Haven't done a lot of testing, but it should now be possible to install gr-op25 (and all of its prerequisites, including gnuradio) simply by - cloning the pybombs repo - cd to the toplevel ---- cd pybombs - ./pybombs install gr-op25
Assuming no bugs, it should no longer be necessary to separately clone the gr-op25 repository, or to copy any recipes around... Also, the trunking changes have been merged into gr-op25 master, so the 'git checkout' commands shouldn't be necessary any more, either...
Once the process has been more thoroughly tested, I'll be updating the wiki with these procedures

I did a complete reinstalled of everything last night and the master branch had everything in it. I've attached an install log for your review.
I'm having RTL issues now, but it's not related to OP25 so I'll skip those comments.
There are problems with the op25_repeater blocks in GRC though. Adding fsk4_slicer_fb, p25_frame_assembler, and vocoder to the canvas produced the following error and crashes GRC:

Hope this is helpful..

I forgot to mention another error I encountered.. in the file /gr-op25/op25/gr-op25_repeater/grc/op25_repeater_fsk4_slicer_fb.xml
I changed this <make>op25_repeater.fsk4_slicer_fb($&slice_levels)</make> to <make>op25_repeater.fsk4_slicer_fb($slice_levels)</make>

Hi Scott
Thanks for the bug report. The amount of unfinished work is clearly excessive : )
Almost no GRC and XML work has been done so far, that I know of. Some of my early hacks may have ended up in git, and it sounds like these issues may be caused by that - I'll have to take a look. One of the problems is all of those blocks are fairly low level and we need to wrap a lot of that funcionality into GNU Radio hierarchical blocks written in python. These are typically set up as modulator / demodulator blocks which combine channel filtering, demodulation, slicing, etc. into unified functional blocks. The latter are the ones that should be exposed to GRC via XML....

Another bug to report... running the scope app with the -V option crahes

the above error message is the key. Debugging linux audio can sometimes be a pain, here is one place to start: http://gnuradio.org/doc/sphinx/audio/index.html
That page describes the audio sink block, the second parameter of which is the name of the audio device, which is set using the -O option of scope.py. If your system uses pulseaudio you can try '-O pulse' etc.
Another thing to try is to see if alsa is even installed: dpkg-query -l | grep -i alsa

Sorry for the erroneous report Max.. I clearly have unresolved issues with the gnuradio/pybombs install at this point. I'll try and read what the errors are telling me before doing that again, sorry bud!
