John Broad: What do you mean by 'blotted'. If you mean they have vanished, then its more likely that your aerial has a fault. Try checking the connections and see if they come back.

You say you can't access the menu - is that because the remote doesnt work, or because the menu is locked with a PIN number? If you can find the manual, or simply give us the model/make (we could possibly find it for you online), then you might be able to reset it.

If the TV really is beyond help (and I suspect its not), then another decent 32, from a good brand (like the Samsung 32M5500), will cost around 300, and you can get that set up and tuned as well.

Having invested in costly equipment to get Sudbury rather than my local relay so as to get the full list of channels, is that transmitter ever going to live up to its name of a full service and give me the last multiplex so I can see Al Jazeera again?

Nick Horrex:

If you mean when will it get COM7 and COM8, the answer is never as those mulitplexes are temporary ones offered only by 30 main transmitters and covering about 70% of the population. The plan is that the channels carried by those multiplexes will be included within the arrangements for when the adjustments to accommodate the loss of the 700MHz band, expected between now and the end of 2019. No definitive dates have been given as yet.

The list of Freeview transmitter changes 2017-20 Upcoming Freeview transmitter changes 2017 to 2019 states that PSB1, 2, and 3 will remain on their current channels after next year. The table above indicates that they will move. Which is correct?

thanks, Mike P.
There seem to be several empty channels. It is a shame Al Jazeera does not use one.

I think I have checked everything . My question is why am I receiving Meridian Local news on 103 HD from the Sudbury transmitter ?

Mr Paul Bradley:

The HD services are not currently available with regionalised news services, so the broadcasters are using a 'general' setting so there are not any blank screens. Local regional services are available on the SD versions, on channel 3 for example instead of channel 103.

It is expected that when the forthcoming alterations to transmission arrangements take effect then the broadcasters have the opportunity to 'regionalise' their HD offerings.

I have a high gain triple boom aerial on a pole attached to the rear of my property approx 20ft above the ground pointing to the Sudbury transmitter..
All channels work except for the bbc channels which keep breaking up. if i point the aerial to the local transmitter they work fine but of course i cannot get all the other channels.
I have a 4G filter fitted and have tried all the reseting and retuning options available to me without success.
I suspect my aerial is picking up both signals from both transmitters but have no idea how to overcome it if that is the case. I have searched the net without result except some suggestions that this may be the case.
Hope you can advise.
many thanks

David Thorne: Firstly, have you checked that your TV is tuned to Sudbury on UHF 44 for BBC channels rather than Clacton on UHF 49? Also, what signal strength and quality readings do you get? According to the Digital UK checker, from next summer the Clacton relay will be gaining the COM4/5/6 multiplexes so in the long run you would probably be better off turning your aerial around, particularly as reception of Sudbury appears to be getting worse at your location from 2019.

I think your table for "How will the Sudbury (Suffolk, England) transmission frequencies change over time" is incorrect for the right hand column.

It shows all muxes changing on 31st March, which seems to contradict the Digital UK and Ofcom information.

Ofcom shows that the channel allocations will eventually become:

PSB1 - 44
PSB2 - 41
PSB3 - 47
COM4 - 29
COM5 - 31
COM6 -37


But doesn't give any dates for the change(s)

The DigitalUK site says that the only currently definite change is tomorrow (7th February), not the 31st March, and that it is only COM6 that is changing at this stage:….pdf

It is probably worth updating your page to prevent alarming people that all the PSB muxes will be moving to frequencies not receivable with an old "Group B" aerial!
