No static at all, FM. We talked about AM radio yesterday, so today we’ll look at FM radio. FM stands for frequency modulation. You remember in amplitude modulation, or AM, the wave length remains the same while the height of the wave varies. In frequency modulation the height of the wave remains the same but the length of the wave changes as the signal is modulated or broadcast. FM was Invented in 1933 by American engineer Edwin Armstrong. He held 42 patents and received numerous awards, including the first Medal of Honor awarded by the Institute of Radio Engineers, the French Legion of Honor, the 1941 Franklin Medal and the 1942 Edison Medal. He was inducted into the National Inventors Hall of Fame and included in the International Telecommunication Union’s roster of great inventors. FM is far less susceptible to interference and the signal is basically line of sight, so the taller the tower the better. That’s why you’ll find many FM broadcast towers on the tops of mountains. In the United States there are about twelve thousand FM radio stations. WZRV-FM, The River 95.3, first went on the air in 1980. From 1980 until 1983 the call letters were WIXV. From 1983 until 2000 the call letters were WFTR-FM. In 2000 the call letters were changed to WDRV and in 2001 we became WZRV. The River 95.3 is a class A radio station and broadcast with a power of 6000 watts, 24 hours a day.
