op25

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...

I'm only trying to tune into specific frequencies manually and decode their audio. I'm already doing this with gqrx and dsd, by broadcasting with UDP and inputting the data into dsd as such (it works just fine): socat udp-listen:7355 - | ./dsd -i - -o pa:1 I'm trying to do the same with...

Howdy All, I recently took over Development for Trunk Player and I am happy to announce myself (@maxwellDPS) and @NebraskaCoder are bringing life back to the project! Development is in progress This will be a complete rewrite of Trunk Player, all from scratch! The new version will be all API...

I really enjoy using the Op25 SDR software, so i decided to interface a oled display to show the Alfa Tags, I do like the different terminals programs from BoatBod and KA1RBI and all of the people that made this possible. I wanted a way to display the Alfa tags while my computer monitor were...

I bought a Raspberry Pi 4 (8 gig) to run SDRs on, and other stuff. I have 2 SDRs, a NoElec using an 820T chip, and a DVB with an 820T2. Have OP25 set up and working, but when I try the command line to get the NAC, I get several errors, starting with PLL not locked, and "value error, need more...

I would like to change my OP25 whitelist based on the time of day. I'm running a single instance of OP25 in terminal mode launched with the command line: ./rx.py --args 'rtl' -N 'LNA:47' -S 1000000 -o 25000 -T trunk.tsv -V -w -2 -U 2>stderr.2 --crypt-behavior 2 In the evenings, I change my...

Hey all, I was wondering if there was a way I could export the talkgroups that OP25 receives into another python file so I can use them for a project. Is this at all possible? I know I would have to import a file but dont know which one to use. Thanks Guys
