So my question is, how long has the G3RUH modem and other CODECs been around that could make a VHF/UHF communications system like D-STAR. From my knowledge, the solution has been available for probably 5+, if not 10+ years. But yet the glorious "Amateur Radio Experimentation" hasn't come up with a solution that used it. Only now, after Japan got way ahead of the rest of the world, has there even been a slight push in Amateur digital technologies. Sure, I would love for there to be a LOT MORE EXPERIMENTATION. But guys, don't try to just do the same thing as D-STAR, go beyond, well beyond what D-STAR can do. Put the JARL D-STAR specs to shame and let's show the world what's possible, not just another "we can too" solution.
What we need is something like the ability to place hot spots all over the place and the hot spots interoperate and are connected to the Internet (as well as other possibilities) and are smart enough to handle handoffs from other hotspots as you move around. And then the radios are probably similar to today's D-STAR radios, but able to handle the handoffs and can provide 4.8, even 9.6 bps error protected data transfer. Forget about duplexers and use 440 in and 1.2GHz out. Doing D-STAR better than D-STAR, well, sounds more spiteful than innovative! Let's be innovative!

This hobby is about experimentation and trying new things, maybe improving on existing commercial implementations, maybe going down dead ends, but so what? If Codec2 comes to fruition then I for one will probably support it in my D-Star repeater software, it'd be fun. Maybe no one will use it, but so what? It's a hobby. I would also like to see a move away from 4800 Bd GMSK and maybe go to 9600 Bd and using the G3RUH modem, most of our radios would be able to handle it, it'd be easy to distinguish on air, and there'd be extra bits available to add some FEC to the slow data.
