op25-boatbod

DES-OFB traffic decryption (known key) is now supported on boatbod's fork. How to get it working? - Define key variables (16 hex chars) in the key file (such as example_keys.json). Make sure to specify 0x81 as algid. - Authorize encrypted traffic sync by specifying crypt_behavior as 0 or -1...

Hi, I've recently gotten the RTL-SDR V4, and I have everything setup "correctly", however every time I run the command ./rx.py --args 'rtl' -N 'LNA:47' -S 2500000 -x 2 -f 857.2625e6 -o 17e3 -q 2 after a reset of the system or closure of the terminal I get the message ModuleNotFoundError: No...

I'm trying to run a weird experiment where I have a recording of an entire segment of a voice channel of a p25 system in my area and I'm wondering if I can demodulate it with op25. This is my current setup that is not working does anyone have any suggestions or am I doing this all wrong? I want...

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...

Is there any documentation for OP25? Specifically the boatbod version and mulit_rx.py? The git repo readme is kind of sparse. thanks!

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...

Dear Fellow Scholars, In scouring the forums, I found a user that was able to give an example liquidsoap script for separating TWO "channels" (defined in multi_rx.py json) into left and right channels for ONE stream (please see the post here). Seeing as most mobile devices (tablets, etc) are...

I'm running OP25 on a DragonOS vm with two RTL-SDR dongles trying to recieve the Anne Arundel smart zone system. Currently when I run the program I only get humming sounds coming in and out. My two dongles are definitely detected by the program. I run op25 with the following syntax...

G'day all, I come to you with cap in hand, as this is really getting frustrating. I can successfully get OP25 working using rx.py, but I would like to use multi_rx.py so that I can add radio ID tags. I have gotten it running, and it is decoding control channel data, and seems to be following...

Hi first post here! Looking for some assistance getting a single channel non-trunking frequency to work. Our state police just went digital 460.3000 unknown NAC thus far. I have been trying to get this to work with OP25 on Ubuntu. I have thus far got OP25 boatbod installed. I am able to get it...

I am trying to use OP25, but I am very lost. I am trying to monitor the Salem, OR P25 system. I am mostly worried about 4 talk groups (my agencies dispatch/working channels). The radio reference DB list several control channels, and also several black channels. how do I go about setting this...

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...

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'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...

I'm curious of it's possible to B-List individual radio's on a P25 system with OP25 Boatbod. A few members of a very special FD are just a bit much to listen to, so I want to block the UID's of their radios.

I have been building a mobile scanner (based on a Raspberry Pi 3, RTL-SDR and a touch screen) for the past year to monitor P25 trunk communications using OP25 (Boatbod). The used script is multi_rx.py and it works flawlessly around LSM. I modified the web interface so that it fits on a 3.5"...

I've been trying to fine tune my Nooelec NESDR Smart XTR to track the local Harris P25 P2 trunking system using boatbod's op25 fork and have just about exhausted everything I know to try (having followed Boatbod's guides and suggestions in other threads). I'm having issues getting the control...

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
