WNMT is a talk radio station in Hibbing, Minnesota that broadcasts over the preassigned frequency of 650 AM. Currently WNMT is owned by Midwest Communications. Midwest also owns six radio stations on the Iron Range; KMFG, WMFG, WMFG-FM, WNMT, WTBX, WUSZ. All six stations share the same studio location at 807 W. 37th Street, Hibbing.
WNMT broadcasts a typical AM station pattern during the day which gives it good coverage over most of Northeastern Minnesota. However at nighttime, the station broadcasts a directional pattern from five towers which makes it difficult to receive south of the immediate Iron Range. This is done to protect signals to the south broadcasting on the same frequency; particularly clear-channel station WSM in Nashville, Tennessee.
