In the San Francisco area, there are five, all FM:
KZBR, KOIT-FM, KDFC, KFOG, KSAN.

None observed on AM so far, but given that Susquehanna owns the latter
two stations listed above as well as KNBR(AM) and KTCT(AM), I think
it might be merely a matter of time.

Bonneville, the other owner represented above, only owns one San
Francisco AM, KOIT, which simulcasts the FM 100%. One suspects that
Bonneville is unlikely to invest too much into that signal (which is ND
fulltime).

On FM, the IBOC sideband noise that is generated is noticeable on a
receiver of any but the worst quality. The KSAN IBOC signal (licensed
frequency of 107.7 MHz) is blamed by some for blocking South Bay reception
of Monterey Bay-area station KPIG (107.5 MHz).
