Been playing with FlightRadar today (definitely worth getting the paid app-it has a LOT of cool features!) and in the plane info I see the word Squawk with a number. Some planes have nothing there.
Also I discovered the app has alarms you can set, and again the word Squawk pops up. What the heck is a Squawk?

The other bit on that list Mode S is an identifier unique to each aircraft that is also part of the squawk and identifies the aircraft registration and type etc.
Some foresee it as a future system that may be used to bill you for flying, but they deny that.

A ‘Squawk’ is a four digit code fed into a transponder, so identifying individual aircraft on a Secondary Radar screen.
To save me time, have a read of wikipedia https://en.wikipedia.org/wiki/Transponder_(aeronautics) or make a “Google” search using ‘Transponder code’ as your key words.
When using FR24 one code to be aware of is 7700 – the emergency distress code – which can cover all sorts of eventualities from a major technical issue to a seriously ill passenger. On FR24 an aircraft squawking 7700 is shown as a red icon.
While serious researchers can have all sorts of issues with wikipedia entries, for simple inquiries it can be a useful encyclopedia to explain technical terms.
You might want to try and obtain one of David J Smith’s books on Air Traffic Control – try Abe books for a cheap(er) second hand copy. Lots of interesting detail on procedures and technology.
