Flexradio microphone doesn't work

Some days before the biggest SSB contest of the year... some testing ... some issues...

Problem :

- Microphone doesn't work when DAX label is on. DAX must be on to let N1MM+ send audio to the Flexradio.
- Microphone works when DAX is off.

Solution : Go into the Radio Setup screen, Phone/CW, and activate the "PTT override" buttom.

Problem solved.  Easy and logical but you have to know it.

Furthermore, do not forget to correctly configurate N1MM+ in case the output of the voice signal : 

Config ->  Logger+ audio Setup -> Playback -> "DAX TX" (and not the standard speaker).
