I read that the Trigg is ADB-S out compliant. Has anyone attached a

something. It would be great if the Trigg worked well as a ADB-S
broadcast so we would only have to buy a cheap receiver that would
blue-tooth into my oudie the other aircraft locations. Yes it might
be a dream but I can only hope. Please, everyone stay safe and no
more crashing! If we have another fatality in the west anytime soon,
my wife might pull the plug on her support for this hobby. I know its
safe, but multiple deaths in a short period of time does not send the
right message to my significant other. Please fly
safe!!!!!!!!!!!!!!!!!!!!!!!

The Trig certainly works as an ADS-B transmitter, the FAA is flying
them for ADS-B survey work. I have not hands-on used one. Places out
West currently lack ADS-B GBT coverage and so are less interest to
play with right now.

What collision scenario are you most worried about? Glider-on-glider,
glider-on-GA or glider-on-airliner or fast jet? Starting with a
transponder gives you great visibility to ATC near crowded airspace
and to those airliner and fast jet TCAS systems.

The "cheap (ADS-B) receiver" you probably want is a PowerFLARM. ~
$US1,695 list may challenge your idea of "cheap" but it is a lot of
technology for the price. All other current ADS-B receivers are at
best only a few hundred dollars cheaper and don't offer near the
capabilities for glider applications (and you get flarm-flarm protocol
support for "free").

An ADS-B receiver is useless unless you are also transmitting ADS-B out.
If you have both and you are in range of an ADS-B ground station, you
will see all transponder equipped aircraft that are visible on ATC
radar. If you buy an ADS-B IN only receiver, you will not reliably
receive any traffic info from any ground stations.

Reread his read his post carefully. He started with assuming he had a
Trig TT21 with ADS-B out and then was talking about adding an ADS-B
receiver.

Darryl

The post was asking if anyone was actually using the ADS-B Out
functionality in the Trig. Just because you have this unit installed
and are using it as a Mode S transponder does not mean that you have it
hooked up to a compatible GPS source and have actually turned on the
ADS-B out capability. I suspect that there isn't a single Trig equipped
glider in the US that is actually transmitting an ADS-B out signal today.
