PWA and other device

[H2O]

I decided to buy a Mod S transponder with ES, any advice ? Fair Price and easy to connect to paw to get adsb out.
I have garmin GTX 327 so it must be of the same size

Both the Trig TT31 and its King clone (same guts, difference faceplate) are similar in size to the Garmin 327, but you'd need to check the exact dimensions. Much cheaper than the Garmin equivalents.

I Also highly recommend Trig, they have the best backup service you will ever find in aviation

Trig is ES right? Just seen the dimensions it's almost the same of garmin GTX 327

Well, I wouldn't have mentioned it if it wasn't. 

I have had one for over seven years, and have been transmitting ADS-B (from a certified source) with it for the last six.

Thanks Graham I will buy the Trig, but connect with Paw or a Garmin Aera 500 to give gps to transponder in other threads I've seen people connecting paw to trig to feed GPS.not sure wich is best or easier to connect

[Paul_Sengupta]

I'd suggest looking at local regulations about connecting an uncertified GPS to a transponder for ADS-B before committing.

Can anyone give me the link ( if there is ) regarding connecting PAW to Trig 31? I can only found this one of trig 21 and don't know if it's different , although if there's a guideline would be useful.
