The Southeast Mississippi Broadcasting Company, which owned WSJC (810 AM) in Magee, received a construction permit on December 15, 1966, for an FM station to serve the same town.[2] By 1968, construction was underway, including on an auxiliary studio for both stations in Mendenhall.[3] The station did not sign on until April 12, 1970; it aired a variety of musical formats and simulcast the AM during the early morning hours.[4]
In 1987, CSB Communications acquired the WSJC stations for $2.2 million.[5] The FM station increased its presence in Jackson by flipping to adult contemporary as WMJW "Majic 107". The format lasted until 1991, when CSB leased the station to Opus Media, which changed the FM to a simulcast of its WKXI and its "soft soul" format; all 16 WMJW employees were laid off.[6]
