Re: [op25-dev] Info (need help) OP25 setup

Bare with a old Man( I'm anxious to get this working) I downloaded Ubuntu 14.04, never used Linux before I installed it along side windows 7, I used this method, pasted below to install OP25 Everything looks like it installed correctly, happy first timer no errors I went into files, all seems to be there I have a RTL2832u device The local system I want to track is Phase 2 , Tdma, I believe control channel 858.43750 How do I launch the program, scope.py is that correct I googled it, I found some things to try, 2 lines in command, no dice Is there a step by step anywhere, I can read. I've read and read, I know its just me but I'm closer than I was 4 days ago ?s (1)Do I launch by command prompt, is there an app to click on(2) how do I put in put my control channel, in my files somewhere) just some basic questions for a newbie thanks for any help . This recipe has been tested on ubuntu 14.04 only, it is likely NOT to work in either 12.04 or 16.04... First, use these commands to install the pre-reqs sudo apt-get update sudo apt-get build-dep gnuradio sudo apt-get install gnuradio gnuradio-dev gr-osmosdr librtlsdr-dev libuhd-dev libhackrf-dev libitpp-dev libpcap-dev git Second, use these commands to build and install OP25: [Note, the mkdir build; cd build; cmake ../; make; sudo make install sequence is a bog-standard form when source-building apps that utilize cmake.] cd ~ git clone git://op25.osmocom.org/op25.git cd op25 mkdir build cd build cmake ../ make sudo make install sudo ldconfig Finally you may need to use the command sudo rmmod dvb_usb_rtl28xxu to remove the DVB kernel module that conflicts with the RTL USB SDR. You may also need to edit the system udev rules for the RTL -both are common issues and you can search for the needed resources if the RTL isn't getting recognized... Once this is all done (no longer a need to source any env commands into the shell) you should be ready to invoke scope.py, which is the principal OP25 GUI app... As a pre-check, you can also run the osmocom_fft application (which should install as part of the pre-reqs) to test basic RTL connectivity and rule out related problems before invoking scope.py...
