So why is it that the GPS from the Power Flarm unit cannot be used for the GPS engine to run ADS-B out connected to the Trig or similar transponder? Would this not give ADS-B out, without having yet another GPS unit to power?

Before Darryl get too irritated, here's why: ADS-B Out REQUIRES an FAA-approved, WAAS TSO'd GPS engine that provides a lot more information (health, etc) that a plain old consumer grade GPS, which is what the PF has. The TABS initiative MAY lead to "compliant" GPS sources for ADS-B out in gliders, experimental, and UAVs at a lower price point. See other lengthy threads on RAS for all the nauseating details about this.

So: PF right now will display 1090ES ADS-B out aircraft and non-directional Mode C or S transponders. Unless you have ADS-B OUT, adding ADS-B IN will only add UAT ADS-B OUT equipped aircraft if you are within 15 miles of another ADS-B OUT equipped aircraft (and PF will already show them because they have to have a mode C or S transponder anyway - but as non-directional "PCAS" targets).

As for the TRX-1000 mentioned above, it is probably a 1090ES ADS-B receiver designed to be used with European FLARM; as such it doesn't add anything to what a full-up PF already does. I doubt it receives UAT ADS-B (why should it? Europe doesn't use UAT).
