Hans,
?
Here's a case of a QMX+ with current firmware having D109 fail:
?
I doubt it was the speaker and key connector board shorting to the case,
don't see how that would bring down D109.
So probably a matter of him jiggling the power connector.
?
It may be a rare occurrence.
Perhaps most of the other reports of D109 failing were with older firmware.
But many users will hesitate before moving a rig that is powered on.
?
With that I'll give it a rest.
