I've had really bad performance on freeview since just before Christmas. Before the performance dropped, I could get all the channels. Now I have lost all the BBC channels, and cannot get ITV1 or 2. Autotune on my tv is not able to pick up these lost channels. The comments on this forum suggest there might be a widespread problem in the area served by Sandy Heath. It is a bit worrying, as we are due to begin the switchover in March.
I live in Soham, just outside Ely.

Similar Sandy Heath reception issues here in Cambridge.
Signal levels have dropped a little and pictures from the lower power muxes are breaking up on the TV.
My Topfield PVR and Bravia DTV both report same lower signal strength than normal when looped through on same antenna, and when plugged into it individually.
No changes in loft antenna, and no environmental changes on the wall that it points through.
This effect has been happening sporadically over the past 4 weeks. So far I assumed it related to power adjustment tests prior to analogue switch-off.

I concur with Mark (and many others) above. I live close to Bar Hill on the A45 in Cambridgeshire and have suffered exactly the same problems as those in the past few posts. Having consulted many relatives who live in the same area, they're all experiencing the same problems too.
How can it be all of our equipment suddenly becoming inadequate to receive Freeview from Sandy Heath when we're all experiencing the same problems? It makes no sense. :s

Leanne: If that is the case, then I would suspect the comment elements that all of the TVs share.
