From 1965 through the early 1980s, the WLBJ call letters were also assigned to sister station WLBJ-FM, operating at 96.7 megahertz[7] under the brands "Natural 97" (Album-Oriented Rock) under the program direction lead of Jay Preston, Greg Pogue, and later Dean Warfield, and later an automated "BJ 97" (adult contemporary).

In 1986, WLBJ was forced off the air by a brush fire that destroyed broadcast equipment at its transmitter site, but the studio building was not harmed.

In return, 30-second spots advertising WBKO's evening news stories were aired over the radio station.
