While I respect Joe and his business, I believe that Joe is mistaken 
about this. He and I are corresponding privately, and I've pointed 
out some components of the RFI problem that others are seeing. I've 
also seen a number of posts on the NCCC list from good engineers who 
have fixed stability problems with Microham products using ferrite 
chokes on interconnect wiring. That fix would not work (or be 
necessary) if he was right.
