op25

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...

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...

I'm tryin to get OP25 running on Raspberry Pi 4 with Buster. When I launch the app, my .tsv tgid file is not loading. I get the following errors: ./op25_millersport.sh Using Python /usr/bin/python2 gr-osmosdr 0.1.4 (0.1.4) gnuradio 3.7.13.4 built-in source types: file osmosdr fcd rtl rtl_tcp...

Again- thank you in advance for any assistance! Making progress here...but getting no audio. I must be missing something! I've got OP25 monitoring the control channel I want and it appears that liquidsoap is sending data to Winamp: Winamp is getting meta info from OP25 (the talkgroup is in...

Hello! First and foremost - thank you in advance for the help! I provide the DUCOMM Channel 1 East feed in IL on Broadcastify and am looking to improve it by using my RasPi (maybe include more talkgroups, etc.). I am trying to monitor STARCOM21 (Illinois; specifically the 774.43125 control...

Would there be any advantages to using 32 or 64 bit linux OS for OP25. My main consideration is sound quality. I am building First Responder home monitors using the old Zotac ZBOX-CI320NANO-P and SDR(s) with small antenna. I have the total price down to about $110 (including USB powered...

I've added a discriminator jack to my BCT15x and I am able to decode p25 easily with DSDPlus. I would like to do the same with OP25 so that I can decode on a pi4. However I have not been able to figure out if OP25 has an option for accepting discriminator audio via the microphone jack. I have...

Hi all, probably a really stupid question here. I had/have OP25 up and running great on my Pi3B (save the flaky USB port that boatbod helped me diagnose earlier). For various reasons, I want to move this to a Pi 4. Install went smooth. OP25 up and running. But I'm getting no audio. The web...

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...

I have been running the two different OP25 Phase 1 vocoders side by side and I am noticing some differences between the two. Pavel's fixed point vocoder sounds bit more natural to me and less robotic. Tones also sound nice and smooth. When I look the the waveforms in Audacity, the fixed point...

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...

Hi all, I'm very new to the space and just getting started. I've appreciated the resources here in the forums but I seem to have a problem that I've been struggling with for the past several hours. I have a RTL-SDR V3 hooked up to my Raspberry Pi 3B+ and have gone through the steps from here...

Hi All, Is anyone running the new version of OP25 (Boatbod's fork) in the SJ area? I would like a favor. OP25 has a log function that writes to a file and would like to review those details. thanks!

Good afternoon! This is my first post on the forums here so bear with me please. I have a Raspberry Pi 4 with 4G ram and have largely succeeded in getting OP25 installed, started, and tracking my local police P25 system. Despite it seeming to perfectly track transmissions and switch to the...

I'm considering adding a second dongle to my computer running OP25 and I'm having trouble finding the instructions to do this. Is running 2 instances of OP25 and having both outputs feed the same headphone jack very difficult?

I just discovered the OP25 priorty setting and it works great! I understand that Priority 1 is the highest and 3 is default. My question is, are 1,2 and 3 the only valid levels of priority? What is the range of the priority setting, is there a valid priority 4 or 5....? Thanks!

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...

I've had a complaint about an intermittent issue where audio is garbled, I'm including a link to see if anyone can identify what may be the issue. Google Drive Link to Example Audio Fresh install as of 5/26/20 running on pi4 with NooElec NESDR Smart v4 SDR ./rx.py --args 'rtl' -N 'LNA:35' -M...

I'm trying to diagnose some tuning errors and it would be nice if I could load the webpage on a remote machine. The pi is headless so I would have to connect it to a monitor. Is that possible at all? Thanks much!!!
