If you were to make *technical* arguments more compelling than "neaner
neaner" I might believe that RadioRA is far superior to the RF systems that
have been knocked out by military transmissions.  "It works for me" really
only tells us about your location, your installation and your operational
parameters.

The question here is very simple: "Does RadioRA provide protection from the
kind of interference that has been shutting down RF car and garage
controllers across the country?"  So far the answer to that is "nobody seems
to know for sure."

Ridiculous extreme?  Military transmitters have been interfering with home
and car RF controllers across the country.  The problem's quite real for
hundreds, if not thousands, of people.  Because this is a discussion group,
and the claim has been made that RadioRA isn't prone to the shutdowns that
have plagued people in Colorado and Virginia (you *are* making that claim,
aren't you?) it really requires some further investigation.  I've provided
Lutron's tech support numbers so that anyone considering Lutron's RadioRA
can ask for themselves, at the source, whether RA is resistant to the
problems facing other home control RF users.  That's not extreme.  It's just
being thorough.

Since you don't live in an area known to be affected, your implication that
RA is resistant to jamming really isn't substantiated simply by your
experience.  Want to convince me?  Find an RA user near Elgin AFB or
Quantico that's unaffected.  Or post some sort of technical explanation as
to why RA is immune to jamming that shuts down other RF controllers and I
surely will "give it a rest."  Right now, my admittedly limited
understanding of radio transmissions tells me that a stronger transmitter
will completely drown out a weaker one on the same frequency.

I can think of one way of making a transmitter/receiver somewhat "jam
proof" - it's a modification of earlier military technology - and that's to
use two completely separate transceivers on very different bands in the same
unit.  If one of the bands is jammed, the radio falls back to a far
different frequency.  I've seen nothing in the RA literature to lead me to
believe they've got such a system, but it's possible.  Details like that
would tend to shut down debate and "give it a rest" a lot faster than
yelling FUD in a crowded radio spectrum that's only getting more crowded.

Will RA fall victim to the same sort of environmental changes in its
transmission medium that hobbled X-10 in theirs? Only time will tell what
happens in this increasingly wireless world.
