Ok, thanks for that info. Do you know how much a scanner setup that feeds liveatc typically costs? I know some people that are putting some equipment at IAH and it might make sense for them to include voice frequency access. It would be on the airport property so the antenna could maybe be something pretty simple?
Any simple police scanner will work. Many Bearcat/Uniden and Radio Shack options exist - all over eBay for $40 and up. I like the BC-350A units and they can be had for around $50, sometimes less.
