Unfortunately, while this setup worked perfectly at home well away from the
airport, we have an Automatic Weather Observation Station (AWOS)
transmitting continuously on 120.60 MHz only 50-60 feet from the place I
need to site the receiver. Even though this is only a 5 Watt transmitter,
it overloads the front end of the receiver. As soon as anyone keys on
123.00 and the automatic squelch is triggered, all you hear is the AWOS
recording.

Bob-

By now you have probably solved your problem. If not, someone else
suggested that you insert attenuation in the Sony's antenna lead. I think
that approach is most likely to produce the results you want.

If you were to replace the Sony's antenna with a dummy load, there may
still be sufficient signal bleeding into the radio to make your system
work. The interfering signal would also bleed into the radio, but at such
a low level that the Sony's tuned circuits ought to be able to handle it.

If even this does not solve the interference, you may find the problem to
be audio rectification inside the 88.1 equipment, perhaps in the
oscillator stage!

Please keep us informed of what it takes to make it work.
