I'm a newbie at DSP. I am starting a hobbyist project where I plan to monitor 100's of wildlife radio collar frequencies (at my job) and record how many "beeps" per minute are received. My software budget is zero. I have been starting to learn GNU radio and I find most of the tutorials are from 2012 and the many of the blocks are no longer here or soon to be deprecated (WX GUI). Also notice it is not a common tag on Stackexchange. Is GNU Radio a good choice for me?

    $\begingroup$ GNURadio is in active development and has an active community. It's a very good choice if it supports your hardware. The downsides are (a) very little documentation and (b) it's hard to get started writing your own blocks. $\endgroup$ – MBaz Mar 19 '16 at 1:45
  • $\begingroup$ @MBaz Would you suggest the best forums for basic "why didn't this work" type of questions? Would it be here? $\endgroup$ – John Mar 19 '16 at 3:53

    $\begingroup$ For gnuradio-specific questions I'd go to the gnuradio mailing lists. They're pretty high traffic. If you need more in-depth help with the theory I'd ask here. $\endgroup$ – MBaz Mar 19 '16 at 23:27
  • $\begingroup$ @MBaz Very little documentation … I could kind of agree on "hard to access documentation", but with the Guided Tutorials for beginners and the really well-citation-backed source code algorithms, I don't think it's the worst documented SDR choice :) $\endgroup$ – Marcus Müller Apr 8 '16 at 9:05
  • $\begingroup$ @MarcusMüller It's true that some of the tutorials have improved a lot recently. $\endgroup$ – MBaz Apr 8 '16 at 13:40
