I am using an external mic and the beta version -003 for SSB. Even the slightest tap or shuffle on the desk with my QMX+ causes the VOX to trip. I am confident the external mic is not causing the VOX to trip. Would Hans spur removal still work if I removed the QMX+ internal mic and would that get rid of the unwanted VOX trips? Or do you think Hans could isolate the internal mic from the VOX detection in firmware?
I noticed the same issue, but raising the VOX Threshold to about 35 or higher completely resolved the issue, and it was still plenty sensitive for my voice (though this probably depends on the microphone being used).? I'm pretty sure it was the internal mic triggering the vox - pressing an encoder button would always trigger it.

If you want to remove the internal mic, everything should work fine - Hans didn't need the internal mic signal for the noise removal, he just needed an A/D converter in the same group.
