So, to see a UAT equipped aircraft with a 1090 receiver you need to be close to an aircraft with 1090 in/out. Most reliable way to do this is to put adsb 1090 in/out on your glider.

To be seen by that UAT equipped aircraft, same answer.

With adsb out on the glider and the flarm core 1090 rx, the only issue I'm seeing is latency in the ground relay system.

It will be really neat if a flarm core s/w upgrade adds UAT rx, or turns on all of the h/w in the box, especially the second flarm transmitter. Lacking that, instead of switching to a new flarm box, would it be better to put the money into adsb out?

That said, if I was adding flarm, the new one looks nice.

If you have an experimental glider and a Trig transponder, it only costs
around $400 to add a TN-72 GPS and antenna. That gives you dual ADS-B
Out. With the addition of a Stratux receiver $150-250 depending upon
whether you assemble it yourself or buy a preassembled and tested unit,
you get dual ADS-B In. I have that in my gyroplane. I use a TN-70 in
the Stemme since it has Standard certification.

Flarm receives the ADS-B signals and my ClearNav II and Flarmview
display targets. In the gyro I use an iPad with FlyQ. Works great in both!

One minor clarification. Adding a Trig transponder with a GPS source to your glider gives you 1090ES ADS-B OUT, not a dual frequency ADS-B OUT. It is a great solution that makes you visible to ATC, airliner TCAS systems, and virtually all ADS-B IN equipped aircraft. It will also trigger the ADS-B ground stations to transmit ADS-R and TIS-B traffic, which should be visible via FLARM once Ramy's Beta software gets released.
