Thanks all.
Mike, DFC thanks. I am resolved to follow your advice and get to grips with the latest AIS site: I gave up trying and went across to graphing apps after the difficult initial launch of the Mk1 AIS interface.
As it happens I
had rung the 0500 number, but did it the night before the flight (Friday night) at about 20.30/21.00.
So now that will have to done on the day of flight in future.
