[RFI] computer shut down

[Stephanie WX3K]

Ok, i looked at your web pics and see the tower arrangement. 

If 30 meters is the only problematic band, chances are you have cabling dress that is resonant on 30 meters and this may be coupling RF into your monitors/computers. 

Are all your rotor control lines RF decoupled ?

Are all coax cables bonded to an entry panel with a nice low impedance RF ground ?

Do you use power strips with AC line brute force filtering ?

I am asking these questions as a means of understanding your situation

Just trying to help :)

I have a couple of other computers in the shack that are not affected. I did install a new 30 meter beam, and the problem seems to have started after that. SWR is fine. This is running 200W.
