WMUZ (1200 kHz) is a commercial AM radio station licensed to Taylor, Michigan, and serving the Metro Detroit radio market. Owned by Crawford Broadcasting, the station has a Christian talk and teaching format. Religious hosts heard on WMUZ include David Jeremiah, Joyce Meyer, Alistair Begg, Chuck Swindoll and Adrian Rogers. The studios and offices are located near Burt Road and Capitol Avenue in the Weatherby section of Detroit. By day, WMUZ is powered at 50,000 watts, the maximum for commercial American AM stations. During daytime hours, it uses a four-tower array as part of its directional antenna. But 1200 AM is a clear-channel frequency reserved for Class A station WOAI in San Antonio, Texas. So to avoid interference, WMUZ reduces power at night to 15,000 watts, using a ten-tower array. The transmitter is on Middlebelt Road at King Road in Romulus.

In 1960, Bell Broadcasting signed on an FM sister station, 105.9 WCHD, which later changed its call sign to WJZZ, becoming Detroit's most popular jazz station. 105.9 is still co-owned with the AM station as WDMK. WCHB experimented with a disco music format for a time during the late 1970s. However, WCHB saw its ratings sink during the 1980s as FM urban contemporary stations like WJLB (which moved its format from the AM to the FM dial in 1980) and WDRQ grabbed much of its audience. The station eventually returned to its roots of being a
