Here is the latest in the garage door opener saga. Edison Co. came to
my aunt's house and had her turn off the main power breaker. He then
asked her to have the neighbors try their openers. They worked
perfectly! The problem seems to have been related to a surge
protector she used on her computer system, but I don't know if that's
the final answer. Hers does work fine now. I have been trying to
figure out how a surge protector not connected to the opener could
affect her opener as well as the close neighbors. Must have been
putting out one heck of a spurious signal.

There have been problems with military use of the 300 MHz band for new
radio systems, but this would not cause the door to work only half way.

Assuming the neighbors problems are coincidental, check the
counterbalance spring for the door. They wear out or break and the
opener does not have enough power to work on irs own. By the way this is
not a DIY project because of safety concerns with the springs and the
repairs can be about $300.

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.
