All,
Thanks for the replies regarding PC RFI. Dell states that most of their

As for the RFI issues, I have my fingers crossed. Anyone using a Dell in
the shack? Any RFI complaints?

I have 7 Dell's running here in the room. One running as a server
without any problem. Wish I could say the same for my power
company.

Is your display LCD or CRT?
In my experience, CRT displays are sometimes a major source.
