[Elecraft] RFI

[David F. Reed]

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
