Hi Folks, new here.. Did a lot of looking around, but didnt see the answer to this. I want to use app_rpt as my repeater controler and support P25 + NBFM. I see a rx-to-asterisk app here, but not a corresponding asterisk-to-tx app. I saw a repeater app but didnt appear to support asterisk. Am I missing something or does it not exist? Thanks!

Exception running OP25

by md123＠nycap.rr.com

I am using using ubuntu 12.10 i am trying to run OP25 (python version 2.7.3), in GNU Radio Companion v3.6.3-35-g4435082f and i get an error. So I run the traceback command in terminal: ~$ python -m trace --count -C . op25_grc.py Here is the output with an error: Imported legacy fsk4 Using Volk machine: ssse3_32 Traceback (most recent call last): File "/usr/lib/python2.7/runpy.py", line 162, in run_module_as_main "_main__", fname, loader, pkg_name) File "/usr/lib/python2.7/runpy.py", line 72, in run_code exec code in run_globals File "/usr/lib/python2.7/trace.py", line 819, in main() File "/usr/lib/python2.7/trace.py", line 807, in main t.runctx(code, globs, globs) File "/usr/lib/python2.7/trace.py", line 513, in runctx exec cmd in globals, locals File "op25_grc.py", line 493, in tb = op25_grc() File "op25_grc.py", line 231, in __init_ self.wxgui_fftsink2_0_0.set_callback(wxgui_fftsink2_0_0_callback) File "/usr/local/lib/python2.7/dist-packages/gnuradio/gr/hier_block2.py", line 54, in getattr return getattr(self._hb, name) AttributeError: 'gr_hier_block2_sptr' object has no attribute 'set_callback' I really really want to get OP25 running but have not been able to figure out what is the solution to this error (AttributeError: 'gr_hier_block2_sptr' object has no attribute 'set_callback') . it'll take me ages to figure out how to debug in python. some threads have said its because gnuradio is an older version but in my case it is not. i am wondering if the question is too amateur or something because nobody is lending assistance. Any help will be so very much appreciated. Thanks.

Runtime error- ioctl(d_tap, TUNSETIFF, &ifr): Operation not permitted

by md123＠nycap.rr.com

Has anyone seen this error? i cant find anything on the web about this. I already had to disable the Waterfall sink and the FFT sink in order to get rid of the "AttributeError: 'gr_hier_block2_sptr' object has no attribute 'set_callback'" error. Now OP25 dies this way: Imported legacy fsk4 Using Volk machine: ssse3_32 RTL2832 Source block configuration: Read length (bytes): 262144 Buffer enabled: yes Buffer multiplier: 8 Buffer size (samples): 1048576 Samples per read: 131072 Buffer level: 50.0% Successfully initialised demod: "ezcap EzTV" Probing "e4k"...not found.

I installed GNUradio using the build script on Balint's "how to build page" but OP25 I had to build from source because the build script there has a broken link. Any help will be much appreciated.

Jumping in

by contrapezist

Hello all, They accepted my request for membership (what were they thinking). So Im just going to jump right in and see what if anything I can contribute and try to not ask too many silly questions. Altho P25 isnt my main area of interest it is something to work with as there is a P25 system locally with a combination of clear and ADP encrypted traffic on it. Being the nosey type I am like to see whats going on with the system. As for myself an electrical engineer currently working in broadcast television. Not much of a programmer have done a bit of c for microchip pic in recent years and linux is something I havnt played with in 15 or more years so a bit rusty. I do speak fluent cisco and have a way of scavenging nice hardware. The corprate IT dept is in our building and its a revolving door they give about 4 years at the outside before turning down a system. Currently sitting on an IBM x455 cluster that really needs something to do other than track satellites :) Trying to latch on to the blade centers but they still have signifigant value and are easy to ship. Thats me in a nut house I mean nut shell reading thru the threads and site trying to get something workable to start and take it from there. Austin

OP25 and WireShark Help

by rbrtklamp

Has anybody had any luck getting OP25 to work. I have been going crazy trying to get this program installed and running but it always gives me errors. I have tried ubuntu 9.10 but they no longer release or update any packages for that version anymore. So now I am on to Ubuntu 10.04 GNUradio installs fine but I get a ton of errors when trying to install OP25. My end game is to be able to use OP25 with wire shark to review the data packets. Right now I am at a loss, I am not very Linux literate and really have a almost no knowledge on how the operating system works. I should add I installed and use DSD just fine, thats why this op25 thing is driving me crazy I follow every part of the building instructions to the T and still get errors and missing pieces. I am at the point that I am willing to pay somebody for their time if someone would be kind enough to contact me directly I will give you my phone number and we can go from there. Just let me know what I owe you for your time and I will paypal it over to you. Bottom line is I NEED to get this program up and running with wire shark for a project me and some Friends are working on. Any help would be very much appreciated and I am more than happy to compensate any for their time if somebodies willing to walk me through the set-up and figure out why I cant get it running. PLEASE HELP! Any one interested can contact me here directly at the email address below. Thank you all for your time, Robert Klamp RobertKlamp at Comcast dot net

trouble running OP25

by md123＠nycap.rr.com

Hi guys. I was able to successfully compile and install (at least with no errors) OP25, gr-fsk4, wireshark, and GNUradio. Using Ubuntu 12.10 and all of the latest for the OP25, gr-fsk4, wireshark, and GNUradio. Now I am confused here because OP25, fsk4 decoder, and wireshark, are not found in my GNUradio. Anyone have any ideas of why GNUradio doesnt have available the blocks i installed? Any help is much appreciated, Thanks a bunch, Matt

P25 Transmission

by rosin.f＠att.net

Hello brains, Qt the boto; of this page: http://op25.osmocom.org/wiki/wiki/RepeaterPage I would like to understand the limitation of the USRP transmission: - Why is the channel spacing arbitrarily 25 kHz (just a SW limitation ?) - Are you transmitting the P25 air interface for voice ? Thank you,
