I get massive static interference over my VHF when I switch on my anchor light. On - static; Off - goes away. I've tried a couple of things like placing ferrite suppression filters at varies places, but no effect. Clue 1: Could be a new problem since I replaced the incandescent with a LED mast light as I don't recall having this problem before (although the boat is new and it could have always been there and I just didn't notice). Clue 2: Only effects the VHF at the nav station, not the remote one in the cockpit. I have a feeling this is a grounding issue, but not sure where to begin. Any suggestions?
