Hi All, I have a A200 that I am trying to connect to a Garmin 347 Audio Panel. So far I have the receiving working OK but can't manage to get the transmit to function. I have determined that the problem is with grounding pin 9 on the Icom to allow the PTT to function, where is this connected to on the 347? I had been told pin 31 but that is labeled pilot ICS & is an input where I think it should be a grounded output.
Many thanks
