And, another incident- in
Portland, had a Phone line to Eugene, passed KXL (1190KHz?) radio station-
Had enough leakage, that it got into the baseband of our microwave system!
we wern't using baseband that high, but when FCC inspected our El Paso,
Texas facility, cited us for re-transmitting that signal, on our microwave
system! Take it to the bank-- dumb things happen! Jim NN7K

KXL (5000 watts) is at 750 KHz. KEX (50,000 watts) is at 1190 KHz. If your
system was anywhere near I-205 at Clackamas, then it would not surprise me
that KEX would get into it. Once I was driving by their tower site and
decided to be funny. It was in my 1969 Pontiac wagon. I commented to my
passengers that "I bet I can really get a good signal from KEX right now.."
and punched the button for KEX on my car radio.. which greeted me with total
silence! I just happened to punch that button while in the strongest part of
their pattern, and it took out the RF amp and local oscillator in the radio
(damn, that was a good radio, too...)



Desense doesn't do anything to the local oscillator. It is merely a
nearby (still in the same bandpass as the AVC detector) undesired signal
strong enough to make your AVC turn the gain way down.
