jh: You don't seem to be in an "offical" Freeview reception area yet. And even after switchover, on 23rd November 2011 you are still not predicted to have excellent reception, other than on Multiplex PSB1.
The transmitter has no faults.
There is currently weather conditions causing Inversion, see What is the Inversion Effect and why does it effect my Freeview TV reception?

To be honest, you would be best switching to Freesat.

Thanks for your comments. What you say is exactly what I understood to be the case - a big increase in transmitter power and one that should improve reception for us bog dwellers enormously.
Haven't looked at your ss map again but shall do later.
Again, many thanks.

You certainly did!
I note the ss map hasn't, yet, been updated (it still shows a fall in strength post DSO so shall take another look later; ITM, the numbers you supplied do the job.

Brian: why don't you just remove the erroneous NEW7 and NEW8?
There is no date even set for interleaved spectrum auctions. There is no guarantee that the spectrum auction will be won by any TV provider. The speculative allocations - and they were only ever suggestions - will have to be completely redone, since channels 61 and 62 are now to be released for mobile phone use. Previous allocations of 61 and 62 - either to existing muxes or tentative interleaved allocations - are planned to be moved to 49 and 50, and 49 and 50 to 39 and 40. However, some transmitters that haven't yet switched and currently use C39 or C40 for an analogue service are now to use that channel for a post-switchover digital service, according to Ofcom's latest documents.
NEW7 and NEW8 are causing problems on a number of transmitter pages where a real mux is temporarily allocated to those frequencies (e.g. Mendip). It's also sowing confusion among users expecting new services to launch at switchover.
I suggest removing NEW7 and NEW8 until we know what is actually going to happen - probably not for another two years unless Mr Hunt tries to push through his local TV proposals sooner (which will cause chaos, but politicians aren't known for their understanding of technical issues).

Mike Dimmick: They are no "erroneous". They will be used for the Local TV services currently proposed by the Culture Secretary and for which there is now at least a single bid, with the services due to start in the next few years.

I live in NR20. Is it anticipated that any pre switchover tests of HD transmission will take place prior to November?

ParishPete: No. There are no free frequencies to launch any new multiplexes, and there's really no time to plan anything at this point - particularly with having built an entirely new transmitting mast at Tacolneston.
Considering that several TV regions have already switched over and launched HD services, there's really nothing to test - particularly since the HD services are taking over BBC One's current analogue frequency.
The switchover programme is complicated, with lots of dependencies between sites. If power is increased or a new service added at one site, it causes additional interference for viewers using another site. Some sites have to have some early retunes in order to free up frequencies for other sites to use, and those sites are farther apart than you might think. The Waltham transmitter near Melton Mowbray will change frequencies twice, for two different multiplexes, at the end of March and mid-April, in order to free up frequencies for The Wrekin transmitter (between Telford and Shrewsbury, about 75 miles away) to start using a week later.
