Hi,
apologies if this doesn't belong in Real Aviation (I think it does, but I could be wrong).
I recently purchased a radio scanner that is able to pickup airband frequencies, and am now looking to put together a list of frequencies used in my area (Sydney and the Illawarra, Australia) as I drive around a fair bit for work and want to program them into my scanner. My main question is, is there a good/reliable source for what frequencies are used by aircraft/ATC in different areas? I found http://airportdatabase.net/ and http://airportnavfinder.com/ but they don't seem to match in terms of what frequencies are listed for each airport (so I'm not sure if they're accurate and up to date). Is there something "better" I should be using than these two sites?
Also, what does "Activate lights only multi" mean at for example http://airportnavfinder.com/airport/YWOL/ (yes I am a complete novice).
