Keith S ktsangel69 at yahoo.comI'm not much of a coder but I can assist in taking captures of a p25 phase II system. There is a site near me. I have a gnuradio setup using rtlsdr dongles. Let me know how and what you would like me to capture. There are audio channels and a Motorola trunking control channel on this site. I've done some basic decoding of the control channel with some windows apps already but haven't tried anything with gnuradio yet.
