[RFI] Computer (maybe just USB subsystem) shutting down

[Pete Smith N4ZR]

I have a persistent problem with my computer (and N1MM Logger) shutting 
down every couple of hours when I'm active on the air, requiring a 
computer restart.  I run 1100-1500 watts on HF 160-10, and have common 
mode chokes at the feedpoints of all three antennas.  The antenna switch 
is at the base of my tower, and from there a single run of Buryflex is 
shallowly buried on its way back to the shack, about 150 feet.

I'm wondering if it could be helpful, from an RFI perspective, to put 
another common mode choke on that cable where it enters my house.
