[RFI] just what everyone needs!

[Randy Farmer]

Probably some sort of ferrite incorporated in the insulation to help 
suppress EMI. We've been looking at a ferrite-loaded heat shrink tubing 
at work as an EMI fix for a standard cable. The stuff is VERY expensive, 
but it's relatively cheap when you need to meet a military contractual 
requirement that nobody planned for in the design stage.
