I agree. I had this exact problem on 80 meters when living close to AM
broadcast. Put a balun at the feedpoint, and the problem went away.
I suggest to install a DC to ground balun at the antenna. This will
present a low impedance connection to ground for the broadcast band.
Granted this is 160 meters your talking about. I believe I traced my
issue to the rain gutters around the house.
Good luck with your issue.

I have no filter suggestions but just be aware if the interference is from
rectification at your station, filters will not help.

During the last 160m SSB contest it became obvious that I am in need of a
serious broadcast band filter. Though I currently have one in-line that I
bought a dozen years ago (cannot recall what brand) I appear to be getting
some bleed through from 1420 AM. If only it were good music, or even bad
music. But the 'fire and brimstone' programs and subject matter are more
than I can take. Suggestions? - Mike, K4CVL
