Page last updated on: Sunday, March 22, 2015 Ham Radio Digital Voice Comparison In this edition of the Ham Radio Now show Roland Kraatz W9HPX presents his research on D-STAR, DMR and Yaesu Fusion



The Charlotte NC Digital Radio Group is kinda nuts for the DV systems. They don't pick favorites – they put them all up. Their D-STAR system is older and more evolved (multiple sites on 144, 440 and 1200), but they've added DMR/MotoTRBO in a big way, and recently installed one of the Yaesu C4FM "Fusion" repeaters (though they're not "fusing" it - they run it digital only). They've got an NXDN repeater on the bench. Only P-25 [and dPMR] is missing.



In this talk from the Charlotte Hamfest, Roland Kraatz W9HPX presents the research he's done on D-STAR, DMR and Fusion. No on-the-air comparisons (see Episode 161 for that). This is a slide show that compares operational capability and some tech specs.



We're a few weeks away from Yaesu's North America release of WIRES-X, the Internet linking system for Fusion, so Roland only has a few details on that based on manuals.
