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?

Martyn Smith: Well I suppose its somewhat easier to cope with excessively high signal levels so long as all the multiplexes involved are at about the same levels as each other rather than the frequently experienced problem of reception in some areas where they are not, the balancing act you refer to being the order of the day.
That said though, this type of situation is mostly experienced before final DSO when some commercials are at ludicrously low levels compared to the main PSB muxes, such as applies with the situation at Sudbury.

Crystal Palace has been transmitting digital since November 1998 and analogue only ends this month.
But the relays get the first digital on the day BBC 2 analogue ends, then two weeks later get some more digital TV when BBC1, ITV and Channel 4 analogue ends.
So some have over 11 years to switch but others have to switch on the day BBC2 analogue ends then again two weeks later.
I guess they also need to allow some time for the chap on his bike to get to all the transmitters.

I have 2 Freeview boxes linked to my non-digital tv. After the London digital changeover this week one box(Sony) is performing fine but the other (Panasonic) - which is linked to the recorder is a nightmare. After the Panasonic is turned on or after channel change this freeview box gives a colour picture to start with but then goes to black and white and thereafter fluctuates between colour and black and white. Am in despair as now all that I record is a mix between colour and black and white - so awful. Has anyone else got this problem - can anyone advise me what can be done? Is it likely to be a Reception problem that will rectify once changeover complete on 18th? Do you think there's hope because it shows it can produce colour. Thank you!

Alison: This could be linked to the massively high powered BBC transmitter causing the Panasonic signal overload problems, although as you haven't given your location (pref: post code) this cannot be verified, but purely for a test if you have a set top aerial lying around see if that works.
Another test without using another aerial is to leave the Panasonic sitting on any menu page which if I remember correctly might have a blue background to the printing, then if you see the background colour fluctuating take the aerial out of the box and see if this stabilises the colour, if it does then its overloading.
What model of Panasonic box are you using?

Alison: What was said is taking it that you have the Panasonic coupled to the TV via a scart lead and not by using a coax RF link?

Reception problems
I had perfect digital reception on all channels before the digital switchover.Now when I switch the TV on all the channels appear ,signal strengths between 85%-95% and zero bit error level,but after a short period the signal strength is 0% and the bit error level is 10.I have fitted a new aerial which is giving a good to excellent signal strength. I have also tried a different TV which is ok on all channels but again after a period loses ITV,C4 but is still ok on BBC channels ,Film 4,Really plus a few others.Does anyone have any suggestions?

David J: See here for a posting from someone near to you with a similar problem (loss of ITV1, C4, C5 etc):
Single frequency interference | ukfree.tv - independent free digital TV advice
I wouldn't change aerials as the problem may well right itself on 18th April and therefore any money spent is simply to provide television between now and that date.
Try a set-top aerial if you have one. Or as you have swapped the aerial, try the old aerial at ground level, indoors and maybe outdoors.

carl: You are only 4 miles away from the massively high powered BBC transmitter, so if you have access to a non-amplified type of set top aerial plug that in and carry out another manual tune on Ch23, or should you not be able to obtain one, try a short piece of copper wire of about 8 or 12" or so carefully pushed into the middle part of the aerial socket, because this will provide a suitably reduced level of signal for a test. (Giving an update on results).

carl: That postcode looks like it might be a block of apartments, and therefore you might be using a communal aerial system. If so, check with your landlord or management agent about ensuring that the signal levels to your apartment/flat are correct. See PARAS - Professional Aerial Riggers Against The Sharks for some other thoughts on who to talk to.
