[TowerTalk] Computer RFI

[k8jdc at sbcglobal.net]

Jim,

     My wife received a new computer recently from her employer to use at 
home and it generated HUGE amounts of noise.  I couldn't even pick up 50 KW 
WLW-AM in the same part of the house.  Like yours, the noise was present 
even when the computer was turned off, but I could kill the noise by 
unplugging it.  (I should have forced her to send this no-name computer back 
to her employer to get fixed, but didn't).

     I was able to fix her computer by replacing the AC socket on the back 
of the computer with a Corcom EMI filter-type socket.  I think it was only a 
few bucks and it took care of the problem in my case.  It did require a 
little work with the soldering iron, but still was only about a 10-minute 
job.

73,
