Like many things you continually repeat Mike, this simply isn't so!

You can buy many single frequency ADS-B receivers. Mine (made by Dual)
also lacks the PCAS feature that is built in to Powerflarm.

Why did I buy it? Mostly for the free FAA weather.

The Dual XGPS170 ADS-B receiver is a properly designed unit that fully supports the US UAT/1090ES environment. It is a single frequency (UAT) receiver. However it supports TIS-B and ADS-R, so you will see all 1090ES ADS-B OUT and Mode C transponder equipped aircraft, if you are within range of an ADS-B ground station AND you are ADS-B OUT equipped (either 1090ES or UAT). Without being ADS-B OUT equipped, you may see TIS-B traffic if there is an ADS-B OUT equipped aircraft in your vicinity, but I wouldn't count on that..

If you installed ADS-B OUT in your glider, this unit would give you much better collision avoidance information identifying other transponder equipped aircraft than the PCAS function available in PowerFLARM or other PCAS type devices.

Just out of curiousity, what app are you running with this unit?
