Hey - is anyone here using this brand of COM unit?
I have some questions about PTT wiring, and what is required to get a clean signal:
Studying the harness wiring diagram, I notice the pilot and co-pilot PPT circuit runs in parallel between the second Mic terminals and plug locations 18 & 19, and the wire shielding (earth). This raised a question for me:
Does the MGL V6 simply require voltage at the PPT terminal locations, to “switch” the PTT on and transmit the modulated signal when the button is depressed? Or does a modulated signal from the second Mic terminal actually flow through the PPT switch and into the MGL unit for subsequent transmission?
I have already wired my PPT switches (integral to the joysticks), and fear I may be forced to “break into” the wiring harness (in which case I would try and make it myself). Else I might need to tear my joysticks down again, to revise the PTT earth wiring, also not ideal. But if it's just a question of voltage to switch, then the signal will hopefully be clean enough with my current configuration.

I also asked the guys at MGL about this, eagerly awaiting a reply...
