Hi Desmond,
I have a similar CS background combined with a youthful interest in radios from the distant past. I initially approached GNUradio with a similar attitude, i.e. it's just software, I can figure out what it does. But sadly that is not true, and as Martin Leech points out in a different reply on this thread, GNUradio combines expertise from many different disciplines and you need some level of familiarity with all of them to extract the maximum utility from the package. With my knowledge the mechanics of writing an OOT module and getting it to show up in GRC is fairly simple. It's the knowledge of radio signals and digital signal processing where I have the most difficulty. To address DSP I bought the Richard Lyons books and am working my way through it. I strongly recommend that book for the harmony between theory and practice in presentation. I am simultaneously going through an online course on electrodynamics hoping that when I'm done I will have the ability to use GNUradio efficiently in interesting ways.
