The symbol shows the location of the Crystal Palace (Greater London, England) transmitter which serves 4,490,000 homes. The bright green areas shown where the signal from this transmitter is strong, dark green areas are poorer signals. Those parts shown in yellow may have interference on the same frequency from other masts.

Are there any planned engineering works or unexpected transmitter faults on the Crystal Palace (Greater London, England) mast?

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 !
Brian

Hi,
Can you help/advise please?
All freeview channels have beem missing from our two TV's since sometime on 13/04.

Aerial is on the roof.

I've tried the various resets and no better.

The Sony Freeview box indicates Average signal strength Poor signal quality.

Digital UK says we'll be on Crystal Palace and looking at the aerial position that looks correct to me.

Analogue signal is available but poor but then it always has been, or certainly for many years.

Any advice gratefully received.

Thanks

Richard

Thanks Brian(tist) !

I think I managed to figure it out for myself in the end. I would guess CP temporary digital aerials have a null to the east on D29 and D32 to prevent interference with the analogue(now closed) mast at Goes in Zeeland (the reason why CP analogue Channel 4 uses E30 not E29).

In addition I would guess that D32 is further reduced to prevent interference with the Faversham analogue relay.

The lay of the land near my house means that most people need roof aerials for CP (which is not the norm for most places close by) . Therefore I would guess as soon as the predictor believes there is less than a 100pc signal east of the mast it reduces the potential signal readings big time on D29 and D32.

Pity there does not seem to be anything published showing the radiation patterns. It must be a closely guarded secret !

cheers Brian, what an odd mix of transmitters. Bressay, Aberdare !
Nothing on CP , state secret as you say.
It took me ages to figure out my question. It was obvious really...

brian: I have more post-switchover ones, but only for relays. The main transmitter patterns are all redacted.

I will, at some point, include these on the site. When I have time.

Your comment please
Please post a question, answer or commentIf you have Freeview reception problems before posting a question your must first do this Freeview reset procedure then see: Freeview reception has changed, Single frequency interference, and Freeview intermittent interference.

If you have no satellite signal, see Sky Digibox says 'No Signal' or 'Technical fault'

If you have other problems, please provide a full (not partial) postcode (or preferably enter it in box at the top right) and indicate where if aerial is on the roof, in the loft or elsewhere.
