Overall Spec?

So far all I can see is framing information. Where is the PHY described? Are variable coding schemes supported? Interleaving? Is it C4FM or some other modulation scheme?

Oz, N1OZ

This is all we have for now



of course writing such a spec will be an iterative process. I have some questions whose answers should go in the spec.

-what encoding of codec2 will be used ? 1400? 1600? Another one?

-packet switching might be more desirable than a stream. The cpu have ample abilities for buffering, and packets could be used to transfer some data, not just voice.

-did you have a look at the NPR system made by F4HDK? This is a 430 MHz si4463/ethernet modem, similar to my hn70ap. He has started the definition of a TDMA protocol that COULD converge with M17.

Codec2 at 3200bps is the default mode
