THEMA:

I doubt that it is possible. PPM needs a defined high/low signal ... analog audio signals usually are decoupled using a capacitor, which does not support DC signals. I don't think that you would get a reliable PPM signal with sharply defined edges and signal flanks.

I've used one of the available switches to select either the headphone or PPM output signal - the easiest solution and it works perfect!

Can you elaborate this a little bit?

I guess what emax means is rather a software solution that provides a PPM output from the respective controller than switching the signal by hardware. But hardware switching at least is easy to realize without the support of Jeti.

This is how I understod it . For me it sounds like he already have created this solution and I would like to know how and best would be to have some pictures .

Hello, due to the lack of a standard PPM-out/in connector on the outside of the transmitter case and no available software solution yet, I’ve used one of the installed toggle-switches to switch between the standard audio or the optional PPM output signal wired to the headphone jack.

Of course this isn't my favor solution (a software solution only as suggested by Edgar would be perfect), but it's quite simple to implement and works well. If you really need all installed toggle-switches (→ functions) for your models, replace the desired toggle-switch by a double-pole version and you still have all functions available plus the additional choice of either the audio- or the PPM-out signal available on the headphone jack…

I'll upload a picture of my hardware solution as soon as possible.
