WJTT (94.3 FM) is a radio station serving the Chattanooga area. The station operates a Urban Contemporary format and is branded as Power 94 FM. They are owned by Brewer Broadcasting and is licensed to Red Bank, Tennessee.


WSIM FM was licensed in the Chattanooga, Tennessee area, and it was physically located in Red Bank, TN. Owned by Roberta Davis, WSIM-FM operated first as a true album-oriented station. Anything was playable, except country, bluegrass, and any songs that would violate FCC regulations. In the mid- to late-1970s, WSIM-FM provided a format that concentrated on new music at the time. It was the first station in Chattanooga to play Jackson Browne's Running on Empty album as well as Elvis Costello's "My Aim Is True".

The station also supported the local music community. On Memorial Day, 1978, WSIM sponsored a concert on Lake Chickamauga, featuring female rock singer-songwriter Marshall Chapman. Expecting approximately 1,000 attendees to show up at the beach by Chickamauga Dam, the station was surprised by as many as 10,000 (estimate according to the Chattanooga Times). When the station planned a July 4 concert featuring the Bill Blue Band and Gene Cotten, the Coast Guard served the station with a warning that they would not be allowed to present the concert. Instead, the station broadcast the concert live from its studios. Other live from the studio events included interviews and music with Charlie Daniels, the Nighthawks, Delbert McClinton, Longdancer, and others.

In early 1978, WFLI-AM purchased the station and its license. Immediately upon taking control, the new ownership began to change the format to album-oriented rock (AOR), a heavily formatted and controlled approach to music. In 1979, the station began simulcasting WFLI's broadcast, effectively ending WSIM's free-form radio reputation.

The licensed facility that was WSIM in the 1970s is now WJTT, which began playing Urban Contemporary hits in September 1980, and has been the preferred choice for Chattanooga's African American music programming ever since.[1] In 2011, the FCC granted WJTT a CP for an upgrade from Class A to Class C3, thus increasing its ERP from 4.7 kW to 19.5 kW and an expanded coverage beyond the Chattanooga area.
