AMBEserver (former dv3000d) is a small program which can be run on a Raspberry Pi and provides access to the NWDR AMBE series of products. It makes the AMBE3000R™ chip available via the network using UDP frames. Details of the chip are beyond the scope of this document, but sufficient to say that it is capable of vocoding audio for D-Star, DMR, and P.25 Phase 2 HR and maybe more.

Note: please use this version -
