Davis held a staff meeting with his "radio cabinet" and asked them to have a station operational in time to broadcast the presidential and local election returns on November 2, 1920.

Election return broadcasts had been a tradition since shortly after the development of radio, although due to technical limitations initially they could only be done using Morse code, which greatly limited the potential audiences.

However, Westinghouse moved aggressively to establish itself as a national and international provider of radio communication.

Its primary competitor in this effort was the Radio Corporation of America (RCA), which had recently been formed as a subsidiary by Westinghouse's arch rival, the General Electric Company of Schenectady, New York, using the assets of the Marconi Company of America.

Its nighttime signal covers much of eastern North America.

J., and Springfield, Mass., where similar outfits will be employed." An application, signed by H. Davis, was submitted to the Eighth District Radio Inspector, S. Edwards in Detroit, who forwarded it to Washington, and on October 27, 1920, Westinghouse was issued a Limited Commercial station license, serial #174, with the identifying call letters of KDKA.
