Hi all, I'm still trying to get used to things on Gnu Radio and i'm ready to jump into making my own "tweaks". I am trying to duplicate a scanner that I saw on YouTube. ( https://www.youtube.com/watch?v=r9GtAFn5UlY ). The question that I have is regarding printing out of values. For instance if i'm parsing a tuning list that I can query from python, how can I display it on the graph. Or simply print out the frequency that I'm currently tuned to. Seems simple, but most things that I see online imply that I actually have to create a new block to perform this type of functionality. Is this the case? Can anyone point me to a good starting point to do this?
