C.D. Tuska Company

In 1920, with Hiram Percy Maxim's help, Tuska established the C. D. Tuska Company in Hartford, CT. 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 regenerative circuit patent, which was an important advance in radio reception. Although Tuska's company initially was a minor concern oriented toward the relatively small amateur radio market, in 1922 a nationwide increase in the number of broadcasting stations caused an explosive growth in the radio industry. Moreover, although Tuska's Armstrong license only covered "amateur and experimental" offering (in contrast to the "commercial" rights held by Westinghouse Electric & Manufacturing Company), a series of court rulings later clarified that radio receiver sales to the general public, for picking up broadcasting stations, was included as part of the "amateur and experimental" rights.

As a result of rapidly expanding demand, in late March 1922 it was announced that 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, in conjunction with 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 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.
