Adam.. I didn't bother to listen but it sounds as if you were breaking the law by listening in to the airband...
Am I breaking the law by watching and listening to this YouTube clip?
Please give it a rest now HD.
Yes it's against the law - but everybody does it and have been doing so since I was a wee lad spotting at BHX back in the sixties. Never but never did a police officer (or anyone else) ever challenge any person listening to a VHF receiver.
