Hi Wayne,
I do not have a Windows 11 machine configured for WSJT-X operation.? They are all Windows 10.
I used my Rev1 QDX today to see if I could find similar issues to what you are reporting.? I did see the same problem.? To resolve it, I first verified that PuTTY could talk to the QDX.? At first, it did not, as the com port changed in the last Windows update.? If the com port is not configured correctly, WSJT-X does not start the waterfall and appears to have audio issues.? To get everything working again, I had to reload the QDX firmware and restart the PC first and then the QDX.? I verified the settings in WSJT-X, and everything worked.
So the steps I recommend are:
1 - Load the latest firmware (1_10) to the QDX
2 - Power off the QDX
3 - Reboot the PC
4 - Turn on the QDX
5 - Use Device Manager to verify the com port number
6 - Use PuTTY to verify transmitter operation
7 - Exit out of PuTTY and close the PuTTY window
8 - Start WSJT-X
9 - Set any values that may have changed (Comm port)
10 - Verify receive and transmit with WSJT-X
It took me a couple of resets to get the above to work.? Something in the last Windows update messed up the comm and audio settings.
NOTE: The QDX is fussy when connecting to Windows.? The PC must be on and connected when powering on or first connecting the QDX.? It has to do with setting the USB parameters.
