Try looping two or three turns through the snap-on, which will
increase the suppression a good deal.   -73, Guy.

This noise sounds like QRN and it happens only if I open the K3 utility or HRD. It does not seem to affect the S meter. I have snap-on chokes at both ends of the USB cable. The strange thing is I just started noticing this a few months ago, before that it worked without adding noise (I think).
