We have to gliders at our club with similar radio problems. Neither have the same setup/hardware.

Both can receive fine. When you press the Push To Talk button other radios hear the click, but no voice.

So what can we learn from this?

I don't know if this is more likely a microphone problem, a transmitter problem, could be the PTT button too, etc?

I didn't have a voltmeter to verify that the battery was strong enough, but can do that next time.

what should our next step be?

These radios are still installed the the gliders, and as far as we know they work months ago and we don't know what changed, and unaware of any wiring changes since then. It is possible that some connection degraded.
One of the radios is a Dittel FSG 50.

Go here http://www.segelflug.de/osclass/ and enter 'FSG50'
For 60 Euros plus maybe another 40 for shipping (total of $125), you can have a replacement including the mounting frame in time for the soaring season. How valuable is your time?
