op25

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

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...
