Hello, I tested the internal microphone in the menu microphone test. Nice. Now a question: once the beta firmware results in a release, what will be the way to transmit? All controls seem to have already a function and there seems to be nothing left for the PTT function.

Jindra,

Right now for the beta,

a) You need to use an external mic.? The internal mic is not currently supported.? While the internal mic does have some functionality, it won't work well for QSOs - it is currently being use for noise cancellation for the external mic.

b) An external PTT is currently required with an external mic.

?

I'm not sure the internal mic will be supported in the first non-beta release.? Since there is an easy alternative (external mic), it may be a lower priority to fully support.? But when it is supported, Hans will let us know how to control PTT.? We may need to still plug a PTT button in the paddle jack to use it, and use VOX if we don't want the external PTT button.? He may also decide to change one of the current buttons to work for PTT, but I don't see a good combination without sacrificing something useful for SSB.

Hi Stan,

I now have one of Eric's little mics to use.? It is nice and small.

BTW, do I understand that this new CESSB software can be loaded on my 20m QMX rig, besides on the QMX+?

Yes, the SSB software works on all QMX devices, but not QCX or QDX.

And you got a good microphone.? I just assembled my kit from Erik and the mic element he is providing is much better (higher sensitivity and dynamic range) than any of the other 3 or 4 electret mics I have tried.?? Which results in being able to use a lower mic gain and having lower tx noise.

Apparently this microphone works best:
