I have an update.  Several attempts have been made by KXWA to clear up the
interference problem.  Their communications engineer (Paul Pettit, Phantom
Engineering: sharzam at netzero.net)  had a real challenge.  He first tried
some off-the-shelf filters.  These failed.  He then went to a company from
Toronto Canada, Tin Lee Electronics, Ltd.  They built two highly selective
notch filters to suppress the KXWA signal and allow 90.1 FM to pass.  After
installing, there was some improvement, but Paul came to the conclusion that
our FM tuner simply was not selective enough.  He convinced the manager of
the station that he should provide a new tuner.  Today, Paul showed up with
the new tuner (Sony) and it worked.  Our favorite classical channel 90.1 FM
came through crystal clear on our Bose system.  The main TV also cleared up
such that channels 6 and 7 had only very slight irregularities in the
signal.  Remember, we are 60 miles away from the TV transmitter sites.  The
bedroom TV was always on rabbit ears in the past and had some difficulty
with channel 2, but 6 & 7 always came through.  Paul installed a powered
antenna from Radio Shack.  It failed miserably.  I had fabricated a wire
antenna from zip cord that was doing a better job.  Paul has decided to
install a splitter at my yagi TV antenna located above the house and add
another filter for the upstairs TV.  He will also add a pre-amp to both TVs.
I consider his efforts most gratifying.
