op25-boatbod

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

Hey again all. I am so close to having my OP25 fully set up, but I am running into one final issue. I constantly get PCM Underuns when listening to A Motorola SmartZone™ System using multi_rx.py and I dont know why. Let me know anything you need form me, logs, start command line etc. Thank all...

Hey all, I'm loving OP25 and use it to monitor Multiple Counties in areas that I take my Pi with me to, and was wondering if I could make folders for a Specific Area. for example: In the main op25/op25/gr-op25_repeater/apps folder I would have: County1.sh County2.sh and then I would have folders...

Hello. I'm doing research about P25 Common Air Interface and encryption protocols. I'm new to using OP25, so please be understandable if I'm wrong about something. When I turn the logging up to -v 10, I can see the codewords and all the other info, but it's all messy. I think I'm missing...

Hey there everyone. I was wondering if it would be possible to truly track a OP25 Simulcast system using multi_rx.py. Like just have one SDR Stay on the control frequency and have the other Tune around. Let me know if this is possible or if Im just crazy. Right now I have it set up but its just...

Hi, I did a fresh install Ubuntu 18:04, updated, upgraded. Installed Op25 boatbod, sudo apt-get install gnuplot-x11, was able to get Op25 running. Then I added -l http:0.0.0.0:8080 Op25 does not run. take out -l http:0.0.0.0:8080, and it runs. What am I missing to get it to run with GUI? I...

I am searching for some hints on how to get working OP25 (Boatbod version - downloaded from git a couple of weeks ago) on a Raspberry Pi 3 running Raspbian Buster. The signal is received using a common RTL2838 usb key. My goal is to decode a DMR unencrypted signal on the Raspberry and play the...

I have overhauled the boatbod op25 install script and cmake build environment to auto-detect available gnuradio package version (3.7 vs 3.8) and make the corresponding python selection. The previous method of apply gr3.8 patches has been eliminated so there will no longer be locally modified...

Hey Guys! In the last week or so all of my OP25 radios tuned to 773.84375 have stopped receiving. Could anyone check if that frequency is active still? I've tried multiple backup frequencies and still hit nothing. I've tried several different SDR dongles as well. Here is an example from the...

For the past couple months I have been brewing a significant update to op25 with a lot of help from members wgbecks & maus92 along with some generous folks in the background how allowed me to run development code on their systems in MD and NJ. As a result I am pleased to announce that the...

Just wanted to thank Boatbod for all he does for OP25 and the users. His great documentation and endless support in the forums made it all possible for me and I assume many others who never say a word. It works so good now. I'm still impressed. He doesn't talk down to all us idiots who are...

I just added the ability for op25 to send sound to the PulseAudio system in lieu of ALSA. This may or may not be a good thing depending on your Linux system as it seems some - notably RPIs of varying flavors - have issue with Pulse permissions, particularly it seems when you are running them...

In an effort to make it just a little bit easier for people to set up their trunk.tsv files, I have created a small helper application called "cfgtrunk.py" which facilitates changing parameters without having to use a text editor. It's far from foolproof, but is easier than vi and less error...

Hey, Thanks to boatbod's setup, OP25 is running nicely on an old laptop I had running Ubuntu 18.04. The only weird issue is that it seems like the SDR's noise floor's do not change significantly when messing with the -N 'LNA:xx' setting in OP25. The noise floor from what I have seen in GNU...

I'm in an odd situation.. our dispatchers all of a sudden got QUIET and they have been for a while now. The agencies haven't said anything to encourage them to raise the volume or anything, but they are hard to hear both on OP25 and my SDS100. Is it possible to increase volume by their radio...
