With my FTA satellite setup I've noticed that many of the news choppers encode a digital squaking signal in some of their audio carriers.

what is this signal (you can clearly hear it in the attached link's video... may wanna turn down your speakers) and is there a way to decode it (if it's not encrypted of course) and how?

New York Videos, NY News Video, Video Clips | NBC New York

(on an offtopic note, whether you agree or not with the occupy movement this is a very interesting way of getting your message out. legal or not.)
