One thing I've found with the snap on ferrite beads is to wrap the cable
through the ferrite at least three times. End feds are notorious for
RF in the shack

David, put several ferrite beads on the USB (Both ends) and the
network cable & any other cables feeding the computer. (printer, etc)
May also need a choke in the feedline. Robert KD5YVQ

*Subject:* [BVARC] RFI
Due to some HOA C&R, I am confined to attic and gutter antennas for
the time being.
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
