Roydonian, A Decore: These channels are carried on the ArqB multiplex. This is using the channel that Multiplex B used before switchover, so if you had problems with that (BBC Four, CBeebies, BBC radio stations, Sky Sports 1 & 2) last month, it's not surprising you're having trouble with ArqB now. In addition, ArqB requires about twice as much power to work as Mux B used to, so if Mux B was marginal, ArqB is likely to not work.
If you provide a full postcode we can see if this temporary location is expected to work for you, and therefore you have a problem with your installation, or if it's just not practical to receive it at the moment.
The multiplex can't move to its final location, C48, as that's being used by low-power digital services at Sudbury until mid-July, Belmont until mid-August and a number of Sutton Coldfield's relays for BBC Two until 7 September.

Postcode mk46 5es, we have a Sagem PVR 7280 T digibox.
We lost BBC for 10 days initally, as of the 10th it returned with pixellation on all of the BBC channels all of the time: very bad in the evening with the sound and picture really distorted.
We are regulary retuning but often only pick up 40 channels, max we have achieved is 102. The signal power values are way down when we check those. All of our neighbours are on Sky or Virgin so we have nobody else to compare to.
We are on a hill at one of the higher points in the town; we have checked the leads on the tv etc. and our aerial.
Is there something wrong with the signal strength from Sandy Heath, or could we be getting interference from a relay station? Is there something we may not have considered? We were about to buy a Humax digibox - maybe a more up-to date system would be a solution?
Thank you!

The charts (or graphical) information on two web pages for the Sandy Heath transmitter ( Sandy Heath digital TV transmitter | ukfree.tv - independent free digital TV advice and Freeview on Sandy Heath TV transmitter | ukfree.tv - independent free digital TV advice ) are still rather confusing, even though the initial error re. C67 (Arqiva B) has been corrected since the early hours of April 13th.
But why show the TEMPORARY (i.e. currently correct) frequency for Arqiva B yet show the FINAL 'resting' frequencies (i.e. currently incorrect) for Arqiva A and SDN. I realise that the " NOTE:" underneath the charts explains all, but, as they say, "a picture paints a thousand words....."
We need some kind person to put charts in for 13th April to 30th August 2011, 31 August to 13th September 2011, 14th September to 22nd November 2011, and 23rd November 2011 onwards.

adrienne -
Your postcode on the Digital UK postcode checker suggests 100% reception. You may have too much signal, and a plug in attenuator may be the answer. BBC channels went full power on the 30th which is when you say the problem stated.

Yan Lee: Unfortunately the software really only supports 'before Freeview' - 'low power DTT' - 'after switchover'. It wasn't designed to support so many changes both before and after switchover.
The only exception I can think of is Rowridge, which shows before and after 25 March 2009.
Digital UK's postcode checker (trade view) shows all events that are currently planned, and what that will do to your reception.
We're also somewhat behind Digital UK in terms of information because the broadcasters are changing it at the last minute and Ofcom aren't keeping up. Other than scraping the DUK trade view, there's not a lot we can do (and DUK don't publish the power levels). (DUK is mainly a front for the broadcasters.).

Dave: Sandy Heath is at a bearing of 198°. However, Waltham (East Midlands) or Belmont (Yorkshire & Lincolnshire) are expected to give better results.

My strongest signal doesn't bear any relationship to these channels. My topfield recorder has found channels
27 Mux1,
24 Mux2,
43 also described as Mux2,
40 Mux C,
67 Mux D,
48 described as RF.
What's happening?
