op25

Hey all, OP25 is an awesome product. I'm working to change my feeds over to this from a BCD996P2 because it's so much better on our system. OP25 and Liquidsoap run beautifully from the terminal but fail miserably as a service. I have an RPI 3B+, RTLSDR, and am running Raspbian Stretch...

Is there any way to assign multiple RTL-SDR dongles to a single running op25 instance when the talkgroup frequencies are over 3 MHz +/- from the control frequency? If not, is there another way to handle this w/ op25? Are people just using supported SDR with a larger bandwidth that is affordable...

In OP25, there is a file called multi_rx.py. On lines 114 - 115, there is a section of code: if config.has_key('key') and (config['key'] != ""): self.set_key(int(config['key'], 0)) This section of code appears to have been introduced on May 6, 2019. It appears that it is...

I have been trying to install OP25 using Boatbod's git. I been hanging on 97% I have tried several times to redo the install and same result. I am not worried to much about this but just wanted to put it out there as an issue. This is on a Pi 3 A+ brand new raspbian 4.19. I have copied the log...

I am fully aware of THIS post and i have followed it multiple times, however whenever i reinstall op25 with ./install.sh i get the same error over and over again: osmosdr source_c creation failure Traceback (most recent call last): File "./rx.py", line 921, in <module> rx = rx_main()...

Followed the thread to setup OP25 to stream to broadcastify. I followed the config and am getting an error when launching darkice with the config. I am posting all of the config files. I am assuming that there is an issue with the sound card input/output on the Pi, just need verification from...

I have the service configured as noted in the thread "Setting up op25 to stream to broadcastify" but in my case I just need to have it start on boot. This will be a headless instance with speakers connected to raspberrypi. It will not be connected to the internet thus not sending signal...

Hello all! I am trying to get OP25 running on a Raspberry Pi Zero. I can get OP25 to run, and I can get the audio piped over the network to my desktop PC so I can hear it. However, I have to turn the sample rate for rx.py way down to get OP25 to detect any transmissions, and even then, it...

I have OP25 running and its incredible. I am having an issue though with underuns. Has anyone else experienced this and what can be done to fix it? Oddly enough, I can listen to one site with no issues. If I change to a different site, I get the underruns. Any help would be greatly...

Hello all! I bought a Realtek SDR from rtl-sdr.com a couple of years ago and played with it a bit at the time. I don't remember exactly what I tried, but it seemed P25 decoding was still pretty experimental then. Recently, I started playing with it again, using boatbod's version of OP25, and...

I've got OP25 (boatbod) rx.py working using an RTLSDR dongle, and the audio sounds great. Is there a way to simultaneously receive/decode more than one channel that falls within the RTL's 2.4MHz of spectrum being sampled? The two channels I'm interested in are not trunked channels. They were...

Putting this question out there to see if anyone has had similar thoughts. I have OP25 successfully running on a dedicated xUbuntu machine and have explored it thoroughly. But I was wondering if implementing talkgroup priorities would be possible. I imagine this would be implemented in...

Is it possible to use OP25 for analog/digital mixed systems. Like Fleetnet Ontario or Fleetnet Manitoba, if so what is the NAC I use or command line argument?:confused:

im tryimg to follow LAPD trunked systems but cant seem to find the TGIDs and Alpha tags to do so. im very new to OP25 but understand to follow trumked communications the TGID and Alpha tag is all i need i can see all the LAPD frequemcies but hardly any TGIDs can anyone familiar with usimg...

My son is a firefighter for MoCo ESD1. I live a stones throw from main station 91 or about an eighth of a mile from I45 on FM1097 west. I'm primarily interested in listening to fire/EMS in my area but I want to be able to pick up as many of the transmissions as possible. Anything out of my area...

Hello: I am looking for a reasonably priced system to install Ubuntu and OP25 on to monitor a couple of P25 systems. I'm enjoying the computer-based scanning experience with DSDPlus on Windows, but it doesn't look like op25 will cross-compile (at least I don't see anyone having done it) on Win...

Hi, Here is a brief summery of the process that I used to create a USB boot drive, based on the excellent GNU Radio live environment, to run op25 (scope.py, etc...). The whole process should take less than 15 minutes, resulting in a bootable GNU Radio environment that is pretested, integrated...

Hi, I thought that I would post a brief summary of the process that I used to create a bootable USB drive to run OP25. Hopefully others may benefit. Assumptions: - You know how to boot from a USB drive - You have at least a cursory familiarity with Ubuntu, including how to setup networking...
