The worst thing to do was a retune! It will never bring back the channels under the conditions you describe. You will now need to do a manual tune using the actual channel numbers being used by the transmitter. To find those, put your post code into the Digital UK Coverage Checker at Digital UK - Coverage checker Then use the channel number listed to retune your TV set to each of the multiplexes.

There can be a number of reason for the loss of signals, the main one at present being the warm weather. That causes inteference by signals fro other transmitters travelling further than usual, which the TV can't cope with and you loose the channels. The other posibility is a bad connection in your aerial feed. So check all the connections you can safely reach, starting at the back of the TV and working as far up to the aerial as you can get.

Ok, thanks. We have had on screen announcements to retune tomorrow, due to alterations to signalling. I will have to find out if I get the London channels back.

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 ...

A Farlow:

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:


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…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.

A Farlow:

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.
