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?

BillNick: The window is big so it's not critical.
Signal strength scales vary by receiver, but say you get a good signal with it set to 75% strength on the channels you have, then try manually adding the missing ones.
Once you have each one tuned, then don't rescan if you find one poor quality as the issue must lie elsewhere.
DC power-pass is required where an amplifier (mast-head amp) is being used at the aerial where the power supply is fitted behind the TV set. The DC voltage to supply the amp is carried up the aerial cable and thus if the attenuator were fitted inbetween the two, it would need to be the power-pass variety.

Until about a week and a half ago, my Freeview signal in South Harrow, North-West London was 100% on all channels - without the need for amplification. Since then I have experienced mild pixellation on some ITV channels, followed by total loss of all ITV channels, leaving only highly pixellated Freeview "Lite" i.e. BBC only accompanied by audio loss. Done the usual checks on cabling. connections and "Factory resets" on TV set without improvement.No known sources of signal interference or line-of-sight obstructions. So suspect engineering work is ongoing.
This is really to much - to lose all programming over Xmas and without notice and for the second time in the year.

Nick R: There is no engineering work going on. Even when there is, it is stopped for Xmas.
As you mentioned "100%" you should look at Freeview signals: too much of a good thing is bad for you | ukfree.tv - 10 years of independent, free digital TV advice .

Hello
I live in Borough/London Bridge. A few days ago we suddenly lost the channels in Multiplex 2 and A (ITV C4 E4 etc). I have tried to rescan and reset the freview but now it won't even find the channels. I have spoken to neighbours and they are having a similar issue.

Alex: Your postcode resolves to a block of flats which makes me think that there might be a communal aerial system. Thus, you and your neighbours who have the same issue have something in common: the aerial system.
This tends to point to some issue with it so this will need reporting to whoever is responsible for it (e.g. the landlord).
Try a manual tune on UHF channel 26 for Mux 2. Having brought up the manual tune screen and entered/selected 26, prior to pressing the button to scan (might be "OK"), observe whether there is any indication of strength and quality.

Lost BBC from Crystal Palace.
I have recently lost BBC channels on channel 23 from Crystal Palace. HD on ch 30 also weak however ITV channels from the same transmitter on ch 26 are excellent so the aerial system is clearly working.
I have two aerials pointing at Hannington and Crystal Palace diplexed then fed into an old Labgear distribution amp together with an FM aerial signal. Hannington signals are fine. I want the London BBC channels for local news.
Any idea why only the BBC signals are affected? There aren't any engineering works listed so I am baffled. Could it be the distribution amp?

JB38* If I can get Freeview in Ash Vale, does this mean I can get the HD signals as well. I am thinking of upgrading my tv to one with a Freeview HD tuner. Thanks, martyh

martyh: On having a look at the reception predictions for your area it would appear that where you reside could be problematic area for reception, as reception from Hannington (@ 22 miles) on all muxes (except presently HD) is indicated as being variable on a permanent basis, Crystal Palace (@ 30 miles) being reasonable on its PSB muxes but poor on everything else.
That said, reception predictors cannot be taken as being anywhere near to 100% accurate in what they indicate is possible (or not) and if you can presently receive the two Freeview PSB muxes (BBC & ITV) reasonably OK then the chances are good that you will likewise receive the same on HD.
Be careful when choosing a TV though just in case it does not have a DVB-T2 tuner as numerous people have been caught out by the way that these devices are advertised, any doubts whatsoever just post the model number on this site and it can possibly be checked out.

My post code is E15 . Recently I have lost a couple of channels namely 17,48,82 and 11. The BBC channels are also playing up. I can get perfect reception in the evenings and then absolutely nothing in the mornings. It keeps saying 'no video input' I have tried retuning many many times to no avail.
Please help.
Thanks (E15 Re)

Jb38, thanks. At the mo I am considering the Panasonic Smart Viera range of tv's, such as the E5 series/ET5 series, although after a chat with my local dealer, I'll hang on a bit as Panasonic are bringing out uprated improved verions of current models in about a month. All boast Freeview HD capability. I had a chance to view 3 different tv's in store with megahertz ratings ranging from 150 up to 1600, from standard Freeview broadcasts and was pretty amazed at how sharp even the 150 mhz model was. Also, I wasn't aware of the refresh rate being so important in definition terms. If you go back over my posts I'm sure you'll remember all that trouble I had with my Philips CRT and the new signal, where I bought a dongle in the end to get the 2k channels. I get 105 channels (inc radio, BBC, ITV etc) right now (Ash Vale), so it sounds quite promising from what you said. Many thanks, martyh
