A: After several conversations with those few folks who are experiencing RF interference with their LED TriAnchor light, we think we have narrowed the cause down to the newer more sensitive VHF radios (and/or positioning of the antenna to the light). The radios that seem to be the most sensitive (and thus the interference) are ICOM 504 or 522 and also the West Marine/Uniden 600 models. Older radios or less sensitive radios don't seem to have any issues with interference, so the issue is very isolated as we can tell, however we are working on a way to eliminate the possibility going forward as newer technology becomes available. Our engineering team has devised a fix for the current TriAnchor light using a very specific ferrite bead (Fair-Rite P/N0 431167281), which can be purchased from a variety of electronic parts stores including Mouser and DigiKey. If you have one of the above radios and are experiencing RF interference, you can purchase one of these directly or call us for one.To Install the Fair-Rite P/N 0431164781 bead, wrap the bead around a section of the wire with 1 loop in it and as close to the end by the light as possible. The wires should pass through it twice (as shown in photo). The Ferrite bead is a clamp on type, so no rewiring is required as long as you have enough play in the wire to make the loop.
Again, this is a very small percentage of folks and currently we've honed it to the very sensitive newer VHF radios. As mentioned in our earlier FAQ, we are designing a more eloquent fix into the new circuitry of our 12-24V TriAnchor light which will be available later this spring. We will also include this ferrite bead in our packaging, though most folks won't need it. We encourage you to test your light prior to installation and if you do need it, you will have it readily available.
