If you have a scanner, you can use the frequencies below to listen into ATC communication. Use RAMP frequencies to hear push back requests and early runway assignments / requests. Use Ground to follow the aircraft taxiing outside the ramp to the runway. Use Tower to get the actual runway clearance for arrival and departure.

Approach and Delivery will be added soon as well, but these are depending on approach patterns and require basic ATC knowledge to be able to follow up on them.
