OP25 Miscellaneous OP25 (Osmocom) Questions

[Outerdog]

There's a possible fix for the loud noise at the end oh Phase II transmissions posted here:

poss. fix for tailing audio artifact p25p2 · osmocom/op25@dd830a1 .

So how do we apply this update? I don't see way to download the new p25p2_tdma.cc file.

~$ cd op25/build

~/op25/build$ sudo make uninstall

~/op25/build$ git pull

~/op25/build$ cd ..

~/op25$ ./install.sh

git pull output:

Still having issues with the git pull part:

 

[Outerdog]

That shouldn't be happening unless you made local changes to those files listed.

If you did change them, then well...

https://www.git-tower.com/learn/git/faq/git-force-pull

 

[CanesFan95]

Based on that link, git reset --hard seemed to help and git pull ran with no errors. But then ran into this issue with
./install.sh:

 

[lwvmobile]

run git pull inside of the main op25 folder, and not inside of the build folder

 

[CanesFan95]

Tried that and still had issues. So I figured eff it and re-installed Ubuntu and did a fresh new install. Now it's working and that squelch tail type noise is gone. Sounds much better!

So in the future, I'm wondering if it's better to just uninstall OP25 and so a fresh re-install to get updates. Can anyone advise what the commands would be to do this? Thanks.

If you want to reference a source ID tags file, which column should it go in and what should the header title be:

 

[Outerdog]

If you want to reference a source ID tags file, which column should it go in and what should the header title be:

It's a comma separated value for both file names. In other words, two file names in the TGID Tags File field, separated by a comma. First one is talkgroups, second one is subscriber unit tags.

Like so:

"Sysname"    "Control Channel List"    "Offset"    "NAC"    "Modulation"    "TGID Tags File"    "Whitelist"    "Blacklist"    "Center Frequency"
"EBRCS CCCO Central"    "774.45625,773.90625,774.18125,774.73125"    "0"    "0x1F5"    "CQPSK"    "ebrcs-tg.tsv,ebrcs-su.tsv"

 

[CanesFan95]

When you change settings in the Config tab, how/where are those changes saved? If those changes are saved somewhere inside files like multi_rx.py, rx.py, etc., then won't that mess up the git pull when you try to update?

 

[CanesFan95]

I'm noticing sometimes when you hit the GO TO button in Osmocom, enter a TGID, and hit OK, it'll just scan and not go to the TG. It's almost like the equivalent of just hitting the SCAN button. It only does this once in a while and I can't nail down why or when. Then you have try again a 2nd time to go to the TG.

 

[CanesFan95]

Sometimes the frequency activity will briefly show the same talkgroup on 2 different frequencies at the same time:



(Not a complaint, only an observation). And when you hit SCAN, it shows last command as SKIP, I believe that's meant to say SCAN:

 

[CanesFan95]

How do we get the radio ID colors from your .tsv file to show in the main display?



Sometimes it'll briefly flash the proper color:



But then it goes right back to the aqua blue default. These are my settings:



It works in the frequency activity and call log:

 

[Outerdog]

The SKIP vs SCAN text is just that "skip" is the word that was previously used. I changed the button to SCAN and never changed that message, which originally was just for testing/diagnostics. But it didn't seem to hurt leaving it there.

The "duplicate" in the active frequency table... it comes from the "backend" OP25 that way, best I can tell.

I've noticed some irregularity with the color display as well, but for me it is infrequent. When I see this occur, the ui is usually late in applying the correct color as opposed to reverting to the default after the correct one is already there...

There are many little things about the HTML interface which need to be tweaked. Overall it functions well, but we certainly didn't have much cross-browser cross-platform testing. And as I've said before, the whole thing is just a hack.

 

[CanesFan95]

Well overall, that's an awfully good hack !

 

[CanesFan95]

Does OP25 let you hear P25 private calls?
