[Elecraft] Garage door interference

[James Bennett]

Last time I had issues with the garage door having a mind of it’s own when i was on the air, I resolved it by simply placing a few mix 31 ferrites on the control wires. Couple at the door opener box on the ceiling and a couple more by the wired transmitter on the garage wall. That cured it, without having to open the box and so any soldering.
