WBCT (93.7 FM, "B-93") is a commercial radio station licensed to Grand Rapids, Michigan and owned by iHeartMedia. The studios and offices are located at 77 Monroe Center in Downtown Grand Rapids. The station has had a country music radio format since July 24, 1992. WBCT's transmitter is at the WWMT TV Tower in Yankee Springs Township near Gun Lake. WBCT has the distinction of broadcasting with the highest power of any North American radio station, at 320,000 watts effective radiated power (ERP). The antenna is approximately up the structure. The station's signal can be heard as far east as Howell, Michigan, as far south as Rome City, Indiana, and as far north as Reed City, Michigan, far west as Milwaukee, Wisconsin providing a coverage area of over 20 counties in Michigan. WBCT is a Class B "Superpower Grandfathered" station, meaning its power was granted before the Federal Communications Commission set maximum standards for FM radio stations. The maximum ERP that would be granted today, under FCC rules, using the same antenna height of 238 meters, would be 20,000 watts. Grand Rapids has two other superpower grandfathered stations, 105.7 WSRW-FM at 265,000 watts and 104.1 WVGR at 96,000 watts. WBCT is licensed for HD Radio operation, and carries The Nashville Channel on its HD2 subchannel.

WJEF also owned and operated a Muzak franchise it broadcast on a sub-carrier. In the mid-1960s, the station, then known as WJFM, switched to a MOR/news/talk/sports format, and in 1967 became more music-intensive, adopting the moniker "The Modern Sound," which Fetzer reportedly soon did away with because he felt the station played too much "rock and roll." From that point and through much of the 1970s, apart from an automated country format in 1971–1972, WJFM was primarily a Beautiful music station. Despite its strong signal, the station usually hovered near the bottom of the ratings during this time. Mellow 93/Joy FM/Classic Rock WJFM changed to an automated Top 40 format in 1977, and then adult
