Apart from the codec patches for ETSI codec i cant find any other voice
decoding source code in osmocom-tetra trunk. Neither seems to have
entered you in the AUTHORS file.

FAQ on the site says:

"Can your software actually play the voice signal?

 Currently we have no support for that. However, a yet unreleased proof-of-concept version exists."

Why this secrecy for publishing source to decode unencrypted networks?.
Have osmocom been threatened by the tetra manufacturers? 
Would damage sysmocom commercial interests
