Hi,
The bummer is that even though it is possible to connect a GPS up to the
Trig TT21 or TT22 an send ADS-B data out, the FAA says that is illegal.
They say you must use an approved GPS costing $3000+. I wish we could
convince the FAA that they are reducing safety dramatically by not allowing
any GPS to send data to the TT21/TT22.

I should add, I have an AEE dipole in the nose about 8 inches from my
feet, but despite 200 watts tested radiated power from the Trig 21, it
does not keep my feet warm... 
Ive noticed a marked change in my sex drive with anything past 200 watts..
Seriously, to get back to the OP, I was thinking of a Trig for the ADS-b out
capabilities and the PF for the ADS-B in. This way my set up will not become
obsolete in a few years. Am I correct on this assumption?
