Once upon a time, ham radio was all about CW and voice transmissions and little else. [KM6LYW Radio] has been tinkering in this space, and whipped up a compact ham radio data rig that you can build for well under $100. Radio-wise, the build starts with the Baofeng UV-5R handheld radio. The capability to transmit on all sorts of digital modes with the aid of the DigiPi software package. We’ve looked at some interesting digital ham projects before, too.
