While I'm not a huge expert - and until WinMore Winlink adds support for the FT-991 (it certainly has all the capabilities) - here is a way I think should work - I do NOT have my general yet, so, I am only testing into a dummy load. I only wanted to put this out there as this seems to be one of the most common ones I found via google. I simply used the RT systems to create a Winlink profile, and non-winlink profile so its easy for me to change settings back.
How do I use VOX to PTT from the FT-991’s USB Audio codec?
Cause/Symptom:
How do I use VOX to PTT from the FT-991’s Internal sound card? My Digital mode software requires that I use VOX instead of a CAT command to PTT.
Solution:
Set the following menu settings on the FT-991 to enable VOX for Transmissions through the USB Soundcard that is integrated into the FT-991:
Menu 70 DATA IN SELECT=Rear Menu 71 DATA PTT SELECT=DAKY Menu 108 SSB MIC SELECT=Rear Menu 110 SSB PTT SELECT=DAKY Menu 111 SSB PORT SELECT=USB Menu 114 CONTOUR LEVEL=Default Menu 144 VOX SELECT=DATA
