John: It is an allocation for Local TV, services may or may not start at switchover. See the Local television | ukfree.tv - independent free digital TV advice section.

Hi,
I am running a Philips HDT8520 PVR, which until 12th April 2011 was perfectly able to receive all the available freeview HD channels. From this date, all HD channels were showing as 'signal lost'.
I have re-tuned and unplugged the aerial several times and the box no longer finds any HD channels. The problem is the same for my TV which has a built in freeview HD receiver.
Is this a symptom of the switchover process? I have a communal aerial that serves a block of flats and as far as I am aware it has not been altered or tampered with. My postcode is SW15 2PX which shows a good signal strength according to the coverage checker service.
Any suggestions as to what might be going on would be much appreciated.
Cheers,
Aaron

Aaron: There is no "switchover process" in London until next year. I would look at Single frequency interference | ukfree.tv - independent free digital TV advice .

Briantist - Thanks for your advice. I have nothing else plugged into the PVR/TV and the situation hasn't changed to trigger the loss of the channels.
Could it be that somebody else in the building is affecting the signal/causing the interference?
Cheers,
Aaron

I am located on the fringes of three transmitters: Sandy, Oxford, Crystal Palace. I have two good chimney mounted arrays aimed at Crystal Palace and Oxford. We prefer the London output, so Oxford was the second choice and Sandy ignored due to the (analogue) band clash with CP and also a very weak signal due to intervening high ground. My Toshiba TVs will not tune all the Freeview channels from all transmitters, but we have so far been able to tune ITV1 from both. Today's retune has opted for Sandy rather than Oxford (which has disappeared) even though the signal is very weak, and we get a choice of BBC1 regions instead of ITV1 regions. Is there any way I can impose my choice on this mess ?

Hello , I have a bit of a technical question I am curious about if anyone can help ?
I ran the trade digitaluk post code checker for my address just to see what it predicated. I am only 13km from Crystal Palace but it gives a really low percentage for satisfactory reception on a couple of channels, D32 at 53pc and D29 at 80pc. It stays at these percentages all the way until switchover.
Of course the signal is fine but I am just really puzzled as to what would cause such low figures on these 2 channels. The terrain is pretty flat near me and my fathers house 2km further away from CP gives 99pc on these 2 channels.
The predicter does show reasonable signals from the north west (Sandy) and South East (Bluebell Hill, Dover) and yes there is a slight drop off in the land both ways but I can not find any mast that would cause this percentage drop operating on CH29 or CH32. Maybe D29 is Waltham on the same channel but I doubt it and anyway D32 is the real mystery.
Just curious really, I appreciate no one may have an answer !
