OP25 Raspberry Pi Streaming Part 2

22 Replies

So I finally figured out OP25 and I have this brand new Raspberry Pi 3 B + laying around doing nothing.  In this segment we’ll install OP25 on Raspberry Pi and then take our police scanner feed and send it to the internet on Broadcastify.

As someone pointed out to me yesterday, “There’s an app for that” they are indeed correct.  You can get Police Scanner Apps for IOS and Android.   Guess where the feeds in those apps comes from?  If you said Broadcastify you’d be correct.  So if no one is feeding your municipality   then there will be no feed in the app.  We will be that feed.

So the assumption is that you have a Pi with Raspbian installed and you kind of know how to use it.

OP25 For Dummies – Or how to build a police scanner for $30 (Part 1)

OP25 is a program that decodes P25 Phase 1 and Phase 2 digital radio.  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.   The only things that do Phase 2 are hardware scanners and hardware radios and OP25 for software radios.  Bear in mind Phase 2 could be encrypted and nothing you can do will decode it.

OP25 is HARD.  I’m a geek and I messed with it on and off for a year or more and it whipped me more than once.  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.  There are tutorials out there, some good but everybody leaves out the good stuff or the stuff they took for granted.

First you need to download the latest Raspberry Pi Raspbian OS from here.  Get whichever version you want but I like to get the desktop version so I can VNC into it as it makes it easier.

If you have never done this connect your Raspberry Pi to a monitor, keyboard and mouse.  If you are an old salt with Linux then just run headless and SSH into your Pi.

Once you download that file UNZIP IT.  UNZIP IT.  The file will end with an extension of .img

Do NOT try to burn the zip file to your SD card.  UNZIP IT AND GET THE .IMG FILE.
