David W: As you see above from the multiplex listings above, Sudbury is not scheduled to broadcast com7 - you'd have to pick it up from another transmitter - see: Freeview HD extended service from 2014 (com7) | - 11 years of independent, free digital TV advice

Michael: That's what I was originally assuming.

But I've been told differently today but a few people...hence the confusion.

What has happened to my signal. I see there was maintenance in October. Well since then our signal has been poor for our little wall mounted tv in the kitchen. It used to be fine now we are having to move the aerial all over the place to obtain a signal at all. Whatever you did, please undo it.

What a letdown..didn't realise I wouldn't be getting only BBC 3 HD from Sudbury glad to have the new channels via Sky, I learnt to always expect disappoint first from Freeview in Chelmsford, where I live Sudbury is the only option.

Am I reading the initial plans displayed on the initial part of this page correctly - i.e. Sudbury may get com7 and 8 at some point after 2014? There is little or no option for me as I live in Hadleigh (Suffolk, not Essex). Tacolneston doesn't quite cover central Hadleigh (and it would be an incredible reach anyway, it's right on the edge of theoretical coverage).

It's not the most massive loss, BBC4 HD is really the only channel I would like. BBC3 HD has been up and running perfectly since it should have been.

Gareth: Due to the proximity of this transmitter to others in France, Belgium and Holland, Ofcom has not been able to get clearance for the provision of services on the Sudbury Mast.

It is not expected that such clearance will be granted before 2018.

Thanks for the reply - oh well. I suppose that's why we've got the 1,001-ft mast at Mendlesham doing nothing apart from mobile services and rubbish local radio? Seems such a waste.

Obviously I know that you and your sources know what you're talking about, but it still seems strange that Sudbury would interfere with the close continent when, for example, Belmont won't. I suppose that's just the key distance further west?

It is ironic that Sudbury could interfere with France and Belgium but it has a few black spots in Sudbury itself (as I'm sure you're aware, the transmitter isn't really that close to Sudbury) and indeed Ipswich, which is ~10 miles away. If you approach Ipswich from the West (Sudbury) then most people approaching the town centre on London and Hadleigh road have their Yagi aerials vertically mounted and pointed at the Bramford (Bullen Lane) relay - which almost implausibly, is actually a Tacolneston relay. Some people furthey into town from the west, and out of town closer to the coast actually have theirs pointing at the minor relay on top of the AXA building in Ipswich, or the Felixtowe relay.
