Hi Stan.


You are absolutely correct. Setting mode to NONE in both programs seems to have cured the problem. Many thanks.

Yes, this is caused by new CAT functionality.
Now QMX+ has USB and LSB selections in the CAT; before, if you would try these commands nothing would happen.

So what is happening is that JS8call is configured to set the radio to USB mode before transmit - which before did nothing, now it does.
Check on your radio configuration tab for rig options.? Set the 'mode' control to 'none', and it won't try to change the radio mode, and everything will work.? You can try setting it to 'Data/Pkt', and that may work also by having it set the radio to digi mode: but I haven't tried that yet, and the software may map the 'Data/Pkt' mode to USB, which it does for some radio types that don't support a separate digital mode.
?
And the corresponding thing is likely happening in JTDX, but I don't use that program, so can't help with specifics.

Haaaa

I did exactly the same last night, even though I had read this post... I had my QMX+ driven by WSJT-X and was operating 160m WSPR. I started it and left it running. About 4-5 hours later I came back to the lab to check up on things and noticed it's on USB! Still had lots of 160m spots though! So at least we know USB mode works nicely for WSPR too. Still, Digi mode is definitely recommended for FSK modes as it will give the best performance. So after noticing that I set the WSJT-X mode to "None". Now I need to remember to add some more bold red font warning in the documentation...
