For Pi and all others why not a USB relay board? [....] some USB I/O boards for about $5 that give 16 pins, your choice of input or output on each. If these could be adapted then chan_simpleusb could be used and the radio can provide COR and CTCSS.
Yup, while it was cool before, but now that USB I/O is just not required. The little single board PCs are a far better proposition than a retired white-box, in almost every way, unless you don't want to pay $50 for a repeater controller. The quad-core RPI3 and it's kin are the new easy, with so so so much I/O on board, and it's crazy-easy to use it. What else can we put in software on these boards? MPPT controller? Steve
