If you want radio now you have to put a 0 in first and got an extra digit (DS1 just showed me that, I'd never have known!) so R1 is 0101, R2 is 0102 etc.
Kirsty and Phil etc are now on 250 onwards.
Sky News is still 501 (of course that wouldn't change!) but the others have all squeezed up.
We pay them enough, FFS, why can't they send us a list of old and new numbers?
