Hi Justin,
How do you run CAT control and digital modes just using the Raduino? If this had been documented as an option in one of the places I had been reading I probably would have gone down this route.
The Funtronics digital interface board (thread title) is not a keyer.?
The digital interface board should provide audio I/O over USB, as well as CAT control.?
This is something I have been into the idea of since I have been struggling with using the computer's sound card, since all of my machines have a single combined mic/phones 3.5mm jack, and Win10 is not happy with enabling both at the same time.
