op25

I have ported Max's recently announced "-X" tracking code to the boatbod op25 repo. After experimenting with it a bit I changed the way the frequency corrections are handled so that it utilizes the source device's ppm correction then makes residual fine tuning adjustments much as if you had...

Hi Guys, I ‘m running this on rapsberry pi and I ‘ve tried the following and they come up with very similar results. It will run for 1-15 minutes and then start throwing tuning errors. Please help! Here are the two I‘ve tried so far: ./rx.py -l http:127.0.0.1:8080 --args 'rtl' -N 'LNA:47' -S...

I have new Project need some advice, I like to set up a broadcastify stream, I have an Airspy R2 SDR our local police uses P25 Phase 1 trunk system they will be switching over to Phase 2 in June of this year, I'm looking for something where I could use a Raspberry PI with Sdrtrunk or OP25? like...

I am trying to receive 700Mhz Nationwide Interoperability Channels on my Raspberry Pi3B with OP25. Since these channels, such as 7CALL50 are P25 simplex RX channels with NAC 0xF7E, is that possible to do with the existing hardware and software that I have? I don't want a heavyweight or resource...

When using ./multi_rx.py dmr_rtl_example.json to recieve DMR, I get this error: Traceback (most recent call last): File "./multi_rx.py", line 402, in <module> rx = rx_main() File "./multi_rx.py", line 384, in __init__ config = json.loads(open(options.config_file).read()) TypeError...

Okay don't laugh too hard! :) I have an older version of OP25 running well. I want to update to the latest version to be able use the web interface feature. What terminal commands do I need to enter to update OP25 without messing up what I already have configured and set-up? Thanks!

I'm running OP25 made with Boatbod's build in an Oracle Virtual Box VM running Ubuntu 19.10 Desktop. I also have OP25 running on a Raspberry Pi4 with Boatbod's build under Raspian Buster Getting both running wasa snap thanks to Boatbod's build. I am attempting to monitor multiple...

Who currently make the most frequency stable RTL-SDR? I'm considering setting up Trunk Recorder for 800 MHz range and wondering what dongle has the least amount of drift over time and temperature. Thanks!

Hey all, OP25 is an awesome product. I'm working to change my feeds over to this from a BCD996P2 because it's so much better on our system. OP25 and Liquidsoap run beautifully from the terminal but fail miserably as a service. I have an RPI 3B+, RTLSDR, and am running Raspbian Stretch...

Is there any way to assign multiple RTL-SDR dongles to a single running op25 instance when the talkgroup frequencies are over 3 MHz +/- from the control frequency? If not, is there another way to handle this w/ op25? Are people just using supported SDR with a larger bandwidth that is affordable...

In OP25, there is a file called multi_rx.py. On lines 114 - 115, there is a section of code: if config.has_key('key') and (config['key'] != ""): self.set_key(int(config['key'], 0)) This section of code appears to have been introduced on May 6, 2019. It appears that it is...

I have been trying to install OP25 using Boatbod's git. I been hanging on 97% I have tried several times to redo the install and same result. I am not worried to much about this but just wanted to put it out there as an issue. This is on a Pi 3 A+ brand new raspbian 4.19. I have copied the log...

I am fully aware of THIS post and i have followed it multiple times, however whenever i reinstall op25 with ./install.sh i get the same error over and over again: osmosdr source_c creation failure Traceback (most recent call last): File "./rx.py", line 921, in <module> rx = rx_main()...

Followed the thread to setup OP25 to stream to broadcastify. I followed the config and am getting an error when launching darkice with the config. I am posting all of the config files. I am assuming that there is an issue with the sound card input/output on the Pi, just need verification from...

I have the service configured as noted in the thread "Setting up op25 to stream to broadcastify" but in my case I just need to have it start on boot. This will be a headless instance with speakers connected to raspberrypi. It will not be connected to the internet thus not sending signal...

Hello all! I am trying to get OP25 running on a Raspberry Pi Zero. I can get OP25 to run, and I can get the audio piped over the network to my desktop PC so I can hear it. However, I have to turn the sample rate for rx.py way down to get OP25 to detect any transmissions, and even then, it...

I have OP25 running and its incredible. I am having an issue though with underuns. Has anyone else experienced this and what can be done to fix it? Oddly enough, I can listen to one site with no issues. If I change to a different site, I get the underruns. Any help would be greatly...

Hello all! I bought a Realtek SDR from rtl-sdr.com a couple of years ago and played with it a bit at the time. I don't remember exactly what I tried, but it seemed P25 decoding was still pretty experimental then. Recently, I started playing with it again, using boatbod's version of OP25, and...

I've got OP25 (boatbod) rx.py working using an RTLSDR dongle, and the audio sounds great. Is there a way to simultaneously receive/decode more than one channel that falls within the RTL's 2.4MHz of spectrum being sampled? The two channels I'm interested in are not trunked channels. They were...

Putting this question out there to see if anyone has had similar thoughts. I have OP25 successfully running on a dedicated xUbuntu machine and have explored it thoroughly. But I was wondering if implementing talkgroup priorities would be possible. I imagine this would be implemented in...
