KMPX-106.9 when they were underground as well as when they were big band.
As long as were pining away nostalgically for long lost stations, I'll put in a vote for KTIM-FM, 100.9
The North Bay Noise which ran an eclectic "underground rock" format from the early 70s (possibly earlier) into the early 80s. A number of the KSAN and KMPX DJs went through K-Tim, including Bobby Dale. For most of that era, it was owned by the Marin Independent-Journal, San Rafael's skimpy but very profitable daily newspaper, which left the station alone to program whatever they wanted.
KTIM survived more or less under the San Francisco radio radar and provided some great radio, depending primarily on local Marin advertisers. Unfortunately, the signal was weak in San Francisco anywhere east of the Richmond district - not sure about the East Bay.
Some idiot in charge finally flipped the station in the mid 80s to become the Bay Area's first "smooth jazz" station (before KKSF), and called it
The Wave, copying 94.7 in LA. The owners of 94.7 (not sure if it was CBS by then, or not) sued them for copyright infringement, and they had to beat a hasty retreat, becoming
"The Tide." Bankruptcy followed not long after.
