I have not experienced that problem with my VHF and AIS units. I think this problem happens when the LEDs are close to the antennas. Within a few feet. Plus buying the cheap China LEDs most likely do not help.
I have heard of this with garage door openers. Most manufactures recommend not using LEDs. Of course, the LED light would be right next to the opener's antenna.
Look at the date of article. Maybe, the the newer LED do not have this problem.
They do make quality products, the only problem is you don't know when or if you are getting it.
Craftsman still guarantees their hand tools, but the replacement is not the same quality.
Snap-on still sells quality and service. Quality is not expensive, it is priceless.
I am probably one of the old timers on this forum. Back in my day if you broke something, you could fix it.
Sorry for the long winded soap box.
