Description of problem:

WSJT and JTDX both stop receiving sound after about 2-3 hours when running on Win 11 with ICom 7300. This did not happen with my Raspberry Pi running the same rig.

The waterfall shows black about 2-3 hours after starting the program. The time is not reproducible. This happens with both WSJT and JTDX.

If I quit WSJT and restart, the waterfall shows it receiving sound data again. Same for JTDX.

I am using the Icom 7300 drivers and the USB CODEC is set as audio in/out on preferences.


I have a windows 11 PC (Beelink Mini S12 Pro Mini PC). Rig is Icom 7300. Up to date Icom drivers.

    $\begingroup$ I already disabled all power sleep etc. New info: It is related to logging out of Remote Desktop. As long as I am logged into remote desktop, it works. Seems this has been known for a while by Microsoft, not sure if there is a solution now: answers.microsoft.com/en-us/windows/forum/all/… $\endgroup$ Jun 1, 2023 at 2:25
