Vacation made me late for this thread. Mike Schumann was curious if
any Trig transponders were "interfaced with a GPS navigation source
and being used for ADS-B out", and Darrl thought that there was one in
a glider, in addition to the FAA installation.

I've had my Trig TT21 flying with 1090ES data-out for just over a
year. The GPS source is my Volklogger, and the GPS Integrity Level is
set to Low. The VFR transponder check verified that squitters were
being sent.

I plan to have the Trig's firmware upgraded soon, so it'll be possible
to turn on the 1090ES data-in capability bit. That way, when my
PowerFLARM arrives, I'll be set to look at ADS-B traffic around me -
and also set to receive TIS-B traffic when PowerFLARM updates their
firmware in the summer of 2011.

John, thanks now it rings a bell, it was you I was thinking of for
having 1090ES data-out.

Thanks
