We have lost on Dave, Pick TV, Dave Ja Vu, and some other in these groups since mid August - the signal is so poor that at best we get very broken up block segments and short sound bursts. What has changed the transmission on these?
is fine, cables OK, working OK, retuning doesn't change any of these and all other groups still received fine!

J Skelton: Your problem could be related to the fact that works have been taking place at the Sandy and indeed will also be doing so next week, this resulting in the service being liable to interruption such as short breaks in transmission or other issues that can affect .

Unfortunately nothing has been posted on the engineering board as far as an estimated date for the completion of the work is concerned, it would though be prudent to check with a neighbour or some other person nearby purely for the purpose of verifying that the problem is "not" just confined to your installation, albeit its unlikely that it would be!

Hi

Thanks, I think you're probably right. All the other are perfect but every BBC channels suddenly went dead. It must be the BBC but I am just hoping it's temporary.

My Grandparents in Stony Stratford/Milton Keynes (Not sure on Post Code, sorry!) also report loss of main , such as BBC series channels. Haven't been over to check for potential "user error", but apparently zero outta nowhere.

Lost service for 5+ hours yesterday afternoon/evening on BBC1,2,3,4, ITV1,2 Channel4, 4+1 and Channel5 . Gradually came back after retuning box several times. This morning (and still continuing) am losing BBC1. I'm tuned into which reports no issues! How come??
