UBUNTU op25 help

Operating System Ubuntu 18.04.1 and then did a dist-upgrade so it is the latest.

I have op25 installed just not working.

I do believe something is wrong in my TSV files. They are attached in a zip file.

I live in Carroll County, MD and this is where I got my information.
https://www.radioreference.com/apps/db/?ctid=1194

The NAC was already filled in from the default trunk.tsv file that came with the program. I have no idea what NAC # I should be using or how to figure that out.

It executes using either my RTL-SDR or my HackRF. I just cannot get it to execute correctly for my frequncies and to play any sound.

Any help would be appreciated.

Your trunk.tsv appears to be incorrectly formed.
Try this set of data files: https://drive.google.com/open?id=1Luff2OCFwVTzRkIvtQIb7sTE9ofGFqWV

Note: you generally only need to specify the primary control channel unless the system switches to the backup on a regular basis.

Thank you -
Just tried your files and it gave a voice for like 3 words and then nothing. I am excited to see this work and the fact I got that was a great start.

So now my config are the files you gave me - any other help is appreciated.
Thanks

Using 852.9375a instead of 852.475c makes a lot happen on the screen just no voice -- alot more I have gotten yet - just need voice now

screen shot -
a lot more than I was getting now just no voice / sound

again thank you so much for getting me this far

Saw your post on face book. I am posted something there for you.

Not a whole lot to go on without logs etc. It appears you are locked on to a control channel because the tsbk counter is non-zero. It should be counting up regularly/continuously.

Bear in mind that I configured your files with a whitelist using the tgids you'd originally included. This means that ONLY traffic on those specific tgids are going to play audio. For diagnostic purposes it may be more useful to temporarily eliminate the whitelist so that you can decode any/all traffic on the system. Simply remove the filename reference from trunk.tsv or make it an empty file.

Depending how things are working (or not) you may find it useful to increase the logging level (-v 10) in the op25.sh startup script. The output will be very verbose, but contains a wealth of information for debugging purposes in the file stderr.2

Everything seems to be working except sound. I installed it on 2 systems now.

DELL Laptop
Installed: Ubuntu 18.04.1 LTS (This is the one you been helping me with)

Raspberry Pi 3
ubuntu-mate-16.04.2-desktop-armhf-raspberry-pi (Tried this to see if it would be different)

The sound card works with everything else. Just no sound when using op25.

Any advice would be awesome - thank you so much

Add "-U" to the command line options

What dongle are you using? Do you know its ppm?

Thank you it works

RTL-SDR.com dongle and still learning so unsure what is PPM?

Not to familiar with those as I have cheap china **** dongles, an airspy mini and 3 nooelec dongles. The china crap, 1 is off by 77 ppm, and the other by 38ppm,. The airspy was dead on and the nooelec are 0.5 off but so close I never really had any trouble with them.

Ppm is a parts per million setting. Its like fine tune. Not all dongles are dead on freq. Some ore slightly off. So by knowing if your dongle is slightly off freq, and determining by how many ppm, that can help reception somewhat. Most sdr progs allow a ppm value to be set for dongles that are off freq. Op25 also allows for this but since I only use the airspy and nooelec's that are dead on, I do not enter a ppm.

If your setup is running, go with it. If you suspect your dongle may be off freq, try looking at this. https://davidnelson.me/?p=371


I am not a huge linux user but after the help of some very knowledgeable users on this site, I got ubuntu up and running with op25 (boatbod fork) , trunk recorder and gqrx. These linux guys really know their stuff.

Mine is this one

Thank you for the info

Now that I have it working with op25 now to expand to others. Truck anything is all new to me. I am good at Linux but really new to SDR

Lol, you picked the toughest one to try first but it's also the best at p25 ph2.

thank you for all your help
