Not predicted? How so. The maps here say I should have full Freeview coverage under the Sudbury transmitter, and that I would also think is supported by people up the road from me having the channels I do not.
But regardless of whether I was "predicted" to or not the idea of the digital switchover I believed was to bring more TV to more people not reduce what they can receive.
To be as polite as possible - I despise people who pretty much stand up for the shambles for many that is the digital switchover by way of making excuses and pointing out things like "they're not covered by the TV tax".

An Irate Freeview viewer: Copy and paste the link provided below into your browser and you can see that the two muxes in question are missing.
As an engineer myself I disapproved of this having been done right from the start, and had voiced my opinion that it might well be OK as far as the transmitting side of the equation was concerned but certainly not if consideration was given to the problems that this differential in power is very likely to cause with reception, basically because of the average domestic tuner not being able to cope with this type of situation, although some brands do much more than others, Humax and Panasonic being amongst the better types.
However, as commented by Heinz your difficulty should be rectified on the 27th.

It's gobsmacking, all this effort that's going into sorting out Freeview and I just couldn't be bothered reading the posts immediately above mine in case they give any useful information. It's not like 21 pages of information might be relevant or anything! For crying out loud, I have to post now or I might notice that the answers are even on the same page!!!!
Indeed, why the heck would the engineers bother to increase the power on two muxes and move them to better channels that are easier to receive, putting them on a par with the BBC channels when they could just leave them the same as they are now and let people whinge.
For goodness sake people, if you're going to complain, spend 10 minutes, look around you and you never know, you might actually learn something (God forbid!!!) But I guess you'll just moan about the fact that it'll never work because it's the English thing to do to moan moan moan.
Roll on the 27th June when all the muxes are transmitting on the same power!

An Irate Freeview Viewer:
I live in Rayne (CM77 6) not that far from you and had a good 40-year-old Group B aerial until six weeks back when I finally switched to a five-element Wideband aerial (Blake DMX5 I think) with a channel 21-39 (I think) Antiference filter to remove any London reception, installed by Witham Aerials & Satellite (witsat.co.uk). Previously I could not get a reliable ITV4 (same issued with BTCC) but realised that an aerial change was the only option. I also had the old style of aerial downlead instead of the WF100 satellite style downcable now used. I now have a neat small aerial (awful-looking 10-element Blake DMX10's or similar were previously fitted), new downcable, and get all the channels without problem, even though channel 63 is down at 30% signal strength according to my Humax PVR. So, if you have an old aerial and old downcable the an aerial update is the only answer. Yes, it's annoying we are forced into this by the digital switchover, but it's something we all have to live with.
I can thoroughly recommend Witham Aerial & Satellite. He's an ex-Marconi chap like me and a professional installer, not like some of the cowboy installers.

Trevor Wright: The Commercial channels are on low power from Sudbury. Since last November there have been many reports through this website of people unable pick-up C63.
The changes due to happen this Wednesday will see all of Sudbury's Commercial multiplexes going to full power (finally!). As you know, this is around a year since Sudbury switched, but it has been in this "temporary" low power state.
For this reason I suggest that no changes be made until then, when an assessment of reception of the final-state signals can be made.
The three Commercial multiplexes will use 56, 58 and 60 which are above the former analogue Group B channels, and so may be outside the officially-designed range of many aerials, but because digital reception is all about getting sufficient level above the threshold, then this "may" work fine when the signals go up to full power.
