Been running Trig TT22 transponder for years. Works great.

The Trig transponder is essentially the Dynon Mode S transponder used by a lot of folks.

Actually, I think it's vice versa!

Default Trig

I use both the Trig transponder and radio in my Highlander, both have performed well over the past 2.5 years. I also use the Dynon modified Trig T22 transponder in my RV10. The transponder works seamlessly with the Skyview system.

I have installed dozens of the TT22 transponder. They work great and the form factor is fantastic. What else you have in your panel will determine what I would recommend. The TT22 has its own encoder, so that saves a lot of hassle and wiring, especially if you don't have a digital encoder already. You will need a certified GPS position source, so if you have a 430/530W, a 480 or a 6/7xx GPS from Garmin or a 440/540 Fromm avidyne, you will just need a serial port wire from that. Hop over Tom FL and I'll install a TT22 in your bird for you.

The TT31 is a little bit more e pensive, doesn't have the encoder built in, but fits in the radio stack in a more normal fashion.

I can't speak to the com radios, but from my experience with Trig products, I wouldn't hesitate.

If you have a GRT HX, HXr, or one of their new mini's, GRT will sell you a remote mounted TT22 that you can control thru the EFIS. For ADSB-out just add one wire from a Garmin GPS (4x0W, 650, 750, etc) or a promised $500 GPS from GRT. The former qualifies for the FAA's $500 rebate. Works great.

I have about 25 hours behind a Skyview system with it's integrated Trig Mode ES transponder with ADS-B in/out and it worked great. And that's from a guy who is vehemently anti-1090ES and pro UAT/Mode C for ADS-B out.

Summary of the below long-winded BS: If you need to stay "round" instrument hole size I would go with Trig TY91. If you can or prefer to install a conventional rectangular stack form factor go with Garmin GTR-200.

Under the assumption that you do in fact want a round comm to go into a 2.25" instrument hole I offer the following:

I was at this past Oshkosh (Airventure 2016) looking for a replacement transceiver for my great "round" Becker AR 4201. I hadn't had any trouble with the existing Becker unit but was set on replacing it with the newer Becker AR 6201 transceiver if for no other reason than to get standby frequency monitoring while maintaining existing wiring and connectors. I have only one comm and sometimes when flying with other aircraft miss out on air-to-air communications when dealing with ATC or monitoring AWOS while on CTAF etc. I got spoiled early on with the SL-40 and cannot imagine a comm without standby monitoring. Thanks IIMorrow engineers for being so innovative back in the early 90's.

As I talked to the various vendors at OSH one thing became clear. There was a bias towards the Trig TY-91 over the Becker due to the size, weight and newer design and ergonomics. Plus it was cheaper at MSRP with the possibility of show discounts. I saw the Trig comm units were favorites in many of the newer airframes like X-Cub and had an option for dual control heads with smaller panel real estate needed than the Becker. One of the very appealing feature of the Trig is it's ability to interface with an external GPS for database sharing via the Garmin SL-40 protocol. That will work nicely with my Aera 660. Very cool indeed. I talked to a Pitts driver who praised the large display and simple ergonomics of the Trig, especially while wearing gloves. One only need look at the MGL V10 comm for horrible ergonomics distracting a pilot in flight to grasp how important simplicity is. I have been there and done that with a V10 in a different aircraft and burned my MGL T-shirt.

I talked to the Big Cheese at the OSH Sarasota Avionics booth and he completely agreed on the Trig unit being a better choice despite the fact he could make more profit selling me the Becker. He said it was strictly my choice. Sarasota does lots of installs and have had great customer response to the Trig TY series comms. He shot me a quote packaging the Trig TY91 with a G5 and dual GMA 28 servos and GMC 307 control head for my RV3 with a special show discount and a bundle volume discount. He was unable to discount the Becker. Sorry to abandon my old reliable friends at Becker... but Sarasota made me an offer I couldn't refuse.

So in a nutnshell I scrapped the idea of buying the pricey yet solid AR-6201 in line with my original feeble attempt to re-use my existing Becker harness and went instead for the Trig TY91 with a mandatory quick rewire job to my PSE intercom.

USA Trig support is provided by Mid Continent Instruments and Avionics in Wichita. Wise move on Trig's part. I called Mid Continent with a question about shield termination they were top notch with friendly and helpful support. The two fellers I talked to were truly interested in helping me and discussing my proposed install while cheerfully volunteering helpful hints. I rate their support an A+.

Many avionics manufacturers use quality Trig components in their systems. The Dynon and GRT efis sytems are prime examples. Freeflight Systems uses a Trig control head with built-in altitude serializer for their RANGR UAT out ADS-B systems and it just so happens I am installing one of those too.

I am currently installing the Trig and said Freeflight RANGR ADS-B system in my Aviat Husky panel as part of a mini makeover (ni, "mission creep"). The two avionics control heads look like they belong together next to each other in the panel. I am happy with the quality of the Trig components. As a plus the tray included with the Trig comm LRU has mounting holes identical to the most common legacy altitude encoders. So if you are removing an existing blind encoder the Trig tray can bolt right in without drilling new holes. Genius and thrifty (Trig are Scotts after all).

The Trig TY91 is also a perfect solution for those airframes with fuel tanks just in front of the instrument panel since the shallow control head fits well in low-depth configurations as the transceiver itself is remotely mounted. Think Pitts, early RV-3, Champ, A Model Avid Flyer and the like.

I will report my performance findings after flying it around and in our Class C a few times.

Default Trig TY91

Thanks for the writeup, Jim. Assuming you wire it up correctly to a good antenna, you feel that the 6 watts put out by the TY91 will be enough? Mainly curious since they also have the TY92 at 16 watts, the SL40 has 8 watts, and the GTR-200 has 10 watts.
