Hello,
I love liveatc.net. It's such a great site and I'm so thankful for a place where I can listen to ATC from so many places. I like to try and follow various planes as they go from takeoff to landing, KCLT to CYYZ, for example. Looks like the first transfer after KCLT departure is to ZATL on 134.55, but this ZATL sector isn't on liveatc.net, so I'm curious as to what the criteria is for which frequencies get covered. I know there's so many frequencies and not everything can be listed, I'm just curious as to what goes into such decisions.
Thank you for your time, and thanks for the great site.
