Thanks Bill,
I guess that to screen the controller and compressor is easier said
than done. However in my case, I did prove that it was the yacht
wiring that was the radiator by powering the unit from a pair of 12V
batteries placed next to the freezer. With short leads, the problem
completely vanished. RFI is a complex subject, and it is probable
that no two installations are identical. It will be interesting to
see what happens when I get my new SM2000 next year.
Best Wishes and enjoy your new boat.
