[Elecraft] RFI in audio chain

[Jan Ditzian]

I will continue to try solutions, but they seem to be getting random.

I found my long 50-ohm coax run to the 80-meter vertical.  It ends in a 
DX Engineering 1:1 balun with terminals.  I have tried this before.  I 
connected one of the terminals to the vertical and the other to the 
ground base.  The result was an SWR a little lower than with the 
hardline, patched-together feedline, but RFI when I run power.   I do 
not have a choke or balun on the proximal (shack) end.

It is difficult to assess the radials, but I hope to get some more time 
tomorrow to do this.
