Interface noise Icom IC-7610

I have a pulsing noise on the upper bands - 20, 17, 12 and 10 which is loudest on 10 meters. It's a pulsing white noise that I hear only on CQRLOG and only when I have the 7610 selected in TRX control. If I change the polling rate the rate of the pulsing also changes so it must be the signal going through the USB cable from my rig to the computer. This happens only on CQRLOG - not with any other program the 7610 communicates with nor does it happen with any program the rig communicates with on Windows 10. I am using a Tripp Lite USB cable with ferrite chokes and I have additional chokes I put on the cable. My computer is an old Dell Optiplex 380 desk top and I use Mint 20.2.

The noise is not very loud but is annoying - anyone else seeing this happen?

Hi Bill!
I can hear background noise increasing with icom 7300 if there is no antenna connected. It is very small increase, but related to starting cqrlog.
If I connect antenna it can not be heard because of switching power supplies, Wifi networks and electric railroad in neighbourhood.
