[FedCom] Garage door opener jamming in Texas now blamed on the NSA?

[KD7JYK DM09]

:I disagree. The 380-400MHz trunk systems are a real problem. This has
: been documented.

True, but that doesn't cover five decades across nearly 3 GHz and light, 
which the
stories have.  Has anyone ever seen or owned a Part 15 remote control device
operating in the 380-400 MHz range?

In my many collections of things, I have various garage door openers and
remote controls.  Frequencies range from 150 KHz (Magic Circle systems) to
nearly microwaves (bluetooth and related), depending more on cost and
marketing of the year than anything else.  In the 60's it was HF with a
very, very few in the 250 MHz range, in the 70's UHF, typically 303-318 MHz,
a very few tuneable units down to 290 MHz, but most on 303 and 315 MHz.

Do a google search for 315 MHz and see what comes up, that's still #1.  Most
recently, the ISDM frequency of 418 MHz, but, honestly, the equipment is so
rare, I have none, for any application and have only heard a signal there
two or three times in the past several years.  Most likely to be affected is
433.925, part of the 433.050-434.790MHz ISDM band.  The number of remotes 
made yearly on and around that frequency are in the tens of millions.  Not 
so much garage door openers, but little key fob transmitters, wireless
thermometers, wireless data links, search google images and ebay for items
on 433 MHz, you'll find a very microscopic fraction of a per cent of what's
out there any given instant.

I think I've wandered a bit, but the story stays the same, although the
technologies, frequencies and decades have changed.

Cordless phones is another hobby.  I have them going back to the mid-60's, 
have pictures of the first in 1902, always marvel at 1983-4 models on ebay 
being called "one of the first", yeah, more than eight decades later, try 
looking in an old rat shack catalog...
