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?

Just as a status report from CM3 7AH, between Chelmsford & Southend. All digital channels present on Techwood Freeview+ & TopUp TV+ boxes.

Graham: Except for the higher areas towards Bagshot; Reception in most of Camberley is now much better from the Hannington transmitter even though MUXs ARQA & ARQB remain power-restricted until 18th April. Of course, if you only have an aerial pointing towards London, it is worth waiting for switchover completion at Crystal Palace to see if signals become adequate on all MUXs.

Graham: The Digital UK predictor does not show signal strengths. It shows the percentage of locations across the grid square that are expected to have sufficient signal strength, compared to interference from other transmitters, for 99% of the time, and for 50% of the time. The figures really show the relative difficulty of siting an aerial at your location.

In contrast, your box does not subtract the strength of the interference from the strength of the wanted signal and simply reports the total power received on the selected frequency. It is possible for equipment to reconstruct the desired signal internally, basically re-encoding after decoding, and subtract it from what was received, but this is typically only done by specialist measuring equipment. (Installers *should* use equipment that does this, in order to find the best location for the aerial).

If the 99%-time figure is over 70%, the square is considered 'covered', shown as 'good' (green) and the service will be protected against interference from any new services (e.g. 'white space' broadband, local TV services at another transmitter). If the 99%-time figure is below 70% but the 50%-time figure is above, it will be shown as 'variable' (orange). If both are below 70% but 50%-time is still over 50%, it will show as 'poor' (red). If below 50%, the square will be blank.

For you, your best bet is probably Midhurst, although it thinks your aerial is most likely pointing to Hannington. Commercial muxes from Crystal Palace will be poor after 18 April, despite the power increase, because they will use the same channels as the corresponding transmissions from Rowridge. Rowridge may be too weak to use, but it's certainly strong enough to cause you problems!

All I want to know is the planned works for Crystal Palace transmitter AHEAD of time.
I was waiting to watch BBC1 at 12.15am last night and zip.. gone.. black, lost ITV 1 at the same time then Channel 4. Was left in insomnia hell with BBC 2 reporting on the US elections Super Tuesday and channel 5 Super Casino arghh. This has been happening over the last month. I only have analogue. How can I find out for tv tonight/early morning?
I know this is a techi site but it is all I can find.

Mike Dimmick; Despite what the predictors suggest, I do not know anywhere in Camberley that can even detect that the Midhurst transmitter even exists - probably because the intervening topography. Since the same applies to the Rowridge transmitter, Crystal Palace will probably be OK after switchover is completed. However, Hannington is fine right now even with occasional glitches from two temporarily low-power MUXs.

Mim, I would strongly suggest you get a freeview set top box starting around £ 20 as Crystal Palace will start to stop analogue broadcasting in the next 4 weeks. At the moment they are testing the new equipment and this loss of analogue channels will happen again in the small hours. Check the top of this page for crystal palace transmitter analogue shutdown schedule.

Thanks for all the comments.
FJC, I live on the Crystal Palace side of a ridge at the Bagshot end of Camberley at 100m with 20m above me protecting me from Hannington.
Mike, the predictor under the "Full Details tab" claims to provide receiver signal strengths, see Find out how to receive Freeview and Freeview HD | - independent free digital TV advice The predictor also claims that my best solution is Crystal Palace today and also shows the best signal strengths after switchover.

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.
