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.

here's a story that's about the Digital switchover help scheme.
My Aunt who is 86 lives in the SE9 area of London a very strong signal area and who has been using Freeview for a number of years using an internal aerial which 99.9% of the time works fine. She has a PVR connected to her TV enabling her to record one channel whilst viewing another, After I told her about the £40 help scheme she applied and an aerial contracted was sent out to check the system and give her a STB for her 2nd set in her bedroom.
As I live some 40 miles from her I was unable to be there when he called, I spoke to her on the phone that evening to ask how it went she told me that the man was there for 20 mins had check the installation and connected the free STB to the TV. This is when alarm bells started to ring!
I saw a copy of the check list tick sheet he had completed, this is what it show. Aerial face plate fitted, YES, Benchmark cables use, YES, Aerial checked, YES. The answer to all these questions is NO in her installation. What the man had done was remove her PVR leave a basic Freeview box under the TV and charge £40 for a box that I could have got from Tesco for £20. I made a complaint to the scheme and another appointment was made that I could attend, the whole idea was to get her an basic outside aerial which the scheme provides not for some aerial guy to make a quick £40 doing little or nothing!

David, as I have said before, it seems there is a common thread to a number of recent posts regarding loss of signal level from Crystal Palace? I now have only Muxes 1, B, and C, with zero signal levels on the others, having enjoyed 104 channels on Freeview before. Nothing has changed at my end, so it must be either the Tx or the transmission path. I have suggested as others have that the engineering works are affecting the output, but as you have seen before - the answer is apparently interference. I can only agree with you that denying something is being affected at the transmitter is not helpful. Ironically I now have to use the analogue rx to get an ITV/Ch4/5 signal. Progress!

Graham,
Thanks very much for your comments. I know exactly what you mean. If people were given honest information, they could at least understand what was happening and why (and how long it would last). Because this "process" is being administered by people who ram their heads into buckets of sand whenever a complaint is made, we will have to enlist other help.
As a matter of formality (not because I expect any positive outcome) I am writing to Ofcom pointing out their lack of any useful assistance via their web site, and asking them to give me a means of escalating this matter. Their normal response is to say "ring us on our helpline", but I won't be doing that as it gives me nothing in writing. So far, Ofcom have been as useful as an ashtray on a motorbike. No change there.
I have also written (as another formality) to the Digital UK website at Digital UK - Home (the one with the vapid, smiley robot). In essence I have made the same comments as I did to Ofcom, but truncated as they restrict users to 500 characters.
Of more potential use, I have logged a case with BBC Watchdog, as there are a lot of people who have been paying out for new equipment and engineer visits needlessly because of the culture of denial during switch-over. This is a rip-off any anyone's language (see especially Tim's comments further up the page about his aunt's experience). Obviously if Watchdog start getting a lot of complaints about the problems we have been having, they are in a much better position to do something about it.
For anyone interested in taking it further, the Watchdog URL is:
BBC - Watchdog - - Got a story
or, if you prefer, you can email your complaint to them at:
watchdog@bbc.co.uk.
or write to them at:
Watchdog, MC4 C5, Media Centre, Wood Lane, London W12 7TQ.
Hope this helps.
