Are they ANR's? I missed that in the link.

In my opinion, the hot setup is a small box (cigarette package size) that
clips to the back of your seat, your belt loop, or your shirt pocket and
your CURRENT HEADSET plugs into that box. Two main advantages: One, it
uses your expensive current headset in any format you desire AND if the
"wireless module" goes TU, you take the headset plugs out of the module,
break the wiretie cord, plug them into the aircraft jacks and you are back
in business. While connected to the module, you can coil the headset cable
up and tie it with rubber bands or thread that can be easily broken in the
aforementioned TU mode of operation.

I have just gotten my response from TI as to their recommendations for the
technology (strangely enough, just started last Tuesday before I got wind of
this nonsense) and their recommendation is to go straight ISM and not fool
around with Bluetooth or Zigbee...this from their senior applications
engineer.

We are going to have a wireless unit by Christmas also, but I decline to
state the year {;-)



how big is the "wireless module that connects to your aircraft RCA jacks"
(and where do I put it)

Aircraft do not have RCA jacks with one exception and that is the antenna
connection on a marker receiver in some makes and models. Some older
transceivers used them on the NAV antenna as well, but nobody uses RCA for
audio.




Is the 8-10 hours on a charge for the 3v Lithium battery a real world
number
or is that without anybody talking?
How many flights will I be forced to dig for the RCA cords and plug myself
in because the battery just died?

If we can get 50 hours on a 9 volt battery for a full 4-station intercom, I
fail to see how a simple microwatt transceiver will only get 10 hours on a
Lion battery.




Most of us can carry on a conversation while ATC talks with other
aircraft,
keeping an ear perked for our N number or location. Although I know
nothing
about "cascading frequencies" I wonder if cockpit conversations as well as
music will be totally cut off when ATC speaks.

We did a hell of a lot of testing in-flight before we decided that the ONLY
priority in the audio system should be to shut the music off whenever
ANYTHING else (ATC, intercom, marker, alert, etc.) comes on. You should
have control of everything else.



Looks like Christmas roll out once they find a headset partner. Someone
else to add to my OSH list!

I'd volunteer, but I really don't like their design mechanisms ... it seems
you have to have an Ipod on board, the priority system sucks, the battery
life is nfg, and while Bluetooth is a great buzzword it really doesn't
belong in this sort of a system.

IMnsHO, of course.
