The station went through a number of format changes (and later callsign changes), including beautiful music in the late 60s until 1973, oldies (as "Total Gold 101, WCOP-FM") from 1973 to 1974), country from 1974 to 1976, album oriented rock (as WTTK, "TK101") from 1976 to 1978, beautiful music (as WHUE-FM) from 1979 to 1985, and top 40 (as WKKT, "The Cat") for a few months in 1985). In December 1984, while still a beautiful music station, WHUE-FM sought and received the WCOZ call letters formerly on 94.5; the call sign was only used for two weeks prior to becoming WKKT.
