op25

I am looking for the following dashboard for OP25. When I run my web interface with Boatbod, I get the usual green/white interface. I am looking for instructions on how to have it display the this one: Thank you in advance!

OP25 is very configurable and I think that for me this is adding some confusion. I am attempting to configure a P25 simulcast system which includes some TMDA talk groups. The site I am trying to configure has 12 frequencies with 3 of them configured as control channels. The split for the...

I upgraded my Rpi 3B+ to Bookworm. I've been able to build Boatbod's version of OP25 pulling the gr3.10 branch with no issues. This works great. I've tried building the Osmocom version of OP25 from a fresh install of Raspi Bookworm both 32 and 64 bit. I get tons of build errors, not...

BLUF: Why can I receive a P25 channel regardless of the modulation type (C4FM vs CQPSK) but while scanning the radio will only land on this channel if the modulation is set to CQPSK? ~~~~~~~~~~~~~~~~~~~~ I have an Astro Spectra that mostly gets used as a scanner for conventional channels, a...

Hello RR, Currently exploring OP25 and I have some question in regard to the log output. Questions: The number at the end of the IMBE line after errs are the number of error in the line ? What is "prepare" after p25_crypt_algs ? Thanks

Hi everyone, I've been using the boatbod version of OP25's rx.py to listen to Seattle's PSERN with no major issues for some time but wanted to see if I could improve the performance by adding a second SDR and moving up to multi_rx.py. However, I am not hearing any audio and the decode rate has...

My other thread was getting real long and convoluted so I decided to start a new thread. First off let me apologize I'm not retired and I typically work 60-70 hours a week so I have a small window to work on op25. What makes it so frustrating is that its supposed to be easy and user friendly but...

Hello all, I am running OP25 on a Pi 3B and sometimes OP25 bugs. I was able to catch that in the stderr file this is what I found: 09/23/23 17:23:10.515841 [0] releasing: tg(50003), freq(772.256250), slot(1), reason(duid15) 09/23/23 17:23:11.738840 [0] voice update: tg(50003), rid(0)...

Hey all, so this question is directed at @boatbod or maybe someone who has played with his fork of OP25 and figured out these questions. So running on latest LTS Ubuntu(i5, 16gb ram, ssd, external graphics, basically overkill), the 2 system 2 cfg json with dual sound cards piping one system to...

I'm trying to create a channel configuration for a Tier II DMR channel using OP25 (Boatbod fork). I'm not getting any audio but it seems I am getting sync (looking on the sterr.2 file, see attached). This is what I'm writing on the terminal: ./multi_rx.py -v 10 -c dmr_channel_test.json 2>...

Can't seem to get alpha tags to show up and I'm guessing I'm missing a step. Watching the liquidsoap logs I'm getting metadata update error 404. Any Suggestions?

I recently built a mobile radio scanner to monitor P25 trunk communication systems based on OP25 (Boatbod). I have been working on the project for 3 years and am finally happy to say that it's done! I am using a NooElec SMArt v3 dongle as hardware, Raspberry Pi 3B for signal processing, 3.5"...

I am having an issue with OP25 (Boatbod) that it crashes mid conversation at random times. Sometimes it runs for 3hrs without any issues and sometimes it crashes after 10 mins. I added below a copy of my stderr.4 file (I had to cut some parts because the message was too long) Using Python...

How can I increase the control channel hunting speed on OP25 (Boatbod)? I programmed a lot of frequencies and would like to increase the hunting speed in order to make it more efficient.

Hi everyone! Since I've received many messages asking about the implementation of ADP decryption in OP25 (Boatbod), I decided to post it publicly here. I also received some messages stating that my code didn't work in the latest versions of OP25, therefore it wasn't possible to rebuild the...

I upgraded Ubuntu 21.10 LTS to 22.04 LTS (running it on a VM) and now OP25 crashes. I opened the stderr file and found this: Using Python /usr/bin/python3 Traceback (most recent call last): File "/home/pi/op25/op25/gr-op25_repeater/apps/./multi_rx.py", line 55, in <module> from gnuradio...

The goal is to create a setup guide with complete exact steps to get OP25 working in Windows. This is a first draft (attached) to be revised based on input from: Current OP25 users Those who've never used OP25 OP25 developers, contributors, and other experts. After revisions, the draft can be...

I'm trying to create a start interface where a user can select systems he wants to monitor on OP25 as an add-on. Basically, the buttons on the interface will launch a command script on the terminal which will start OP25 on the selected system. I designed the interface but now need help to...

I'd like to add ADP decryption capability to OP25. I have been doing research for a while about RC4 cipher (a.k.a. Motorola ADP), so I do know how the cipher works. I have some experience programming in C, so I'd like to know where I should start. It would be great if Boatbod gave me a hand with...

What libraries are required to allow Op25 plots to work? I have successfully operated Op25 on Ubuntu-16, but now am operating on a much trimmed Linux distribution and am obviously missing a library or two. Op25 will start up normally, but will not bring up any of the plots when an appropriate...
