I have enough ferrite beads in my shack to sink a boat! The problem you
have is primarily radiated RF. The final nail in the coffin here was very
heavy chokes on the main AC sources in the shack. Every wire more that 4'
to 6' long makes a great antenna as close as your radiators are.

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

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
