As I simplify the wiring on our 97 MkII I'm finding items that I wonder if they're necessary, or functional. Does anyone experience alternator noise on their VHF radio when motoring? There is a noise suppression filter on the VHF which is double fused?? These filters (Radio Shack #270-051B) are intended for car stereo use, but our stereo works without noise and isn't equipped with a noise filter.
Found a few of these on my boat when removing old wiring. I have not seen any of the recent manuals I have reviewed require one for the VHF.
