According to "Billboard Magazine" (July 28, 1979), Bonneville Communications owned KBRT prior to the sale to Crawford Broadcasting. Bonneville, owned by the Church of Jesus Christ of Latter-day Saints (LDS), has dabbled on and off in the Los Angeles radio market. Bonneville also used to own KSWD, "The Sound" at 100.3 FM. After changing call signs from KBIG, KBRT was a mixture of secular and Christian music, with all programming taped, and all song "intros and outros" recorded by professional announcers; there was no live, "on-air" talent until after changing over to a completely Christian music format.
