Glad you sorted, you also should find frequencies from participating parties and teams. I did similar stuff before attending large Air Show in Radom - Poland. Got frequencies for most teams attending and program into 2 scanners I have with me. Some are listed on various web sites, some on UK scanning forum UK Radio Scanning Forum • View forum - General Discussion just check under various postings related to Air stuff.
Good luck, Chris
