Hi,

Are you going to make support for Yaesu Fusion? It look's that voice codec is the same so maybe to will be not so big problem.

Best regards

Piotr

One can probably use the P25 (C4FM) and DSTAR decoders as base references.

Hello,

this is working: http://hb9uf.github.io/gr-ysf/ However it uses many discrete blocks tied together in a GRC (GNUradio Companion) network with other GNUradio blocks so it results in a processing bloat. It takes ~80% of my total CPU on a core i7 5700HQ.

But maybe it is a starting point...

Best regards, Edouard.
