Apologies if this has already been posted; did a quick search and did not find a reference.
Not surprisingly, Craig was ahead of the game and mentioned this basis of this issue in an earlier post from 2017. (http://sailfar.net/forum/index.php?topic=3652.msg53509#msg53509) Sailfar remains ahead of the curve. :)
In August of 2018, the USCG Issued a Safety Alert (http://saltwatercentral.com/modules.php?name=SaltwaterCentral&op=sw_article&id=4880) referencing potential VHF, DSC and AIS interference from LED lighting.
The interference can impede these radio systems and represents at least the possibility of a safety hazard. The article references a simple test boaters can perform to determine if their installed LED lighting equipment is causing interference.
The test is highly technical: set the VHF squelch with LED's off, turn LED's on and see if the radio detects a signal from the lights.
