The Scottish FIR Sector sector covers airspace from the Lakes to the Moray firth so the rest of our transmitters are further north. London have coverage over the Lakes as technically it is their airspace but to be honest most folk will not talk to them as they are far too busy with traffic further south...I.E crossing the English Channel!! Only if you are really low and down below the summit heights is the coverage poor but in general I rarely lose contact with traffic above 2000ft. In general as I said before we have an unofficial agreement that Blackpool and Warton will hand traffic to Scottish Info over the south Lakes for north bound traffic and we do the same to them with traffic heading south.
