FM broadcasting
VHF Radio waves do not travel far beyond the visual horizon, so reception distances for FM stations are usually limited to 30–40 miles (50–65 km) They can also be blocked by hills or buildings.

The newspaper enlisted a local radio expert, Roscoe W. Bell of the Northern Radio Company, to set up a radio transmitter at the newspaper building. Arrangements were also made for the local Navy radio station, located at the L. C. Smith building, to participate by sending fight summaries via radiotelegraph, which had a much greater coverage than the radiotelephone station, although limited to listeners able to read Morse code dots-and-dashes. The reported wavelength to be used for a July 1 radiotelephone test transmission was 340 meters (882 kHz). The next day the newspaper reported that the test went well, so, beginning at 11:00 a.m., the radiotelephone broadcast would be sent on 275 meters (1091 kHz), while the Navy's radiotelegraph reports would go out on 600 meters (500 kHz).
