WDMJ (1320 AM) is an oldies radio station licensed to Marquette, Michigan, with a power output of 5,000 watts during the day and 135 watts at night, covering much of Marquette County, Michigan. It is the oldest continuously operating radio station serving Marquette County. The station is owned by AMC Partners, LLC, through licensee AMB Partners Escanaba, LLC, doing business as the Radio Results Network and broadcasts from studios on Ridge Street in West Marquette.[1]
WDMJ has been broadcasting for several decades and was originally owned by The Mining Journal, Marquette's daily newspaper (with DMJ standing for Daily Mining Journal). It began broadcasting in 1931 as Marquette's first radio station with the call sign WBEO, changing to WDMJ on November 15, 1939.[2]
On May 11, 2020, a fire broke out at the WDMJ transmitter site.[3] The station requested a Special Temporary Authority (STA) from the Federal Communications Commission to use a temporary long wire antenna and to reduce operations to 100 watts.[4]
WDMJ's programming was simulcast on 1240 WIAN, prior to July 30, 2020, when Sovereign Communications surrendered WIAN's license.[5]
In March 2022, WDMJ along with WJPD and several stations in Iron Mountain were sold to AMC Media Partners.[6] WDMJ's programming has been re-aligned to feature the same lineup of syndicated conservative talk radio as sister stations WCHT and WMIQ.[7]
On July 1, 2024, WDMJ changed their format from conservative talk to oldies.[8]
