[Elecraft] Anyone near an FM station on ~97.1

[john at kk9a.com]

When I lived near Chicago I heard a mixture of two AM broadcast on 80m
using a 160' high rotating dipole. I assumed that something was rectifying
but I never found the solution. I am curious if you are received this
interference while using bandpass filters.

I have had an interference problem on the top part of 15 meters (21380 to
21450) from an FM station 1 mile from my house whose frequency is 97.1Mhz.
It peaks about S6 and is quite noticeable with only coax connected and no
antenna selected.  I have (2) -K3 and it is present on both.  I installed
new synth boards in one but the interference is still there.  It sounds like
a very broad FM signal.  I had the station engineer do a spectrum search and
he found no issues.  I do not find this interference on an Icom radio.



Has anyone else experienced this and if so have you found any solutions?  I
did a check of just the K3 (a  year or so ago) on battery power and no other
connections and it was still present although much weaker.



Thanks,
