What you haven’t seen me blog about in a while is D-Star.
I have kind of lost interest.
What got me interested in D-Star was the opens source software projects and node adapters, allowing you to roll your own.
I had always hoped there would be a SIP translation that would take off. Allowing D-Star to inter-operate with ordinary VOIP. A powerful idea for Emergency Communications.
One key component to this would be AMBE transcoding at the repeater using a DV dongle or some sort of public AMBE proxy. This would also allow people to try D-Star using just a computer and microphone or smart phone.
This never really happened. The Trust Server guys kinda put the kibash on that.
I had hope that with IRCDDB that the trust server concept would go away (fully) and the network would become more decentralized from a select few controlling the whole parade.
So I paid attention to Codec2. It was being designed as a drop in replacement for AMBE. (The existing repeater hardware would be able to pass it.)
What I envision(ed) is plugging a micro computer like the Raspberry Pi into the back of the Yeasu in your car. A separate speaker mic hooked to the Pi, which encodes your voice to Codec2, and wraps that in the sound card created GMSK stream that drives the packet/discriminator connection of your existing mobile:
Kristoff ON1ARF, demos the concept:
However at this point, the Codec2 part still isn’t quite a drop in replacement from my understanding. So it’s incompatible with existing repeater infrastructure.
So combine that with the Trust Server regime, and crap repeater hardware, 1980’s retarded data throughput, and D-Star toys attitude by other controlling interests, and I have hit the end of the road with it.
However it has been interesting to learn about and monkey with.
