We are seeking testers and feedback on the new release candidate which has been posted in the Osmocom master repository. You can post to this thread, start a new one, or PM me.

The killer new features I'd say are multi SDR support for simultaneous voice and control channel decoding, sql logging, and the new customizable Web UI. The new detailed sql logging offers some unique possibilities for low power remote logging scenarios.

At this time I'd like to give a special shoutout to OP25 Contributor Triptolemus without whose work this release would have been impossible.

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

Screenshots below.

Forgot to include list of some of the highlights

Code: 
1. With thanks to OP25 user Triptolemus, the web client is enhanced to
   include comprehensive logs of recent control channel signalling and
   call activity.  Many other features are also added:
    * unit ID (subscriber ID) tagging - similar to the existing TGID
      tags setup.
    * tag color coding (for both TGID and SUID tags).
    * tag ranges and wildcarding - for both the TGID and SUID tag maps,
      a single definition line may be used to create tags for a range of
      IDs.
    * real time system frequency status table
    * smart colors
    * user settings (colors, preferences) may be edited and saved via a
      convenient set of web forms and applications

2. The multi_rx app adds extensions to include trunked P25 call following
   concurrent with full-time tracking of one or more P25 control channels.
   If necessary, additional SDR devices may be configured to allow full
   coverage of all control channels without loss of CC data even during voice
   call reception.  Several new command line options to multi_rx have been
   added - -T (trunking TSV file) -l (terminal type) as well as -X and -U,
   all having the same meaning as in rx.py.

3. Control channel logging to SQL database is added.  For details see the
   section on the Flask Datatables App, below.

4. Experimental TDMA Control Channel support

Ok, thanks, but using VM, will it hamper the performance of the program? Sorry for all the questions, but this is a great looking program

No. It will run perfectly in a VM.

One of the motivators behind a web-based UI is so the client can be OS agnostic. In other words, you can start OP25 in a Linux VM, minimize it, then interact with it using your favorite web browser on your preferred OS.

Thank you, I'll give it a try. This program has great organized GUI, plenty of information about the system to be viewed in a great presentation

Oh really, so I thought you had to run Firefox inside of Ubuntu inside of VMWare.

No, not at all. When starting OP25 and setting the http server as active, set the ip address as 0.0.0.0:8080 and it will open the server to the local network.

I have my start files in a little shell script that looks like this:

Bash: 
#! /bin/sh
echo "starting OP25 2 - 2 Receivers..."
echo `date`
l="-l http:0.0.0.0:8080"
./multi_rx.py -c sys/cfg-trunk2.json -T sys/ebrcs.tsv $l -v 1 -U 2> stderr.2

Discriminator audio is supported in rx.py.

Not my area of expertise, but there's a thread I found here with a quick search... I'm sure there are more.

OP25 with Discriminator Audio Question

I've added a discriminator jack to my BCT15x and I am able to decode p25 easily with DSDPlus. I would like to do the same with OP25 so that I can decode on a pi4. However I have not been able to figure out if OP25 has an option for accepting discriminator audio via the microphone jack. I have...

Wow, this is the bomb! What a great package, stupid question to ask, but will tis run on Window 10?

You may have some luck runnning it inside WSL (Windows Subsystem for Linux), but given you had to ask, I'd say getting that to work might prove to be a bit tricky for you unfortunately.

Practically all of the development work in recent years (the past 8-m years anyway) has been focussing on SDRs, primarily the RTL-SDR. I'd say that using a discriminator tap would prove to be somewhat limiting/disappointing, espcially for trunk tracking/LSM/CQPSK/Phase 2 usage.
