I can tell you we were getting 56kbps 17 years ago and testing 64kps on 25khz ch. I did bandwidth testing with very watchful eyes from govt IT and police officers who wanted to make sure they were getting what they were paying for as //\oto was telling them it was vaporware and not physically possible. I left several sites with very impressed customers. Especially after we did the drive tests.

Hmm.. interesting find Michael. It's interesting to see they are getting (in theory) 128Kbps out of 50khz. This reminds me of Dstar's 1.2Ghz DD that did the same but out of 150Khz. That's an impressive reduction in utilized spectrum yet these units support 2m, 1.25m, 70cm, and 33cm! I'm curious if these units would be legal for amateur use (do they have an IDer, etc.) and what the solution costs for both mobiles and base stations. Maybe they would consider HAM discounts?
