Well, I bit the bullet and installed the 003 FW.
Update of FW went all fine, no issue there.
I wired up a electret mic I found in my junk box.
Tested the mic on pc and sounded fine.
I made an adapter using the electret mic and a foot switch for ptt.
The Mic and ppt switch works. But...
Testing SSB TX with QMX on dummy load and listening on my ICOM 7300, the audio is badly distorted before calibration and even worse post calibration. So much so that the speech is unintelligible.
The audio sounds like the QMX is only picking up the peak signals from my voice.
Most of the calibration plots look nothing like the example ones from the release notes. And only a few mildly resemble the examples.
Adjusting mic gain to about 70 seems to improve the audio. However, every time I key up,? there is now an awful lot of noise before I even start speaking. Once I start speaking the audio is ok'ish with a load of background noise.
I tried messing about with other SSB settings with no improvements.
I did find a second electret mic that gave me similar results.
I have now set it back to factory default and seeking advice.
Any suggestions?
