I had to add the frequencies to those other screen shots myself. I don't have any with the frequencies added for Chicago or Atlanta. From my notes this is what I have for Chicago, these are confirmed by listening and are current to a few months ago. I haven't had a good listen to this area since RVSM, so the altitude ranges are incomplete. Any updates or corrections always appreciated.

I don't have access to any radios in range of Atlanta so I can't confirm any of their frequencies. This website is the best reference I've seen, but I can't confirm how current it is.
