WDEF-FM is a radio station serving the Chattanooga area, broadcasting on 92.3 FM. The station operates an adult contemporary format and is branded as "Sunny 92.3". 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 WXCT 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.


Once a beautiful music outlet during the 1970s, WDEF has done successfully with its "Sunny AC" format since they made the transition in the early 1990s. Luther Masingill was the WDEF morning host from December 31, 1940 until his death in 2014;[1] he was on the air longer than any other host in radio history. He began working at WDEF and moved to WDEF-FM when the AM switched to a sports format. In 2012, Massingill was one of the first inductees into the new Tennessee Radio Hall of Fame. On November 12, 2012, Massingill was one of several radio personalities inducted into the national Radio Hall of Fame at a ceremony at the Chicago Museum of Broadcast Communications.
