See, while I don't like AMBE, that's a bunch of shenanigans. You can
roll your own stuff with D-STAR:

D-STAR *is* an open protocol. D-STAR Audio, however, has a codec that is
encumbered by patents, I'm not touching AMBE, but I enjoy the idea of a
digital data mode developed within the past decade. Don't throw the baby
