In my limited experience with RFI in the shack computer (I used to crash 
RecAll Pro on 15 meters routinely) good low resistance common grounding 
between the transmitter, the PC case and the shack bulkhead produced a cure 
after extensive ferrite treatment of lines into and out of the computer 
failed to help.  Not coincidentally, this also cured a common mode AC hum 
problem that had plagued my efforts to use my sound card as a contest voice
