WXSR airs an active rock music format branded as "X 101.5".
Its studios and transmitter are located separately on the north side of Tallahassee.
In December 1966, its sister-station WCNH-FM was launched running separate programming from its sister station WCNH-AM on 101.7 FM, which moved down to 101.5 FM in 1992.
The station brought its own urban contemporary format programming when sister station WWSD-AM flipped to gospel music in the early 1990s.
Throughout its early years, its call letters became WWSD-FM in 1979, WIQI in 1986, WFHT in 1991, and the current WXSR in June 1993.
