At the moment, I am testing my QMX+ transceiver on 15m and 10m QRP FT8. I am still experimenting to see what sequence I have to use to get the QMX+ soundcards to be recognised by the Windows 10 PC. Currently it works fine although I cannot remember the sequence in which I plugged things in!!
Also, the audio levels need increasing on the higher bands. This can be done by putting the PC in terminal mode and adjusting some numbers. I have yet to do this.
Overall, I think the QMX+ is a good rig. It will be even better when I adjust the audio levels on the higher bands.
