Thanks for the suggestions..very nice of you all. I have a friend near
Raleigh who is sending me another filter that he no longer uses since he has
moved away from the problem source. I will try it any way as it is less
labor intensive at least for the moment. Otherwise a balun will be in play
as suggested. THANKS! - Mike, K4CVL

Subject: Re: [TowerTalk] Broadcast Band Filter
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.
