Please forgive the slightly off-topic posting here; I know that a lot
of contest operators happen to use IC-781 radios, and I'm looking for
Can anyone suggest how to align the center frequency of the CW Audio
Peak Filter on the IC-781? One of my radio's
APF circuit is significantly out of alignment. I have pored over the
service manual to no avail; I can't find the adjustment
listed in the manual. Any suggestions would be greatly appreciated.
Thanks and 73,
