The club obtained a Special Events Station Licence to activate the use of the Cornish Mine as an amateur radio station. Also in 2016 Eagle Plant opened an accommodation hire business on the site followed in February 2017 by a Plant Hire operation.

" Toronto Star, August 22, 1936, p. 11. Around that time, he got the idea for a radio amateur hour, similar to those already on the air in the United States, such as the one hosted by Major Bowes. Ken Soble's Amateur Hour was first broadcast on CKCL in Toronto, but he was soon able to expand it to a regional network; ultimately, it aired across Canada and became one of the country's most popular programs, even though, by his own admission, the show was "corny." "Ken Soble: He favored Anything That Worked.

On January 20, 2018 IMAGE was found by Canadian radio amateur and satellite tracker Scott Tilley to be broadcasting, and he reported it to NASA. He had been scanning the S-band (microwaves) in the hopes of finding the Zuma satellite. On January 24, 2018 Richard Burley of NASA reported that they were trying to establish communication with the satellite using the NASA Deep Space Network. Two days later, Burley reported that engineers at Goddard Space Flight Center successfully acquired the signal, and confirmed on January 30, 2018 that IMAGE is the source.

Radio amateurs have been early in arranging relay leagues, as is reflected in the name of the organization of American Radio Relay League (ARRL). Radio amateur message relay operations were originally conducted in the first two decades of the 20th century using Morse code via spark-gap transmitters. As vacuum tubes became affordable, operations shifted to more efficient manual telegraphy transmitters, referred to as CW (Continuous wave). Messages were relayed station-to-station, typically involving four or more re-transmission cycles to cover the continental United States, in an organized system of amateur radio networks.

From its inception in 1913 until the end of 1924, the official journal of the Radio Society of Great Britain was the independent publication Wireless World and Radio Review. Due to a change in proprietorship of that magazine, the honour was withdrawn and bestowed instead on Experimental Wireless and the Wireless Engineer. In July 1925, it was decided by members of the Society's Transmitting and Receiving (T & R) Section to produce its own monthly publication "written by and for the radio amateur". This was entitled T & R Bulletin.

Subpart E contains four sections, numbered 97.401–407. Subpart E supports the service of amateur radio operators in times of disaster by establishing basic standard operating procedures to use in case an emergency should occur. Primarily, it authorizes any use of radio technology for the "immediate safety of human life and immediate protection of property," regardless of all other FCC regulations, when no alternative is available. It also establishes the Radio Amateur Civil Emergency Service (RACES), a civil defense communications service intended for activation in times of war or threat to national security.

He was also a ham-radio (amateur radio) operator, with the call letters W6VH, and he was a charter member of the Pacific Pioneer Broadcasters, the Society of Wireless Pioneers and the Radio Club of America. In 1973 he returned to the City Hall to fight a request by Santa Monica Mountains homeowners to curb "unsightly aerials" of amateur radio operators on hillside rooftops that interfered with the view from expensive lots. Brown said that ham operators had provided valuable communication links in disasters like the Sylmar earthquake and floods. A city council committee rejected any further control.

Perhaps the most commonly used intermediate frequencies for broadcast receivers are around 455 kHz for AM receivers and 10.7 MHz for FM receivers. In special purpose receivers other frequencies can be used. A dual-conversion receiver may have two intermediate frequencies, a higher one to improve image rejection and a second, lower one, for desired selectivity. A first intermediate frequency may even be higher than the input signal, so that all undesired responses can be easily filtered out by a fixed-tuned RF stage.Wes Hayward, Doug De Maw (ed),Solid state design for the radio amateur, (American Radio Relay League, 1977) pp.

The down-link will be on the 70 cm amateur radio band (437 MHz - referring to the 70 cm band plan). On the down-link data frequency we will be able to send packet data, SSTV still picture images, Morse code and maybe some short voice messages. The Morse code transmission is elementary necessary for receiving the status directly after the deployment out of the launch pod, recovering the satellite and long time health measurement of the satellite. Nearly every radio amateur is familiar to Morse code, so it is possible to get telemetry from every part of the world.

By 1952 the GOC program was expanded into Operation Skywatch, consisting of 750,000 volunteers aged 7 to 86 years old working in shifts at over 16,000 posts and 73 filter centers. Extant examples of observation platforms used by GOC/Skywatch volunteers include the Cairo Skywatch Tower; Note: This includes and Accompanying photographs another tower exists in Soda Springs, Idaho. The second GOC program ended in 1958 with the advent of automated Army (Missile Master) and Air Force (SAGE) radar systems. GOC volunteers were encouraged to continue their service in the Radio Amateur Civil Emergency Service (RACES).

Aboard the schooner "Blue Bird" traveling on the Adriatic are schoolchildren, winners of the questionnaire "For Peace and Mutual Understanding". Taking advantage of the fact that the ship, when entering the ports, is released from customs inspection, an international gang organizes the delivery of a consignment of drugs. Mrs. Rips, an observer from the Society for the Patronage of Animals and her companion, the circus Lorimur act as couriers. A radio amateur from the US, schoolboy Ralph and his Yugoslav friend, Milan, consider the behavior of Monsieur Vilar, the pediatrician attached to the expedition, as very strange.

Marshall D. Moran was born in Chicago on May 29, 1906 and died April 14, 1992 in Delhi, India. He was an American Jesuit priest, missionary in India and Nepal where he founded several schools, amongst them the St. Xavier's High School, Patna and the Godavari St. Xavier's school of Kathmandu. He also was an active radio amateur and used the call sign 9N1MM, pioneering amateur radio in Nepal. This location made him one of the most well-known Radio Amateurs of his time, described and visited many times by American and European Ham Radio magazines.

The Dutch Amateur Radio Emergency Service (DARES) was founded in 2003 as a result of the World Radio Conference 2003, where it was decided that licensed Dutch radio amateurs were allowed to offer their services to third parties when there is an emergency. DARES is recognized by the State Department of The Netherlands and supported by the two largest national radio amateur organisations: VERON and VRZA. DARES consists of a group of radio amateurs and shortwave listeners who offer their knowledge and radio equipment during a disaster or major incident. The organisation is built upon the 25 safety regions defined by Dutch authorities.

Ben Nock has been a Radio Amateur since the late 1960s and started in the hobby, as many did in those days, using surplus radio equipment from the second world war. After years of simply playing with the hobby there came a turning point in the 1980s when the thought of collecting this equipment for future preservation occurred and the process of collecting was begun. After 20 years the collection has grown to around 900 sets and countless additional items of military hardware. The Virtual Museum web site was conceived in the late 1990s and the site is expanded daily.

At the German attack on Norway in April 1940 Jahn Dahm was a nineteen-year-old engineering student at Bergens Tekniske Skole. He had been an eager radio amateur and a member of Bergen Radio Relé Liga for years, and at home he also had a workshop for building radios. On 25 June 1940, while he had an examination at the school, he was taken to the Gestapo office in Bergen, where he was confronted with equipment taken from his home and told he would be charged with espionage. On 28 June he was transported by bus from Bergen to Møllergaten 19 in Oslo with ten other arrestees.

Large national or international events will have one day of competition using a 2-meter frequency and one day of competition using an 80-meter frequency. In addition to the rules of the sport, ARDF competitions must also comply with radio regulations. Because the transmitters operate on frequencies assigned to the Amateur Radio Service, a radio amateur with a license that is valid for the country in which the competition is taking place must be present and responsible for their operation. Individual competitors, however, are generally not required to have amateur radio licences, as the use of simple handheld radio receivers does not typically require a license.

""Local Commercial Station Delayed", "The Radio Amateur" by C. E. Urban, Pittsburgh Gazette Times, November 23, 1919, Sixth section, page 2. In late January 1920, it was announced that "The latest type of radiophone, developed and produced in the laboratory of Dr. Lee de Forest at New York, has just been installed in the downtown store of the Doubleday- Hill Electric Company. Arrangements have been made by this company with a local music store to furnish the latest phonograph records weekly for use in connection with wireless concerts to be given on a regular schedule. This schedule has not been definitely fixed, but will be announced in a short time.

In September 1921, it was announced that Doubleday-Hill was planning to install a high-powered station, which again was planned to be used primarily for two-way communication with a second proposed station located at its Washington, D.C. store. In addition, it was stated that the new station would "be used to give entertaining programs for amateur reception on certain evenings of each week"."The Radio Amateur" by C. E. Urban, Pittsburgh Gazette Times, September 11, 1921, Sixth section, page 7. In October 1921 this new station was issued a Limited Commercial license, transmitting on 200 and 425 meters (1500 and 706 kHz), with the call letters KQV.

Beginning on 1 May 1978, the Canadian authorities allowed radio amateurs on the 1.25-meter band (220 MHz) to use packet radio, and later in 1978 announced the "Amateur Digital Radio Operator's Certificate". Discussion on digital communication amateur radio modes, using the internet protocol suite and IPv4 addresses followed subsequently. By 1988, one thousand assignments of address space had been made. approximately 1% of inbound traffic volume to the network was legitimate radio amateur traffic that could be routed onwards, with the remaining 2‒100 gigabyte per day of Internet background noise being diverted and logged by the University of California San Diego (UCSD) internet telescope for research purposes.

Radio observatories are preferentially located far from major centers of population to avoid electromagnetic interference (EMI) from radio, television, radar, motor vehicles, and other man-made electronic devices. Radio waves from space were first detected by engineer Karl Guthe Jansky in 1932 at Bell Telephone Laboratories in Holmdel, New Jersey using an antenna built to study noise in radio receivers. The first purpose-built radio telescope was a 9-meter parabolic dish constructed by radio amateur Grote Reber in his back yard in Wheaton, Illinois in 1937. The sky survey he did with it is often considered the beginning of the field of radio astronomy.

Perhaps the first to take advantage of the lifting of the civilian station restrictions was a Westinghouse engineer, Frank Conrad, who had worked on radio communication contracts during the war. On the evening of October 17, 1919 he made the first of what would ultimately become a twice- weekly series of programs, broadcast from his home in Wilkinsburg, Pennsylvania over experimental station 8XK."The Radio Amateur" by C. E. Urban, "Wireless Telephone Here", Pittsburgh Gazette Times, October 26, 1919, Sixth section, page 13. Beginning in early 1920 the Precision Equipment Company, a small radio retailer in Cincinnati, Ohio, used a homemade transmitter to make occasional broadcasts over its experimental station, 8XB.

Above that at 150 m (492 ft) is the operations platform housing the workforce and equipment, and further up six differentially sized, smaller open platforms in same distances, populated with high-gain directional microwave radio relay antennas ("parabolic mirrors"). Number nine was added at 25 m height in July 2005.346x346px After the observation platform and restaurant were closed due to asbestos decontamination, former stuntman Jochen Schweizer had a bungee jumping base installed. The restaurant will not open again due to new fire escape regulations, and the bungee platform was closed at the end of 2001. The tower has been home to the VFDB Hamburg section's radio amateur club station "DF0HHT".

The first DX cluster software, PacketCluster was realized by US radio amateur Dick Newell, AK1A in the late 1980s, and quickly became popular as a means of exchanging DX-related information. Before the internet became widely available, the nodes running the cluster software would connect via radio links at certain frequencies allocated within the amateur radio bands. Users of the system would then connect to a node using frequencies different from those used by the nodes. When the internet became widely available, the system was expanded to make use of telnet connections to internet nodes, in addition to the already established packet radio nodes.

This communication method is variable and unreliable, with reception over a given path depending on time of day or night, the seasons, weather, and the 11-year sunspot cycle. During the first half of the 20th century it was widely used for transoceanic telephone and telegraph service, and business and diplomatic communication. Due to its relative unreliability, shortwave radio communication has been mostly abandoned by the telecommunications industry, though it remains important for high-latitude communication where satellite-based radio communication is not possible. Some broadcasting stations and automated services still use shortwave radio frequencies, as do radio amateur hobbyists for private recreational contacts.

15, 2008. The concept of a standby "Radio Amateur Civil Emergency Service" to replace the conventional "Amateur Radio Service" during wartime was developed in 1952 as result of input from the American Radio Relay League and the Department of the Army's Office of Civil Defense. During World War II, the Amateur Radio Service had been silenced and a new War Emergency Radio Service (WERS) had to be created from scratch in a process that took six months. The resulting standby RACES service was designed to provide a quicker and smoother transition in the event the President ever needed to silence the regular Amateur Radio Service again when invoking the War Powers Act of 1941.

AMSAT-OSCAR 7, or AO-7, is the second Phase 2 amateur radio satellite constructed by the Radio Amateur Satellite Corporation or AMSAT. It was launched into Low Earth Orbit on November 15, 1974 and remained operational until a battery failure in 1981. Then after 21 years of apparent silence, the satellite was heard again on June 21, 2002 – 27 years after launch. At that time the public learned that the satellite had remained intermittently functional and was used surreptitiously for communication by the anticommunist opposition Fighting Solidarity during the martial law in Poland. AO-7 is the oldest amateur satellite still in use, and is one of the oldest operational communications satellites.

The equipment was constructed for the most part in the Electrical Engineering laboratory by the radio amateur students interested in the station and with the help and guidance of the head of the Electrical Engineering Department, Dean F. C. Bolton who later became President of the College. The main power transformer had been constructed for oil testing purposes and was capable of providing the power limit of two kilowatts allowable under the special experimental license of 5XB. The transmitting condenser consisted of about 100 clear glass photographic plates interlaced with tinfoil from damaged paper condensers from the laboratory. The entire "sandwich" of glass plates and tinfoil was immersed in an oil-filled copper-lined box.

"The First Wireless Time Signal" (letter from Captain J. L. Jayne), Electrician and Mechanic, January 1913, page 52. (Reprinted from The American Jeweler, October 1912, page 411.) In Europe, signals transmitted from a station located on the Eiffel tower were received throughout much of Europe. In both the United States and France this led to a small market of receiver lines designed geared for jewelers who needed accurate time to set their clocks, including the Ondophone in France,"Vest-Pocket Wireless Receiving Instrument", Electrical Review and Western Electrician, April 11, 1914, page 745. and the De Forest RS-100 Jewelers Time Receiver in the United States"Radio Apparatus" (advertisement), Radio Amateur News, October 1919, page 200.

It was captioned "The Radio Detective Who Unfathomed the Famous 'Nauen Buzz'" and the description read: > During the early days of the World War the incredibly rapid and > undecipherable radio signals between the most powerful broadcasting station > in Germany and the station of the "Telefunken Company" at Sayville, Long > Island, N.

The American Radio Relay League is a non-commercial membership association of amateur radio operators organized for the promotion of interest in Amateur Radio communication and experimentation, for the establishment of networks to provide communications in the event of disasters or other emergencies, for the advancement of the public welfare, for the representation of the Radio Amateur in legislative and regulatory matters. ARRL is the principal organization representing the interests of the more than 650,000 U.S. Radio Amateurs. Because of its organized emergency communications capability, ARRL's Amateur Radio Emergency Service (ARES) can be of valuable assistance in providing critical and essential communications during emergencies and disasters when normal lines of communication are disrupted. ARRL conducts emergency communications training and certifies proficiency in emergency communications skills.

Although it would gain its fame as a broadcasting station, KDKA actually originated as part of a project to establish private radiotelegraph links between Westinghouse's East Pittsburgh factory and its other facilities, to avoid the business expense of paying for telegraph and telephone lines. In September 1920, a newspaper report noted that "a new high-power station, to operate under a special or commercial license, is being installed at the Westinghouse plant in East Pittsburgh. It will be used to establish communication between the East Pittsburgh plant and the company branch factories at Cleveland, O., Newark, N. J., and Springfield, Mass., where similar outfits will be employed."The Radio Amateur by C. E. Urban, Pittsburgh Gazette Times, September 26, 1920, Fifth section, page 10.

In the days before the arrival of the American army, thousands of the prisoners were forced to join the evacuation marches. Thanks in large part to the efforts of Polish engineer (and short-wave radio-amateur, his pre- war callsign was SP2BD) Gwidon Damazyn, an inmate since March 1941, a secret short-wave transmitter and small generator were built and hidden in the prisoners' movie room. On April 8 at noon, Damazyn and Russian prisoner Konstantin Ivanovich Leonov sent the Morse code message prepared by leaders of the prisoners' underground resistance (supposedly Walter Bartel and Harry Kuhn): The text was repeated several times in English, German, and Russian. Damazyn sent the English and German transmissions, while Leonov sent the Russian version.

Jamboree on the Air, usually referred to as JOTA, is an international Scouting and Guiding activity held annually on the third full weekend in October. The event was first held in conjunction with the fiftieth anniversary of Scouting in 1957, and was devised by radio amateur operator Leslie R. Mitchell who used the callsign G3BHK. It is now considered the largest event organized by the WOSM annually. Scouts talking on the radio during Jamboree On The Air Amateur radio operators from all over the world participate with over 500,000 Scouts and Guides to teach them about radio and to assist them to contact their fellow Scouts and Guides by means of amateur radio and since 2004, by the VOIP-based Echolink.

There are claims that, as the Kido Butai (the Striking Force) steamed toward Hawaii, radio signals were detected that alerted U.S. intelligence to the imminent attack. For instance, the Matson liner , heading from San Francisco to Hawaii on its regular route, is said to have heard and plotted, via "relative bearings", unusual radio traffic in a telegraphic code very different from International MorseThe ARRL Handbook for the Radio Amateur, American Radio Relay League, Newington, CT. which persisted for several days, and came from signal source(s) moving in an easterly direction, not from shore stations—possibly the approaching Japanese fleet. There are numerous Morse Code standards including those for Japanese, Korean, Arabic, Hebrew, Russian, and Greek. To the experienced radio operator, each has a unique and identifiable pattern.

An Anderson Powerpole Powerpole connectors are a series of connectors developed by Anderson Power Products Anderson Power Products Powerpole® Connector Series and are available in a variety of sizes and colors. The commonly used 15/30/45 series connectors are interoperable with each other and use the same housings but use different contacts for different wire sizes and current requirements. Powerpole connectors are physically and electrically genderless, thus avoiding the need to worry about which end is the plug and which the socket, or which end has the correct polarity, as is the case with the physically but not electrically genderless 2-wire trailer plug. Powerpoles have been adopted as a standard 12 VDC connector by most RACES Radio Amateur Civil Emergency Service organizations and ARES Amateur Radio Emergency Service units.

Robert B. Dome (October 12, 1905 - January 18, 1996) was an American electrical engineer credited with inventing frequency interlace color television modulation, which was compatible with existing black and white television sets. Dome received his BSEE in 1926 from Purdue University, and worked for General Electric in Syracuse, New York. He also invented techniques for audio transmission, and received the 1951 IEEE Morris N. Liebmann Memorial Award "for many technical contributions to the profession, but notably his contributions to the inter-carrier sound system of television reception, wide band phase shift networks, and various simplifying innovations in FM receiver circuits." He was also a licensed radio amateur and a respected technical contributor to that community as W2WAM and may have held other call signs at other times (help needed).

U.S. Naval Radio Station Otter Cliffs was a United States Navy radio receiver facility located in Acadia National Park on Mount Desert Island, south of Bar Harbor, Maine. The station was commissioned on August 28, 1917, under the command of Lt. Alessandro Fabbri, who had personally cleared the land, built and equipped the station, and offered it to the government in exchange for a commission in the Naval Reserve and assignment as Officer-in-Charge. Prior to the war, Fabbri was a licensed radio amateur with the U.S. Government issued call sign 1AJ. Otter Cliffs was the Navy's best transatlantic radio receiver site because of its absence of nearby man-made radio noise, its unobstructed ocean path from Europe, and the outstanding receivers, antennas and noise mitigation techniques developed by the Wireless Specialty Apparatus Company under the leadership of Greenleaf Whittier Pickard.

At the age of 18, Travis performed "Tiger Rag" on a local radio amateur show in Evansville, Indiana, leading to offers of work with local bands. In 1937 Travis was hired by fiddler Clayton McMichen as guitarist in his Georgia Wildcats. He later joined the Drifting Pioneers, a Chicago-area gospel quartet that moved to WLW radio in Cincinnati, the major country music station north of Nashville. Travis' style amazed everyone at WLW and he became a popular member of their barn dance radio show the "Boone County Jamboree" when it began in 1938. He performed on various weekday programs, often working with other WLW acts including Louis Marshall "Grandpa" Jones, the Delmore Brothers, (in Alton Delmore's book "Truth is Stranger Than Publicity" on pages 274–275, Alton describes how he taught Merle Travis how to read and write music)Truth is Stranger Than Publicity 1995 ed.

Together with Dr. Alexandru Savopol, October 26, 1926, Second Lieutenant Ioan T. Băjenescu produced the first radio program in Romania for the general public; the program was heard throughout the territory of Oltenia and many echoes appeared in the press in all the cities of Oltenia, and even of the Timok Valley (Bulgaria). The mother, Lelia Constanţa (born May 21, 1908, Corlate, Romania; deceased December 15, 1980, Craiova, Romania), born Petrescu, was the first radio amateur woman in Romania, using her husband's call-sign YL CV5BI. Fluent in French and German, she established tens of thousands of radio links on all meridians. Unfortunately, of these QSL (which have been collected over the years as evidence of these radio links) there remains almost nothing, since, immediately after the establishment of the communist regime, they were all burned, as they were evidence of "links with enemies" outside the country.

"The Radio Amateur" by C. E. Urban, "Wireless Telephone Here", Pittsburgh Gazette Times, October 26, 1919, Sixth section, page 13. During this time the Joseph Horne department store ran daily full-page advertisements in the Pittsburgh papers, and, in its September 23, 1920 placement, stated that the store had started selling "Amateur Wireless Sets" for "$10 upwards"."The Horne Daily News" (advertisement), Pittsburgh Press, September 23, 1920, page 13. Six days later, the store's September 29 installment included a small notice titled "Air Concert 'Picked Up' By Radio Here", which noted that its demonstration set had been used to receive one of the Conrad broadcasts."The Horne Daily News" (advertisement), Pittsburgh Press, September 29, 1920, page 11. H. P. Davis saw this advertisement and immediately recognized the "limitless opportunity" of adding radio receivers to the lines of appliances sold to the general public by Westinghouse,"Pittsburgh's Contributions to Radio" by S. M. Kintner, Proceedings of the Institute of Radio Engineers, December 1932, pages 1849-1862.

Effective October 1, 1919, the ban on civilian radio stations was lifted. Although his station would not be formally relicensed until January 21, 1921,Experimental License number 236, call sign 8XK, covering January 21, 1920-January 20, 1921. Conrad resumed experimenting, again using the 8XK callsign,Presumably Conrad had been given an informal authorization to operate pending the license reissuance. "Getting Your Licenses" (QST, November 1919, page 12) noted that "Radio Inspectors are authorized, however, to advise applicants what call letters they will eventually receive on their licenses and authorize them to commence operation at once, using their official call, without awaiting receipt of the actual license." and now also testing vacuum- tube radiotelephone equipment. Conrad's experimental radio station, 8XK, was located in his home's garage. He was responsible for one of the country's first post-war radio broadcasts, when, on the evening of October 17, 1919,"The Radio Amateur" by C. E. Urban, "Wireless Telephone Here", Pittsburgh Gazette Times, October 26, 1919, Sixth section, page 13.

The Victorian ARDF Group, a regional ARDF organization in Australia, uses the two-word form of the term radio sport in its logo. Radiosport also can refer to the sport of amateur radio direction finding (ARDF). Although they represent a broad range of amateur radio interests in their nations today, several member societies of the International Amateur Radio Union were originally formed for the promotion and organization of the sport of ARDF and continue to use the term radiosport in their society name. These include the Radio Sport Federation of Armenia, the Belarusian Federation of Radioamateurs and Radiosportsmen, the Chinese Radio Sports Association, the Kazakhstan Federation of Radiosport and Radio Amateur, the Mongolian Radio Sport Federation, All-Russian public radiosport and radioamateur organization «Soyuz Radiolyubiteley Rossii»,Complete name of Russian Amateur Radio Union – SRR, following official charter Ukrainian League of Radio amateurs and the now defunct Radio Sport Federation of the USSR.

In the 1960s, Geoffrey Perry, head of the school Physics department experimented with using satellite signals and the Doppler effect as an aid to teaching. The activity soon grew into regular monitoring of Soviet launched satellites and expanded into an international collaboration that became known as the Kettering Group. The group was headed by Geoffrey Perry, who by then had become Head of Science Teaching. On the technical front Geoff was partnered by the head of the Chemistry department, Derek Slater - a Radio Amateur, G3FOZ.Cytringainian Farewell, Kettering Grammar/Boys School (1577–1993) Work of the group involved tracking satellites with radios, and eavesdropping on communications to cosmonauts, as well as analysing orbits in an attempt to identify different subsets. In 1966, the fledgling group discovered the location of a new secret Soviet launch station in north Russia, Plesetsk, before the American military or intelligence services had released details. In 1957 Aviation Week magazine revealed that the U.S. had been tracking Russian missile launches from advanced long-range radar units in Turkey. The article caused a furore, with President Dwight D. Eisenhower's special assistant for National Security Affairs, Robert Cutler, referring to the article as "treasonable".

WSAJ's founder, Dr. Herbert W. Harmon"A Practical Radiophone for the Amateur" by Herbert W. Harmon, Radio Amateur News, May 1920, pages 616-618. Radio research at Grove City College, primarily under the oversight of physics professor Dr. Herbert W. Harmon, dated to at least 1914, when Harmon and the school were jointly issued a license for a standard amateur station with the callsign 8CO."Amateur Stations—Eighth District", Radio Stations of the United States: Edition July 1, 1915, page 140. (The "8" in 8CO's callsign indicated that the station was located in the eighth Radio Inspection District). In early 1917 the college received a Technical and Training School license, with the callsign 8YV."Special Land Stations", Radio Service Bulletin, March 1, 1917, page 3. (The "Y" in 8YV's callsign indicated that the station was operating under a "Technical and Training School" license.) Like most radio stations at this time, the College's stations used spark transmitters, so they could only be used for Morse code communication. In addition, on April 6, 1917 all civilian radio stations were ordered to shut down, due to the start of World War One. Effective October 1, 1919, the ban on civilian radio stations was lifted, and 8YV was reactivated.
