LED lights causing interference
(gCaptain) The Coast Guard said it has received reports from crews, ship owners, inspectors and other mariners regarding poor reception on VHF frequencies used for radiotelephone, digital selective calling (DSC) and automatic identification systems (AIS) when in the vicinity of light emitting diode (LED) lighting on-board ships (e.g., navigation lights, searchlights and floodlights, interior and exterior lights, adornment)
Some info I ran into. Could this be some reason some people are having radio reception problems?
This is from Tech Talk on Cruising Compass #624. This is not the complete article. I'm not sure about copy right laws etc. to post the whole thing.
