Apparently correct, Lynn.  I had my garage door serviced two weeks ago and the 
last thing the repairman did was pop open the frosted plastic bulb cover on the 
opener and say "just making sure you don't have LED bulbs in here.  They play 
havoc with the receiver on the openers).  He said most everyone in the garage 
door industry knows of that problem.  First I had heard of it.

Subject: [Elecraft] OT: LED Light Bulbs

Just saw an ad for Genie LED Bulbs.

Apparently some LED light bulbs make enough noise that they desense the garage 
door receiver.

These bulbs are specifically low-RFI.

I have no more information.  For all I know, they fix the garage door RFI by 
moving the noise to 14.300 MHz.
