OP25 OP25 No Audio output.

[VA4JOE]

Hi there,

I have installed OP25 on my Debian Bookworm system, but it seems no matter how much I try I can't get it to output audio.
I use the following command:

./rx.py --args 'rtl' -N 'LNA:47' -S 2500000 -x 2 -f 770.19375e6 -o 17e3 -q -2 -v 5 -T trunk.tsv -O hw:1,0 -w -2 -U 2> stderr-stream0.2

I get a screen that shows 4 voice frequencies and so far about 10 unknown talk groups. The tsbks keep going up.
This is the output of part of my stderr-stream0.2 file

Not sure what the problem is but I'm crawling the walls and tearing my hair out trying to search for and find an answer.

I am not familiar with the debian Bookworm OS but you might want to try directing audio to use the default Linux sound device by using
the -U command line argument for op25 instead of -O hw:1,0 to let the operating system decide if the sound device accessable under ALSA
or in its actually under control of Pulse Audio.

It is in the command I used near the end.

./rx.py --args 'rtl' -N 'LNA:47' -S 2500000 -x 2 -f 770.19375e6 -o 17e3 -q -2 -v 5 -T trunk.tsv -O hw:1,0 -w -2 -U 2> stderr-stream0.2

I changed it to this:

./rx.py --args 'rtl' -N 'LNA:47' -S 2400000 -x 2 -f 770.19375e6 -o 25000 -S 8000 -q -2 -v 5 -T trunk.tsv -w -2 -U 2> stderr-stream0.2

and then the stderr-stream0.2 file shows:

So the error disappears but I still get no audio.

Your rx.py command line is a mess! For one, you're trying to direct audio to both the "Wireshark" (UDP) port (-w ) while expecting to receive audio from the Linux sound device using the (-U) command line argument. It has to be one or the other. You'll also need to include the
(-V) option to enable the Phase-1 vocoder. Also, don't arbitrarily add the (-x2) option as this will boost decoded audio levels that may well
introduce unwanted distortion.

Stick to the basics first and get it working! Then go back and fine tune options/settings as necessary. Begin testing using the following
rx.py command line shown below.

./rx.py --args 'rtl' -N 'LNA:47' -S 1000000 -f 770.19375e6 -o 25000 -q -2 -T trunk.tsv -U -V -2 -v 5 2> stderr-stream0.2

Are control and voice channel timeouts something to be concerned about? Still no audio.
From the README file:

It is still necessary to specify the "-w" (wireshark) option if using
either the internal or external audio server.

 

[VA4JOE]

By the way GQRX works good with audio.

 

[VA4JOE]

The README file also states:

NOTE 1: For phase1 voice the "-V" option is not used. Instead the
"-w" option is used (see AUDIO SERVER section, below). For P25 phase 2/TDMA audio decode,
the "-2" option is required in addition to the "-w" option.

And I thought since the P25 system I am trying to decode is said to be Phase 1 I should omit "-V".

 

[wgbecks]

You're getting some control channel decode but it doesn't appear there's any voice channel decode that explains why no audio.
In order to analyze what's wrong, the logging verbose needs to be increased to -v 10 that will write detailed information into the
logfile when executing op25. Increase logging verbose, restart op25 and allow it to run for a couple of minutes then capture and
post the new logfile.

Additionally, it will be very helpful to post your trunk.tsv file along with screen captures of the FFT, Constellation, and Mixer plots
taken while op25 is operating as a means to analyze signal quality and tuning accuracy that are equally important in achieving
reliable decodes of both the control and voice trunk channels.

Submit the following from the command line and post the output responses.

OK, looking like you're getting pretty good control channel decoding but not enough log capture to indicate what happens when
a talk group goes active. The FFT plot was the first of the three plots posted. Signal levels are quite strong but I am seeing what
looks like interference or signal artifacts on the high side of the mixer plot that needs to be investigated.

I recommend reducing LNA gain downward to approximately 35 to determine if this will reduce or eliminate the potential signal artifacts
that appear in the mixer plot. The offset isn't normally a requirement except to move the spike that commonly occurs with RTL devices
that can interfere with weaker signals. Offset can also be used to some extent to help fine tune the SDR to frequency but does require
cut and try methodology. Reduce the LNA to 35 and make the Offset 2500 instead of 25000 per the following.

./rx.py --args 'rtl' -N 'LNA:35' -S 1000000 -o 2500 -q -2 -T trunk.tsv -U -V -2 -v 10 2> stderr-stream0.2

Now, with these few changes, restart op25. Open another terminal session to view the logfile (tail -f stderr-stream0.2) as it's being
written. Let op25 to continue to run until there is sign of active talk group activity, then capture and post that data if there is still no
audio. The logfile text would look something like the following when decoding an FDMA (Phase-1) talk group,

Make a new set of plots and post that include FFT (1), Constellation (2), Datascope (4), and Raw Mixer (5) and include a screen capture
of the op25 terminal window while running that will indicate the frequency the SDR is tuned to and its approximate frequency error.

 

[wgbecks]

As a follow up. I would concentrate efforts on correcting the frequency error that's visible in the "Raw Mixer" plot that
indicates the center of the tuned IF spectrum is sitting low in frequency.

Earlier, I suggested lowering the offset to -o 2500 but I think to begin with you should remove it completely and then incrementally
adjust the PPM (-q -2) as needed to center the IF spectrum on the zero-center line of the raw mixer plot display per the example
shown below.

I'm not getting anything like what you posted about it decoding in the stderr-stream0.2 file.

It won't let me post the whole filee cause it's too long it says.

Still a little off frequency but not enough that you should not be getting audio on active talk groups. I am willing to look at your logfile
if you want to PM me to exchange contact (email) info. Let op25 run at logging verbose -v 10 for at least an hour then grab that file and
email it to me after we exchange email addresses.

A little off topic but I was messing around with GQRX and DSD and for the second voice frequency I was able to get some data. It seems like there is a mix of C4FM and GFSK traffic on that channel

Output to output.wav file.
I was able to get about a second of garbled audio in the wav file.

To the OP: Is this a phase 1 only (FDMA) system or does it carry phase 2 (TDMA) traffic too? I don't see any p25p2 log message or slotid in your log fragment so I'm thinking it might be a c4fm phase 1 system. In that case you'd probably want to add "-D fsk4" to the rx.py command line to force the demodulation which should correct the voice channel timeouts. Try it and see if it helps; if it's no better back the change out and post a longer log fragment at "-v 11" detail level containing some "voice update:" messages.

According to radioreference.com it is a P25 Phase 1 system with no phase 2 capabilities yet.

Gents,

I spun up a Debian Bookworm (v12) VM this afternoon and was able to build and run op25 successfully with no audio decode or
voice timeout issues. The only thing that gave me fits was that the apt repository installs Liquidsoap v2.1.3 that has changed the
scripting needed to make use of the output.icecast operator.

The most recent logs show the channel grants/updates being processed and a tuning command issues but no subsequent acquisition of framing on the voice channel.

It'd be interesting to observe the fft, mixer and datascope plots as tuning takes place to see if there really is a voice signal appearing at the expected location. With the current implementation of my demodulator, even if the ppm and/or tuning is off by 1-2khz it usually locks in eventually.

Am in the process of reinstalling op25 now....will update further...

 

[VA4JOE]

Ok so I made the mistake of running the install script as root because my user was not set up for sudo.

I have reinstalled op25. Now I get all zeros in the frequency part of the screen and can't seem to get a proper -q value to change that.
The frequency at the bottom is all wrong too.
