Thanks Chris.
It seems to me that freeview is going round in circles and that if we had retained the old group B aerials they would have done fine.
i do not understand how they can fit in all the channels nationwide when 48 is now the highest. I recall arguing that Aldeburgh could have been full freeview and was told not enough channels.

chris : The encoders on the PSB3 multiplex are set to switch between 1080i and 1080p dynamically depending on the pictures they are encoding. HD channels on satellite only use 1080i as Sky HD boxes don't support 1080p.

I think he (a different chris) just clicked on the last post comment which then uses the name of the previous poster in the reply, which as it happens was you. Nothing to do with your previous posts, just something he'd seen and didn't know why.

David Charles Rogers:
There doesn't seem to be any reported faults that I can find, nor is Sudbury listed for Planned Engineering at present, however there are weather conditions that may affect some signals for some at this time, but if this is a regular problem rather than one that's just occurred that's probably not the case.
Which channels are you noticing the problems with?
Your location is predicted to have possible variable reception for the SDN/COM4 & ArqA/COM5 multiplexes.
See Channel listings for Industry Professionals | Freeview for TV channels are carried on which multiplexes.
It may be worth checking in your TV tuning section that you are correctly tuned to Sudbury's UHF channels as more than one transmitter could be picked up at your location.
The correct UHF channels are as listed at the top of the page.
If your tuning is all correct, it would be worth checking with your neighbours (as you are most likely on a communal system in a block of flats) to see if they have the same problems. Even if they don't it might be a good idea to speak to the management about getting your connection checked out, or the whole installation if neighbours have the same problem.

We live in Howe Green Chelmsford and have had no picture on two of our Freeview T Vs for some time. I was told it was because the Sudbury mast was being repaired, I have tried several times to retune it without success. Our Sky TV is fine. Is there any way this can be rectified? Many thanks, James Knights
