OK, I've been flying with the GTR200B for over a month now. The intercom is awesome! Calling TWR from 30 miles away with a "radio check" request resulted in the Controller saying "I'd rate it Loud and Clear Plus".
The installation was complicated by deleting a separate intercom wired into the old KY97A com and also removing and replacing a bunch of 50-year-old spaghetti behind the panel. In addition, I had to remove and replace one side of the headliner to replace the ratty RG58 antenna cable with a nice new RG400 cable. I did the installation and my IA signed it off with no objections.
I owe a HUGE debt of thanks to Bob Turner for literally making this possible!!!

Just got a question about compliance:
1.3.4 COM Specifications The GTR 200/200B transmitter meets the requirements of RTCA DO-186B section 2.3 for a class 4 transmitter.
That is from page 1.3 in the Garmin installation manual. The fact that the 200B has a PMA (only for use with an additional Garmin product) is further indication that this thing "meets" all requirements. For a discussion of why "meets" is just as good as "approved." see above, specifically with respect to transponders.
If you really want to use this radio and your IA won't sign, consider it a PED.
Finally, while I am at it, a friend bought a 450 Stearman - the engine is capable of 38 1/2" of manifold pressure at 2300 rpm, and will go straight up! My first hour as his instructor indicated that he needed a new intercom, so we slammed the GTR-200 in there. I already had a harness ready, so it took a day.
At full power, with the intercom set at 95% squelch and 65% volume, we can talk to each other on the way up! Open mic! Garmin has figured out how to separate and attenuate engine and prop noise, and indeed slipstream noise, from voice. Understand, the only way this works is with David Clark 10-13.4 headsets, a foam cover over the mic, an Oregon Aero leather sleeve over that, and duct tape over the leather. But talk about intercom performance!
I have a thousand Stearman hours, but this thing is plain old exciting!

Did you go into the maintenance area? Let me check . . .
Yeah - see p33 - music mute. You have to set it.

Try Steinair. He still has a few. The intercom is rumored to be locked out in the 205.
I bought a spare two weeks ago.
For older folks, smaller radios are not always better. I have a difficult time with Beckers, etc.

Suit yourself. I am only going by what I was told. It could be that the 205 is a superior radio - the receiver in the 200 had inadequate RF squelch.
I was also told that the intercom in the 205x is enabled. I have no idea what the truth is, but since everything I fly has the 200, it really doesn't affect me.

This was from a Super Cub dot org participant:
Bob, that would be a great price on a 200.
Regarding the 205, here is Garmin’s response to this info.
“There are no known issues with the GTR 205x intercom. Is this a GTR 205 or a GTR 205x? The two place intercom is currently only available with the GTR 205x.”
(The 205x is the experimental

I didnt have time to elaberate earlier. I'm with you Bob, I'd prefer the 200. I know that it is a fantastic radio.
The owner of the plane is going with dual 275s, plus other fancy stuff. I tried talking him into buying a hold-out 200, but non were available at the local avionics shop that he is going through for his new panel of stuff. Plus, he likes the fancy coloring of the 205. The local shop has been installing the 205 now for several months, and havent had any problems.
I did tell him about the intercom issue.
So we shall see.

Most just automatically hook up an external intercom, not realizing the quantum leap forward Garmin made in intercom technology. The Avionics shop insisted on doing the Stearman that way. I re-did it, simplifying the harness by an order of magnitude. I forget what the shop put in - Sigtronics? Their best intercom. Not designed for open cockpit.
