Hello all,



I have a problem with RF feedback on 20, 40, and 80 meters. If I run my
AL-811H, I get RF feedback on those bands. Nothing on 10 & 15. Everything
is grounded very well, but it is still there. Any ideas?


Hello, Patrick --- Do you have a coaxial choke balun at the antenna end of the feedline?


Particulars:

Kenwood TS 570D

Gap Titan DX Vertical

Ameritron AL-811H

Heil Pro-set Plus head phones & boom mic



Thanks,



Pat
