Depending where you are at the wharf you should be able to get some of the FM's
from SJ. the Wharf is obvously near the water, so some FM in SJ have a straight shot into the city there. SF and SJ stations don't tend to intefere with each other. The cities are only about 50 mile apart. so no one shares Freqs. AM does well in SF, because all the hills screw up FM signals, multipath. There are some soild FM's in sf though. Big Power signals or High Towers. KIOI, KOIT, KISQ, KKSF
KFOG. These are San Bruno Mt or Sutro Tower signals.
The # one station in SF and in the Bay area for 28 years has been KGO. A 50kw
AM located about 40 miles outside SF. It's also # 1 in SJ.
AM interference does happen in downtown SF (Noise Mostly) Overhead Trolly
Lines for busses and streetcars. There a fair ammount of electric vehicles in the
downtown grid...Financial district, shopping areas etc.
