[Elecraft] Elecraft] RFI on K3s

[Jim Brown]

I'm a big fan of Belden cables, but why go to the trouble of a group 
purchase when it is so easy to make your own twisted pair from lengths 
of stranded cable we can buy at the local big box store? The Belden 
cables referenced are primarily used for loudspeaker wiring in big sound 
systems. I specified a lot of it when I was designing systems like that.

Another point though. Hams in general, and Elecraft in particular, 
should be using twisted pair for loudspeaker and power wiring in our 
stations. It's not a cure for RFI, but it is a positive step, because it 
prevents differential mode coupling of RF to that wiring. Ditto for 
loudspeaker wiring in home entertainment systems. Over the years, I've 
cured lots of RFI to these systems by replacing zip cord, glorified or 
plain, with twisted pair.
