Follow the directions here if you need to. In a pinch I guess the first thing you could do is to install gqrx which would pull in all the necessary RTL stuff you need. I’m kind of working on the assumption that you have Linux installed and have your SDR device working. There are tutorials out there, some good but everybody leaves out the good stuff or the stuff they took for granted. Now that I have it working I find that it is REMARKABLY easy and I’m mad at all the geeks out there who never made a simple tutorial. I’m a geek and I messed with it on and off for a year or more and it whipped me more than once. Bear in mind Phase 2 could be encrypted and nothing you can do will decode it. The only things that do Phase 2 are hardware scanners and hardware radios and OP25 for software radios. Some municipal areas are upgrading to P25 Phase 2 so almost gone are the days that you can track them with a police scanner since P25 is a Trunked Radio system and not just a lone frequency to monitor. OP25 is a program that decodes P25 Phase 1 and Phase 2 digital radio.
