WMPX

WMPX is a radio station licensed to Midland, Michigan broadcasting a Soft Adult Contemporary/Oldies format. The station is imaged as "Sunny 97-7," with 97.7 being the frequency of sister station WMRX-FM. Until January 2014, the station featured the America's Best Music format distributed by Westwood One. WMPX is simulcast with WMRX-FM 97.7 24/7 except for some local sports play-by-play. Although there are other radio stations licensed to Midland, WMPX is today the only commercial radio station that primarily serves the Midland area. WMPX began broadcasting in 1948 as WMDN. WMDN was Midland's first radio station, owned by the city's newspaper, the Midland Daily News. That station continued to use that callsign until July 1971.
