[Elecraft] Rf in the shack distorting audio

[Stuart Rohre]

Bob, you need quarter wave insulated radials in the shack right at the rig 
ground post to eliminate the hot rf problem on each high band.   Connected 
at the ground rod, they do no good, since that is 18 feet ? away from the RF 
source, (Rig).  Also, how close is your antenna to the rig?  Making that 
maximum distance separation helps.
