[Elecraft] OT Hearing HRD Communicate w/K3

[Leigh L. Klotz Jr WA5ZNU]

You've got plenty of answers about proper cables and application of ferrite
noise suppression, but one thing hasn't been mentioned: Are you using the
Elecraft KUSB or one you bought on your own?
I have a few different USB RS232 devices, and there's one I have that's
consistently noisy.

Also, with the noisy one (when I used it) I found that paying attention to
cable dress helps; i.e., route your RS232 and USB cables away from (perhaps
at right angles to) the audio cables.
