During the 1970s and '80s, KBZT was known as "KBest95" but in the 1980s morphed from oldies into soft rock, before being sold to Sandusky
Radio and becoming "Y95" in 1987. At about the time, the station launched the local careers of morning show hosts Jeff Elliot and Jerry St. James (Jeff and Jer). In the early 1990s, Jeff and Jer moved to rival B100, and 94.9 changed its name to "Mix94.9" adding more gold based music, before reverting back to KBest95. Also in the early '90s, the call letters and "KBest" logo moved to Palm Springs, where it was briefly the number one station in that market. The call letters and logo reverted to San Diego after the Palm Springs station changed format to Spanish. During that period Sandusky sold the station to Anaheim Broadcasting, which in turn sold 94.9 to Jefferson-Pilot, making KBest95 a sister station to country-formatted KSON-FM 97.3. In 2001, after struggling with oldies, the station switched to an "All '80s" format, just a day before rival Mix95.7 dropped Hot AC and adopted the same format. However, this format would also be short lived, and in 2002, KBZT dropped the 80s hits for the Alternative Rock based format it has now as FM 94/9. In 2006, Lincoln Financial Media bought this station and all the others that were owned by J-P, including Smooth Jazz station, 98.1 KIFM and Country station, 97.3 KSON.
