While I still remembered the steps it took for me to get OP25 running, I thought I would document them on my "John's Geekblog" blog. I broke it into multiple parts; part 1 is at http://blog.febo.com/wp/?p=158.
I would welcome any additions/corrections!
I also recorded a few minutes of scanning last night -- it was Friday evening and things were hopping so there are a number of missed messages. That video is at https://www.youtube.com/watch?v=_1jO3yM0MIA
You may note that my GUI looks a bit different than yours. I spent some time fiddling around to give more display space for the talkgroup tag. I have no idea what I actually did (WX GUI is incomprehensible to me), but I finally came up with a result that doesn't look too bad.
Thanks again for all the help!
John
Thanks John. I have been kind of waiting to see a name I recognize on this list. I played briefly with op25 7-8 years ago, and ran into so many problems ..
I have been wondering about getting op25 to run on a Raspberry Pi as a nice cheap solution for the simulcast public safety system here. I did recently learn of trunk-recorder from a Reddit post, which has Raspberry Pi install notes.
I think its time for me to give it a try again.
I wonder if the newest RPi has the horsepower as op25 takes quite a bit of CPU. If it works well, that really opens up some doors.

To be honest I don't think so, but I have a Raspberry Pi 3 laying around and a few spare RTL dongles as well as a spare HackRF that I'd be willing to put into service to see if this works.
Any recommendations on what I should install as far as OS? I'm guessing Raspbian with the latest image. From there I'll do a software update and attempt to install OP25.

I'd like to read from someone who has tried it with OP25. I know the DSD route is pretty much going to lead to undesired performance.
This is what I was referring to: https://github.com/robotastic/trunk-recorder https://github.com/robotastic/trunk-recorder
I remember them saying in the radio reference thread that he was using a send gen Intel NUC. I think that might be the low bar for what can decode this without under runs as it's CPU starved. But I'll make the attempt and document my approach.

So, after a little fiddling, it compiles. I am running the program right now with an RTL dongle and I'll let you know how that goes.
Install a clean copy of Raspbian https://www.raspberrypi.org/downloads/raspbian/ Jessie, then do the following commands.
- sudo apt update - sudo apt upgrade - sudo apt install gnuradio gnuradio-dev gr-osmosdr libhackrf-dev libuhd-dev git cmake build-essential libboost-all-dev libusb-1.0-0.dev libcppunit-dev liblog4cpp5-dev libssl-dev - mkdir ~/radio - cd ~/radio - git clone https://github.com/gnuradio/gnuradio - sudo cp gnuradio/gr-analog/include/gnuradio/analog/squelch_base_cc.h /usr/include/gnuradio/analog/ - git clone https://github.com/robotastic/trunk-recorder.git - cd trunk-recorder - cmake . - make
