[Elecraft] Improved KIO3A Immunity to EMP

[VE3GNO Daniel]

Yapp, this is the way, use twisted CAT5/6/7 as serial cables, Jim is 100% correct.
The document on audiosystemsgroup is one of my RFI bibles, a "must read" by all hams
Tnx Jim,

It would be hard to beat a K9YC serial cable -- CAT5 cable, with one 
pair per circuit, the return of each pair bonded to the DB9 shell at 
each end -- AND every chassis bonded together with short, fat copper.

see http://audiosystemsgroup.com/HamInterfacing.pdf for details
