Put your postcode into Digital UK - Coverage checker you will see that it's the SDN and ArqA multiplexes (on UHF 29 & 31) that are predicted to have some variable reception at your location either now or in 2020. You ought not to be getting issues with ArqB on UHF37.

My inclination would be to check your aerial installation and coax connections & do you have the correct group or high enough gain aerial? Also check you don't have any boxes (VCRs etc) with RF outputs down near those channels.

Yes it is the correct aerial, have tried a couple I can get to both a K (in use now) and a W (replaced an E at the 800 switchover in 2018).
I can also see the power drop from previous spectrum analyser plots of the W that saved off when I aligned using the SA after switching from the E.
C29 is indeed flaky at times too, as the predictor expects.

I am not aware of any C37 blockers, but will check again as that is of course the old RF VCR frequency.

My question was more why has a special radiation pattern been put in now, and how did a change that makes reception worse get permission ?
A coverage map by MUX would be interesting to see.

Bill:

I'm not sure that the radiation pattern has been changed recently. In any event that will be taken into account by the coverage checker. Because of the 700Mhz clearance see Digital UK | 700MHz clearance and the number of transmitters using a smaller number of UHF channels, then this will affect reception of some channels from some transmitters in some locations but again this will be taken into account by the coverage checker, maybe you need to enter your house number to get a more accurate prediction.

It's also possible you might have some very local issues affecting reception - a tall building, trees, nearby water tanks or solar panels, other nearby metal objects etc can all affect reception of signals.
Although it could depend on which Wideband aerial you've got, generally the Group K will have better gain at the low end of the UHF channels.

If you enable Pro Mode by the coverage map at the top of the page, you should be able to look at the pattern for each multiplex (click in the list), but again, as already mentioned this should be taken into account by the coverage checker.

If you have any devices with RF outputs, I would set them above UHF56.

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.

wendy shreeve: If you're referring to Sony Movies Christmas, it is broadcast on the local TV multiplex, which is not available from Sudbury as there are no local TV channels in any of the areas covered by that transmitter.

Dunno what's going on with the Sudbury transmitter - at first I thought it was either the weather or the new vast building on Sproughton road hampering my signal (which is in a direct line to Sudbury from my house) but in the past week or two I have had no watchable freeview signal each day other than the BBC channels until 10.15p.m each night!

If you have no satellite signal, see Sky Digibox says 'No Signal' or 'Technical fault'

If you have other problems, please provide a full (not partial) postcode (or preferably enter it in box at the top right) and indicate where if aerial is on the roof, in the loft or elsewhere.
