Thank you. Will OP25 work with 2 Airspys, or do they have to be RTL-SDR dongles?

If you are not familiar with Linux, I'd suggest the LTS (Long Term Support) release. Once you've got Ubuntu installed, you can use

git clone https://github.com/boatbod/op25.git

to get a copy of boatbod's version of op25. Once that finishes downloading,

cd op25 ../install.sh

should get you a working install of the software. Beyond that, there are a lot more people that can help in the RadioReference forums than there are here so I'd suggest visiting

https://forums.radioreference.com/software-defined-radio/

That's one way. You can also use the package manager. Sent from my Verizon, Samsung Galaxy smartphone -------- Original message --------From: "'Trunk Tracker' trunktracker@tampabay.rr.com [op25-dev]" op25-dev@yahoogroups.com Date: 11/24/18 5:00 PM (GMT-05:00) To: op25-dev@yahoogroups.com Subject: RE: {Disarmed} [op25-dev] Beginner's Guide To Setting Up OP25 From Scratch

Thanks. I went ahead and installed the LTS version into VMWare and the install seemed to go fine with no problems.  I am new to Linux, so this will be a gradual process.  When I run the command "git clone https://github.com/boatbod/op25.git", I get an error in the terminal that says: "Command 'git' not found, but can be installed with: sudo apt install git" So am I supposed to run the command "sudo apt install git" first before I can install OP25?  So I guess with Linux, to install something off the internet, you type a command line instead of going to a website and downloading the files? trunktracker@tampabay.rr.com From: op25-dev@yahoogroups.com [mailto:op25-dev@yahoogroups.com] Sent: Friday, November 23, 2018 10:41 PMTo: op25-dev@yahoogroups.comSubject: Re: {Disarmed} [op25-dev] Beginner's Guide To Setting Up OP25 From Scratch   If you are not familiar with Linux, I'd suggest the LTS (Long TermSupport) release.

Does "lsusb" see your AirSpy device? You have lots of errors in your output but the

FATAL: Failed to open AirSpy device (-5) AIRSPY_ERROR_NOT_FOUND

seems like the first one to solve and it may solve the rest. You're doing this under VMWare, correct? Is VMWare making the USB device available to your virtual machine?

Trunktracker

Here are a couple of steps to insure that your Airspy device is available to your Ubuntu VM.

* Remove one of the Airspy devices. You do not need two devices in rx.py. * Set /verify that the remaining Airspy device is virtualized in your VMware settings menu for the Ubuntu VM. * Start the Ubuntu VM then execute lsusb from the command line. It should return somethings like the lines below if your Airspy devices has been virtualized.

Yes, you're right. It's Hillsborough County, FL:

https://www.radioreference.com/apps/db/?sid=7236

Thanks for the help. I have double-checked the control channel and it actually is on 769.28125 (with a nice strong signal) which is listed as an alternate control channel on the west site.

So If I run this command:

../rx.py --args 'airspy' -S 3000000 -N 'LNA:15,MIX:15,IF:15' -f 769.28125e6 -t -q 0 -V -U 2> stderr.2

here is what I get:

The program never really runs anything and just stops after saying it set those 3 gain settings.

But if I change it to say 'airspymini' instead of just ' airspymini', then I get this screen again:

This is a very slow system with little activity on it. So maybe I just to wait for a transmission?

For the command line options, the readme file doesn't seem to give you examples or lists of values of what to actually type. For example, the -N 'LNA:15,MIX:15,IF:15' syntax was something I searched for and found in a RadioReference forum. One of my screenshots below shows "built-in source types:" with what looks like a list of things that can be entered with the --args command. But it doesn't list 'airspymini' as one of the options and I wonder if it should?

And how about this question. How come we use an "e6" after the frequency -f 769.28125e6?

OK. You’re making good progress. The last screen capture below is blank so I can’t see what it flipped to.

I appears that you are attempting to decode Hillsborough County (P25) but may not have specified the correct control channel frequency according to

the listing for Hillsborough County on radioreference.com. You might need to try 770.33125 or 769.80625 instead of 769.28125.

The following rx.py command line will work without a trunk.tsv file and will decode the system provided you specify the correct (active) control channel.

../rx.py --args 'airspy' -S 3000000 -N 'LNA:15,MIX:15,IF:15' -f 769.28125e6 -t -q 0 -V -U 2> stderr.2

The 2> stderr.2 will send error messages and other status to a logfile and will prevent garbage from appearing on your terminal screen.

This same logfile will also be very helpful if things still don’t work to diagnose the problem.

When you have the correct control channel frequency, your terminal screen should look something like my screen

capture shown below except that it will display your systems NAC, WACN, SYSID, and frequency.

When op25 is working the tsbks (Trunk Signaling Blocks) value will constantly increment except when

voice traffic is present, and will then resume as soon as the system goes idle again. Other data will

be displayed indicating the voice trunk frequency and talkgroup ID when there is traffic present.

Trunktracker,

From what I can fine the Airspy Mini gets configured the same as the Airspy R2 with

the exception being the sample rate differences.

I further assume from an earlier posting that your installed the op25/boatbod version that

supports starting rx.py without a trunk.tsv file using just the -t option. This was a handy

feature that allows you to discover the P25 system’s NAC, SID, and other information needed to properly

construct your trunk.tsv file.

As has already been suggested, do post your stderr.2 logfile. OP25 will create and write to the logfile

(stderr.2) each time you execute the rx.py command line with the 2> stderr..2 option specified. The

Information contained in that logfile should prove useful to diagnose what is happening.

Bill, WA8WG

Right .. so (I think) you still need to resolve this AIRSPY_ERROR_NOT_FOUND issue. When you use "airspymini" (bogus), it doesn't even try to find your AirSpy device.

I don't have any AirSpy hardware, so can't test anything, but Googling for that error found:

https://github.com/airspy/airspyone_host/issues/40

I'd start there...

Hi all,

I was able to replicate the identical issue as trunktracker has reported. It turns out to be a hardware virtualization issue in handling of the Airspy SDR's running on Ubuntu as a VM on VMWare Player and not an issue with the op25 code.

Normally, I use Oracle VirtualBox on a Windows-10 Pro 64 machine to run various Linux VM's including Ubuntu 18.04 with op25. That combination has worked perfectly using either the Airspy R2 or the RTL SDR's. However, I installed VMWare Player 15 last evening to experiment with Ubuntu 18.04 VM and boatbod op25 to quickly discover I got the same results (error message) as trunktracker when attempting to run my Airspy R2. Conversely, op25 did run perfectly on the VMWare Player setup as long as I only used the RTL SDR device.

So it then appears to be some type of virtualization issue with the Airspy devices on VM's running on the VMWare Player. I don't know that is necessarily the case on other VMWare products such as the Pro version, and etc. But it's definitely broken as far as the Airspy is concerned with VMWare Player. Changing USB modes (support) in the VM settings had not impact on the problem either.

I ran into a similar problem recently on my Windows-10 Machine where none of my SDR's, Airspy or RTL types would run on any of my Linux VM's. That turned out to be a issue with Windows Defender causing a corruption with the USB hardware virtualization in VirtualBox.

It looks like gr-osmosdr now has the work around removed (since July 2017) - https://github.com/osmocom/gr-osmosdr/commit/ea6b356cfda8a90fa6d727fcc13aae6 0547962a2

All,

I was able to successfully get the Airspy R2 to run in op25 on an Ubuntu 18..04 VM on VMWare Workstation Player-15 using the work around procedure pointed out in

~iain posts.

On my machine the Airspy device was found as follows;

I125: USB: Found device [name:OpenMoko\ AIRSPY vid:1d50 pid:60a1 path:1/0/0 speed:high family:vendor instanceId:USB\VID_0E0F&PID_0001\AIRSPY_SN:03A464C8373E4F67 serialnum:AIRSPY_SN:03A464C8373E4F67 arbRuntimeKey:4 version:3]

I then added the following line to my VMWare Virtual Machine Configuration file to complete the work around procedure.

usb.quirks.device0 = "0x1d50:0x60a1 skip-reset, skip-refresh, skip-setconfig"

Trunktracker,

You now have reference to a fix that works and has been tested with VMWare Workstation Player, else you can move to Oracle VirtualBox and build your Ubuntu VM on that platform.

Here is a screen capture of op25 with my Airspy R2 running on the VMWare Workstation Player VM.

Bill, WA8WG

So now I'm looking at all this and don't know where this " VMWare Virtual Machine Configuration file" is. Where do we find this file? And the thread shows a command of:

usb.quirks.device0 = "0x1d50:0x60a1 skip-setconfig"

but you actually used

usb.quirks.device0 = "0x1d50:0x60a1 skip-reset, skip-refresh, skip-setconfig"

instead?

Great - you're making progress!

op25 uses ALSA to play the audio. In a Terminal window, type "aplay /usr/share/sounds/alsa/Front_Center.wav". Do you hear anything? If not, you might need to run "alsamixer" and unmute your playback device, or/and adjust the level.

You’re not going to get any audio from the speakers with the -w option specified as this is telling op25 to output udp packets. Drop the -w and replace with -V per the following.

Ah yes. I am not sure that you can get audio with the -t specified instead of using -T trunk.tsv on the rx.py command line. The intent of having him use -t for initial startup was to determine the NAC of his system ,and to eliminate any possibilities incorrect formatting of the trunk.tsv file from preventing op25 from running. Time now to add trunk.tsv to the mix now that op25 will start up and run.

I have both -w -and -U in mine, and it outputs audio. -w is probably not necessary, but I don't think it hurts anything.

Not sure about -t - it's labeled "use experimental tone detect algorithm" - I'm not using that.

Hi all,

I was able to replicate the identical issue as trunktracker has reported. It turns out to be a hardware virtualization issue in handling of the Airspy SDR’s running on Ubuntu as a VM on VMWare Player and not an issue with the op25 code.

Normally, I use Oracle VirtualBox on a Windows-10 Pro 64 machine to run various Linux VM’s including Ubuntu 18.04 with op25. That combination has worked perfectly using either the Airspy R2 or the RTL SDR’s. However, I installed VMWare Player 15 last evening to experiment with Ubuntu 18.04 VM and boatbod op25 to quickly discover I got the same results (error message) as trunktracker when attempting to run my Airspy R2. Conversely, op25 did run perfectly on the VMWare Player setup as long as I only used the RTL SDR device.

So it then appears to be some type of virtualization issue with the Airspy devices on VM’s running on the VMWare Player. I don’t know that is necessarily the case on other VMWare products such as the Pro version, and etc. But it’s definitely broken as far as the Airspy is concerned with VMWare Player. Changing USB modes (support) in the VM settings had not impact on the problem either.

I ran into a similar problem recently on my Windows-10 Machine where none of my SDR’s, Airspy or RTL types would run on any of my Linux VM’s. That turned out to be a issue with Windows Defender causing a corruption with the USB hardware virtualization in VirtualBox.

Your logfile reports that op25 does not see your Airspy device. This may be as a result of a virtualization problem with your Ubuntu VM. Run another lsusb and see if the Airspy device still

shows up or not. If it does, then I would be suspect that the airspy library did not initiate properly during the installation phase. BTW, you don’t need the -2 in your rx.py command line because your county is running a Phase-I system. Of course, that is not the issue at this point in time.

I am willing to help you over the phone if you want some help and want to install TeamViewer on your PC so that I can access your VM remotely to take a look at a few things.

Trunktracker,

From what I can fine the Airspy Mini gets configured the same as the Airspy R2 with

the exception being the sample rate differences.

I further assume from an earlier posting that your installed the op25/boatbod version that

supports starting rx.py without a trunk.tsv file using just the -t option. This was a handy

feature that allows you to discover the P25 system’s NAC, SID, and other information needed to properly

construct your trunk.tsv file.

As has already been suggested, do post your stderr.2 logfile.. OP25 will create and write to the logfile

(stderr.2) each time you execute the rx.py command line with the 2> stderr..2 option specified. The

Information contained in that logfile should prove useful to diagnose what is happening.

Bill, WA8WG

Thanks. I've gone ahead and built a file called HillsboroughWest.tsv for this system https://www.radioreference.com/apps/db/?sid=7236:

(I actually took one of the existing files that come with op25 and just edited it.) If I run the command line:

../rx.py --args 'airspy' -S 3000000 -N 'LNA:15,MIX:15,IF:15' -f 769.80625e6 -T HillsboroughWest.tsv -q 0 -2 -w -U 2> stderr.2

The program doesn't start up and I get this:

The stderr.2 file shows this:

If I try using one of the other files that come with OP25 like ontario.tsv or nyseg.tsv in the command line instead, it behaves the same way.

Trunktracker,

The terminal screen isn’t designed to dump a lot of technical information that you are probably used to with Unitrunker… However, you can get a great deal of technical information form op25 by

setting a verbose level whereby the diagnostic data dumps to the stderr.2 logfile for later review.

To tun on just a -v 5 to your rx.py command line. You can simply edit hills.sh and add this to the command line. The logging verbose level ranges form 1-10 with a tremendous about of data being dumped on level 10 that includes the P25 LDU1/LDU2 packets and a but more stuff.

Now here is yet another option. OP25 supports a GUI called the http console. Add the following to your rx.py command line or again to hills.sh. -l http:0.0.0.0:8080 Note that the normal console output will stop with the option and it will look like op25 is broke, it’s not. Just minimize the terminal window in Ubuntu and open up Firefox. Type in http://127..0.0.1:8080 and you’ll be connected to the http console in op25. You’ll like what you see there including the ability to hold an active talkgroup.

You can also utilize the whitelist or blacklist features in (trunk.tsv) hills.tsv to either allow specific talkgroups to block specific talkgroups. Start with the http console first and then we can work on the whitelists / blacklists. BTW, one of the files I sent you, hills-tgids.tsv gets called by hills.tsv and provides alpha tags and some other info relevant to Hillsborough County that I pulled off of

radioreference.com and ran through a tool that I built to crate tag files.

If you haven’t edited a file yet in Linux, use one of the build in editors. the nano editor is very easy to use. Google it for basic use examples. Lastly, you are more than welcome to give me

a call and I can walk you through a few steps to automate some of these processes and to discuss features and options. My phone number was contained in the email sent last Friday but if you don’t have it then PM me and I will provide it to you again.

Oh, you can open the http console from any browser on your LAN as long as you know the IP address Ubuntu is running on. It’s best to assign a static LAN IP to Ubuntu for a host of reasons including

have a known address to access the http console and/or to open an ssh session to Linux.

Bill

Thanks very much. I do like to keep anonymous online where possible, but this is all a big help. If I type "chmod +x hills.sh", the terminal window basically does nothing and acts like I just pressed enter. But when I run ../hills.sh, it works.

This is totally cooltacular. Really enjoying it. The audio quality is much more stable and steady than other ways of monitoring. But it's also very quiet volume even though I've got all the volume settings all the way up.

The stock/default trunk..tsv file that comes with OP25 has multiple different systems in it. So how do you tell it what system you wanna listen to? And is there a way to tell it a talk group ID you want to hold on without having to wait until it stops on that ID, if it ever does?

There doesn't seem to be much of a system activity display like Unitrunker. I found from an online thread that to adjust the scan / search delay setting, in the file trunking.py find the following line and change it from 2 seconds to something else:

self.TGID_HOLD_TIME = 2.0 # TODO: make more configurable

BTW, one of the files I sent you, hills-tgids.tsv gets called by hills.tsv and provides alpha tags and some other info relevant to Hillsborough County that I pulled off of

radioreference.com and ran through a tool that I built to crate tag files.

If you haven’t edited a file yet in Linux, use one of the build in editors. the nano editor is very easy to use. Google it for basic use examples. Lastly, you are more than welcome to give me

a call and I can walk you through a few steps to automate some of these processes and to discuss features and options. My phone number was contained in the email sent last Friday but if you don’t have it then PM me and I will provide it to you again.

Oh, you can open the http console from any browser on your LAN as long as you know the IP address Ubuntu is running on. It’s best to assign a static LAN IP to Ubuntu for a host of reasons including

have a known address to access the http console and/or to open an ssh session to Linux.

Thanks very much. I do like to keep anonymous online where possible, but this is all a big help.. If I type "chmod +x hills.sh", the terminal window basically does nothing and acts like I just pressed enter. But when I run ./hills.sh, it works.

This is totally cooltacular. Really enjoying it. The audio quality is much more stable and steady than other ways of monitoring. But it's also very quiet volume even though I've got all the volume settings all the way up.

The stock/default trunk..tsv file that comes with OP25 has multiple different systems in it. So how do you tell it what system you wanna listen to? And is there a way to tell it a talk group ID you want to hold on without having to wait until it stops on that ID, if it ever does?

There doesn't seem to be much of a system activity display like Unitrunker. I found from an online thread that to adjust the scan / search delay setting, in the file trunking.py find the following line and change it from 2 seconds to something else:

self.TGID_HOLD_TIME = 2.0 # TODO: make more configurable
