OP25 Install on Arch Linux Failing [1 Attachment]

by Mark Tomlin dygear＠gmail.com [op25-dev]

I ran the following commands a couple of minutes ago after installing the dependencies. (Except for DOXYGEN_EXECUTABLE, that you'll see me install.) It's failing with the following message under the *Scanning dependencies of target imbe_vocoder*. [ 54%] Building CXX object op25/gr-op25_repeater/lib/imbe_vocoder/CMakeFiles/imbe_vocoder.dir/pitch_est.cc.o /*home/dygear/op25/op25/gr-op25_repeater/lib/imbe_vocoder/pitch_est.cc:60:1: error:* narrowing conversion of ‘*32970*’ from ‘*int*’ to ‘*Word16 {aka short int}*’ inside { } [*-Wnarrowing*] *}*; *^* ...

Stay tuned?

by Apu apu＠spfld.com [op25-dev]

Any advice or hints on getting scope.py tuned and then to stay tuned? (I'm trying to listen to New Jersey Interoperability Communications System -- P25 Phase II -- in case it matters.) When I first played with op25 a few months ago, I stuck it on a spare computer with a NooElec SDR dongle. Took a little futzing but I had it up and running in a day or so and it actually stayed working perfectly for close to 6 weeks. But this was just a test so that computer wasn't on a UPS and shut down during a power failure. Same hardware and I haven't been able to get it to stay tuned for more than a few hours since. Figured maybe it was just the SDR dongle drifting so I bought a RTL-SDR dongle which is supposed to drift less but I'm still having problems getting the system to tune for more than 30 minutes or so. Your thoughts are appreciated. Thanks, -- Apu <apu(a)spfld.com>

Unable to Run scope.py

by Brett Friermood brett.friermood＠gmail.com [op25-dev]

BretJust built OP25 on Debian Jessie without issue. However when I try to run a simple scope command it fails with the following error: Traceback (most recent call last): File "./scope.py", line 2751, in <module> app = stdgui2.stdapp(p25_rx_block, "APCO P25 Receiver", 3) File "/usr/lib/python2.7/dist-packages/gnuradio/wxgui/stdgui2.py", line 46, in __init__ wx.App.__init__ (self, redirect=False) File "/usr/lib/python2.7/dist-packages/wx-3.0-gtk2/wx/_core.py", line 8628, in __init__ self._BootstrapApp() File "/usr/lib/python2.7/dist-packages/wx-3.0-gtk2/wx/_core.py", line 8196, in _BootstrapApp return _core_.PyApp__BootstrapApp(*args, **kwargs) File "/usr/lib/python2.7/dist-packages/gnuradio/wxgui/stdgui2.py", line 49, in OnInit frame = stdframe (self.top_block_maker, self.title, self._nstatus) File "/usr/lib/python2.7/dist-packages/gnuradio/wxgui/stdgui2.py", line 76, in __init__ self.panel = stdpanel (self, self, top_block_maker) File "/usr/lib/python2.7/dist-packages/gnuradio/wxgui/stdgui2.py", line 98, in __init__ self.top_block = top_block_maker (frame, self, vbox, sys.argv) File "./scope.py", line 212, in __init__ self.__init_gui(frame, panel, vbox) File "./scope.py", line 466, in __init_gui self.frame.CreateStatusBar() File "/usr/lib/python2.7/dist-packages/wx-3.0-gtk2/wx/_windows.py", line 615, in CreateStatusBar return _windows_.Frame_CreateStatusBar(*args, **kwargs) wx._core.PyAssertionError: C++ assertion "!m_frameStatusBar" failed at ../src/common/framecmn.cpp(381) in CreateStatusBar(): recreating status bar in wxFrame The command I am running is simply "./scope.py -f 152.5925e6". Other references to this error that I have been able to find appeared to all be resolved by adding or properly formatting the NAC in the trunk.tsv file. Scope.py properly finds the SDR dongle, and will set the gain if I provide the argument, but always fails with this error and never opens the GUI. I'm sure I'm missing something simple. Thanks, Brett

Migration of op25.osmocom.org ?

by Harald Welte laforge＠gnumonks.org [op25-dev]

Dear all, the op25.osmocom.org site is currently a lxc (linxu container) setup on one of my servers, and it frequently locks up the entire container every so often, without any reason why. I have failed to find the root cause of this and given up by now. As all of the other osmocom projects have meanwhile migrated away from trac to the redmine based setup at http://projects.osmocom.org/, I would stongly suggest the OP25 project to migrate there, too. This would include: * migration of the wiki pages (Holger has some semi-automatic process for that which imports the content but still requires manual fix-up of a lot of formatting) * migration of the tickets (Holger also did that programmatically for the other projects) * import of the SVN repository to our git server (see http://git.osmocom.org) Is there a way we can encourage the current active OP25 community to go ahead with the above migration? In the end, the closer you align in terms of infrastructure with the other osmocom.org projects, the more likely it is that the content will be available, systems and software updated, content backed up, etc. I think in the end, it would be better for everyone - including me for being responsible that the site is currently down very often.

APCO P25 Decoding error (aUaUaU...) [5 Attachments]

by pindrop82＠yahoo.com [op25-dev]

Greetings, Was able to install (Ubuntu 14.04) and have a working APCO P25 receiver, but when i run scope.py to decode the primary CC i am getting aUaUaU....error (see attached terminal error). It only works partially (audio interrupted or broken) when i omit the secondary CC (866.0750) from the trunk.tsv file. The problem may be the secondary control channel in the trunk.tsv file. When I add the secondary CC on the trunk.tsv it does not go to primary channel. P25 receiver attempts to decode on the alternate CC. Have not been able to fix that issue. I am using the same NAC for both CC! Command Line: ./scope.py --args 'rtl=0' -N 'LNA:40' -S 960000 -f 868.06250 -o 20000 -q 44 -v 0 -V -T trunk.tsv Attached trunk.tsv, talkgroups.tsv, terminal error, traffic screenshot and constellation screenhot. Any help would be appreciated. Best Regards, TJ
