WMC (790 kHz) is a commercial AM radio station in Memphis, Tennessee, broadcasting a sports gambling format. It is one of the city's oldest radio stations, and still uses its original three-letter call sign. WMC maintains studios in the Audacy, Inc. complex in Southeast Memphis, and has its transmitter towers (a four-tower array) in Northeast Memphis. The station runs direct satellite feeds of BetQL Network and CBS Sports Radio. In addition to sports talk shows, WMC features longtime Memphis disc jockey George Klein's weekly tribute program to Elvis Presley. Klein and Presley were close friends and confidantes during the latter's lifetime and the former's long stint on WHBQ. The station is owned by Audacy, Inc., which (as Entercom) it purchased from CBS Radio in September 2006. WMC and sister WMC-FM were for many years owned and operated by Scripps Howard Broadcasting, along with its one-time co-owned TV sister WMC-TV Channel 5, before SHB sold the stations in 1993. WMC is one of six radio properties in the Memphis market held by Audacy; the others are WLFP, WMC-FM, WMFS, WMFS-FM and WRVR. WMFS and WMFS-FM, like WMC, are sports stations. All three formerly shared feeds from ESPN Radio (which remains on the WMFS stations), although WMFS and WMFS-FM also have local hosts, while WMC sometimes carries CBS Sports Radio. History WMC was first licensed in January 1923 to the Memphis Commercial Appeal, and the call letters reflected the M and C from its owner's initials. The station was initially authorized to transmit on both the "Class B" high-power "entertainment" wavelength of 400 meters (750 kHz) as well as the "market and weather forecasts" wavelength of 485 meters (619 kHz). The newspaper reported that it received WMC's initial authorization via a telegram from the government, and it began test transmissions on the evening of January 17, 1923, in preparation for the station's formal debut on the evening of January 20, 1923. Among the station's unique features were late night concerts from blues singers. Although Memphis was racially segregated, Bessie Smith performed at WMC on October 5, 1923. The station's signal was wide-ranging, and in the summer of 1924 it reported that it had been heard as far south as off the coast of Chile, in addition to having been one of the stations previously heard during an Arctic expedition led by Donald Baxter MacMillan. In the 1930s, WMC carried the NBC Radio
