Army interferes with garage doors.

(very interesting info snipped)

No, the local PD/Fire system is a statewide 800 band Motorola p25
trunked(which a lot of Federal users are jumping onto as well), with not
enough towers, leading to multiple dead spots, especially in steel-frame
buildings. Said dead spots aggravated by the insistence at running even
routine comms encrypted.

Thank heavens I don't have to deal with that mess. (My office has
vanilla vhf with a very tall repeater- stone age, but works great.)I
mostly spec and buy vanilla vhf, or trunked 380-412. Don't think I ever
bought any MA/COM, though. Wherever possible, I am cutting our sites
over from standalone systems to be tenants on host trunk system, so I
buy what they can support locally. (lots of XTS5000, lately)

That's it, a garage door opener transmitter with a 500-watt linear
amplifier.

My thoughts exactly. I could open my garage door from anywhere in the
state.

I can't help envisioning the situation. Driver presses the "open"
button, the car's engine labors and stalls under the load of powering
the amplifier, and the garage door snaps open so fast that it rams
right through the back of the garage and skims out into the yard like
a Frisbee (tm).

Have you ever looked at the circuitry in a garage door opener
receiver? No pre-amp, not much more than a tuned circuit feeding the
mixer. Some older units were TRF broadband, and used simple tone
modulation.

No, I've never taken one apaprt. I didn't realize that they were so simple,
but then again I don't have a garage door opener, or a garage door for that
matter.

Most of them are so poorly designed you wonder how they work, at all.


I had a friend who owned a garage door business, and ended up
repairing the things for a few years. I even repaired one of the '50s
transmitters that was mounted under the hood of a car. What a piece of
junk!

Must be a slow news day in Maryland-

Every day is a slow news day in Maryland. I miss NYC where the local
news was often as interesting as the national news. Like when I rode
my bicycle by the US mission to the UN and the door was bombed an hour
later, iirc. Maybe it was a day later, but still.

this has been going on for years,

Thanks to everyone.

for some reason, remove NOPSAM

Try the news in Orlando.. Nothing compared to NYC, but there is a shooting
every night! Crime has been on the rise here for the last 4 years or so.
I'd rather have no news and low crime.
