My QMX is working perfect with 12V, but I would like to try 9V to reduce power on FT8.
By lowering voltage with a regulated power supply, qmx is going off at <10V (qmx seems not to be completely off, but there is no audio and no display).
By increasing voltage again, QMX is starting again at >10V (without pressing "On/Off knob).
At exactly 10V QMX is alternately going on and off.
The minimal voltage in protection settings is 7V, why isn't it working with 9V?
