Cynthia harris :
As per the post before yours, the Transmitter is on Planned Engineering. Service interruptions are usually short, considering the time of your post, I would have expected signals to have been back some while ago.
Unfortunately it looks as though the Planned Engineering continues next week so there could be further interruptions.

Robin Buddle: According to the post above yours, there was engineering work taking place at Sandy Heath last week, although I can't see anything to indicate whether the was has been completed or whether it is continuing this week. Have you checked for any loose or damaged cables and connections behind your TV? Do not attempt to retune.

In normal circumstances you should be getting very good signals from Sandy Heath.
The other things to check is that your aerial looks intact and is still pointing in the correct direction (for you, bearing 192 degrees - that's about 1/2 way between SSW and due S) with the rods (or squashed Xs) horizontal. Also that the downlead is secure and not flapping in the wind.
