I was about to suggest that..I.e if you connect the radio directly to an isolated battery and the noise is still there than clearly it is airborne transmitted..If it goes away its probably coming thru the power/ground wires

I will give it a try tomorrow. But I cant figure what I have done wrong. Radio is connected right to the battery, all wires out of the molex connector are shielded, jacks to headsets are isolated with plastic washers through the front panel, have a grounded 50x45cm ground plate inside the body with the antenna screwed right in the center of the plate with the coaxial cable shield grounded straight to the ground plate.
Heres a really simple sketch of how I have wired my antenna.

Are the plastic washers the type with a raised bit that goes through the
hole? They generally come with the jack connectors. Otherwise the
ground side of the plug can ground through the side of the hole.

Hi,
Will that cause receiving noise only, and only with the engine off ?
