D-STAR questions

[A. Maitland Bottoms]

Nice to see the digital radios at Tacos...
but was there a jack for the KEY?

Even after looking around the vendor's web site, there
are a few questions that might be answered here after some
experimentation.

Is anyone around who can read
http://www.jarl.com/d-star/
or
http://www.jarl.com/d-star/shiryou/STD4_3C.pdf
?
JARL doesn't seem to have anything like those at the
English part of the web site.

Is there some setting to allow using other than
AMBE as the codec? (Or will I be sued if I make a
radio that is interoperable with a D-STAR radio?)

Could we get some .WAV files or equivalent recorded
of the voice through the D-STAR link?
