Seems like they looked at dPMR and adapted it. It's a bit late on the scene, but if it takes off then I am minded to support it. However it's up against some pretty stiff competition from D-Star and DMR at the very least. A nicely written spec though, I wish the D-Star spec was as well presented.

Hi everyone, this is a new amateur digital radio standard? This standard intends to replace the D-Star standard?
