I will be most interested in this discussion, as I have a friend with a
tower and possible the same issue?
Thanks and 73's,

Cranked up I hear mixing all over 80 meters (Every 10 KC).....Cranked down its gone.  I already eliminated the antennas.  Mixing gets very intermittent in wind as the tower moves around.
