D-STAR by definition includes AMBE, any other vocoder is not D-STAR. I
applaud people working to advance the art but D-STAR is defined -- if
what the experimenters create is better, then it will get a following.
(If it doesn't infringe on someone else's intellectual property -- which
means it better get patented or otherwise protected so someone else
doesn't patent it after the fact -- big dollars.)
I think cost is a red herring -- the AMBE chip is around US$20+ per
unit. If the new vocoder can be produced for that price in small
quantities for hams it would be very surprising.
