Ft891 and digirig

[Constrainted]

OK! I understand you are using WSJT-X and trying to use CAT control to pull PTT. There is also a choice to use the serial port COM device to control PTT.

If you want to use CAT control Denis K0TX has an explanation here:

As for the audio: try troubleshooting method involving plugging the headphones in Digirig’s audio socket to check if there is output from the interface.
