Unfortunately, D-Star is not compatible or interoperable with P25. The AMBE codec that is used for D-Star (almost always the AMBE-2020) will not decode P25 IMBE encoded transmissions. Sadly, I confirmed this (a) directly with DVSI, (b) by experiments done by a colleague who spent time with one of the "plug-in" D-Star decoders for the specific purpose of attempting P25 interoperability. It might be possible to have a codec plug in board that did both AMBE and IMBE, but the chip that's used in the inexpensive commodity AMBE decoder for D-Star does not do this. I do know that DVSI has a board-level product that will do P25 decoding, the VC-55-PR. Unfortunately, it's just a bit over $900 per board in small quantities.
