Here's another feed that you can listen to if you want to hear how OP25 performs with tdma ph2 and simulcast. Unfortunately it can be a little quite on there unless there is an active incident, but if you peruse the more recent archives you should find something to listen to.

The feed is running on an old Core i5 2410M notebook with 8Gb ram and Ubuntu 14.04 MATE. My version of OP25 is derived from git.osmocom.org/op25 "max" branch with some custom tweaks to p25_frame_assembler_impl and p25p1_fdma to clear up some tdma audio glitches and the annoying process_data_unit timeout errors.

If your goal is getting OP25 working, your best bet is to stick with the distribution that has been tested and has installation instructions, Ubuntu 14.04.I installed an Ubuntu 14.04 VM, copy/pasted these instructions, and had OP25 running quickly. It's pretty easy with the instructions.Tom
