changing frequency from 60 to 70 also reduces noise.
thanks to all who responded

changing resolution from 1280 to 800x600 dropped noise from S5 to S1.
Switching windows to outlook express upped it to S1.4.

Geeee dont send them to the library. As my wife (the librarian) would say.
He has gotta be kidding! Few libraries even know there is such a thing as
ham radio, let alone have book on it. Unless of course, someone like you or me
has bought an extra, and dontated one to them. She is not gonna go out and
spend 30 or 40 bucks for a book that maybe one guy in the county would look at
(me).
But yes - CRTs have been the bane of communications since they were
invented. Very early on, I operated a BIG )meaning room full of tubes)
computer, which had an input of a tty machine. Hmmmm - the outputs were tty
machines too. Then we finally got a crt, and took days to figure out how to
make it quit intefering with the hundred or so R390 receivers setting next
door. Radio Shack ( usless tho they have become) did have some small split
ring type rf thingies you could wrap the ac and signal cords around to help.
Think they have some square ones now, but the prices, like the few items they
have left in their stores, are crazy. Hey - I needed a 1N270 from them last
week (still do) and they have esentially gone out of the parts business.

Once could write a book on this topic. When you refer to noise, are you
using a CRT or solid state monitor? CRTs can generate a lot of noise and are
typically not well shielded. The easy solution for this problem is to ditch
the CRT and pick up a LCD monitor. As I mentioned in a previous post regarding
this topic, many computers have very poor shielding and generate a lot of RF
trash. Turn off each component until the noise goes away. Much of the leakage
can occur from the cables and sometimes just re-routing the cabling helps.
Also, you might try grounding the computer to your station ground. See the ARRL
Radio Handbook for more information on this topic. Your local library should
have a copy if you do not own this valuable reference.
Regards,
Bernie

Can someone point me to a reference for making a noisy computer quiet?
Especially the video card !
