Where do you get your transmission from ?. We get ours from Emley Moor in Yorkshire and thought there might be a problem with that, but if you don't then it obviously can't be.
I live in Yorkshire so must be somthing to do with the mast at Emley. My Mum is having problems too. Normally says something on news if major problem but not noticed anything yet on radio or anything.
Ah ha just been on calendar website doing work at emley so no telly or interference until Thursday!! Too nice to watch tv anyway but at least the mystery is solved.
Actually just saw on Look North (while I was writing last reply) that programmes will be affected between 9am- 3pm until the 4th August. Cable and digital unaffected.
