With D-STAR unless you buy the pre-programmed DSP chips or the DV

The problem is that amateurs cannot live with the fact that someone
implemented a codec that is better than what they can develop themselves.

There would be no problem when amateurs could actually develop a better
codec than AMBE. But they have not shown they can.

Everyone can put up a site with a statement that they want to develop
something and need donations. But this development needs more than
donations.

Sometimes is it better to just admit that someone did a better job than
you could have done yourself, and just pay him for the work.
