ARLA/CLUSTER: Comparação dos sistemas de Voz Digital - D-STAR, DMR e Yaesu Fusion

[João Costa > CT1FBF]

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.
