Hi I am new to the group and GNUradio. I have installed gnuradio on ubuntu 12.04 from the directions at this link. http://blogs.bu.edu/mhirsch/2012/07/installing-gnu-radio-in-ubuntu-12-04-x6… I then went to the build instructions page and followed them to the T, all seemed to be going well but when I enter the command line to start it ~/src/op25/python$ ./audio_p25_rx.py -a I get this error message robert@robert-laptop:~/src/op25/python$ ./audio_p25_rx.py -a Traceback (most recent call last): File "./audio_p25_rx.py", line 34, in <module> from gnuradio import audio, eng_notation, fsk4, gr, gru, op25 ImportError: cannot import name fsk4 robert@robert-laptop:~/src/op25/python$ Can anybody please help me get the program running I am not great with software code and really need to get this up and running for a current project I am a part of. I am hoping this issue can be resolved with a couple of command lines. Thank You For Your Time and Help, Robert Klamp Jr.

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
