reading this I am not near my shack so I can not look up the HAMLIB version but I did update WSJT-X and then went back to the previous Hamlib Version. and I used a different USB port. That changed the com port. Strangely the QMX in and output changed from QMX...2 to QMX...3. Once I had discovered that the QMX+ worked with the rig set to TS 480. Sometimes it is a little game what to start first but it works in the end. So I will not touch it and not venture into the improved version. Digital will not be my main focus so if it works, I am fine with the basics.? Now I will wait for the feedback from all the SSB testers before installing that.
