I really wish we could get this in the SF market.
There's a conspicuous hole here, in that many other markets, I've noticed, have at least one oldies or oldie-adjacent station (the closest thing to "oldies" SF has (that I know of) is iHeartRadio's 80s+, which technically counts, but I guess I share more in common with the 55+ demo than 25-45, so...).
KYNO and KVIN out of Fresno and Modesto, respectively, are good, but as I believe I've mentioned elsewhere, it seems like one has to be really good at DXing to enjoy them (although at 50kW, KYNO comes in pretty well most nights, and can sound fairly decent with a good radio).
