The 95.7 FM frequency debuted June 1, 1960 as KQBY-FM, companion to co-owned KQBY 1550, with 10,500 watts from Mount Beacon above Sausalito, California. It was the last commercial FM application available in the San Francisco market. KQBY had been the original Top 40 music station in the Bay Area, garnering a huge market share for owner Dave Siegel. After competition eroded listeners, the station was sold to former child actor Sherwood R. Gordon, who changed the format to "beautiful music".
