Yep, this ATC live stuff has been around for quite sometime. I wish that all of the more popular airports would add their ATC in, as most of it is voluntary. It does take some money as it requires a server with decent bandwidth to broadcast (duh), air-band scanning equipment, and streaming software like HelixDNA by RealNetworks (RealPlayer) to compress, deliver, and stream the audio. Even though the audio stream doesnt require you to have a fast connection the RealNetworks streaming software itself, isn't really cheap, and with the amount of popularity a lot of these streaming audio sites take, the bandwidth fills up quite fast. I really like listening to Dallas Fort Worth ATC (http://www.simuflite.com
) and O'Hare ATC (http://www.cyberair.com
) and of course the local traffic here in Honolulu.
I was thinking about making a small (very limited bandwidth) Real Audio streaming broadcast of the Honolulu ATC airspace, containing HNL
Intl, Kalealoa Airport, and it's approach sectors. As I live on a mountain on the west side of Oahu and get great reception of a lot of the local and center frequencies. Only problem is the streaming software is quite expensive and I'm not sure if you need FAA approval to broadcast ATC streams over the net. Maybe I'll just email and ask some current ATC broadcasters....
