[1] On December 1, 1921, the U.S. Department of Commerce, which regulated radio at this time, adopted the first regulations formally establishing a broadcasting station category, which set aside the wavelength of 360 meters (833 kHz) for entertainment broadcasts, and 485 meters (619 kHz) for market and weather reports.
On June 7, 1922, the Miami Daily Metropolis reported that test broadcasts had begun the previous night of its new "radiophone transmitting station".
The transmitter was located on the ground floor of the newspaper building, with installation overseen by Kenneth Richardson of the Boward Electrical Company.
[8] On January 27, 1923, the Metropolis reported that a 100 watt transmitter to be used by the newspaper's broadcast service, that was designed and built by F. W. Borton of the Electrical Equipment Company and installed at Electrical Equipment's offices at Northwest Fourth Street, would make its debut broadcast the next evening.
"[10] However, WQAM was licensed to the Electrical Equipment Company, and WFAW to the Miami Daily Metropolis, and government regulators at the time considered them to be separate stations, so the two are reported individually in a March 1, 1923, government listing of active licenses.
