Hi Frank,

A worthwhile experiment. Suggestions. Use dirtier QRM rigs. Low cost 
(less than FTDX5000) Yaesu rigs have lots of RF IMD on SSB, even when 
not badly adjusted. W4TV has documented the cause(s) of this within the 
radios. Also, set both QRM rigs and intended signal rigs for relatively 
high distortion audio. Also try intended signal rig with no low-cut EQ, 
no HF boost.
