Thanks Jason and Lezam,
Lezam: unfortunately no its not a major airport with jets and stuff, nor is it an international one. It is a training airport where pilots learn to fly, however its an incredibly busy airport (its Parafield Airport, if you have ever heard of it).
I also don't live too far from the Edinborough RAFF base but I don't know if the receivers that most people would use here would be able to pick them up.
I have another question, I did some calculations and worked out that if a stream used approx 16kbps, that would use around 5gb a month of bandwidth, is this true? for me it just seems like to much usage.
