Hooking in on the discussion here. I struggle with something similar. I know how to work gnuradio, that’s simple enough. What i want to learn more about is how to configure my own SDR using gnuradio. So what the various blocks are used for, when to use what block, etc. I have experience LISTENING to an SDR using various devices, now i want to BUILD one myself. The final objective is to learn how to decode well known signals like the various HAM radio protocols like PSK31, etc. I know that all has been done before and the easy road is to take an existing flow graph, copy it and see that it works. But to understand what is happening is a whole different story.
So, without trying to hijack the thread, i am NOT looking for a gnuradio manual, i am looking for documentation on how to USE gnuradio for signal processing. Thanks for the advice, Ton.
