully demonstrated the first transatlantic radio telephone. Colpitts died at home in 1949 in Orange, New Jersey, United States and his body was interred in Point de Bute, New Brunswick, Canada.
KZY was a radio station located in Oakland, California, that was licensed to the Atlantic-Pacific Radio Supplies Company from December 9, 1921 until its deletion on January 24, 1923. It, and the Preston D. Allen station, KZM, were the first broadcasting stations licensed to Oakland."New Stations: Commercial Land Stations", Radio Service Bulletin, January 3, 1922, page 2. KZY was the successor to Experimental station 6XC, which dated to mid-1920, and which founder Lee de Forest suggested deserved credit as the "first radio-telephone station devoted solely" to broadcasting to the public.
The original wooden lighthouse was burnt down in 1943 by a man who had recently left a psychiatric hospital and made his way down to Coal Island across the fjord from the lighthouse. He decided the light was a deliberate plot to keep him awake at night by shining in his window so took matters into his own hands. He held all the keepers hostage with a rifle, smashed the radio telephone and set fire to the lighthouse. The concrete lighthouse which replaced it has now in turn been replaced by two automated beacons.
The first radio antenna used to identify an astronomical radio source was one built by Karl Guthe Jansky, an engineer with Bell Telephone Laboratories, in 1932. Jansky was assigned the job of identifying sources of static that might interfere with radio telephone service. Jansky's antenna was an array of dipoles and reflectors designed to receive short wave radio signals at a frequency of 20.5 MHz (wavelength about 14.6 meters). It was mounted on a turntable that allowed it to rotate in any direction, earning it the name "Jansky's merry-go-round".
However, due to technical and financial issues, he had made little progress in making converts to the idea. In late 1916 the DeForest Radio Telephone & Telegraph Company began broadcasting a nightly "wireless newspaper" entertainment and news program from its experimental station, 2XG, located in the Highbridge section of New York City."Wireless Newspaper Wafted Out to Sea", New York Tribune, November 7, 1916, page 5. This station had to suspend operations during World War One, but was revived shortly after the October 1, 1919 lifting of the wartime ban on civilian stations.
Station advertisements included the slogan "Canada's First Station"."In Montreal it's CFCF" (advertisement), Sponsor, August 13, 1951, page 70. In April 1922 the Canadian government began issuing the first licences specifically for "radio-telephone broadcasting stations". Initially all these stations received four-letter call signs starting with "CF", "CH", "CJ" or "CK", plus one additional "C" as the third or fourth letter. Included in the first group of twenty-three stations was a Montreal grant for Canadian Marconi, assigned a transmitting wavelength of 440 metres (682 kHz) and the call letters CFCF.
Along with increased trade and the development of townships, the number of telephone subscribers in Peninsular Malaysia increased significantly. By 1930, to deal with the volume of telephony traffic, an automated magneto exchange was commissioned in Kuala Lumpur on Jalan Weld. In the 1930s, all telephone exchanges in the Malayan Trunk System could communicate with exchanges in Java, the Philippines, the US, Canada and Mexico using shortwave radio-telephone transmitters. Towards the end of the decade, a Marconi Radio Terminal was installed at the Kuala Lumpur Telephone Exchange to handle overseas calls.
Versions of the Altay system are still in use today as a trunking system in some parts of Russia. In 1959 a private telephone company located in Brewster, Kansas, USA, the S&T; Telephone Company, (still in business today) with the use of Motorola radio telephone equipment and a private tower facility, offered to the public cellular telephone services in that local area of NW Kansas. In 1966, Bulgaria presented the pocket mobile automatic telephone RAT-0,5 combined with a base station RATZ-10 (RATC-10) on Interorgtechnika-66 international exhibition.
The "directing ship" tracked the target submarine on ASDIC from a position about 1500 to 2000 yards behind the submarine. The second ship, with her ASDIC turned off and running at 5 knots, started an attack from a position between the directing ship and the target. This attack was controlled by radio telephone from the directing ship, based on their ASDIC and the range (by rangefinder) and bearing of the attacking ship. As soon as the depth charges had been released, the attacking ship left the immediate area at full speed.
The tactical data links exchange data between other units in the force; i.e., ships, aircraft and other military units such as deployed Army, Air Force, Marine and Coast Guard commands. They operate encrypted and non-encrypted long and short range radio-telephone equipment as well as intra-ship communication systems. With specialized training, they also may serve as combat air controllers for helicopters, anti-submarine patrol aircraft, and jet strike fighter aircraft in anti-submarine tactical air controller (ASTAC), sea combat air controller (SCAC), and air intercept controller (AIC) roles.
The Daily Sitka Sentinel reported in its 10 May 1951 edition that the vessel had been renamed Clatsop and was the property of Mr. and Mrs. Don Martin and that Don Martin had had self-steering gear, a radio direction finder, a radio telephone, and a bug shoe installed aboard her. It also reported that Martin planned to depart Sitka on 11 May 1951 for a tuna-fishing trip aboard Clatsop, planning to start off Guadalupe, Baja California, Mexico, and then work his way north along the coast of California as far as Monterey.
Stickland worked as a scientific civil servant at the Radio Research Station between 1928 - 1947. She worked with radar pioneer, Robert Watson-Watt, on long-wave propagation, Reginald Smith-Rose on short-wave propagation, and Edward Appleton on the properties of the ionosphere. Stickland, along with Smith-Rose, read a paper entitled 'Ultra-Short Wave Propagation - Comparison Between Theory and Experimental data' at the Institution of Electrical Engineers. The paper described the results of field intensity measurements obtained between 1937-39 using the Post Office radio-telephone link between Guernsey and Chaldon.
Celcom Axiata Berhad, DBA Celcom, is the oldest mobile telecommunications provider in Malaysia. Celcom is a member of the Axiata group of companies. Being one of the very few companies in Malaysia to originally obtain a cellular phone license, it successfully introduced mobile telephony in Malaysia through its ART-900 (Automatic Radio Telephone) service, using first- generation (analogue) ETACS (Extended Total Access Communication System) specifications of the United Kingdom, a derivative of the US-AMPS (Advanced Mobile Phone System) technology. The ETACS ART-900 was started using the prefix "010".
Charles Gilbert was the treasurer of the company. The De Forest System was adopted by the United States Government, and had been demonstrated to other Governments including those of Great Britain, Denmark, Germany, Russia, and British Indies, all of which purchased De Forest apparatus previous to the Great War. De Forest is one of the fathers of the "electronic age", as the Audion helped to usher in the widespread use of electronics.Weiss, G., & Leonard, J. W. (1920) "De Forest Radio Telephone and Telegraph Company", America's Maritime Progress, New York: New York marine news Co., p. 254.
During 1942, Vivien had Type 285 fire control radar installed for her 4-inch (102-mm) guns. On 24 February 1943, she and the escort destroyer were escorting Convoy FS 137 when they engaged German minelaying motor torpedo boats which attacked the convoy east-southeast of Great Yarmouth. During 1944, Vivien was fitted with surface warning radar, as well as radio telephone equipment to improve her ability to cooperate with other ships and aircraft. She did not take part in any of the operations related to the Allied invasion of Normandy in the summer of 1944.
Jones and ffolliott attempt to save him, but are unsuccessful. They are rescued by an American ship, the Mohican. The captain refuses to allow the reporters to file their story using the ship's communications citing American neutrality in the war, but Jones, ffolliott, and Carol surreptitiously communicate the story by radio-telephone to Mr. Powers. Later, back in London and now a successful war correspondent, Jones, with Carol at his side, describes London being bombed in a live radio broadcast to the United States, urging Americans to fortify their country and "keep the lights burning" as they go dark in the studio.
In mid-December 1921 it was announced that Western Radio Electric, now at 550 South Flower Street, was installing "a powerful 50-watt continuous wave transmitter" at the Kinema Theater at Seventh and Grand Streets, and "the orchestra selections, organ solos and songs from the stage will be broadcasted through space"."Kinema Installs Radio Telephone To Transmit Music", Los Angeles Herald, December 17, 1921, page B-2. On February 2, 1922, the station's call letters were changed from KZC to KOG, although no reason given for the change."Alterations and Corrections", Radio Service Bulletin, April 1, 1922, page 7.
A contemporary wire report stated that Hayes expressed the hope that "in the near future radio phones could be utilized to broadcast weather and market reports and other information"."Radio Telephone", New Britain (Connecticut) Herald, September 2, 1921, page 4. Shortly thereafter the Commerce Department, which regulated radio at this time, issued a regulation formally creating a radio broadcasting service classification. Effective December 1, 1921, broadcasting stations could be established which held Limited Commercial licenses that authorized operation on two designated broadcasting wavelengths: 360 meters (833 kHz) for "entertainment", and 485 meters (619 kHz) for "market and weather reports".
The company started in 1984 as Hutchison Telecom Hong Kong, a telecommunications company that is granted licence to operate Advanced Mobile Phone Service (AMPS) cellular radio telephone network in Hong Kong. Afterwards, 3 launched Hong Kong's first analogue mobile telecommunications services in 1985. In 1995, 3 launched their GSM service. In 1998, 3 pushed their first dual-band network in Hong Kong, which is Asia's first dual-band network. In May 2004, its affiliated 2G operator Orange re-branded its services and changed its name to "3 Dualband", referring to the GSM product, and "3 CDMA", referring to the CDMA product.
Positioned immediately down slope to the south-west of the hut lies an iron "I" beam which may have been a radio aerial or mast. Surrounding the hut and the mast are scatters of artefacts including numerous large black Dunlop brand batteries, CGI sheets, white ceramic fragments, timber posts, wire cable, window glass, and window latches. Extending down the ridgeline from the hut to the main lazaret pathway are collapsed telephone line poles. The hut housed a small petrol generator to charge a set of batteries and a rack holding a single channel radio-telephone to Palm Island.
On September 6, 1947, he became mayor of Cebu City until 1951, succeeding Dr. Luis Espina. During his term, he was responsible in the repair and reconstruction of the four-story, colonnaded Cebu City Hall with War Damage Funds. Additionally, the first radio telephone circuit established between Manila and Cebu was inaugurated on March 1, 1950 under the term of then President Elpidio Quirino, with the first official three-minute conversation between then former President Sergio Osmeña and Raffiñan. In 1947, the city council passed an ordinance exacting fees on each ticket sold in local theaters.
A mobile radio telephone Radio Common Carrier or RCC was a service introduced in the 1960s by independent telephone companies to compete against AT&T;'s IMTS. RCC systems used paired UHF 454/459 MHz and VHF 152/158 MHz frequencies near those used by IMTS. RCC based services were provided until the 1980s when cellular AMPS systems made RCC equipment obsolete. Some RCC systems were designed to allow customers of adjacent carriers to use their facilities, but equipment used by RCCs did not allow the equivalent of modern "roaming" because technical standards were not uniform.
This proved to be impossible, because the extreme conditions prevented the deckhands from releasing the securing pin on the bow rudder, and the Captain then made a decision to try to reach Northern Ireland by adopting a course which would keep the stern of the craft sheltered from the worst of the elements. At 0946 hrs, two hours after leaving Stranraer a message was transmitted in Morse code (Princess Victoria did not have a radio telephone) by radio operator David Broadfoot to the Portpatrick Radio Station: "Hove-to off mouth of Loch Ryan. Vessel not under command. Urgent assistance of tugs required".
A radio telephone was installed in 1935, and in 1953 a telephone cable was laid. A red telephone box was installed in the centre of the island, symbolic of the 6 millionth phone box installation in the UK. It is still there today, though no longer in use. It was not until 1894 that Stroma gained its first artificial landing point, a pier built from Portland cement near Nethertown at a cost of £800. In 1955, Caithness County Council constructed a new harbour on the south coast of the island at the then great cost of £28,500.
" The Mani-Nama blog reviewed the performance saying, "The set was quite modest- a realistic one with an old radio, telephone and chairs. After sometime I witnessed some quality lighting which was done by Shakeel Siddique, who literally set the pace of play with classic lights." and The News on Sunday wrote, "Kamra #9 provided insight into human complexities." Aleeza Rasool, writer and critic, of Youlin Magazine reported praising the performance as she wrote, "Firstly, a radio play by Manto was a refreshing choice, for it is one of the lesser-known genres that Manto composed during his brief lifetime.
A 70 W antenna power emergency transmitter carried telegraph and radio telephone signals over 300–1,300 m wavelength bands. The main aerial consisted of two lead-weighted -long wires deployed by electric motor or hand crank; the emergency aerial was a wire stretched from a ring on the hull. Three six-tube receivers served the wavelengths from 120 to 1,200 m (medium frequency), 400 to 4,000 m (low frequency) and 3,000 to 25,000 m (overlapping low frequency and very low frequency). The radio room also had a shortwave receiver for 10 to 280 m (high frequency).
Advanced training in bombardment and observation, like that in pursuit, entailed work in classrooms and hangars as well as in the air. Students flew DH-4s and were schooled in flying, bombsights, camera obscura, gunnery, and, among other things, the history of the development of aviation. At the Observation School, students transitioned to and learned DH-4 airplanes. There were courses on formation and cross-country flying; visual and photographic reconnaissance; surveillance; intelligence; liaison with ground forces; observation and adjustment of artillery fire; map reading; meteorology; maintenance and operation of radio, telephone, and telegraph; Liberty engines; and rigging.
The 362nd Signal Company was deployed in Vietnam from 23 March 1962, to 15 March 1973, as part of the 39th Signal Battalion. The 362nd was deployed from the Delta to the DMZ, providing long range Tropo-Scatter radio telephone communications throughout South Vietnam, with one site in Udorn Air Force Base in Thailand. In early 1964, the site in Ubon was no longer part of the 362nd Signal. By mid 1964, the 362nd operated Microwave Communications sites in Soc Trang, Vinh Long, Phulam (near Saigon), Nha Trang, Quinhon, Danang, Hue, Quang Ngai, Pleiku, Ban Me Thuot and Gia Nghia.
Overall, United Wireless' six-year dominance of U.S. radio communications had a strong negative impact, in part due to the skepticism and disrepute it and other fraudulent U.S. companies brought to the fledgling industry. (Two other major fraudulent firms prosecuted in 1912 were de Forest's Radio Telephone Company, and the Continental Wireless Telephone and Telegraph Company, led by A. Frederick Collins). Reviews of the United era were not completely negative. By providing radio equipment and operators below cost to freighters and small passenger vessels, which normally would not have been able to afford the service, United helped save the lives of endangered seafarers now able to summon assistance during emergencies.
California Historical Landmark No. 836, located at the eastern corner of Channing Street and Emerson Avenue in Palo Alto, California, stands at the former location of the Federal Telegraph laboratory, and references Lee de Forest's development there, in 1911–1913, of "the first vacuum-tube amplifier and oscillator". In May 1910, the Radio Telephone Company and its subsidiaries were reorganized as the North American Wireless Corporation, but financial difficulties meant that the company's activities had nearly come to a halt. De Forest moved to San Francisco, California, and in early 1911 took a research job at the Federal Telegraph Company, which produced long-range radiotelegraph systems using high-powered Poulsen arcs.
Radio station 2XG, also known as the "Highbridge station", was an experimental station located in New York City and licensed to the De Forest Radio Telephone and Telegraph Company from 1915-1917 and 1920-1924. In 1916 it became the first radio station employing a vacuum-tube transmitter to make news and entertainment broadcasts on a regular schedule,From 1912 to 1917 Charles Herrold made regular radio broadcasts, but operated an arc-transmitter. He would switch to a vacuum-tube transmitter when he resumed broadcasting activities in 1921. and, on November 7, 1916, became the first to broadcast U.S. presidential election returns by spoken word instead of Morse code.
During the 1950s and 1960s, the 501 radio patrol cars were widely used as police vehicles by many police departments in Bavaria, including Bavarian State Police and Munich City Police (Stadtpolizei München). The car with its relatively fast 145 km/h (90 mph) top speed by 1950s standards, was a blessing for police, as most criminals did not have easy access to faster cars like Mercedes-Benz 300 SL or Porsche. The traffic police units for country roads and Autobahns were even issued V8-powered cars, which were even faster. The police cars also featured a Lorenz radio telephone, allowing police officers to easily communicate with the dispatch.
The escorts believed that it was Raccoon dropping depth charges on a suspected contact. Q-065 later reported seeing two columns of white water out in the Gulf of St. Lawrence. Arrowhead turned and sailed to Raccoons position in the convoy defence but found no trace of the ship in the poor visibility and Raccoon was not equipped with a radio-telephone. Unable to find the ship, Arrowhead broke off the search as convoy escort took precedence and returned to its position at the head of the convoy. The convoy sailed on until after daybreak, when the convoy was picked up again by a U-boat, this time U-517.
Federal Signal Model 5 in Ballston Spa, New York, U.S. Sirens are sometimes integrated into a warning system that links sirens with other warning media, such as the radio and TV Emergency Alert System, NOAA Weather Radio, telephone alerting systems, Reverse 911, Cable Override, and wireless alerting systems in the United States and the National Public Alerting System, Alert Ready, in Canada. This fluid approach enhances the credibility of warnings and reduces the risk of assumed false alarms by corroborating warning messages through multiple forms of media. The Common Alerting Protocol is a technical standard for this sort of multi-system integration. Siren installations have many ways of being activated.
A U.S. Marine artillery forward observer in a tree to get a better view of the battlefield in Guadalcanal, 1942. In the U.S. Army, a Light, Heavy, or Stryker Infantry company Fire Support Team (FIST) consists of a Fire Support Officer (FSO), a Fire Support Sergeant, three Forward Observers (FO), two Fire Support Specialists and three Radio Telephone Operators (RTO). Armored/Cavalry FIST teams usually consist of just one FSO and three enlisted personnel. Brigade COLT teams operate in groups of two individuals, a Fire support specialist in the grade of E-1 to E-4 and a Fire Support Sergeant in the grade of E-5.
Raymond A. Heising (1922) Raymond A. Heising (August 10, 1888 - January 1965) was an American radio and telephone pioneer. Heising was born in Albert Lea, Minnesota, graduated in 1912 in electrical engineering from the University of North Dakota, and in 1914 received his master's degree from the University of Wisconsin–Madison. From 1914 until his retirement in 1953, Dr. Heising worked for the Western Electric Company and Bell Labs, and subsequently as a consulting engineer and patent agent. Heising played a major role in the development of military radio telephone systems in World War I, and for transoceanic and ship-to-shore public communications.
The St Romanus sailed from Hull on 10 January 1968 and the last firm contact with the vessel was a radio telephone call the same evening. However, despite a company policy that ships should report their position and catch details daily, the alarm was not raised until 26 January, after a number of failed attempts by the owners to contact the ship by radio. It was then discovered that a liferaft found on 13 January by another vessel had come from the St Romanus. A search began, but by 30 January the families were told that there was little hope for the vessel and her crew of 20.
In 1939 he transferred to the television research group at Bell Laboratories. With the approach of war emergency in 1940, he returned to Specialty Products at Bell Laboratories where he supervised the circuit development of a number of radars for aircraft and ground service. By 1947, he was directing the efforts of a group engaged in the development of radar for commercial applications and of radio-telephone sets for aircraft and shipboard service. 1961, he was appointed by the FAA Administrator Najeeb Halaby to be a member of Project Beacon,Project Beacon a group which published the "Report of the Task Force on Air Traffic Control" in October 1961.
If the casualty has injuries the rescuers will need to provide first aid and prepare the casualty to be transported to professional medical help. See main article: first aid. In the developed world, transporting a diving casualty to hospital or a recompression chamber may be as simple as contacting the marine emergency services, generally by using marine VHF radio, telephone or a distress signal, and arranging a lifeboat or helicopter. If a diving injury such as decompression sickness is suspected, the success of recompression therapy as well as a decrease in the number of recompression treatments required has been shown if first aid oxygen is given within four hours after surfacing.
Sheba Telecom (Pvt.) Ltd. was granted license in 1989 to operate in the rural areas of 199 upazilas. Later it obtained nationwide 15-year GSM license in November 1996 to extend its business to cellular mobile, radio telephone services. It launched operation in the last quarter of 1997 as a Bangladesh-Malaysia joint venture. Gulshan. In July 2004, it was reported that Egypt based Orascom Telecom is set to purchase the Malaysian stakes in Sheba Telecom through a hush-hush deal, as Sheba had failed to tap the business potentials in Bangladesh mainly due to a chronic feud between its Malaysian and Bangladeshi partners.
Klejn himself holds that his communication theory of cultural evolution is his most interesting contribution to anthropology, although he could not succeed in working out this theory in detail (it is presented only in some minor articles). Many modern students imagine culture as a certain amount of information. But if so, then the transmission of culture from one generation to the next can be presented as a net of communication spread over time rather than in space alone. In that case, the flow of information will be exposed to the impact of the same factors as influence any chain of communication (radio, telephone etc.).

KONA 8, which was formed in October 1944, and was assigned to the Eastern Front Army Group South. It had one Evaluation Centre: NAAS 8, 2 Signal Intelligence Battalions, NAA 1 and NAA 2, one Long Range Battalion: FAK 620, one Close Range Signal Intelligence Company whose identity is unknown, and one Stationary Intercept Company, either Feste 4 or Feste 8. It was known that Feste 8 attempted in the winter of 1942-3 to intercept Russian radio telephone traffic at Königsberg, but is not certain to what eastern KONA this Feste was assigned.IF-123, Page 3 KONA 8 operated in Odessa, Romania, Croatia, and finally Linz.
In 1974, he gained admission to the university's School of Public Communications. He then studied for a diploma at the Radio Engineering Institute of Electronics in Fredericksburg, Virginia, in July 1975, which earned him a first-class radio- telephone operator license, a required certificate for all radio broadcasters at the time, which was issued by the Federal Communications Commission. With the license, Stern landed his first professional radio job at WNTN in Newton, Massachusetts from August to December 1975 doing air shifts, news casting, and production work. For the next five months, he taught students basic electronics in preparation for their own FCC exams.
Broadcasting antenna in Stuttgart Broadcasting is the distribution of audio or video content to a dispersed audience via any electronic mass communications medium, but typically one using the electromagnetic spectrum (radio waves), in a one-to-many model. Broadcasting began with AM radio, which came into popular use around 1920 with the spread of vacuum tube radio transmitters and receivers. Before this, all forms of electronic communication (early radio, telephone, and telegraph) were one-to-one, with the message intended for a single recipient. The term broadcasting evolved from its use as the agricultural method of sowing seeds in a field by casting them broadly about.
This practice was universally adopted, and the word "radio" introduced internationally, by the 1906 Berlin Radiotelegraphic Convention, which included a Service Regulation specifying that "Radiotelegrams shall show in the preamble that the service is 'Radio'". The switch to "radio" in place of "wireless" took place slowly and unevenly in the English-speaking world. Lee de Forest helped popularize the new word in the United States—in early 1907 he founded the DeForest Radio Telephone Company, and his letter in the June 22, 1907 Electrical World about the need for legal restrictions warned that "Radio chaos will certainly be the result until such stringent regulation is enforced"."Interference with Wireless Messages", Electrical World, June 22, 1907, page 1270.
During World War I, civilian radio stations had been banned in the United States. After the end of the war, radio broadcasting, which had previously been done on a limited, mostly experimental basis, began to become better organized, and saw the entrance of major established corporations. In the New York City area, beginning in late 1919 the De Forest Radio Telephone Company transmitted a nightly news and entertainment broadcast over its experimental station, 2XG, located in the Highbridge section of the Bronx, in New York City. However, in early 1920 the local government Radio Inspector shut down 2XG's operation on technical grounds, and Lee de Forest responded by transferring his broadcasting efforts to station 6XC in San Francisco.
Versions of the Altay system are still in use today as a trunking system in some parts of Russia. In 1959 a private telephone company in Brewster, Kansas, USA, the S&T; Telephone Company, (still in business today) with the use of Motorola Radio Telephone equipment and a private tower facility, offered to the public mobile telephone services in that local area of NW Kansas. This system was a direct dial up service through their local switchboard, and was installed in many private vehicles including grain combines, trucks, and automobiles. For some as yet unknown reason, the system, after being placed online and operated for a very brief time period, was shut down.
Each team consisted of one pilot for Atlantic runs (or two pilots for voyages to Russia, Gibraltar, or the Mediterranean Sea), with one fitter, one rigger, one radio-telephone operator, one FDO, and a seaman torpedoman who worked on the catapult as an electrician. MSFU crews signed ship's articles as civilian crew members under the authority of the civilian ship's master. The ship's chief engineer became responsible for the catapult, and the first mate acted as catapult duty officer (CDO), responsible for firing the catapult when directed. The single Hurricane fighter was launched only when enemy aircraft were sighted and agreement was reached using hand and flag signals between the pilot, CDO, and ship's master.
Many national and regional Aboriginal organizations voiced the same fear, and insisted that native people had the right to define and contribute to any broadcast service distributed in their homelands. The newly formed Inuit Tapirisat of Canada was determined that Inuit would not become just a new market for existing southern services in English and French: they insisted that communities should be permitted to define their own communications environment, and that Inuit should be able to contribute to the Canadian broadcasting system in a significant way. One of ITC’s first major policy statements called on the federal government to ensure Inuit control over the expansion of radio-telephone, community radio, videotape, and newspaper services into the Arctic.Roth, p. 106.
In its various incarnations, especially as CFCF, station staff often asserted that, based on its May 20, 1920 debut broadcast, their station was not only the oldest in Canada, but the first to ever make a "scheduled broadcast". This claim is not widely accepted, because there are numerous examples of earlier publicized radio broadcasts in multiple countries. This is especially true in the United States, which recorded its first regular weekly broadcasts in 1912, conducted by Charles Herrold in San Jose, California. The De Forest Radio Telephone and Telegraph Company's station, 2XG in New York City, also conducted regular broadcasts from October 1916 to April 1917, which were resumed in the fall of 1919.
Meanwhile, the band above 105 MHz had been filled with land-based mobile radio-telephone users (taxis, police and others). New Zealand's FM frequency allocation issue was not fixed until the late 1990s, after those users had been reassigned channels elsewhere, when the band was expanded to the full 20 MHz. Both New Zealand and the United Kingdom now have the standard global allocation of 88–108 MHz for FM. NZ permits Radio Data System subcarriers, but their adoption is not universal. Radio NZ uses RDS for its FM network, but commercial radio's adoption of the technology is not universal. The first station to broadcast on FM in New Zealand was a temporary station in Whakatane called FM 90.7.
She continued on convoy escort and patrol duty in the North Sea – having radar and radio telephone equipment installed in 1942 to improve her ability to detect German aircraft and small surface craft and give her a greater capability to warn other ships of the approach of enemy aircraft and ships and to communicate while manoeuvering – without further major incident until the surrender of Germany in early May 1945. She took no part in any operations related to the Allied invasion of Normandy in the summer of 1944. After Germanys surrender, Wolsey supported Allied forces reoccupying Norway, and on 14 May 1945 joined the destroyer in escorting minesweepers as they cleared the entrance to Stavanger.
B-Netz was an analog, commercial mobile radio telephone network that was operated by the Deutsche Bundespost in Germany (at first only West Germany) from 1972 until 1994. The system was also implemented in neighboring countries Austria, The Netherlands and Luxembourg. The B refers to the fact that it was the country's second public mobile telephone network, following the A-Netz. As opposed to its predecessor, it featured direct-dialing (so that human operators were not required to connect calls). The frequency plan originally included only 38 channels (with one call possible per frequency channel), but it was upgraded to incorporate the A-Netz frequencies when that network was retired in 1980.
Carl Menzer, whose interest in wireless began at his high school in Lone Tree, entered the State University of Iowa as a freshman in 1917, and later became station director for WHAA/WSUI, a position he held until his retirement in 1968. After the World War I moratorium on radio transmission was lifted in 1919, Menzer brought vacuum tube technology to 9YA, signaling the start of regularly scheduled voice and music broadcasts. The first “radio telephone” station, built using two donated experimental vacuum tubes, required use of two microphones for voice and for pickup of a windup phonograph. The microphones were swapped frequently when the one in use became too hot to touch due to high current.
Reeves joined the International Western Electric Company in 1923, and was part of a team of engineers responsible for the first commercial transatlantic telephone link. In 1925 Western Electric's European operations were acquired by ITT, and in 1927 Reeves was transferred to ITT's research laboratories in Paris. Whilst in Paris, he was responsible for a number of projects, including: a short-wave radio link between the telephone networks of Spain and South America, the world's first single-sideband radio telephone system, and for developing a multi-channel carrier system for UHF radio telephones. He was also responsible for innovations in the design of automatic frequency control circuits, digital delay lines and condenser microphones.
A Swiss rotary telephone dial from the 1970s, showing the telephone's number (94 29 68) along with those of various local emergency services Telephone numbers for sale in Hong Kong. The prices are higher for more desirable numbers. A telephone number is a sequence of digits assigned to a fixed-line telephone subscriber station connected to a telephone line or to a wireless electronic telephony device, such as a radio telephone or a mobile telephone, or to other devices for data transmission via the public switched telephone network (PSTN) or other public and private networks. A telephone number serves as an address for switching telephone calls using a system of destination code routing.
With the advent of VHF radio communication for shipping in the early 1960s, the need for signal stations was reduced, and following Wadsworth's retirement in December it was decided to close the Signal Station (the lighthouse which had been converted to automatic gas light in 1950, would continue to operate unattended). Wadsworth and his wife Jessie, had acquired land adjacent to the Signal Station in 1952. Following the closure of the Signal Station, the Wadsworths sought to acquire the use of part of the signal station building, and were granted an Informal Lease over the former Signal Station site in 1967. The Australian Telecommunications Commission (Telecom) removed the radio telephone equipment installed by the former PMG's Department, from the building in 1976.
Rather than selling products individually, a subscription offers periodic (monthly, yearly, or seasonal) use or access to a product or service, or, in the case of performance-oriented organizations such as opera companies, tickets to the entire run of some set number of (e.g., five to fifteen) scheduled performances for an entire season. Thus, a one-time sale of a product can become a recurring sale and can build brand loyalty. Industries that use this model include mail order book sales clubs and music sales clubs, private web mail providers, cable television, satellite television providers with pay television channels, providers with digital catalogs with downloadable music or eBooks, satellite radio, telephone companies, mobile network operators, internet providers, software publishers, websites (e.g.
The research-based origin of mesonets has led to the characteristic that mesonet stations tend to be modular and portable, able to be moved from one field program to another. Whether the mesonet is temporary or semi-permanent, each weather station is typically independent, drawing power from a battery and solar panels. An on- board computer takes readings from several instruments measuring temperature, humidity, wind speed & direction, and atmospheric pressure, as well as soil temperature and moisture, and other environmental variable deemed important to the mission of the mesonet, solar irradiance being a common non-meteorological parameter. The computer periodically saves these data to memory and transmits the observations to a base station via radio, telephone (wireless or landline), or satellite transmission.
On June 28, 1922, the Round Hills Radio Corporation was incorporated under a Massachusetts commercial charter, with Colonel Green as the company president. This initial charter stated that the company's function, in addition to engaging in radio broadcasting, was the sale of radio, telephone and similar equipment. Because the corporation did not actually engage in commercial activities, on August 15, 1923 it was rechartered under the state's charitable and educational statutes, with its mission now described as "for radio experimentation, improving the uses of wireless and scientific experimentation in new devices to further the use of radio, and to broadcast, free of charge, concerts, weather reports, etc."The Greens as I Knew Them by John Morgan Bullard, 1964, pages 28-29.
Martin Cooper photographed in 2007 with his 1973 handheld mobile phone prototypePrior to 1973, mobile telephony was limited to phones installed in cars and other vehicles. Motorola was the first company to produce a handheld mobile phone. On April 3, 1973, Martin Cooper, a Motorola researcher and executive, made the first mobile telephone call from handheld subscriber equipment, placing a call to Dr. Joel S. Engel of Bell Labs, his rival.Martin Cooper, et al., "Radio Telephone System", US Patent number 3,906,166; Filing date: 17 October 1973; Issue date: September 1975; Assignee Motorola The prototype handheld phone used by Dr. Cooper weighed and measured . The prototype offered a talk time of just 30 minutes and took 10 hours to re-charge.

Under the Bell System monopoly (post Communications Act of 1934), the Bell System owned the phones and did not allow interconnection, either of separate phones (or other terminal equipment) or of other networks; a popular saying was "Ma Bell has you by the calls". This began to change in the landmark case Hush-A-Phone v. United States [1956], which allowed some non-Bell owned equipment to be connected to the network, and was followed by a number of other cases, regulatory decisions, and legislation that led to the transformation of the American long distance telephone industry from a monopoly to a competitive business. This further changed in FCC's Carterfone decision in 1968, which required the Bell System companies to permit interconnection by radio- telephone operators.
Gunton served in the United States Army (1969–71) as a radio telephone operator with the 2nd Battalion, 501st Infantry Regiment of the 101st Airborne Division, and was assigned to Fire Support Base Ripcord atop a mountain in the A Sầu Valley during a 23-day siege. He and a comrade were awarded Bronze Star commendations for returning to the base to retrieve important but forgotten radios in the evacuation’s final moments so they would not fall into the hands of the North Vietnamese Army (NVA), which was about to capture the base, making him one of the last people to evacuate the base. During the battle, he lost one of his dog tags, but it was returned to him over 40 years later in 2018.
Lawrence Christopher Frank Horle (May 27, 1892 - October 29, 1950) was a noted American electrical engineer. Horle was born in Newark, New Jersey, and in 1914 received his degree in mechanical engineering from the Stevens Institute of Technology, where he served as instructor until 1916. From 1916-1917 he was a design engineer of the Public Service Corporation, Newark, and 1917-1920 served as an Expert Radio Aide in the United States Navy, supervising the radio development laboratory at the Washington Navy Yard. Horle was subsequently chief engineer of the de Forest Radio Telephone and Telegraph Company, New York; consultant, Department of Commerce Radio Laboratory, Bureau of Standards, Washington; chief engineer, Federal Telephone and Telegraph Company, New York; and vice-president, Federal Telephone Manufacturing Company, Buffalo.
Gherardi is widely recognized as one of the foremost authorities on early telephone engineering for his role in several landmark projects such as the transcontinental telephone service in 1915 and the trans-Atlantic radio telephone service in 1927. He also personally supervised the construction of a "loaded" cable between New York City and Newark, New Jersey, the first such application based on the invention of Michael I. Pupin that improved the transmission on telephone circuits. Gherardi was a fellow of the American Institute of Electrical Engineers, and served as its president from 1927 to 1928. He was a member of the United Engineering Society, American Society of Mechanical Engineers, American Standards Association, New York Electrical Society, and the Franklin Institute.
In April 1923, the De Forest Radio Telephone & Telegraph Company, which manufactured de Forest's Audions for commercial use, was sold to a group headed by Edward Jewett of Jewett-Paige Motors, which expanded the company's factory to cope with rising demand for radios. The sale also bought the services of de Forest, who was focusing his attention on newer innovations."DeForest Company Bought by Jewett", Radio Digest, April 21, 1923, page 2. De Forest's finances were badly hurt by the stock market crash of 1929, and research in mechanical television proved unprofitable. In 1934, he established a small shop to produce diathermy machines, and, in a 1942 interview, still hoped "to make at least one more great invention"."'Magnificent Failure'" by Samuel Lubell, Saturday Evening Post, January 31, 1942, page 49.
Vegas repairs were not completed until 14 November 1942. She emerged from them with Type 285 fire-control radar installed for her main guns, as well as a Type 286 air search radar to warn of the approach of aircraft. She returned to her convoy escort duties in the North Sea for the rest of World War II, and later had a Type 271 radar installed for the detection of submarines and motor torpedo boats. In 1943 she had radio telephone equipment installed to allow her to communicate with Royal Air Force aircraft during combat against German aircraft and S-boats (the motor torpedo boats known to the Allies as "E-boats"), as well as "Headache" (also known as "Y Outfit") radio receivers for the interception of E-boat communications.
The contingent was equipped with 24 De Havilland DH.4 aircraft, powered by American Liberty engines.Barnes, Alexander F., Coblenz 1919: The Army’s First Sustainment Center of Excellence, Army Sustainment, The Professional Bulletin of United States Army Sustainment, PB 700-10-05, Volume 42, Issue 05 In March 1921, Army Engineers had erected facilities on the airfield and the Americans were moved to the airfield from the temporary facilities they occupied in the town during the winter. Occupation duties included all sorts and types of flying, such as test flights, photos of radio telegraph and radio telephone missions, joint flights with infantry, cavalry and artillery units during the winter and spring maneuvers, cross country flights and passenger carrying. A significant amount of aerial photography was taken for cartographic missions, and large mosaics of photos were created.
C-Netz logo 1993 logo of the C-Netz, with the magenta Telekom logotype alongside the postal horn emblem then still in use. The telephone card symbol was often used alongside the C logo to indicate that the user card, a predecessor of the SIM card, could also be used as a standard telephone card in payphones. The Radio Telephone Network C (German: Funktelefonnetz-C, abbreviated as C-Netz), was a first generation analog cellular phone system deployed and operated in Germany (at first West Germany) by DeTeMobil (formerly of Deutsche Bundespost Telekom, currently Deutsche Telekom). It utilized the C450 standard, originally developed by Siemens AG, and was the third and last update of a series of analog mobile phone systems used primarily within Germany, superseding the B-Netz and the A-Netz before it.
For distant sites, a dry pair of telephone wires called a DC loop, private line- or RTO circuit (Radio Telephone Operation) was leased from the telephone company. Older burglar alarms used the same type of DC wiring from subscriber location to the alarm office. As pair gain electronics and point-to-point microwave radio links came into widespread use throughout the public switched telephone network, telephone companies filed tariffs to eliminate their past responsibility of providing leased circuits with direct current continuity. If the base station were located across town in an area served by a different telephone exchange, the only available circuits reaching the distant exchange might be a single voice-grade channel in a D-4 channel bank on a DS-1 or a single microwave radio baseband channel.
Procedure words or prowords are words or phrases limited to radio telephone procedure used to facilitate communication by conveying information in a condensed standard verbal format. Prowords are voice versions of the much older prosigns for Morse code first developed in the 1860s for Morse telegraphy, and their meaning is identical. The NATO communications manual ACP-125 contains the most formal and perhaps earliest modern (post-WW-II) glossary of procedure words, but its definitions have been adopted by many other organizations, including the United Nations Development Programme, the U.S. Coast Guard, the Rhode Island Department of Emergency Management, Civil Air Patrol, Military Auxiliary Radio System, and others. Procedure words are one of several structured parts of radio voice procedures, including Brevity codes and Plain language radio checks.
He also conducted research on ultra-short waves, electronics, and piezoelectric devices, and invented important modulation systems including the constant potential system, the grid modulation system, the rectifier modulation system used in carrier telephony, and the constant-current or Heising modulation system, which was standard on most early radio telephone transceivers. Heising held over 100 patents, including those on Class C amplifiers and diode-triode detector amplifier circuits, and was a Fellow of the American Institute of Electrical Engineers and American Physical Society. He was awarded the 1921 IEEE Morris N. Liebmann Memorial Award, the Modern Pioneer Award from the National Association of Manufacturers in 1940, an honorary Doctor of Science degree from the University of North Dakota in 1947, and the Radio Club of America's Armstrong Medal in 1954.
He agreed to accompany police to each of the burial sites to assist in the recovery of the victims. In one of the more dramatic moments in Houston television history, Jack Cato, a reporter for Houston's NBC television affiliate KPRC-TV, accompanied Henley and police as Henley led them to the storage shed where he and Corll had buried some of the murder victims' bodies. Cato allowed Henley the use of his mobile radio telephone to call Henley's mother, at which time Henley blurted the words, "Mama, I killed Dean" into the receiver, confessing to her that he had killed Dean Corll, all while Cato was capturing the conversation on film. The footage played several times on KPRC- TV's local news and was picked up for nationwide broadcast by NBC Nightly News that evening.
Such was the case for the brewing industry, foundries, flours and textiles, where machinery driven by steam, electric power or gasoline was worked on, which continued with an advanced technological level. The districts continued to be maintained but exclusively as districts with judicial functions, in October 1921 the Iturbide district changed its name to aragon In December 1923, the first radio-telephone station was installed that operated in the city, by agreement of the governor of the state, General Ignacio C. Enríquez and had the official record "XICE". At the same time, radio-receiver devices, which were popularly referred to as "radiolas", began to be installed in homes. On November 1, 1929, the first vitáfono or spoken cinema in the "Alcázar cinema" was adapted to the cinematographer, was with the film "The Jazz Singer".
59th Signal Battalion "Voice of the Arctic" The Alaska Communications System remained under the control of the Army Signal Corps until 1962 when it was taken over by the U.S. Air Force. The ACS handled the radioteletype, radio telephone, 500 kHz ship-to-shore frequencies, collected communications intelligence, and other services for more than half a century in Alaska. Records of the office of the Chief Signal Officer The Army Signal Corps (which develops, tests, provides, and manages communications and information systems support for the command and control of all the U.S. armed forces) connected military posts with each other and with the rest of the continental United States. This system of thousands of miles of suspended landlines and submarine cable included the first successful long-distance radio operation in the world.
Born in Lisse, Netherlands, Veldhuyzen van Zanten obtained his private pilot's licence on 21 June 1947, and his commercial pilot's licence on 18 April 1950. That year, he began working for KLM Royal Dutch Airlines as a flight director, and in 1951, he commenced duty as a first officer on the Douglas DC-3. He then obtained his Flight Radio Telephone Operator's Licence on 22 September 1952, Airline Transport Pilot's Licence on 19 October 1956, and Flight Navigator's Licence on 6 August 1963. On 23 January 1971, Veldhuyzen van Zanten was type-rated on the Boeing 747. That same year, he, along with two of his colleagues, went to Seattle to take delivery of KLM’s first 747, the Mississippi (registered PH-BUA). At the time of the disaster, he had 11,700 flight hours (1,545 of which were on the Boeing 747).
Carl Bildt. In response to the perceived failure of the Social Democrats to handle the economy and in protest over what was seen as outdated socialist policies (state-run monopolies in for example television, radio, telephone services & hospital care), newly formed reformist-populist party Ny demokrati made a successful surprise push for the Riksdag in the 1991 elections, enabling a new centre-right government to be formed. Under the leadership of Carl Bildt, the new government was determined to profile itself as anti-socialist and cosmopolitan, with the aim of initiating many reforms. Blaming some of the excesses of the Nordic model for the economic crisis, it wanted to initiate reforms and started dismantling of state-run monopolies, lowering of taxes, reshaping and internationalization of higher education, and laid the foundation for Sweden's subsequent entry into the European Union.
Subsequently, fire departments have also used them for this purpose, as well as for utility vehicles, radio command centers, canteens, and other secondary work. Police S.W.A.T. teams and other special units have used them as combined deployment and mobile command centers. An all-aluminum 1974 CM-Series International Harvester Metro Van P-40 painted black and lettered in white fitted with red takedown lamps and a siren speaker on its white roof was featured speeding to and famously skidding to halt at a crime scene for the 1975-76 police action title sequence of the TV series S.W.A.T. and was typically featured four or five times each episode to the show's theme song as the team was dispatched; running aboard, traveling in while utilizing the radio-telephone and jumping out of the Mobile Tactical Unit. Food trucks in Montreal.

Register Guard, November 16, 1953 In 1979, KUGN began airing some Mutual Broadcasting System programming, including Monday Night Football and Larry King's popular late night talk show. During its first four decades, KUGN was best known for its eclectic, personable announcers. The careers of such veterans as Duke Young, Dick Cross, Dave Miller, Russ Doran, Skip Hathaway, Webb Russell, Wendy Ray and Dale "Uncle Fuzzy" Reed spanned the period from the late 1950s to the early 1970s. The station had the first traffic reports in the market in 1976 when Ken Strobeck did morning and afternoon drive-time reports in the "KUGN Traffic Rabbit," a Volkswagen Rabbit equipped with a radio telephone and portable transmitter. Tom Lichty ("Major Tom") took over the job in late 1976 when traffic reporting took flight, serving both as traffic reporter and pilot.
Hand-marked statement During the flight back to Andrews Air Force Base, Johnson made several phone calls on the radio telephone, including to Rose Kennedy (JFK's mother) and Nellie Connally (wife of John Connally). In addition, he made the decision to request all cabinet members to stay in their posts and asked to meet both parties' leaders in Congress soon. Johnson also asked Jack Valenti, Bill Moyers, and Liz Carpenter to write a brief statement for him to read on the day's events, which he then edited slightly himself. At 6:10 pm, after landing at Andrews amid a crowd of Congressional leaders, he walked to an already prepared set of microphones and began his first public statement as president: Johnson had to raise his voice to be heard at the Air Force base, and afterward regretted delivering the remarks, believing he sounded harsh and strident.
Photo of Green's house, with the WMAF antenna in the foreground Colonel Green had an early fascination with radio technology, dating back to the 1890s. In June 1922, the Round Hills Radio Corporation was incorporated under a commercial charter, with Colonel Green the company president. Under the initial charter, the company's function, in addition to engaging in radio broadcasting, was to sell radio, telephone and similar equipment. However, because the company did not actually engage in commercial activities, in August of the next year it was rechartered under the state's charitable and educational statutes, with its mission now described as "for radio experimentation, improving the uses of wireless and scientific experimentation in new devices to further the use of radio, and to broadcast, free of charge, concerts, weather reports, etc."The Greens as I Knew Them by John Morgan Bullard, 1964, pp. 28-29.
In late 1919, de Forest had restarted an experimental radio station, 2XG (also known as "The Highbridge station"), at his laboratory in New York City, in order to promote the DeForest Radio Telephone and Telegraph company and showcase developments in vacuum-tube technology. Beginning in November 1919, that station had featured a nightly broadcast of news and entertainment. However, in early 1920 de Forest moved 2XG's transmitter from the Bronx to Manhattan without first getting permission from the government, and due to this infraction the local District Radio Inspector ordered him to suspend the station's operations.Father of Radio: The Autobiography of Lee de Forest, 1950, pages 349-351. De Forest's response was to ship 2XG's 500-watt transmitter from New York to San Francisco, where it was used to start a new station, also operating under an Experimental license, now with the call sign 6XC.

VC-25s used as Air Force One, flying over Mount Rushmore in February 2001. The United States Army uses fixed station call signs which begin with W, such as WAR, used by U.S. Army Headquarters. Tactical call signs are often assigned to a company sized unit or higher. For example, the collective "Checkmate" might be assigned to an entire company and thus "Checkmate Red 6" would be the first platoon leader (platoons are red for first, white for second, blue for third, black for headquarters, and often additional colors for other portions under the command), "Checkmate white 6" to the second platoon leader, etc. "Checkmate 6" is the Company Commander and "Checkmate 6 Romeo" is the commander's radio-telephone operator (Romeo the NATO phonetic of the letter R). Under some conventions, 6 is designated the commander or leader, 5 the second-in-command or executive officer, 7 the chief NCO.
Mr. Sarasohn worked at Raytheon Manufacturing Company in Waltham, MA, where he designed, built, and installed an experimental microwave radio transmission system for wideband general communication use. During World War II he worked at the MIT Radiation Lab and supervised the production of innovative radar systems for critical military applications. Mr. Sarasohn was 29 when General Douglas MacArthur summoned him to Tokyo to restore Japan's communications industry following its destruction during World War II. From 1946 through 1950, as chief of the Industry Branch of the occupation army's Civil Communications Section (CCS), Mr. Sarasohn took the lead in helping Japan rebuild its capacity to manufacture radio, telephone, and telegraph equipment—and to assure the reliable quality of its industrial production. Upon his return from Japan, Mr. Sarasohn worked as a management consultant with Booz, Allen & Hamilton in New York and later at IBM in several positions including Director of Engineering Communications.
Beginning in late 1912, radio communication in the United States was regulated by the Department of Commerce. Initially there were no formal standards for which stations could make broadcasts intended for the general public, and after World War One stations under a variety of license classes, most commonly Amateur and Experimental, began making regularly scheduled programs on a limited basis. In order to provide common standards for the service, the Commerce Department issued a regulation effective December 1, 1921 that stated that broadcasting stations would now have to hold a Limited Commercial license that authorized operation on two designated broadcasting wavelengths: 360 meters (833 kHz) for "entertainment", and 485 meters (619 kHz) for "market and weather reports"."Amendments to Regulations", Radio Service Bulletin, January 3, 1922, page 10. On December 20, 1921 a broadcasting station license with the randomly assigned call letters KYY was issued to The Radio Telephone Shop, for operation on 360 meters."New Stations", Radio Service Bulletin, January 3, 1922, page 2.
The Funkhorchdienst (signals intelligence service, General Wolfgang Martini) attempted to jam British radio-telephone frequencies by using a technique to increase atmospheric interference to reduce the performance of British coastal radars. Dornier Do 217s of Kampfgeschwader 2 (Bomber Wing 2) were to fly electronic deception sorties over the western Channel to divert British aircraft. Fliegerkorps IX (General der Flieger [Luftwaffe General] Joachim Coeler) prepared to bomb RAF bases in south-west England and to attack and distract British naval forces attempting to intercept the Brest Group. Fernaufklärungsgruppe 123 (Long-range Reconnaissance Group 123) was to keep watch on both ends of the Channel and support Fliegerkorps IX. The convoy route was divided into three sectors using the Jafü (Fighter Sector) boundaries but to ensure local control Max Ibel, the former commander of Jagdgeschwader 27 (Fighter Wing 27) was appointed Jagdfliegerführer Schiff (Jafü Schiff, Fighter Controller: Ship) and embarked onto Scharnhorst as a signals officer to communicate with Luftwaffe units during the operation.
Tactical information from Enigma was not well co- ordinated with RAF Y-stations (RAF Y), which reported separate to Enigma but RAF Y was able to give warnings of German sightings of coastal convoys and imminent attacks, by eavesdropping on and decrypting wireless transmissions between aircraft and the ground. RAF Y identified airborne bomber units and their bases, occasionally also uncovering the target area, although it was mid-August before this added much to RDF reports. German voice transmissions by radio telephone (R/T) were collected by stations around Britain based on RAF Kingsdown in Kent by German speaking WAAF and WRNS and sent to local RAF headquarters and Fighter Command HQ, the centre of the Dowding system where they were collated with reports from RDF and the Observer Corps. Voice transmissions could occasionally alert Fighter Command to formations assembling beyond RDF range, give the height of formations, discriminate between fighters and bombers and hear orders being passed to fighter escorts showing main and secondary attacks, judgements about RAF intentions, meeting points and courses for return journeys.
Although KDN was first licensed as a broadcasting station in late 1921, this was actually a relicensing and continuation of operations begun under an Experimental license, 6XG,"New Stations: Special Land Stations", Radio Service Bulletin, June 1, 1921, page 3. The "6" in 6XG's call sign indicated that the station was located in the sixth Radio Inspection district, while the "X" meant that it was operating under an Experimental license. issued to the Leo J. Meyberg Company a few months earlier. The Meyberg company was an electrical parts distributor with offices in San Francisco and Los Angeles that boasted it had "the largest radio stock of the Pacific coast". 6XG was the first of two stations established by Meyberg for providing a broadcasting service, as later that year the company began operating 6XAK (later KZC/KOG) from the Hamburger's department store in Los Angeles.Leo J. Meyberg Co. (advertisement), Radio magazine, December 1921, page 218. 6XG inaugurated regular programming in June, transmitting from the Fairmont Hotel on Nob Hill in San Francisco, using a wavelength of 350 meters (857 kHz) and initially employing a 10 watt transmitter."6XG—The Fairmont Radio Telephone", Pacific Radio News, July 1921, pages 411, 433.
According to a 1970s-era Central Locator System handbook, each person in the line of succession was assigned a codename with which he or she could identify themselves to the Central Locator (for instance, the codename assigned to United States Senate president pro tempore James Eastland was "FOURFINGER", while then United States Secretary of the Treasury George Shultz was given the codename "FENCING MASTER"). Individuals tracked by the system were required to provide multiple means of contact – including physical addresses, and home, office and mobile radio telephone numbers – and to notify the Central Locator any time they left the city of Washington, D.C., providing their itinerary and places of residence while traveling. During a national emergency, tracked persons were instructed to contact the Central Locator using either landline phone or the Defense Communications System and provide details on their exact whereabouts. In the event of a mass call event that prevented persons in the line of succession from reporting their location to the Central Locator, they were authorized to call the telephone operator and use the message precedence order "FLASH" to override other line traffic and force through a call.
The receiving station's control centre and radio masts were located at Highbridge, near Burnham-on-Sea. The radio station played a vital role during the Second World War in maintaining communications with the British merchant navy and with patrol aircraft in the North Atlantic. During the war, all communications with ships were one-way in order to avoid revealing the ships' locations to the enemy. The station was short-staffed because many were on secondments to various government services, such as operating other radio stations and training new radio officers to work in naval convoys. In 1943, the workload was so great that a Royal Navy officer and 18 telegraphists were brought in from HMS Flowerdown, a Naval Shore Wireless Service station near Winchester. By the end of the 1980s, satellite communications had started to take an increasing share of the station's business, and a programme of severe rationalisation began, leading to the closure of two transmitting sites at Leafield and Ongar. In the radio station's penultimate year to March 1999, there were on average, per month, 571 radio telegrams, 533 radio telephone calls and 4,001 radio telex calls. In 1998, British Telecom Maritime Radio Services announced its planned closure of Portishead Radio.
Overall, the living quarters were considerably smaller than those of Crowhurst's competition. For communication, Crowhurst had a Marconi Kestrel radio-telephone, a Racal RA 6217 communications receiver, a Shannon Mar 3 transmitter/receiver, headsets, Morse keys, switch panels, and gross amounts of radio spares. Powering the electronics on the boat was an Onan petrol-driven generator that was seated under the cockpit where it would be at risk of continuous exposure to water in rough weather. The galley consisted of a small burner, a pot and sink with freshwater supplied from 8 Plysu containers holding part of his water supply which were connected to four large fixed water tanks, mounted inside the port and starboard side floats. The typical “Victress” cabin also featured built-in cabinetry; Crowhurst allowed a few units of shelving in the galley, but replaced most of it with lightweight Tupperware plastic containers for storing food, electronic components and a second-hand Bell and Howell 16mm camera and Uher tape recorder that had been provided by the BBC for documenting the journey. Crowhurst brought aboard only 5 books: Albert Einstein’s Relativity, the Special and the General Theory; Shanties from the Seven Seas; Servomechanisms; The Gypsy Moth Circles the World; and Mathematics of Engineering Systems.
