Here is the last screenshot that didn't go through before: 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? trunktracker@tampabay.rr.com From: wllmbecks@gmail.com [mailto:wllmbecks@gmail.com] Sent: Sunday, November 25, 2018 10:28 PM To: op25-dev@yahoogroups.com Cc: trunktracker@tampabay.rr.com Subject: FW: [op25-dev] Re: Beginner's Guide To Setting Up OP25 From Scratch 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... ~iain

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.

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.

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.

"not an issue with the op25 code." There's hasn't been a single issue in this entire thread that is an OP25 problem... On Fri, 30 Nov 2018 at 10:13, wllmbecks@gmail.com [op25-dev] < op25-dev@yahoogroups.com> wrote:

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.

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.)

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 trunktracker@tampabay.rr.com <mailto:trunktracker@tampabay.rr.com> From: op25-dev@yahoogroups.com <mailto:op25-dev@yahoogroups.com> [mailto:op25-dev@yahoogroups.com] Sent: Sunday, December 02, 2018 4:35 PM To: op25-dev@yahoogroups.com <mailto:op25-dev@yahoogroups.com> Subject: RE: {Disarmed} RE: [op25-dev] Re: Beginner's Guide To Setting Up OP25 From Scratch Correct.

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 trunktracker@tampabay.rr.com <mailto:trunktracker@tampabay.rr.com>
