[Elecraft] Garage door interference

[K9MA]

All I did when mine had this problem is to wrap each wire entering the 
opener around a ferrite core a few times. That included the power cord, 
the wires to the switches, etc. I think there were 3 cores: one for the 
power cord, one for the switch wires, and one the light light sensor. 
Generally, all the wires which run together can go through a single 
core. No capacitors were necessary. All but the power cord a small 
enough you can get a lot of turns on a small split core.
