[Elecraft] [K3] SSB TX modulation heard in phones

[Don Wilhelm]

Richard,

FR feedback will not necessarily create a distorted sound, so do not 
rule that out.
One of the best checks to see if it is an RFI problem is to operate into 
a dummy load.  If the problem goes away, it is time for better common 
mode chokes on the antenna feedlines.
