WDFM (98.1 MHz) is an FM radio station located in Defiance, Ohio. The station is owned and operated by iHeartMedia, Inc., which purchased it from Lankenau-Small Media in 1999. It has a broadcast tower in Sherwood, Ohio. WDFM formerly operated an on-channel booster station in Fort Wayne, Indiana, but did not rebuild it after a winter storm toppled the booster station's tower. The main WDFM signal reaches much of Fort Wayne, but the station does not target that region. During certain conditions, the station can be received in the metro Detroit area.
