I know better and just forgot about the close RF problem with broadcast
stations. Have a 50 KW AM station at 1020 Khz about 2 miles away, and
another running 10 KW about 1 mile away...surely this is the problem.
However, many suggested to check the UHF connection since this is an
apparent Autek problem.
Thanks to all.
