Re: Ubitx v6.1 cat control
You don't need anything fancy.
If your computer has a headphone and mic outputs you take the headphone out from the computer and connect it directly to the mic input of uBitX. Then take the headphone output of the uBitX and connect it to the mic input of your computer. Just watch the levels - both volume out on the uBitx and speaker volume on the PC so that you don't over-drive either one. In WSJTX settings you select the microphone input and and headphone output. If you don't have the correct jacks on the PC you can get an inexpensive sound card usb dongle with mic and phone jack -
