WMC-FM (99.7 FM, known as "FM 100") is a hot adult contemporary radio station serving the market of Memphis, Tennessee. The station is notable for being an FM "superpower," with a transmitter that greatly exceeds current Federal Communications Commission restrictions. Of stations in the FCC's Zone II, WMC-FM is the most powerful. The station's license is currently held by Entercom Communications, which purchased it and sister WMC (790 AM) from CBS Radio in 2006. The two radio stations, along with former sister station WMC-TV (channel 5), were originally owned by the E.W. Scripps Company, publisher of The Commercial Appeal, prior to 1993.
Taking beam tilt into account, the station's effective radiated power is rated at 300,000 watts horizontal polarization and 100,000 watts vertical. The station's antenna is 277 meters (909 ft) high and located along Crestview Drive in Northeast Memphis. Current FCC restrictions were passed in 1962 and mandate a 100 kW maximum across most of the country on the FM band (though some of the more densely populated areas are limited to 50 kW). The station is calculated to exceed power restrictions by 4.6 decibels. However, WMC-FM was grandfathered in, since it went on the air before the restrictions. The station's studios are located in Southeast Memphis.
Unlike many other stations, WMC-FM has retained its same general format since the 1970s. In fact, many of the staff members of the radio station have worked there a decade, or even longer. Most notably, Ron "Hey Now" Olson has been the station's morning host since the 1980s, partnered with Steve Conley (now afternoons on WGUE) on the morning show since the early 1990s. Tom Prestigiacomo had been the afternoon host since 1979 (the same year that Conley arrived), but Prestigiacomo left in 2007 for crosstown rival WKIM-FM, and has now left the radio business.
