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?

Your comment please
Please post a question, answer or commentIf you have Freeview reception problems before posting a question your must first do this Freeview reset procedure then see: Freeview reception has changed, Single frequency interference, and Freeview intermittent interference.

If you have no satellite signal, see Sky Digibox says 'No Signal' or 'Technical fault'

If you have other problems, please provide a full (not partial) postcode (or preferably enter it in box at the top right) and indicate where if aerial is on the roof, in the loft or elsewhere.
