Here is something a bit off topic to hopeful break the recent tension: Doug, AD8DP has been working on a project he calls DudeStar. It's open source application for amateur radio operators that allows RX and TX of D-Star, DMR, YSF, NXDN, P25 & M17. Either via a Desktop or Android application over the internet, or you can interface it to an analog rig: http://www.dudetronics.com/index.php/dude-star-radio-project He just recently started adding an IAX client to it. It does support software vocoding for the Digital Voice modes. However the code that is out there to do this for D-Star needs work as it sounds poor. If you know someone with some talent I did write about this in the most recent issue of TAPR's PSR, or you can read here; https://www.qsl.net/kb9mwr/projects/dv/codec/ambe.html Steve, KB9MWR
