You can also pick up a flightaware dongle, they have extra hardware inside of them that lets you pick up aircraft a bit further out/with more information. Benefit if you pick up one of those normal sdr kits from nooelec is that it comes with antennas. Easiest way to start is to take one of the antenna and trim it down to 14cm and stick the magnetic base on the roof of a car.
