Nice. Sounds like a fun project! All planes are required to have ADS-B transmitters (known as ADS-B OUT) by 2020 if they fly above 2500' (that height is probably U.S.-specific).
Those that fly above 18k or outside the U.S. must have the 1090 MHz frequency. In the U.S. if you fly above 2500' but below 18k, you can use the 978 MHz frequency. I live and work near a county airport and have seen transmissions on both frequencies, but most is on 1090. I have dump978 attached to dump1090 port 30001 and sending packets into it, but don't know yet whether dump1090 combines that input with its own when it sends decoded messages to port 30003, the port I'm pulling from. It does say that it combines them on port 30002, but that's the binary output port and I don't currently decode that. To test 978 I need to bring up dump1090 w/o any hardware, then use dump978 w/hardware to send to dump1090 and see if I get anything out with my script. Been having too much fun listening on the 1090 frequency and don't want to stop long enough for that test! Particularly since the 978 packets are much less frequent. If anyone else tries this, let me know what you find out.
