I am now pretty certain that all of my problems are related to the heatwave and nothing to do with my .

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 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 . Broadcasters can't prevent it, and adjusting your aerial will make no difference. will only improve when the weather changes."

A Farlow:

There is no difference between any of the transmissions for either BBC or the commercial , they often share the same 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 '' 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 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 and found them on:

746MHz/BBC NEWS HD
754MHz/BBC FOUR HD

rather than the 570 & 586 MHz listed here.

Yes I had noticed it was inaccurate for Com7 and Com8 which are now on the top band, miles away from the band A . Wasn't get any in wet weather 12 miles from the . Having moved to rural I've abandoned and gone for 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 and I am in north . Infuriating.

A Farlow:

In North you should be getting excellent of all . Check what the signal strengths are for all the multiplexes and check that your 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 and cables are fine (no problems getting BBC) and the is 100% but strength barely makes 50%! Things are less problematic now that the heatwave is over when I frequently got no but still ...

A Farlow:

Your strength is too low! It needs to be between 60% and 85% for reliable . That you get BBC1 satisfactorily does not mean there is no problem with the 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 selective problems, such as loss of or por reception of some 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.
