Hi Martin,
The IC-7610 group on groups.io is a good place to search for this very
issue. The 7610 does appear to be ultra sensitive to any RF present at
the USB port from some of the posts I've seen.

Hi,
I'm writing this for a friend. He has an Icom IC-7610 connected to a
laptop running Win4Icom. At anything over about40 watts it doesn't
take many FT8 transmit cycles before Win4Icom will report a connection
error,the error log shows port closed and the author's statement in
the alert box that appears is that this is most likely caused by RFI.
Accordingly, we want to deploy suitable ferrite on the USB cables. My
thinking is that 3 to 4 turns around one of the medium or large type
31 snap on's that DX engineering sells, at each end of the USB cable,
would be a good start.
Is my thinking here sound or are there other things we should try first?
Thanks
