What would i use GNU Radio for?

picking up airplane position-indicator feeds with a DTV USB-stick and mapping the into a display in an rPi?

  You could use it for that but there is software made specifically for this, like dump1090 for Linux (here for other options: https://www.rtl-sdr.com/adsb-aircraft-radar-with-rtl-sdr/ https://www.rtl-sdr.com/adsb-aircraft-radar-with-rtl-sdr/)... What I found funny when I tried it is that many small airplanes don't broadcast that signal... are they FBI's planes? Another interesting use can be reading your electric meter (and the ones of your neighbors), using GNU Radio or https://github.com/bemasher/rtlamr https://github.com/bemasher/rtlamr . Another one, is reading TPMS from your car wheels (or cars that are passing by): https://www.rtl-sdr.com/receiving-decoding-tire-pressure-monitor-systems-using-rtl-sdr/ https://www.rtl-sdr.com/receiving-decoding-tire-pressure-mon... , https://github.com/jboone/tpms https://github.com/jboone/tpms

    Half of the fun is implementing the radios yourself, it's a great learning exercise.

      For me it is a quarter of the fun.... much more fun to see all the data that is available to anyone over the air....

You use it to program/run a Software Defined Radio (SDR). SDR makes radios cheap, versatile and programmable. As a non-licensed radio operator you can get a cheap USB connected receiver and use GNU radio to receive, demodulate and decode all sorts of signals. It's fun to learn about how to decode certain signals. You start with a simple AM demodulator to listen to music stations and before you know it you're tracking airplanes and hacking keyfobs.

You can do arbitrary processing of radio signals, from basic FM radio decoding to interpreting images of the earth from space sent by satellites. You can also figure out the protocol for toy RF cars / boats and control them from whatever software you like. It's a really powerful and cool way to explore the EM spectrum around you right now.
