Can anyone give me a couple of hints as to how to choose which frequencies to listen to?
For example, ORD has multiple frequencies; if I want to listen to the one that will give me the most info about departures (as I await my flight) how do I know which to choose?
Also, I listen to CLE a lot; there is quite a bit of background noise (from other frequencies, farther away stations?) similar to what I get on marine frequencies when I do not have the squelch gain up high enough. Is this normal?
