Bond the computer case and radio with strap. That provides an alternate
path for RF reducing the amount on the USB cable.

I am getting a bit of RFI on occasion into my PC; it manifests itself
mainly by apparently disconnecting the com port from Commander. When
this happens, I can restore functionality by selecting a different com
port, and then re-selecting the original correct com port.
I am grounded to a 10' ground rod about 8 ft. from the station via 2"
copper strap. I did install ferrite beads on the USB cables at the
back of the PC as well as on the power cord, and this has reduced the
frequency of occurrence, but I would like to eliminate it altogether.
Any other ideas and suggestions would be most appreciated!
Thanks & 73 de Dave, W5SV
