WLDR-FM signed on in 1966 by Rod Maxson, a well-known businessman in Traverse City along with Robert L. Greaige who was the one with the knowledge of the radio business. Maxson was the owner of Grand Traverse Auto, the city's Ford dealership. With the exception of the nine years in which they played country, WLDR carried some sort of adult contemporary format for its first 38 years, and today. The station's call letters stood for "Long Distance Radio", suitable since they broadcast at 100 kW.
