From readme:

and GUI not work.

Thanks for the bug report. One clarifying question: did the error occur immediately after hitting enter on the command line? Or did you click anything in the GUI first?

First one.

I'm experiencing exactly the same issue, any workarounds yet?
I'm able to start the GUI, however, the graph stays blank after opening the provided test files.

I tried to reproduce this error with the following steps:

  • installing Ubuntu 16.01 LTS on a fresh partition
  • installing all system updates
  • installing gnuradio via pybombs (instructions at http://www.fieldxp.com/Chapter-2-Installing-the-Software.pdf)
  • installing other pre-reqs listed in README
  • running the following:
    ./waveconverter.py -q ../input_files/fan_all_dip1101_pruned_dec_c304p55M_s830k.iq -o ../output_files/test.log -g -p 3

I did see the "list index out of range" error, which must have slipped past my last regression. This error, however, did not impact anything, and I was able to hit the demod button and see the baseband waveform.

mnaujokas - does anything happen when you hit the demod button?
bdn76 - can you tell me anything about your setup? for example, how did you install gnuradio?

Thanks for your patience all.
