Can anyone tell me why we have this page for questions on Sudbury? It is confusing as we already have one called freeview from Sudbury transmitter.

Nick: Originally all transmitters offered an analogue service, usually on four or five channels. Each transmitter therefore had its own page dedicated to the analogue switch-off. Additionally there were 80 transmitters which offered a (usually) low power Freeview service. These transmitters had the "Freeview on the Sudbury TV transmitter" type pages to give details from the viewpoint of a digital household. Following DSO the analogue orientated pages are re-titled "digital TV transmitter" with details given for the replacement digital services, the Freeview orientated pages being similarly up-dated to show the current situation.

@John - The answer to your question is that power on Sudbury is increasing again on 27th June. At the same time as the power increase, ArqB (the multiplex with those channels) will move from its temporary frequency of C63 to the final frequency of C56, which also is a lot easier to receive.

I just had a TV repaired (well, if you can call a software upgrade a repair) by Andrews TV of Colchester (another very reputable company).

The job sheet states they'd updated the software and re-scanned for channels and yet all Arq B channels were missing when I got the set back - so even the professionals are still having difficulties!

Heinz: Purely out of interest I was wondering what model of TV you had this work carried out on?

Of course the other thing is, that if they re-scanned the TV it could well be the case that Andrews TV is not necessarily located in a best reception area as far as picking up the commercial transmitters are concerned, especially the exceptionally low powered ArqB Ch50 that doesn't increase in power until June 27th.

That said though, "if" you see EPG12 (Yesterday) on the programme guide then they are receiving it and you are not, however if you do not see EPG12 then they haven't received it either, and so you could try retuning the TV yourself just in case you are in a better spot.

We live approx 2 miles inland just outside Clacton on Sea. I fitted a new Satgear Alpha Mini High Gain HD Aerial on the roof about 5 weeks ago fed I belief by the Sudbury transmitter. The reception has been a Hugh improvement over my old Aerial. However on Sunday 27/05/12 we had reception problems on most channels on both our TV's just for that one (hot & humid) day, although checking this site there was no problems with Sudbury. Would this be due to weather conditions?

Landlubber Dave,Clacton on Sea.Yes is the answer to the question you asked at the end of your text.The inversion effect was the most likely cause !

Landlubber Dave, I quite agree with your statement that problems with reception only we have noticed this over the last week and seems to be confined to BBC channels only. When I say reception problems I really mean no BBC channels just a blank screen. I know that some one has mentioned this before "do not rely on this signal" I am talking about signal strength on Digi-boxes, the signal strength indicator kept jumping from 50% - 20% also when I re-scanned the box I was picking up signals from lots of different places i.e C30's C40's C50's where I don't normally pick them up. BUT what is the point of digital signal if I am unable to watch TV at night regardless of weather conditions!
I'm hoping that once the signal is boosted next month I will get some normality as I cannot receive most of the lower power signals at the moment. Ariel on roof & old Digibox which works OK in the day!

Seems like the Dutchmen are at it again, hoped this would go away with digital.
