The Charlotte air traffic control feeds on liveatc.net have been removed. They would like to restore them. If you live within five or six miles from the airport (or even if you live further away) and are interested in providing a volunteer feed, please contact me or post here. I'd be glad to help online or in person, either direct assistance or answering questions. The cost is $200-300 depending on your setup. It's more or less the same as an ADSB feed, with a larger antenna, and you use a scanner and and USB audio input add-on instead of an SDR.
The Charlotte feeds did come back, but I'm bumping this today because we still need feeders and now most of the CLT feeds are down again. If you or anyone you know is willing to help, please contact me or respond here. Thanks!
