What is "wdef-fm"

WDEF-FM is a radio station serving the Chattanooga area, broadcasting on 92.3 FM. The station operates an adult contemporary (AC) format and is branded as "Sunny 92.3 FM". From Thanksgiving to Christmas Day, it broadcasts an all- Christmas music format. The station can be heard throughout southern east Tennessee, northwest Georgia (often down to northwest metro Atlanta, despite co-channel W222AF there), and most of northeast Alabama.

The FM is the sister station of WDEF AM 1370, and was the sister station of WDEF-TV 12. The radio stations were spun off from the CBS affiliate in the 1990s, and are now owned by Bahakel Communications.
