Can someone tell me if I need a cat cable to the computer or is it handled through the US port on the arduino?

Does the digital mode need a sound card or is it handled via USB?

The CAT functions are done through the USB port on the Arduino Nano.? The sound is through the audio and mic out of the uBitx into the computer through a sound card.? I will be trying it with a laptop built in sound card, however have not done so yet.

I use a usb sound card mounted in the case and just run two usb cables to the computer. The normal computer functions with the built in sound card and the radio is assigned to the usb card.

Got a usb sound card that works well from Amazon for 7 dollars.

should add that I put in two 1:1 audio transformers in line for isolation and a used a dpdt switch to move it between digital and voice mode. On a second one I used a stock relay to do the dpdt duties and swiched it with a spst switch. I tend to use components at hand so that was the reason for the switch.

here's the wiki page on what I did.
