[Elecraft] KUSB Noise Query - K3

[Mike Harris]

A few years ago I was receiving noise from my PC on 6M, via the serial 
interface cable.  I was also receiving it when using the KUSB of the 
time with the Prolific chip-set.

I made a new serial cable using CAT-6 and the technique used in the 
"K9YC RFI-Ham.pdf" tutorial, page 38.

This significantly reduce the noise and interestingly when I placed it 
in series with the KUSB it had the same effect.  My new serial cable was 
about 3 metres long and I was going to make up a short version to see if 
it had the same effect.  Unfortunately I never did.
