This is a truly fantastic radio it competing head to head with the Flex radio. The whole project – hardware and software – is fully open source, led by Steve Haynal (KF7O). Although this radio has been around for years the community support is poor. My hope is this post will help document what I’ve found for my own use and maybe help others.
