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?

This may be a bit off-topic, but do you know if there is anything strange about program 10 (ITV3) in the MuxA (or SDN) transmission ? One of my TVs (Tosh 19W330DB) adds all the MuxA programs to its list, but shows the previous program when 10 is selected. Two other TV sets work OK.

I suggest you do a full reset first. (50.9889,-1.4989)

Thank you Matt, that fixed it. So the full retune which "removes all existing programs" is not exactly true. The full reset has had some undesirable effects as well, for instance I cannot now change programs 1 and 3 to London by manually re-tuning channels 22 and 25 (I have two aerials - CP and OX) which previously was possible.

I have a Digital Stream DHR8203U, I was able to receive HD freeview at home in the DA8 1 post code up until a week ago.
are there issues or is it my freeview box? I have tried retuning in multiple times, resetting to factory and just get SD freeview each time now :(
thanks

I am currently in Reading picking up around 90 services from Crystal Palace, excellent picture quality. I'm using my computer with Windows Medis Centre through a DTV media card, for some reason my TV guide is showing Channel 5 as "no information availble" I can watch the channel and its a good picture but despite following Microsofts fixes its still the same, so I have to ask if this is a CH5 related issue or does anyone have any ideas?

Stuart: If you select the channel name in the Windows Media Center EPG, press the "i" button on the remote, you can select the "add channel listing to channel" option that will allow you to associate the correct listing to the channel.

John: I would have a look at Single frequency interference | ukfree.tv - independent free digital TV advice as there is no reason you should have problems with Freeview HD, assuming your are using a rooftop aerial.

I have been receiving freeview from Crystal Palace mast with no problems for a few years now. Over the weekend 15/10 and 16/10 all channels associated with multiplex 2 (ITV, ITV2, E4 etc) are all suffering from intermittent interference. I have four different TVs on different types of digibox or inbuilt tuners, I am happy that they are all fine and the aerial is ok and still on the roof! Looking at the site it seems there may be work going on which could be causing the problem, is anyone able to confirm?

MarkR I live in Reading and I sometimes find after doing an automatic retune that my Humax PVR sometimes decides to tune to the Hannington transmitter. The communal aerial in my apartment block is pointing towards Crystal Palace so the Hannington signal is always poor. Yesterday morning I got up early to watch the Formula 1 and lost all of the HD channels. I did an automatic rescan and found that the ITV was tuned to Hannington. I did a manual retune of channel 22 (found out from this page) so I could get decent picture for ITV. It is worth checking the channel numbers of the ITV MUX and other channels and comparing them with the channel numbers on this page because I would imagine that you also may be able to get Hannington in Bracknell. I believe that the atmospheric conditions were conducive to co-channel interference yesterday. I retuned again this evening and have the HD channels back again now.

MarkR, stevea: I had to resort to watching the F1 on my laptop as both analogue and digital were poor. I think it was down to atmospherics - it was quite foggy on Sunday morning - rather than any work on the transmitter. (I wouldn't want to be up a mast at 6am on a Sunday, would you?)
