In 1961, the station began to be simulcast on 100.9 KTIM-FM.[11] In the mid 1970s, the station switched from a MOR format to an album-oriented rock format.[12][13] The album-oriented rock format continued through the rest of the 1970s[14][12] and into the early 1980s.[15] In 1980, the station was sold to Platt Communications.[1] The station would end its simulcast with KTIM-FM, and in 1982, the station began airing a big band format.[16] In 1983 the station was sold to Arthur Astor.[17]
In 1988, the station's call sign was changed to KCAF,
In 1993, the station was bought by Mount Wilson FM Broadcasters Inc.
