Hello, Bob!
07 Jan 16 10:05, from Bob Seaborn -> Holger Granholm:

Really??
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.
