One thing I've noticed is when clicking "Go to" and entering a talkgroup, when you are already holding on a talkgroup, OP25 simply resets to scanning, requiring you to "Go to" and enter a talkgroup again to actually switch between holding on different talkgroups just using the Go To button.

Yep - this is in the next fix, along with these little gremlins:

's' key scan/skip not working, 'h' key hold not working, 'l' key lockout not working (already pushed to repo)
Fixed "Secondary Control Channels" display issues
GO TO fails when already HOLD active
Source columns in Events table were not showing colors
Improved how rx_update, chage_freq, trunk_update are displayed in the Events table
"Restore Defaults" button in Config

I will start looking into the memory issue. I have seen similar problems w/ Firefox and Win 10.

Thank you for the feedback.

Things are good enough right now that I'm probably going to bundle OP25 into the Broadcastify RPi image here soon and wrap some wizard/provisioning around it.

Looking for a link that would help a new user in how to install OP25 and associated required software. From what I have read I don't have any experience in using Mint, Linux of ubuntu which seems to be the operating system of choice. I did try this site: [How to Install Ubuntu 18.04 {Tutorial With Screenshots}] and what the site said I should be seeing wasn't what I seeing.

Thank you in advance.

Looks great maybe I will give it a go now that it looks this way.

hdphil · Aug 14, 2021

could someone point me to find the " README-July-2021 " file?

i didn't see it in
op25/README at master · osmocom/op25

maybe i'm in the wrong fork of the internet,

I've been running BoatBod version, i would like to give this a try.

is their any installation help for This?

you can find a copy of that README at this link - it will also be in the repo (if and when you clone it) at the same path as suggested by the URL

README-July-2021\apps\gr-op25_repeater\op25 - op25 - Osmocom OP25

i'm having issues with the "sude make uninstall"

changed "sude to Sudo

Code:

pi@pisdr:~ $ cd op25
pi@pisdr:~/op25 $ sudo make uninstall
make: *** No rule to make target 'uninstall'.  Stop.
pi@pisdr:~/op25 $

or should i just delete my current op25 directory (backed up'ed of course?

KA1RBI · Aug 14, 2021

you need to be in the "build" subdir - and if you nuke the current op25 directory before doing the uninstall then you lose the ability to easily uninstall the current version.

Try replacing your first command listed with

Code:

cd op25/build

You would need to once again be in the home directory before starting the sequence.........

ok, thanks, that worked, I'm starting on "the installation sequence"

Code:

pi@pisdr:~/op25/build $ cd ..
pi@pisdr:~/op25 $ cd ..
pi@pisdr:~ $ git clone https://git.osmocom.org/op25
fatal: destination path 'op25' already exists and is not an empty directory.
pi@pisdr:~ $

I get that same error after doing the sudo make uninstall with

Code:

git clone https://git.osmocom.org/op25

When attempting to clone the repo, git attempts to create a directory named 'op25' to contain the local copy of the repo.

In this case there is already a directory with that name.

You can create a new, blank directory, then 'cd' to that, then repeat the 'git clone' command.

If successful, you will now have two separate copies of the repo, one directly under your home directory, and the second, new one under the directory you created.

You will need to **beware** of the fact that there are now now separate repositories on the system, both named 'op25' - and when changing directories using the 'cd' command you *will* need to be cognizant of which of the two copies you intend.

You could also nuke the "old" copy of op25 (after uninstall) but nuking things can be dangerous, potentially. Nuking also makes it somewhat harder in the event you want to switch to the old version....

Max, i finally got it working. here were my steps.

fresh os on a spare MicroSD card for my raspberry pi (all the updates as well)
installed GQRX to check out the SDR (checked the local WX report)
installed BoatBod op25, and Icecast / LiquidSoap, used my existing Liquidsoap/Tsv files from my currently working op25 system. so this proves everything works from the sdr to the VLC player on my desktop.
Then performed the uninstall

Code:

pi@raspberrypi:~ $ cd op25/build
pi@raspberrypi:~/op25/build $ sudo make uninstall

Opened another terminal to start Liquidsoap:

I do get some errors, but i get the correct display at http://127.0.0.1:8003/ and i hear audio through my VLC player
Things i still need to do, try the -X for freq control, and is it possible to display the tuning plots?

So all of my old settings and configs seem to work fine. so far the only setting I'm missing is the tuning scopes

Thanks for your help,

Philip

It's based on GNU radio which is an open source platform, open source projects like OP-25 are fundamentally incompatible with windows by definition.

Are you saying that open source software is fundamentally incompatible with Windows by definition?

Considering your somewhat terse response, it is worth pointing out that a number of solutions exist to run OP25 on Windows. The easiest of these are VirtualBox -- open source software for Windows (!) -- and Ubuntu Linux running under that.

i was able to get the constellation pattern to show, just added -P to the command line

The "P" key toggles it on and off, although the update time is pretty slow, another thing i noticed, running HTOP , this single instance pretty CPU intensive compared to my other setup running 2 instances of op25, on the same trunk system for 2 difference sets of talkgroups. their are probably many settings i could change to help it out, both PI's are the same , using Msata SSD drives. execpt the PI running 2 instances of op25 is also running as a file server, and soon with Pihole...

Couple of points for you.

The "P" key shows/hides the display in the Web UI. It does not actually stop the plot from being created by OP25 (gnuplot). So the CPU cycles for the plots remain if the display in the UI is turned off.

The update interval is 1.0 sec and can be reduced in rx.py or multi_rx.py if you wish. Personally, I run it at 0.6 sec.

The data stream is sending more information over than the boatbod version does and you may take some CPU hits because of this compared to boatbod. Separate from that, we are trying to sort out a potential memory/cpu issue with the Web UI which seems to be intermittent. Hopefully, we should have an update for that very shortly. Although as I look at my browser running OP25 Web UI locally it's sitting at 8% of the CPU and 856 MB. Pretty normal....

Pi-hole isn't particularly resource hungry. Just watch out for port conflicts (there are no conflicts with the defaults set from both apps).

krutzy · Aug 17, 2021

Philip,

I tried to duplicate your steps with regards to the boatbod installation. You show the detail of each step. However when I get to your step 13 you are just doing a git clone which results in the "destination path 'op25' already exists and is not an empty directory.". You don't show how you got around this. It appears you just cloned it on top of the old one without the need to create a new separate directory.
I would like to know how you did it?

Kevin

hdphil · Aug 17, 2021

Kevin,
I used "sudo file manager " and save my important config files, liquidsoap, tsv, and op25.sh contains the rx.py setup information. to another folder, then did the uninstall, deleted op 25 and started over..copied the important files back .

Thank you very much, now that makes more sense!
