My aunt, who lives in So. Calif., along with two close neighbors, is
suddenly having problems with garage door openers. Won't open. Stop
part way down, etc. I haven't heard of amateur radio having an effect
on modern garage door remote receivers. How about BPL? Don't know if
it can effect things in the 900 Mhz region, but thought I would ask if
anyone else has seen this.


I'd be surprised at BPL causing this, given its low signal strength,
but I suppose something to consider. I recall hearing of some new
military "secure" communications system having such effect on garage
doors.... but occurs over many square miles, not just one small local.
The problem I read about was back in the South East, I think.

I guess if just a couple houses next to each other are having issues,
one would begin to look in that vicinity.
