10m QRP FT8 with the QMX+ (Thursday)

14 stations spotted me early today on QRP FT8.  The RX audio seems to be too low from the QMX+ on digital RX. Sometimes it is (just) in the green on WSJT-X but many times it is too low and still in the red. 

Overnight, I wondered if the RX audio on digital was controlled by the volume control (a good idea?), but adjusting this made no difference. It is as if the default audio setting on digital RX on built QMX+ units is too low at least on a Windows 10 PC like mine. I checked that all settings of audio on the PC were at maximum.

I could see no mention of this in the QMX manual and I think, as yet, there is no operating manual for the QMX+.

It is to be expected there would be some teething issues on early builds.
