[RTTY] PC components suitable for radio room use?

[Jeff Blaine]

The most critical items in my experience seems to be the LCD and the PC power supply.

Some help is to be had on the if the FCC B listing is shown on the power supply.  Sticking to the serious name brands and the higher 
end stuff seems to offer some benefit as well.

But for serious RFI prevention, there is no better solution that to get some type-31 clamp ons and double/triple wrap EVERY cable 
going to/from the pc.  This is not a "free" solution (each clamp on is around $3) - but if you are looking for a "hardened" pc, this 
will get you very far down the road to that end.  Both in keeping RFI out of the PC, and noise out of the shack.

While the ferrites can be expensive when you consider a guy may need 20 of them, the good news is these ferrites are a one-off 
investment.  Any subsequent PC change/upgrade in the future will not cause you to need new ferrites.

newegg.com is a good source of all things computer, but their sales or
even tech people won't have a clue as to which units have high or low
RFI emissions.  You have to do your homework to determine what you want
to buy and then go somewhere like newegg.com to find and buy it.
