[RFI] Garage Door RFI

[Jim McCook]

For years I've easily opened my garage door with the car's remote system 
from 400 ft. away.  A few weeks ago I noticed that was no longer 
possible.  Even from my own driveway it was often hard to open it.  I 
had installed a couple of 11w LED bulbs in the main motor unit.  I had 
no concern, since I have 35 Cree LED floods in my house that do not 
create noise beyond a few inches.  This was different.  Those bulbs 
generated noise in the 300Mhz spectrum that interfered with the 
reception from the remote.  Replacing them with 23w CFL lights solved 
the problem. Beware of LED lights in a garage door opener!!!
