Depends on what kind of scanner and antenna he has. The Scottish control freqs are funny things - I can't pick up any controller comms in Fife or Edinburgh, but in Dundee I can get high level aircraft and all controllers on one particular frequency with a handheld and the magmount on the car. I believe there are a couple of sites around Glasgow though so I'd suggest giving it a go, seeing what you can get and possibly posting some clips!
Just out of interest Bono, what scanner/antenna setup do you use? Do you record your clips down at the airport or at home?
If I can be of any more help, please don't hesitate to ask - In fact if you post a question the whole community tend to be pretty useful people
Oh- Meant to say - Sorry if my little tutorial came off a bit like it was written for a two year old - I have no idea how good you are with computers so I was just trying to make it easy to understand. Was reading it back and realised it sounded a little condescending!
