Hi,

I just learned that the Trig TT21 transponder has just received FAA TSO
approval.

I have ordered units which should arrive in about 2 weeks. You can see
details and order now on my web site he

This is a very exciting new transponder. It is very small and light, yet
powerful and full-featured. It is a Mode S transponder with a built-in
altitude encoder. Since the head is separate from the transponder body, the
transponder body can be mounted closer to the antenna (if desired) - which
is nice. It also supports 1090ES ADS-B out. You can see dimensions on my
web site. It is very small!

Good Soaring,
