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".

[1] Around 1910, while in the ninth grade, Tuska began earning "pocket money" by selling rubber band-powered model aeroplanes on consignment through the Harris Parker Toy Store.

After clarifying that Maxim actually just needed better quality equipment, 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".

[5] 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 it was reported that 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.

[6] Under the provisions of the Radio Act of 1912, most amateur stations were restricted to operating on a wavelength of 200 meters (1500 kHz), which effectively limited their transmitting range to about 25 miles (40 kilometers).

[8] 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.

Despite this, Tuska hoped to continue publishing QST, but with all amateur stations now silenced, and large numbers of their operators entering military service, this proved impossible.

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 5% two-year bonds were being sold in order to restart the league.

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.

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".

In March 1922, he participated in the establishment of the Hartford Courant's new broadcasting station, WDAK,[26] even loaning the transmitting tubes formerly used at WQB in order to help the newspaper start operations.

[13] 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.
