I have found the RS chokes less than useful - get some real ones, type 
77 material - I've bought from these guys with success:

If you haven't, put the computer and monitor on a UPS or at least a 
surge protector of the proper rating to isolate it from RFI coming in 
from the power cord.

The suggestion to get the ARRL RFI book is a good one. I solved all of 
my RFI issues with the help of that book.

Best answer, however, is to find a good price on a big beautiful 19" 
LCD - costco.com has several for under $300. I'm very happy with mine 
- I can fit four MMTTY windows and writelog all on the same screen!-)

good luck! - jeff wk6i
