Do aircraft and folks on the ground talk to each other on 2 different
frequencies? I seem to hear the ground controllers and the actual pilot on
2 separate frequencies talking to each other.

Also, there seem to be a large number of frequencies to listen to regarding
aircraft around here, but which should I concentrate on? I'm just
interested in listening to the planes and the ground controllers and such.
