IO540, it doesn't do it by looking at the text of the Notam, so it doesn't matter how they spell it.
As for the Red Arrows moving around, one of my favourite RT moments was when they called Luton late one evening on Elstree's frequency and as Elstree was shut I got to tell them that they were on the wrong frequency and 'helpfully' offered 129.55 instead. We all make mistakes, though having seen their displays it seemed to me that they really don't make very many.
