Brief Description: PTT Notes - Pilot PTT ground COMMON with trim on s
Note for future reference: Per Ray Allen G-207 stick grip assembly, wiring diagram 2 was used. Diagram 1 was used when running power through the grips. For the Dynon Autopilot Panel with Auto-Trim capability the power for the motors runs through the AP Panel itself and only needs momentary contact ground switches to ground the wire for the direction of trim servo movement. So in this case while Diagram 2 wiring is generrally for two stick grips and relay decks, I was able to use that diagram as it pertains to only using the switches as momentary ground. I just left out the relay decks as the AP Panel serves that same purpose. So, what is the problem with this arrangement - well, Ray Allen tells you to use a common ground for trims and PTT. I had not considered that the normal PTT arrangement is to ground it at the mic. Spoke with Dynon and they think this fine - and also conferred with my friend and avionics tech, Ralph, who feesl this is a non-issue and he will proceed on course. If needed, I can remove the stick and de-solder the PTT ground from common ground and add in another wire. It requires some notable surgery though and I would rather not dig back into that stick wiring as it was difficult to get it all to fit. One more wire would not be that easy to add. Recommendation is to wire as per the Ray Allen diagram and only change it to the more traditional wiring IF there is some sort of audio noise issue, which is unlikely. It is after wall what Ray Allen calls for. The wires will be correctly terminated to audio ground on the mic to allow for future changes if needed.
