Aargh.. gremlined.. didn't spot the typo as off the computer for a few days. I meant of course 1 second.

Regarding the airband...not my cup of tea, but I live right under the London - Europe main flight path so have checked them sometimes. Even with a scanner it is a bit like playing the "wack-a-mole" arcade game. Now you see it - now you don't. Often the scanner was in a different part of the band.
