Re: #qmx SSB Firmware beta 1_01_009 release #qmx


 

Hello Don

I loaded .009 on my 20-10 QMX this morning and decided to do a calibration to see if there were and changes.?
I now get and error ¡° Phase Calibration not possible¡±. This is something new. I didn¡¯t see it on earlier releases. This only appears on 20 meters. All other bands calibrate fine.
?
What would cause this and is it a problem that needs to be repaired?

I mentioned this in reply to an earlier thread. See here:

In summary with the current methodology, phase error measurement isn't always possible. I haven't seen this failure on a QMX+ but it has been reported by others too on a QMX. When the calibration can't he done, the phase error is set to zero, to avoid making anything worse. Don't forget the performance is already very good even without the phase pre-distortion. Of course I'll try to find ways to improve the calibration so it works in these cases too. But for now setting it to zero is a good interim solution.?
