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?

Thank you Dave Lindsay. I will probably have a go tomorrow (doubt I will have time tonight). This is providing I can find the signal strength screen!
I hope it is easy to change transmitters if necessary.

NICK ADSL UK: Regarding Freeview reception, I have always been of the opinion (and have frequently voiced it) that anyone of a critical nature who demands a virtually trouble free service for 99.9% of the time should always consider Freesat as their No1 choice for reception, as although Freeview reception certainly scores for its sheer versatility as far as being used to feed a number of TV or boxes in the same property is concerned without any great hassle being involved, this when compared to the situation with satellite reception where individual feeds from a dish to each receiver is required, but this latter inconvenience is a small price to pay for super reliable reception, with myself using a combination of Freesat / Freeview / and Sky's free to view services, albeit that roughly 80% of the live viewing made via satellite.
Another thing I have always voiced my opinion about is, that once the whole country is switched over to digital TV there is very likely to be far more complaints of a continuing nature with terrestrial digital TV reception than ever existed with analogue, as even in relatively perfect installations (which most aren't) trouble can be experienced for all sorts of reasons totally out with the control of the viewer, (e.g: inversion effect etc) but unlike when this happened with analogue where the viewer had to put up with wavy lines or ghost images etc in the background of their picture at least they could still see it, and so were more likely to accept the problem and not immediately kick up about it, whereas with digital reception it results in a range of the most irritating symptoms like constant picture glitches accompanied by squeals on the audio, that is "if" any picture was there to see in the first place!
There are lots of areas in the UK that will never at any time have good reception, and the further removed a viewer is from the ideal line-of-site position then the more vulnerable their reception will be to being interfered with, and this is something that will never change, that being why digital is perfect for satellite as there is the absolute minimum of external factors that can interfere with it, the main one being a really heavy thundery type downpour, the use of a slightly larger dish even minimising this from happening.
I could go on but wont as I already feel that my postings are lengthy enough, but some things have to be said.

You make good sense and are clearly a professional JB. As for myself i dont get taken seriously despite in the beginning i got the likes of the pioneer chairman involved Mr Sato in the making of the first pioneer on digital box as the original Phillips box like what many people see today with picture freeze and by getting him involved along with a team at Sony we managed to put together 2 boxes that were first class and glitch free
I still have the original Sony at home they were good days all i was to the project was just a unpaid beta tester just like today as a unpaid Microsoft mvp in helping others across the world

Dave Lindsay: I have checked my channels this morning and BBC1 HD is coming through on Channel 30. It has S (signal?) of 17% and Q (quality?) of variable 44 - 47%
I also checked BBC1 /2 on ch 23 S=77% Q=100%
ITV1 /Ch.4 /5 ch 26 S=51% Q=100%
BBC News / Parliament ch 23 S=77% Q=100% Sky News ch 22 S=77% Q=100%
Would it be worth trying to change the channels for the HD services, and if so how?! It is a Sony svr-hdt500-freeview HD recorder.
Thanks.

Big Mart: Perhaps one of the pros could step in as I'm not sure what else to suggest...except for wondering if it could be signal overload (with the effects showing on some channels more than on others):

Hi JB38
Thanks for all your input I have now purchased a Luxor 16" LED HD ready? whatever that means,cheapest one I could find and it works OK.
I will still try to find the problem with the other one when I've more time, just for my peace of mind.
I see a nieghbour has had a huge aerial fitted it looks like something off the Space Station must ask him if it works.
Is there an email address where people can register their complaints? Is anyone correalating the problems.
I don't see why people should have to have a satellite dish fitted as suggested by by yourself,perhaps the powers that be could supply and fit one for them ,if they had no problems before.
Personally I can live without hundreds of channels of "celebrity programs,no talent shows,and endless repeats some several times in the same week. As there are only enough programmes for half a dozen channels why do we need the other hundred? and Sky why?
Yours Dave (grumpy old man)

Dave Lindsay: Thanks for trying to help. I live 18 miles from Crystal Palace (according to Google Maps) - would I get overload from that distance?
Obviously I have not checked out 118 channels for reception!

SDN are transmitting using QAM_64, but stating in the NIT that they're using QPSK :-( Don't know if this is country-wide, or just on Crystal Palace.

Big Mart: I think it might be possible to have overload at that distance. This is more likely the bigger (higher the gain) of the aerial as by definition they pull in more signal.
There is no need to check out 118 channels!
They are transmitted in groups known as multiplexes; see "After switchover configuration" here:
Freeview multiplexes | ukfree.tv - independent free digital TV advice
There are six multiplexes (including one for HD) so you only need to look at one service from each. I would focus on the first from each: BBC One, ITV1, BBC One HD, ITV3, Pick TV and Yesterday.

Hi. I've been lurking on this site for weeks.
We live on the top floor of a block of flats near N5 2NL. We used to have a booster that served as a splitter to two Bush B320DTR boxes, but have now replaced that with a three way splitter as we were suffering bad reception since the end of March.
Now since the 18th we've had problems with a few muxes dropping out altogether on C22, C23, and C28. With retuning, sometimes the channels won't even appear in the list. One retune put the BBC channels on the channel 800 range, another retune put the COM5 mux channels there.
At first, we had gotten all the channels, but the reception seems so sensitive now that entire bands of channels are unwatchable at varying times of the day and is now totally unreliable.
Signal levels are around 70%, but quality is nil, with a black screen as a result. In fact, when trying a manual scan, the missing mux bands initially read as 'very good' before instantly reading as 'none'.
Do we buy an attenuator or an indoor aerial? Our building shares an aerial, so there's no way we can adjust it ourselves. This is very frustrating.
