As I see this is to sign up for there list -no details on there products ! Another "email - send junk mail " list.

From the link:
"Appareo has developed an ADS-B out transponder that's ideal for non-glass panel aircraft. Our simplified solution includes a 1090 ES transponder and certified WAAS GPS in the same box. It's truly an "all in one box" solution."

Sounds pretty good to me. I'd prefer a (cheaper) separate gps/ads-b box so that I can keep my old transponder, but this would be OK I guess-- IF the price were kept manageable. Have to wait and see on that, I guess.

I got a card in the mail yesterday, since I'm on their customer list with my Stratus II. It didn't say anything more, other than they expect to have it approved and for sale by this Fall. I've been considering a new KT74 King transponder to comply with ADS-B Out, but we'll have to see what the price point is between it and the Appareo ESG. I did sign up for the email updates.

I hope it provides a certified GPS solution that can be output with NEMA RS232 signals to other devices that use gps positioning - like they 406 ELT. I also hope it has a better (more reliable) altitude encoder than traditional transponders.

Most altitude encoders are separate items feeding their output to the trransponder, rather than being part of the transponder. Some are part of the altimeter, but most these days are separate blind items, mounted behind the panel. When I had my 430W installed, I also had a pitot/static/transponder check done, and the blind altitude encoder was too far off. It turned out to be a pretty inexpensive replacement, as I recall.

Most encoders have an up / down adjustment, usually two of them-- high altitude & low altitude. With one or two of my past airplanes, I cheated a bit and "self-certified" the txp / mode c. I had to adjust the encoder once when it was consistently off a couple hundred feet when checking in with ATC. Required less than a 1/4 turn on the adjustment screw as I recall, they're pretty sensitive.

I've burned through 2 blind encoders in 2 years. They suck and are very inaccurate as you notice. A separate encoder adds weight and decreases reliability. I cite the certified Trig tt21 mode s transponder which now has an integrated transducer directly in the xponder - no need for an external unit. An aging piece of unreliable gear like vacuum systems.

But my point was not the alititude encoder - but the certified WAAS signal from the gps - which can be routed via RS-232 (3 wires) to sources that needs GPS location info like your 406 ELT.

What's wrong with just GPS signal for your 406 ELT from a handheld? It's still very accurate...
