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?

I am now pretty certain that all of my problems are related to the heatwave and nothing to do with my aerial.
Possible causes of interference - at800
"High pressure, which brings fine weather, allows signals to reach areas they wouldn't normally reach. Under normal circumstances, the signals from each television transmitter can only be received by those homes that have aerials with a direct line-of-sight to the transmitter. However on warm summer days, hot air can get trapped under colder air high up creating a layer which acts like a mirror for television signals, reflecting them back towards Earth. This can cause signals from different transmitters to overlap. Unfortunately, there is no solution to this kind of interference. Broadcasters can't prevent it, and adjusting your aerial will make no difference. Reception will only improve when the weather changes."
Tsk! Men on the moon forty years ago and still .....

What is really odd is that when the commercials are shown reception is at least better if not perfect!!!!!
It's a mystery ...

There is no difference between any of the transmissions for either BBC or the commercial channels, they often share the same multiplex in some cases too! Similarly there is no change when the commercials are being shown, though some suggest the sound levels are increased but that is denied by the broadcasters concerned.
The hot weather patterns we have been experiencing for the last several weeks always gives rise to 'interference' due to natural atmospheric conditions causing signals to travel much further than is usual. There is nothing anyone can do and it has happened to TV transmissions ever since we started using UHF back in the 1960's.

Thanks for the great site. However, is the Crystal Palace Transmitter page up to date? I could not manually tune an old device to get BBC News HD or BBC Four HD using the details here. Then I checked my TV's signal diagnostics and found them on:
746MHz/BBC NEWS HD
754MHz/BBC FOUR HD
rather than the 570 & 586 MHz listed here.

The owner of this site has not updated it for several months, we do not know why.
For accurate information on which channels are being used by which transmitter, please go to the Digital UK Coverage Checker at Digital UK - Coverage checker and put in the required information. That will then show which transmitters are availab le in your area and which channels it is using.
If you wish to have a detailed listing of which programmes are available go to http://www.digitaluk.co.u…ngs.

Yes I had noticed it was inaccurate for Com7 and Com8 which are now on the top band, miles away from the band A aerial. Wasn't get any signal in wet weather 12 miles from the transmitter. Having moved to rural Wales I've abandoned Freeview and gone for Freesat plus the delights of Wimax rural broadband since BT broadband hasn't arrived in the villages.

I have no idea what this means technically, but do know that when the weather is unusual I cannot get commercial channels and I am in north London. Infuriating.

In North London you should be getting excellent reception of all channels. Check what the signal strengths are for all the multiplexes and check that your aerial cables are in good condition, do not have water ingress and that all the connections are in good order and free from corrosion/oxidation.
If you provide a full post code we will be able to see what the predicted reception at you location is likely to be.

As I have posted before the aerial and cables are fine (no problems getting BBC) and the quality is 100% but strength barely makes 50%! Things are less problematic now that the heatwave is over when I frequently got no reception but still ...

Your signal strength is too low! It needs to be between 60% and 85% for reliable reception. That you get BBC1 satisfactorily does not mean there is no problem with the aerial system. It is well known in the technical side of the trade that corrosion/oxidation of the contacts of any plug or socket in the system can cause frequency selective problems, such as loss of or por reception of some channels whilst others are fine. So please check all your aerial connections. Please could you also give your full post code so that we contributors can see what the expected recpetion conditions are like at your location.
