I'm at LS17 9LP (Yorkshire). We've had digital for 3 or 4 years, and have recently got 2 issues. They have happened since I followed the on- screen instructions to re tune after 20th August.
Firstly - the digital signal fluctuates during the afternoon. From midday until around 8pm, we get breakup or even total loss on all channels. Reception is perfectly good the rest of the time.
Secondly, since we retuned, our "local" news on BBC (channel 1) seems to think we live in Lincolnshire. To get the Yorkshire news, we have to tune to channel 825
We have a wideband amplified aerial mounted on the wall of the house, horizontally aligned pointing at 194 degrees (to Emley Moor) direct into a sky box. The signal goes from there into a 4 way splitter for distribution to sets around the house. This configuration allows sky to also be distributed on analogue.
Any ideas why we get this fluctuation, and why the locality has changed?

Our Aerial is on the roof and since last October the slightest bit of wind has caused disruption to our service, we live in a windy area so this happens alot.
I see from this website the Llanddona transmitter has been have engineering works since about the time the interruption started.
How long will it be before the transmitter will be interruption free.

We have a bush freeview plus box. All of the channels play very clearly, but none of the BBC channels display any Event Information, which means we do not know what is going to be on, and cannot set Programes to record. All other channels are okay. Our previous freeview box did display BBC info. We have tried changing the box for a new one, and tried it on a different tv, but get the same result.
