You're probably right. However, with the rtl:0 thing, the error message I was getting was ValueError: No JSON object could be decoded.
Nope, that one was caused by a spurious comma in your JSON
You're probably right. However, with the rtl:0 thing, the error message I was getting was ValueError: No JSON object could be decoded.
Once the audio has ceased, if you bring up the terminal screen do you see any activity:
- does the "tsbks" counter keep incrementing?
- do you see any activity on the bottom line where the Frequency displays along with TGID and Tag info?
- what log level are you running? what if anything continues to appear in the log?
Try running "top -H" in a separate window and see what threads related to op25 are active. (post a screen shot)
I confirm the link above dseven sent you. I was having similar errors.
The only way I was able to successfully compile OP25 on a RPI was this way`:
sudo apt-get update
sudo apt-get upgrade
sudo apt-get build-dep gnuradio
sudo apt-get install libboost-all-dev liblog4cpp5-dev swig cmake gnuplot gnuplot-x11
sudo apt-get install gnuradio gnuradio-dev gr-osmosdr librtlsdr-dev libuhd-dev libhackrf-dev libitpp-dev libpcap-dev git
REBOOT
cd ~
git clone https://github.com/boatbod/op25
cd op25
mkdir build
cd build
cmake ../
make -j4
sudo make install
sudo ldconfig
Hope this helps

Sorry for the delay, i finally had some time to sit down and gather some further info. I cannot seem to figure out when the audio drops and it always seems to be after running the server for a couple of hours. When i dont get any audio I still receive activity for the TGID and Tag info and i can see it actively following the voice channel. the TSBKS continue to rise and im not seeing anything other the the Voice Channel changes in the log. I will upload a video of both the browser and top -H command when i can.
I take it radio ID aliasing is still a no go? Last I saw it mentioned was 6+ months ago...
Hello all, after I read 108 pages and install Op25 I see the talk groups but I dont have sound

It appears (per RRDB) that all TGs on that system are encrypted.
Hello all, after I read 108 pages and install Op25 I see the talk groups but I dont have sound , I rewiev the log filew and in all time voice is update but after is time out.

Thanks for your help
The error sequence ("voice update" followed by "voice timeout") suggests that your op25 is decoding the control channel correctly but never obtaining a framing lock on the voice frequencies. This doesn't typically happen because of encryption, but usually because either modulation or ppm correction are set incorrectly.
The traffic seen is phase 1 (no slot id) but the RRDB entry suggests this is a phase 2 system, which almost universally means you should be running without the "-D fsk4" parameter (i.e. cqpsk mode).
How does the the mixer plot look? Is it nicely centered or do you need to make tuning adjustments?
Hello Thank you for your help y run in C4FM and in cqpsk without the parameter D fsk4 too my plot is centered this is a picture.
How could I scan multiple sites with the same NAC ??

Trying to help a friend in Canada set up op25 and his area is a little confusing to me. Is this compatible with your branch?
https://www.radioreference.com/apps/db/?sid=537
That's similar to Ontario's Fleetnet system; I use TRUNK88 (plus DSD+ for the digital talkgroups). Maybe check in the Prairies / Pacific Coast forum for someone who already has a working setup - they could just zip it up for you.boatbod:
