Coalface,
This issue is under investigation. However, it has emerged that the problem only appears to affect one operator - I take it you fly the "blue" ones? If so, I believe that your technical people have/are approaching the competition to see what is different with their comms configuration/operation.
I hope thats Leuchars Radar you are talking to on 126.5 not Scottish Info!
.....and don't forget - if you are receiving on test only - its a Flight Information Service only!
