I do have rigs for all three, and fusion is close to       D-STAR, but I'd say that dmr has a way to go. Mind you, I'm using them all       with a DV4Mini, as we only have D-STAR and fusion repeaters within range here.                      >        > D-Star uses the older AMBE vocoder while DMR and Fusion use AMBE+2.        > Fusion can also use more Bandwidth for the Vocoder compared to D-Star        > and DMR.        >        > So D-Star should sound clearly worse than any other of the mentioned        > techniques.        > It should also be much more affected by the R2D2 effect (bad audio when        > you have high bit error rates).        >        > Than again I only have DMR and FM, so I cannot really compare.        >                                                         .....Bob, VE5XEF                     --- GEcho/32 & IM 2.50        * Origin: DE VE5XEF (1:140/12)    |
