Hi Guys:
I'm in the final fase of the avionic installation in my RV8; and regarding comm radios I'm using a GTR20 and a GTN650Xi managed by a GMA 245.
My question is about Transmitter Interlock, I see that the GTR20 has the pinout for TX Interlock but GTN650 does not; doing some research in VAF I came across a post mentioning this:
"The uniqueness of this new interlock feature is the radio will now detect another radio transmitting and via software will reduce the GTN comm"

So, based on my setup, will both comm radios will have the ability to detect the other transmitting radio? does the GTR20 have this feature also? If any of you guys have had a similar setup, I would love to hear some comments on how you got it working.

GTN650 Transmit Interlock or Lack Thereof
UPDATE: See post #7, Garmin has created a MOD to bring this feature to the GTN series.... This only applies to dual COM installations..... One thing to understand about the GTN650 is that it does not have a COM interlock feature like the GNS series had. I used that feature back when I had a...
