This station could serve the San Francisco bay area just fine on 5KW.
It's kind of confusing to read the STA, but I believe that's exactly what they're doing. Or maybe 12.5 KW:

The nighttime site hasn't been active for quite a few years AFAIK. I never actually tried to listen to them until they started carrying A's baseball, but up in the foothills I hear them day (fairly strong) and night (quite weak). Something else fades in sometimes at night. Probably CJBC.
