[Elecraft] USB noise

[Matt Zilmer]

Some of the down-market adapters have poor shield attachments.  Could
it be that in handling your adapter, you caused the shield to loosen
up or detach at one end or the other (of the cable)?

The KUSB doesn't have this problem, btw.

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).
