PCB Project: CAT+Audio interface
I've taken a short break from responsible ham radio activities (like continuing on Forester ) to pursue another hardware project. My motivation is that I have been loving to use my Lab599 Discovery TX-500, but I'm getting slightly annoyed about having to remake my CAT control and audio interface "Rube Goldberg machine" every time I operate digital modes. I have a USB hub, a USB sound card, an audio Y-splitter for headset TRRS to TRS-TRS, a USB CAT cable and an audio to REM/DATA cable. It's not that much, but it's tedious when I have precious time in the field. What I would like to do instead is to have a single interface box that incorporates CAT control and an internal sound card interface. This has been done by other manufacturers: the Elecraft KIO3B, Yaesu SCU-17 and the Icom 7300's USB interface all take the approach of using a USB hub controller along with USB UART and USB sound card chip all hard-wired together on a printed circuit board (PCB).
