GASAX....anything over the Cairngorm is never a problem as We have a TX/RX site on the East end of the Moray coast. If you follow the A9 below the tops I will lose you northbound past Blair Atholl as I lose you on my TX/RX site that is just north of Dundee on high ground till you are in view of the Moray Coast TX approaching Newtonmore.
The Great Glen is hopeless below 4000ft.
Between Oban and Lock Fyne below 2500ft not good and around Ranok below 3500 ft not brill.
As you are aware VHF is line of site so if below the hill tops yes R/T could be poor........as I said in my earlier posts we really do understand the areas that we can expect to lose contact....its the only sector I do and having done it for the past 16 years I have a reasonable understanding as to what I am talking about.
As Mad Jock says I put a fair ammount of my own spare time and effort visiting Scottish clubs and inviting them through to our facility at Prestwick in an effort to promote flight safety.....may be one day you would like to join me for the day and see if you really think I know what I am talking about.
In the mean time safe flying.
