The station is owned by Bahakel Communications and airs an adult contemporary radio format.

The transmitter is on Hampton Road in Signal Mountain, Tennessee, co-located with the tower for former sister station WDEF-TV Channel 12, along Walden Ridge.

Park installed beautiful music formats on most of his FM stations, and WDEF-FM played instrumental cover versions of popular songs, as well as Broadway and Hollywood show tunes.

But as the 1980s ended, the format was seeing its audience grow older, while most advertisers seek young and middle aged listeners.

In the early 1990s, WDEF-FM made the transition from easy listening music to soft adult contemporary.
