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?

Thanks to David and FJC Farrar for some useful input. As an update to my situation issues have continued. It starts to look as if its mainly happening during morning TV, then clears for the afternoon and early/ peak evening, then starts again after about midnight or 1 a.m. As an ex IT systems person this looks suspiciously like scheduled work to minimise the disruption to (presumed) main viewers. Not much use if you are a shift worker, or (like me) record stuff on BBC3 and 4 in the early hours. I agree with David that we should raise this wherever possible. I have written to Watchdog, BBC reception and Digital UK. The BBC have trotted out the usual "help" and I have contacted Digital UK on their advice. I have been given a case number by the Beeb at least and will follow up with them depending on the DigitalUK response. I am not expecting much comeback, but I feel I should follow all avenues before escalating further. The irony is that all the engineering reports talk of weaker signals on analogue BBC 1 and 2, but mine (on my old Panasonic CRT TV) have never seemed better!

LesG: What you describe is also typical of the effects of the RF reflective sky-layers, which tend to move up & down around dusk & dawn, affecting "skip-distances". If you are already in an area with lowish signals, you will either get drop-out periods twice in 24hrs - or just as likely only have good periods only twice a day. Again, when power is increased (and it is going to increase signal levels a lot!) at final switchover, most such effects will disappear. Be patient.
Incidentally, why Crystal Palace when Reading is smack in the middle of Hannington's coverage?

As a rider relating to the lack of information etc. leading to people buying new equipment:
Since if reception fails anywhere, there seems to be no way of directly reporting this; I fail to see how DUK can state Transmitters are working normally. Surely they can only report that as far as they are aware nothing has been done which has changed reception.
The clue is "as far as they are aware" since there seems no possible way in which they could be aware if reception had changed. Maybe if they had stated that DTV reception COULD be affected during the lead-up to final switchover we would have been satisfied?

Bishop's Stortford
Hi, am going to have to be a bit vague with my question, but would appreciate any help you could give me.
My daughter has moved to Bishops Stortford, taking a Logik Digital TV, (previously used in Worcester). She tried to set it up yesterday but could get nothing, just messages saying how poor the signals were. She has tried resetting the TV and tuned the TV several times, with no result. I notice from previous posts that there seem to have been a few problems in the South East, so was wondering if there are still problems with the signal, which will be rectified at the time of the changeover, or is it more likely to be due to an inadequate or faulty aerial? She is currently having to use the analogue signal, which is quite poor. Please help!

Pat Brock: In general terms, the digital signals for Public Service Broadcasters (PSBs) after switchover will match that of the current analogue.
Transmitters serving the Worcester area have switched fully to digital whereas those in Bishop's Stortford have not and are therefore on low pre-switchover power or, in the case of the Bishop's Stortford relay transmitter, does not carry digital at all yet.
One thing is for sure and that is if your daughter's aerial is directed at the Bishop's Stortford relay transmitter which is on Rayners Road Industrial Estate (the aerial will be vertical), then she will not be able to receive (certainly reliable) Freeview before switchover and after switchover will only receive PSB channels.
If analogue reception is poor, then this could be because the TV has tuned to the wrong transmitter. That is, if the aerial points at Bishop's Stortford it could be tuned to Crystal Palace (or another transmitter) or vice versa.
If your daughter's aerial is on Crystal Palace, then hopefully it will be OK. I would suggest that it is best to wait until April because the current aerial may work fine come switchover.

andy: From 18th April Crystal Palace will be a full Freeview transmitter. There will be no services on low power to protect against interference from other areas (that have not switched over yet) as has happened with Sudbury.

I'm genuinely indebted once more (as always) for the technical explanations advanced by FJC Farrar. I have no doubt they are all sound, and you appear very well informed. My question remains, why since 25th Feb (or thereabouts) have people scattered all over London been losing their Freeview channels if nobody had any hint that this might happen? (mine are down again this evening). The switchover process has been under way for some time throughout the UK, and unless each team that carries it out treats it like a state secret, there will be a body of information borne of experience, that shows them to expect that some people will be affected adversely during the process.
A while ago Digital UK sent out a leaflet to my address titled "Is your flat ready for the TV switchover in April 2012?" I have every reason to believe this is a national campaign, not something they have just favoured me alone with. On it they listed two points to check. An extra line of text as point three could have warned people that they might experience erratic reception as they approach switchover, so don't rush out and buy new equipment until the process is complete. It isn't quantum physics to do this, but there appears to be an attitude prevalent that this is "nothing to do with us, Guv". Oh, and if you happen to buy new equipment needlessly because you lose Freeview access and don't realise it is temporary, hard luck.
Science marches on.
