Dale: Thanks for the update, judging by what you report its obvious that local variables exist to what the actual post code predicts, Ch49 being the best example of this.
What you find after the 20th will be interesting, as after then only MuxC (Ch54) & MuxD (Ch50) are indicated as being variable, although on September 11th MuxD changes over to good reception, with MuxC staying as being variable until 27th June 2012 when it also joins the category of "good", that is as well as changing to Ch60.
Ch49 on this same date changing to Ch58 8k operation, reception jumping to 100%.
Pity about the TV having a single scale indication, this not really being any use except for crude indications of what is happening. Regarding the scart gadget, I only asked as I wondered if it was one of the originals as there are a few types about nowadays.

Snail : are you sure you're still getting C4 and C5? They are all on the same very low power Mux (with others) until Weds morning, and loads of people are not getting them at the moment. If it really IS only ITV1, then that's very odd.

Thanks for your extremely helpful website information and contributors' questions and answers. It has certainly been far more useful than digitaluk and that annoying robot!

Hi Everyone,
Just checked the Digital UK website for my postcode (we live in Clacton), amazingly they predict that my reception will get better on 16 November this year, then gradually worsen until 2012 when only 10 channels will be 'good'
This seems ludicrous, I've retuned this morning and all seems good signal strength wise from Sudbury and Clacton transmitters, except for the Film Four mux (50), we already use a booster and at least ITV is now coming in strong, but it seems rubbish that according to Digital UK by 2012 the channels that are 'variable' increase to 59 from 45 today.
I thought switchover was supposed to make things better not worse ?
Sorry for the rant, and thanks for this great website, very useful.

Hi,
I live in the SS0 post code area before DSO today I had a decent signal across the board using a high gain wideband Ariel pointing at the Sudbury transmitter. However, since retuning this morning the signal on channel 50 is very flaky al the the others are fine, is there any reason for this?
Thank you in advance

My digital aerial is on our roof. Before switchover I could get more freeview channels than I can now. Now all it does it break up and some previous channels I now cannot get.
Is the signal likely to get any better.
My neighbours freeview is the same!
