I think the mode was designed to offer-up something more useful for
legacy radios. Radios that we already have on the shelf, or in the
garage, collecting dust.
I don't think it really deserves designing a new radio over.
The other mode 2400A is more interesting, and offers a challenge to
those
I would rather add bluetooth support for it. You could then couple it to a
smartphone and have all apps. You could even use a headset.

Lack of interest is a BIG problem. I have my own project which I
mentioned here before. It's basically a PoC, a toy, without much use

Hello,
Yes we need to get more people interested in open DV systems.
My part of the job at the moment is building an UHF modem that also talks
ethernet, so we can connect it to hamnet.
It will be a kind of accesspoint for mobile units, OR, a gateway to build long
range hamnet UHF links.

That's a very well architected project, and I'm not saying it lightly.
Unfortunately the user docs are quite sparse, and it does not have
enough visibility.
Basically I would have liked to know if I could use that to
There was a project based on a CML Micro chip (the same one used in
Tetra handsets), I think Bruce Perens was its godfather. It sounded
very interesting considering those chips were not very expensive, but
I have no idea what the status of that is currently.
My main concern is coming up with a

Hi Jeroen,
This is a very interesting project. If there's anything I would
change, I would add a more powerful CPU, capable of running some other
applications, like chat, maps, email, pictures.
Otherwise you could end up for example receiving a position report but
