On April 1, 1996 at midnight, KCBQ-FM swapped frequencies with KIOZ, transferring the latter station's call letters and active rock format from 102.1 FM (IOZ resembles the number 102) to 105.3 FM. Meanwhile, KCBQ's call sign was dropped in favor of a new identity: KXST, for "Sets FM", with an adult album alternative (AAA) format. In October 1996, just one year after purchasing KIOZ, Par Broadcasting sold its four-station San Diego cluster to Jacor Communications for $72 million, part of a complex four-way swap of stations throughout California.
