My sympathy Wombat, glad it worked out.
But I have to agree with sleeper, the UK's finder of lost aircraft system needs to be changed, Guard Channel does not work with the plethora of Practice Pans, etc. Guard is too important in the world of modern commercial aviation. Any thing other than genuine urgency problems need to be moved away from 121.5.
Illegal transmissions need to be prosecuted and the UKs system needs to be brought into line with the global position on guard.
