In November 1988, WQIM applied to the FCC for a construction permit to change frequencies from 95.3 to 95.1 MHz, change the antenna's height above average terrain to , and change class to C2. The FCC granted this permit on February 16, 1989, with a scheduled expiration date of August 16, 1990. To accompany the change in frequencies, the station's call sign was changed to WXFX on September 12, 1989. After completing and certifying the necessary engineering changes, the FCC granted the station a license to cover those changes on May 15, 1990. A format change also happened, once the upgraded signal signed on. The format was flipped to Classic Rock.
