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?

Last Saturday (25th Feb) I could no longer view the independent (non-BBC) Freeview channels. On Sunday 26th service had been restored to all channels. Today I have been unable to receive the following:
ITV1
C4
C5
ITV2
C4+1
More 4
E4
ITV1+1
When I checked the signal strength showing for these channels on my Freeview box, all were low - 4 out of a possible 10. When I can receive these channels they register 6 out of 10. Channels I can receive currently are all registering 6 out of 10.
Channels I am unable to watch deliver pixelated images, and intermittent sound.
I have completely re-set my Freeview box, wiping all existing settings and then rescanned. The problem remains.
I live at the postal code E1W 3RY, and connect via a communal roof aerial in a development of flats. I have not experienced this problem before 25th Feb.
I see that the channels I am having problems with are listed as being on Mux 2 which has a rating of "low". The channels I can receive are on Mux 1 which has a rating of "Maximum."
Can anyone suggest a reason for what appears to be a reduction in the service level available on Mux 2?

Hi,
I also have been encountering an issue with the same channels that David was referring to:
ITV1
C4
C5
ITV2
C4+1
More 4
E4
ITV1+1
Mine appeared to have gone around the same time (only really noticed last Saturday) - might've gone earlier but never noticed.
I have a communal tv Ariel which is on the roof.
Any suggestions? I've rescanned a number of times but still same issue...
I live in NW8 postcode

Jess,
It is evident from your comments and the comments of others that there is something going on, and there is a general state of denial about it. I did a bit of searching and have discovered that the BBC is responsible for investigating problems with the Crystal Palace transmitter. They have an online form you can plough through in order to lodge a formal request for an investigation. You have to go through several questions, essentially answering no to questions such as "is there an obstruction" or could the weather be affecting it. At various stages you will need to answer that no - this has not answered my question. If you persist you will get to a page that tells you there is a problem they can't resolve via the form, and the will ask for specific details of the problem. My suggestion is that if enough people start using this form, it will be difficult for them to maintain the current state of denial.
The link to the form is:
https://faq.external.bbc.…8143
Copy and then paste this link into your browser.
Hope this helps.

David: Pre-switchover, signal levels here from the Hannington were up & down like a fiddlers elbow for months - and now even the unnaffected Muxes are stable. Pre-switchover it was always denied that engineering work was having any effect on digital signals. I suspect ANY site work slightly affected signals in marginal reception areas, taking them below threshold. I suspect much the same for Crystal Palace.
Whether this is true or not; I would hold off enquiries until after the switchover process is completed - because even if you get any relevant answers; they can only refer to a situation which is about to change - or by the time you get them, will have already changed!
I am fairly sure most of the problems people have now will disappear with substantially increased transmitter power.

I live in a comumnal block and can only see a few (very few) of the freeview channel even though I've brought a Freeview HD TV.
I can't even see BBC1, BBC2, ITV, C4 etc - can see them if I use analogue but not DTV. Strange?

Terri: Even although Crystal Palace is still operating on pre-switchover power levels, but with you being located at only 8 miles away from it you "might" be suffering from signal overload problems, albeit I do have my doubts about this, but to test if this possibility can be eliminated as well as getting an idea of the signal level you are receiving, should you have a set top aerial lying around (or have access to one) plug that in followed by carrying out a re-scan and see if that action results in anything more being received, if not though further suggestions can be taken from there.

Since Wednesday 29th Feb 2012 I have had problems with reception at various times of day. All digital channnels bar those in Mux C have suffered extensive or complete picture and sound breakdown for varying periods. My Freeview box shows a general reception strength of about 60% level, but quality of reception varies from 40% for really bad recpetion on most channels to 100% for those in Mux C. I am picking up London in RG4 7LU postcode. Have done all the usual retuning to no avail. Rooftop aerial is OK. Any ideas please?

Thanks to FJC Farrar for your response.
Much as I suspect you are right in what you say, one of my major complaints is the state of denial that there is a problem, and the unaccountability that goes with it. If someone were to admit there is a problem and let us know when it will be resolved, we could all make provision to deal with it. As it is I find myself dealing with a procession of faceless bureaucrats who keep repeating "there are no problems " in the same robot-like manner. It is not good enough.
When I checked Ofcom for a means of chasing this, the only avenue available was directing me to a BBC webform regarding interference problems. In other words "Nothing to do with us Guv." When I reported it to the BBC I received another hollow, form letter response telling me that as the channels affected are not BBC, they can't help. In other words "Nothing to do with us Guv." Not good enough, sorry.
I am bouncing this shambles back to Ofcom, and will continue to pursue it.
