MATZ squawks
I've just returned from Wickenby and was working Cottesmore. I asked for Flight Info and was given the squawk 4640 (I think). A few minutes later another a/c came on frequency and was given the same squawk. I queried this and in the nicest possible way the lady controller informed me it was the common code for Flight Information Service ex Cottesmore. Whenever I've done this before the squawks have been sequential e.g.4640,4641 etc. I would have thought that 2 a/c using the same squawk would have caused confusion or am I missing something?
