My newest QMX+ kit Rev 3 arrived and was assembled exactly one week after ordering!
The diagnostics test page showed output power (0W) and SWR (random values). Everything else was OK.
All sweep tests showed strange results. Yes, the dummy load was in place.
?
So I decided to power off and check all solder joints again.
?
The QMX was on the table without the enclosure and I did not get a good grip on it.
As I pressed the Vol button for power-off the QMX moved on the table and the
long button press was interrupted, giving *two* long presses like keying Morse M.
?
The display flashed abnormally showing some text and dimmed.
All happened so quickly that I did not see exactly what happened.
No smoke, no hot components.
?
Now I can not power-on as the radio does not react to any button press. Nothing happens.
If jumpered for forced firmware update, no flash drive appears on the PC.
?
This could be a firmware problem.?
Is it possible that the second long press of the Vol button started the power-on cycle while still powering off and writing data to the flash memory?
Clearly,?while performing power-off?and saving data into the flash memory,?the firmware should ignore the button press for power-on.
