[Elecraft] FM station QRM

Easily solved with any low-pass filter on the K3's ANT1 port (EF Johnson,
Nye, Drake, Bencher, countless others).  Then use ANT2 for 6m.  The
multipole LP filters typically have a sharp cut-off above 35 MHz and
response is down some 70-80 dB at FM broadcast frequencies.  Bencher specs
their YA-1 filter -80 dB at 52 MHz with 0.2 dB insertion loss.

I went through this very issue with several Ten Tec transceivers.  I used a
Nye filter that way for 10+ years and it completely cured the problem.
