I am installing a 403mc in my plane. I also have a IC-A200.
What is interesting to me is that the flightcom manual shows the PTT switch going to ground, but not to the mic return(changed to "Sleeve") like I have seen in most other mic diagrams.
I could connect the mic PTT to ground to pin #8 on the IC-A200 which seems OK on the bench, but grounding the PTT to the (changed to sleeve - mic return) seems to work as well too.
I would like to hear from folks who have wired up a 403mc with a IC-A200 and learn which PTT/Ground you used and has it worked well.
Thanks!
