This station began as WTRF AM & FM at a time when many applicants for new AM radio stations were also issued FM licenses (ergo, WTRF's original call-sign meaning, "Two Radio Frequencies"). Thus, both stations went on the air at around the same time, but in FM's halcyon years, no profit would be realized until years later. The FM simulcast its AM sister station for many years, primarily using the FM station as a vehicle for providing local radio service after the AM was mandated to shut down after sunset.
