I can chime in regarding some weaknesses of the linked document. I approach this as a highly technical person, programmer, electronics tinkerer, and someone who has been actively exploring SDR for over a year now, with RPis and a few different SDR hardware and software types. I've become quite familiar with how "terrestrial" radio works from this period of experimentation, and I think most people who have ever used any form of analogue radio would not have much issue figuring out what's going on just by playing with an SDR and a length of wire as an antenna. I opened this document expecting some introduction as to how I might get started with radio astronomy. After reading the whole thing through, I'm left rather in the dark about what results I would be seeing if I were to go to the trouble of following the instructions and getting it running; - the document in parts seems to be a bit back to front. some of the concepts are explained after the instructions to implement them - it's full of technical jargon which is not explained at all - it doesn't explain how to interpret any of the captured data beyond "this small bump represents the milky way" - what else, for example could be observed with this equipment, and how does that differ from what's shown? - it offers no help as to how to figure out what's going on if your results don't match what's shown in the document - it offers no indication of where to go after carrying out just the one observation shown - there's clearly some text missing in the part about the analyse scripts and what they are supposed to do I could go on, but the above would be my main gripes with it; the result of which has left me with a feeling that this has taught me nothing about radio astronomy and no desire to build the antenna or use the software.
