    I picked this up on the Cruisers Forum and looked it up. Apparently some LED lights interfere with VHF, AIS and other on board electronics.

    "The U.S. Coast Guard 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)."

    see the safety alert at https://www.dco.uscg.mil/Portals/9/DCO Documents/5p/CG-5PC/INV/Alerts/1318.pdf?ver=2018-08-16-091109-630

    The radios get great reception. The receive the interference generated by all those LED just fine! har har har

    IOW Don't mount your VHF antenna right next to high-power lighting (that is mostly cheap chinese made LEDs these days).
