[TowerTalk] Broadcast Band Filter

[Jim W7RY]

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.
