I used to have RFI problems with old CRT screens but I have never seen an RFI problem with LCD screens. I was suspected the screen' PS but it is strange not to have a problem and only when I run a piece of software to have RFI.

Yes I have read a hundred of times Jim's RFI tutorial and this is really good.

But I need to find first where is the problem and I will find the solution with RF chokes to solve it.

The common sense says that Cortland who speaks for a problem in computer's internet access hit the nail! I couldn't see that and this the next thing I will try...

I will inform you when I find it. I hope to do it in my next visit after the Christmas day...

Tnx to all for the answers. Merry Christmas to everyone with peace and health

Kostas,

Do you have a screen shot showing the noise you see?

Hello to all and Merry Christmas

We have a problem in my club's station. When I turn on the computer's screen everything is ok in our Kenwood 950. When I run VE7CC's cluster program I can see 3 s-units noise. I thought that it was because of the white colour but this does not happen if I open painting which has also a white colour as background. Any ideas where is the problem?
