I know that a while back there was a grc flowraph of op25 that handled DES. Any chance of a pybombs recipe for op25 that handles RC4 as implemented in Advanced Digital Privacy?

balint256 op25 repo is several commits behind the osmocom.org op25 repo

by ikj1234i＠yahoo.com [op25-dev]

Greetings It looks like the balint256 'op25' repo tracks the op25 repo at op25.osmocom.org only up to commit 2051a96198c. The op25.osmocom.org repo has more than a dozen additional commits beyond that, which means that the balint256 op25 install is approx. one year out of date. All of balint's changes don't affect the op25_repeater, so there shouldn't be a big hassle when the time comes to merge everything into master. It looks only like one or two CMakeLists.txt files might have merge conflicts, YMMV. Accordingly, I recommend as follows (until such time as the merge may happen) - use only the op25.osmocom.org build when running scope.py - use only the balint256 one with balint's associated changes - keep them otherwise separate Max ps. Knuckle Punch to Balint!!

p25_frame_assembler performance problems

by lukekb＠gmail.com [op25-dev]

I am trying to record a Phase 1 P25 Trunking systems. I have a bunch of OP25 records hooked up to the different channels that the system could use. I have a Valve in the flow graph that will allow samples to pass or dump them to a null_sink. This lets me turn P25 recorders on or off. The problem is that the recorders using OP25 seem to using a ton of CPU even if they are not getting samples. I tracked it down to the p25_frame_assembler block. Whenever it is connected to a flow graph, it seems to be using a lot of CPU, even if it is not getting any samples. Any ideas why the p25_frame_assembler block would be using CPU cycles even if it is not getting samples in? I am running it with the following params: bool do_imbe = 1; bool do_output = 1; bool do_msgq = 0; bool do_audio_output = 1; bool do_tdma = 0;

waterfall

by Sean Kealy superstardodge＠yahoo.com [op25-dev]

Ok I know I asked this before but im still stuck, why when I launch op25_25.PY I just get the waterfall app, im using the black rtl sdr how do I tell it to tune o a frequency? Where could I find the op25.grc file and just run op25 in gnu radio companion? Yea I know, I suck, I ask alot of dumb questions , but im tryin! Cant wait for the live cd to come out!

scope.py 'CreateStatusBar' error on OSx

by el3ctr0magn3tic＠yahoo.com [op25-dev]

Hi all, New to the group here, been looking all over for similar issues to one I'm having, but to no avail. There was one mention of this exact error on the radioreference op25 "main" thread, but it seems it was left unsolved or forgotten. From detailed digging I've done, think it may be related to wxgui-3.0 vs 2.8? Or should I be running this with Gnuradio 3.6 instead? Greatly appreciate any assistance! The following is my baseline: OSx 10.10.4 Gnuradio 3.7.8.1 (installed via Macports) gr-op25 (Balint's git most recent version) - made some minor changes to cmake to find macports GR and libs gr-op25 seems to compile and build fine, however when running scope.py I get the following error, and the app never loads: $ python2.7 ./scope.py --args “hackrf” -f 502.9125e6 -S 8000000 -T trunk.tsv -2 Mac OS; Clang version 7.0.0 (clang-700.0.72); Boost_105900; UHD_003.009.001-MacPorts-Release gr-osmosdr v0.1.x-xxx-xunknown (0.1.5git) gnuradio 3.7.8.1 built-in source types: file fcd rtl rtl_tcp uhd hackrf bladerf rfspace airspy Using HackRF One with firmware git-44df9d1 gain: name: RF range: start 0 stop 14 step 14 gain: name: IF range: start 0 stop 40 step 8 gain: name: BB range: start 0 stop 62 step 2 supported sample rates 8000000-20000000 step 2000000 Traceback (most recent call last): File "./scope.py", line 2817, in <module> app = stdgui2.stdapp(p25_rx_block, "APCO P25 Receiver", 3) File "/opt/local/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/site-packages/gnuradio/wxgui/stdgui2.py", line 46, in __init__ wx.App.__init__ (self, redirect=False) File "/opt/local/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/site-packages/wx-3.0-osx_cocoa/wx/_core.py", line 8628, in __init__ self._BootstrapApp() File "/opt/local/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/site-packages/wx-3.0-osx_cocoa/wx/_core.py", line 8196, in _BootstrapApp return _core_.PyApp__BootstrapApp(*args, **kwargs) File "/opt/local/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/site-packages/gnuradio/wxgui/stdgui2.py", line 49, in OnInit frame = stdframe (self.top_block_maker, self.title, self._nstatus) File "/opt/local/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/site-packages/gnuradio/wxgui/stdgui2.py", line 76, in __init__ self.panel = stdpanel (self, self, top_block_maker) File "/opt/local/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/site-packages/gnuradio/wxgui/stdgui2.py", line 98, in __init__ self.top_block = top_block_maker (frame, self, vbox, sys.argv) File "./scope.py", line 201, in __init__ self.__init_gui(frame, panel, vbox) File "./scope.py", line 537, in __init_gui self.frame.CreateStatusBar() File "/opt/local/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/site-packages/wx-3.0-osx_cocoa/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
