If you want to do some experimenting someday, take Woodside Road past 280 into downtown Woodside, and try finding a station like 92.7 from there. Then continue west on Woodside Road into the hills, up to Skyline Road. (NOTE: Do not try this if twisty roads and mountain driving make you carsick easily!!) Maybe have lunch at Alice's Restaurant (really!). From there, try dialing around. You'll find a surprising number of Sacramento catches coming in crystal-clear. 90.9, 92.5 (maybe, if you're shadowed from 92.3/KSJO), 93.1, 102.5, 104.1, 107.9. Up there, your elevation is about 2500 ft, and you have electrical line-of-sight to Walnut Grove, where some of the Sacto signals transmit from.
In that particular spot, you are shadowed by San Bruno Mountain. So a weak signal from Sutro may not be able to make it through or around the mountain. Not to mention all those transmitters up at the top of the mountain, shooting their own RF at you from barely a few miles away. And that you're nearly walking distance from SFO, which has a few avionics transmitters of its own.
