Re: Computer RFI problems-FARMERIK

I haven't yet found a split choke that works - at all.

I did find that switching to flat screen monitors reduced the RF pollution by almost half.

But I can't use a portable on AM or LW in the same room with the PC with even the flat screen on..

My house hold computers are leaking RFI into the house wiring, and it is acting like an antenna for RFI where ever anything uses AC power.
I started looking around, and noticed at New Egg, some of the APC brand of outs/surge protectors sold for computers and home AV block 70 db of RFI. Also, split ferrite chokes can be fit over cables near computer devices. Higher ferrite mixture numbers are better for lower RF frequencies.

Anyone out there RFI proofed there house already, and have any pointers?

For now it looks like I should get RFI rated surge suppressors for each computer station and the server, as well as the TV and cable box. Also I should get a large number of the ferrite chokes for phone lines and all computer cables.
