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?

The note says that Crystal Palace may have interruption. I am missing itv, C4, C5, itv2, pick, Dave, c4+1, more4, film4, really, e4, e4+1, movie mix, itv+1, and more, but bbc etc are all perfectly ok.
Is there an issue with one of the multiplexes?
I had same issue one night last week (Friday) but ok over the weekend, I think!
Retuning didn't solve the issue, channels listed were then missing completely.
I live in KT24 5DR, aerial is external on the chimney. And I have a boost amplifier.

Can anyone tell me why I can't get the new HD Mux Com7? My postcode is RM3 0BL and I get all channels clear as a bell. Is it on now or does it switch off now and again? I know theres no rush but I just like to know is it me or them?

My post code is London E4. I receive my (good) signal from crystal palace. Manual scan of Com7 (UHF33) is finding duplicate HD channel labels for BB1,2,ITV1,CH4,BBC3,CBBC and RB303.
These channels have no video or audio stream. It seems my Akura STB model AVX665 is not getting the correct SID on com 7 as the only label I should get is Al Jazeera england HD.

Hi,
My BT vision box will not receive any freeview channels. The BT helpline is telling me that is because of engineering works at Crystal Palace.
Has there really been engineering works at Crystal palace for the past 2 months that i have had this problem?

Richard: Since your not too far from Crystal Palace, and that transmitter is fine, look at your system. Check aerial lead, and cables up the aerial itself, because thats probably where the problem is.

I have a loft aerial and had good reception from Crystal Palace for all channels after the switchover - no weather interference or any interuptions for the whole of 2012. Since the start of this year (2013) the signal had gradually been getting worse and I had to start using a booster for some channels. Since the storm on 28th October I lost all channels on ArqA and have since lost all BBC channels too. I have tried blanking all channels and retuning more than once and each time the number of channels detected decreases! There is no reports of engineering works or other problems so I can't work out what's going on. I live in ME7 just down the road (north) from Medway Maritme Hospital.

LouiseB: By resetting you are simply deleting what is stored and then carrying out a scan of what is available. As the channels ceased to be available to you before resetting then how can the act of resetting ever make them available?? The answer is that resetting will only result in loss of the channels from the receiver, or them coming back, in which case they would have come back anyway because the receiver will give you the best picture it can for the signal being fed into it.
I wonder why you aren't using Bluebell Hill, which would also give you BBC South East and ITV Merdian, rather than their London variants from Crystal Palace. The only thing I can think, other than maybe you prefer London news, is that the hospital is in the way.
I suggest that you don't have line-of-sight to Crystal Palace. I can't say with absolute certainty, but I think the brow over which you are receiving is somewhere around Shorne Wood Country Park. Anything on that brow that might change, such as trees, and anything that is in or near the line-of-sight that changes could affect your reception.
I then looked at the satellite image your area, as published by Google. To the north of the hospital, in the direction of Crystal Palace is a field which has outlines of roads. It looks as if there is a development which has appeared since the photograph was taken. If this is the case, and buildings have gone up this year then there must surely be suspicion that this is the cause for anyone experiencing degrading TV reception from Crystal Palace to the area's east.

Dave: Thanks for the reply. I had only been having intermittent problems with ArqA and ArqB for the last few months, which could be explained by the development (which is a new/rebuilt school that was finished in August). The last few weeks had been ridiculous though - ArqA and ArqB got much worse at times, to the point that a booster made no difference. And then since the storm on 28th October all channels on ArqA, ArqB and BBCA went completely blank and reported weak or no signal. I decided to retune to see if it would help (bit of an old analogue mentality, I know). I was surprised to find that the transmitter didn't have storm damage as that's the only explanation I could think of.
I have also posted on the Bluebell Hill transmitter as I turned my loft aerial the other day to see if it was any better from there (last time I tried was before the area switched over), but that is proving just as problematic with little or no signal on ArqA, no signal what so ever from ArqB and since this afternoon (weather has got windy) serious break up on BBCA & SDN, incidentally channels received via D3+4 are all fine.
Just for reference; in the analogue era we used to get too much interfence from the hospital to receive much from Bluebell Hill, I grew up watching Thames and LWT (same house) because of it.

LouiseB: Reading through your posts, something suddenly occurs. Have yo actually checked the quality of your connection to the aerial?
You've suddenly lost all channels (no matter which transmitter), so that might signify a break or waterlogging in the cable. The decreasing amount of signal quality could also be down to the same problem - a gradually degrading coax, etc, until the storm finally killed it.
A frayed coax, corroded box or aerial can all cause such problems.
