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.
KFC (defunct radio station)
Initially there were no formal standards for radio stations making broadcasts for the general public, and a variety of stations, most operating under Experimental or Amateur station licenses, conducted broadcasts on a regular schedule. On December 1, 1921 the U.S. Department of Commerce, which regulated radio at this time, adopted the first regulation 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.
