ARLA/CLUSTER: HamRadioNow: AMBE Digital Vocoder Exposed

[João Costa > CT1FBF]

In this presentation given to the TAPR digital Communications
Conference Bruce Perens K6BP discusses the AMBE vocoder

Bruce Perens K6BP admits he was wrong about the AMBE vocoder used in
D-STAR and most other VHF/UHF digital voice equipment. It isn't a
black box. The specs are public! But they're so encumbered by patents
that you can't use them... unless...except.... And, what else can you
do?
