The symbol shows the location of the Sudbury (Suffolk, England) transmitter which serves 440,000 homes. The bright green areas shown where the signal from this transmitter is strong, dark green areas are poorer signals. Those parts shown in yellow may have interference on the same frequency from other masts.

Are there any planned engineering works or unexpected transmitter faults on the Sudbury (Suffolk, England) mast?

Why is it that the sudbury transmitter is broadcasting ITV Anglia on SD but is broadcasting ITV Meridian on HD? I'm sure that it was broadcasting ITV Anglia HD but a few weeks ago?

Thanks,
Ben.

Ben: ITV Anglia HD has never existed on Freeview, it is only available on satellite (presumably you saw it being received via a Sky or Freesat box). There are only a handful of ITV HD regions broadcast on Freeview, resulting in many viewers seeing the wrong ITV HD region.

I assume that Channel 50 Sony Christmas Movies is not yet available from the Sudbury transmitter.
I would be grateful if you could confirm this and, if so, advise if it is likely to happen in the future.
Thank you,
Brian Goody

Brian Goody:

Back in the summer, Sony moved a number of their channels on to Local Multiplexes and this was one of them. For a full list of channels and which multiplexes they are on see Channel listings | Freeview

That list will probably update on Nov.5th & 14th because according to Freeview
"As of 5 November 2019 there are changes being made to the way Film4+1 and More4+1 are being broadcast. In order to keep receiving these channels you will need to retune your TV."
"As of 14 November there are changes being made to the way E4+1 is being broadcast. In order to keep receiving this channel you will need to retune your TV."

Both of the above are highly informative NOT! I shall endeavour to get more precise information!
Sudbury does not transmit any Local Multiplexes or the COMs 7&8 HD multiplexes and AFAIK there are no plans to do so at this time.
