Clarence Denton "C. D." Tuska (August 15, 1896 – June 30, 1985) was an early radio experimenter and amateur operator who also became one of the first radio receiver manufacturers. He is best known as the co-founder of the American Radio Relay League (ARRL), along with Hiram Percy Maxim. He was also the original editor and owner of the amateur radio publication QST, which he subsequently sold to the ARRL in 1919 as part of his reorientation toward professional activities within the radio industry.

Early life

Tuska was born in New York city, the only child of Ida Anna Ruddell and David Tuska. He lived in Nyack, New York until 1909, when his family moved to Hartford, Connecticut. After graduating from high school, he attended the local Trinity College (class of 1919), although he did not receive his Bachelor of Science degree until 1939.

Amateur radio activities

Tuska had an early interest in radio communication (then known as "wireless telegraphy") and experimentation. While living in Nyack in 1908, a New York City cousin helped him construct a small radio transmitter, and he constructed progressively more powerful stations after moving to Hartford the next year. Radio transmitters in the United States were not licensed at this time, so he initially operated using the self-assigned call letters SNT, which stood for "Southern New England-Tuska".

Tuska began earning pocket money around 1910, while in the ninth grade, by selling rubber band-powered model airplanes on consignment through the Harris Parker Toy Store. After these sales started to decline, he constructed a simple crystal radio receiver, also offered through consignment at the toy store. Inventor Hiram Percy Maxim took this set home to test, but soon returned it, and the store owner incorrectly informed Tuska that Maxim had said that it didn't work. This upset Tuska, so he travelled unannounced to Maxim's house with friend William Ball to investigate. Maxim clarified that he actually just needed better quality equipment, so Tuska and Ball arranged for ordering the appropriate components which were used to construct a set that "gave satisfactory service for a number of years". Both Maxim and Tuska became prominent local amateur radio enthusiasts, with the two forming an informal "father-foster-son relationship", as Tuska's father was deceased.

The United States enacted the Radio Act of 1912, and all radio transmitters were required to be licensed. Tuska was issued a standard Amateur license in early 1913 with the call sign 1WD. On January 14, 1914, local amateurs founded the Hartford Radio Club, and Tuska became the club's secretary. In the fall of 1915, he began teaching a radio principles class at the local Y.M.C.A. Tuska also began experimenting with radiotelephony, using an arc transmitter of his own design which employed tungsten electrodes to make audio transmissions. In March 1916, he was broadcasting semi-regular phonograph concerts at a time when virtually all radio transmissions were still employing the dots and dashes of Morse code.

Founding of the American Radio Relay League and QST magazine

Under the provisions of the Radio Act of 1912, most amateur stations were restricted to operating on a wavelength of 200 meters (1,500 kHz), which effectively limited their transmitting range to about 25 miles (40 kilometers). In the spring of 1914, Hiram Percy Maxim began promoting the idea of a national organization of amateurs that would transmit messages over greater distances by organizing relays. This resulted in Maxim's incorporation of the American Radio Relay League, with Maxim as president and Tuska the organization's secretary. At this time, Tuska also resigned from the Hartford Radio Club.

Communications proved difficult throughout the new league, so Tuska suggested the establishment of a magazine to promote and coordinate the organization's activities. He founded QST magazine on advice from an uncle, which acted as the official publication of the ARRL. The magazine was personally owned by Tuska initially, and he became its first editor. The publication was prepared at his mother's house, with the first issue dated December 1915.

One of the provisions of the Radio Act of 1912 was that amateurs could be issued "Special Amateur" licenses, in a limited number of cases where it was shown to be of value. These permitted operating in wavelengths from 600 to 200 meters (500 to 1,500 kHz). Maxim successfully convinced government regulators that relay work fell into this category, and Tuska was upgraded to a Special Amateur license in the spring of 1915, with the call sign 1ZT, which permitted operation on the standard relay wavelength of 425 meters (706 kHz).

World War One

In April 1917, the entry of the United States into World War One resulted in all civilian radio stations being shut down for the duration of the conflict. Tuska hoped to continue publishing QST, but it proved impossible with all amateur stations now silenced and large numbers of their operators entering military service. The magazine suspended publication after its September 1917 issue, and Tuska applied for and received a commission as a Lieutenant in the U.S. Army's Signal Corps. He was posted in Washington, D.C. initially, and then established a radio training school at the Ellington Airfield near Houston, Texas. He was later transferred to the radio school at the Firing center at Camp McClellan in Alabama. After the war, he returned to Hartford.

Initial professional work

In late 1919, the government ban was lifted on amateur radio stations, and Tuska was issued a standard amateur license with the call sign 1AY. However, he was the family bread winner; he was listed as "head of household" in the 1920 U.S. census, living with his mother and grandmother Annie E. Ruddell, who were both widowed. Therefore, he became focused on earning a living and turned to the professional side of the radio industry.

At the same time, an effort was being made to revive the dormant ARRL, and an eight-page "midget issue" of QST was published in April 1919, where it was announced that $7,500 in five-percent, two-year bonds were being sold in order to restart the league. Approximately $4,700 of these funds were allocated for purchasing QST from Tuska and paying several months of outstanding printing fees. The fund raising proved successful, and monthly publication of QST resumed in June under the new ownership.

C. D. Tuska Company

In 1920, Tuska established the C. D. Tuska Company in Hartford with Maxim's help, after an unsuccessful attempt to market an electrical experimenter's kit. He later began offering radio equipment, eventually manufacturing radio receivers for amateurs and experimenters. As part of this effort, he obtained a license to use the Armstrong regeneration patent, which was an important advance in radio reception. Tuska's company initially was a minor concern oriented toward the relatively small amateur radio market, but a nationwide increase in the number of broadcasting stations in 1922 caused an explosive growth in the radio industry. Tuska's Armstrong license only covered amateur and experimental offerings, in contrast to the commercial rights held by Westinghouse Electric & Manufacturing Company, but a series of court rulings later clarified that radio receiver sales to the general public was included as part of the amateur and experimental rights.

It was announced in late March 1922 that, as a result of rapidly expanding demand, there were plans to increase the company work staff from 35 to 125 persons. By early June, it became necessary to move into an even larger factory, with the staff now numbering 175. In 1923, Tuska and Robert Miner developed a modification of the original regeneration circuit which was called the "Superdyne".

Eventually, demand outpaced the company's capabilities, so it began farming out some activities to other concerns, including the A. C. Gilbert Company in New Haven. Westinghouse soon sued to eliminate this practice, claiming that it violated the non-transferable provisions of the rights granted by the Armstrong license. In late 1925, it was announced that the C. D. Tuska Company was being acquired by another radio manufacturer. This turned out to be the Atwater Kent company, which required an Armstrong license in order to fend off its own legal entanglements with Westinghouse.

Radio station WQB

In August 1921, the C. D. Tuska Company was issued a license for a Limited Commercial radio station with the call letters WQB, which was located at Tuska's home at 136 Oakland Terrace. The station was used to investigate developing radiotelephones for two-way mobile communication, and an August 1921 report noted the successful test of "a full-fledged wireless outfit in the rear of [Fire Chief John C. Moran's] Marmon touring car".

WQB was also one of the first post-World War One stations to conduct regular entertainment broadcasts, although at the time the station received its initial (and only) license in August 1921 there were no regulations in the United States defining broadcasting, so WQB was never formally classified as being a broadcasting station. By February 1922, it was reported that the station was transmitting on 360 meters (833 kHz), and Tuska had "just completed a 'broadcasting' room" studio. The most ambitious programs were twice-a-week evening broadcasts from the Capitol Theater, featuring organ recitals by Walter Dawley. But Tuska soon suspended most of WQB's broadcasts, with the explanation that he "was obliged to discontinue broadcasting as he needed to devote all his time to the activities of the C. D. Tuska Co." Although there were occasional reports of additional broadcasts as late as April, regular operations had ceased, and WQB was formally deleted on June 24, 1922.

Later life

The remainder of Tuska's working life was in the radio field.

In March 1922, he participated in the establishment of the Hartford Courant's new broadcasting station, WDAK, even loaning the transmitting tubes formerly used at WQB in order to help the newspaper start operations. After the sale of the C. D. Tuska Company to Atwater Kent, he began working in that concern's patent office, earning a law degree from LaSalle Extension University in 1934. The next year he joined the Radio Corporation of America, where he became Director of Patent Operations in 1947. He became an expert in the field, authoring books that included Patent Notes for Engineers in 1956, Inventors and Inventions in 1957 and Accounting and Tax Aspects of Patents and Research (with J. A. McFadden) in 1960, as well as eight Journal of the Franklin Institute articles, including "So, You Want To Be an Inventor".

In 1974, following the death of his wife Edith, Tuska moved from Princeton to Hightstown, New Jersey. At the time of his death in 1985, he was living in Cranbury, New Jersey. His Trinity College obituary reported that during his life he received about twenty patents, and his memberships included the Institute of Electrical and Electronic Engineers, the Philadelphia Patent Law Office, and the Old Guard of Princeton.

In 1982, Tuska was inducted as the second member of the American Radio Relay League's Hall of Fame, and in 2001 he was included, as "Co-founder, ARRL", in the inaugural class of CQ magazine's "Amateur Radio Hall of Fame".
