[Elecraft] USB noise

[Leigh L. Klotz Jr WA5ZNU]

I had some noise from USB activity to my EMU-0202 which occurred even when I
had the sound device unplugged!  I noticed I had a USB / RF mouse and the
USB cable paralleled the 12v power cable to the K3 for about a foot.  Moving
that cable eliminated the noise.
