WOOD-FM is an American radio station in Muskegon, Michigan, broadcasting a news/talk format and is owned by iHeartMedia, Inc.. The station can be received across all of West-Michigan and as far east as Alma, St. Johns, and Northwest Lansing, with reception also possible in Eastern Wisconsin across Lake Michigan, especially in Sheboygan and Ozaukee Counties; a short-spaced allocation and higher power means that the Brookfield-licensed WNRG-FM has a much smaller coverage area than most Milwaukee stations due to the heritage of the 106.9 signal in Muskegon. WSAE 106.9 "Home FM" in Spring Arbor, Michigan tends to overpower the frequency across south-west lower Michigan. Since switching from stereo to monaural broadcasting, 106.9 FM can now be heard over a slightly larger coverage area than previously. WOOD-FM originally began broadcasting as WMUS-FM in 1947 at 100.5 on the FM dial; it was Muskegon's first FM station and came on the air just a few months after its AM sister, WMUS. By 1950, WMUS-FM had gone dark, but the station was revived in November 1962 at its current frequency of 106.9 MHz and a power of 2,850 watts. WMUS-FM's original programming consisted of a simulcast of its AM sister. In 1965, WMUS 1090 changed format from middle of the road music to country as "Top Gun Radio." Rather than continue to simulcast, WMUS-FM separated programming and adopted the new call signWFFM. In a "storecast" arrangement with Hasper's, a local grocery-store chain, WFFM aired instrumental easy listening music in monaural sound, interspersed with promotional announcements about Hasper's. The WMUS-FM call letters returned to 106.9 in 1970 and the station resumed its simulcast of the AM's country format. FM stereo broadcasting was added in 1975. Eventually the AM and FM signals switched roles, with the 50,000-watt stereo FM signal becoming the primary station and AM 1090 becoming the simulcast. The simulcast ended in April 2001 when AM 1090 changed to a news/talk format, eventually taking the calls WKBZ. At Noon on January 5, 2011, WMUS-FM became WOOD-FM. WOOD-FM is now an FM simulcaster for sister station WOOD 1300 in Grand Rapids, Michigan and now broadcasts in mono. At the same time the WMUS calls and format were moved to 107.9 FM. It acts primarily to fill in gaps in the AM station's nighttime signal.
