The aerial is in the loft and we had good reception on all channels until quite recently. We now have several channels with either no signal or break up intermittantly. I have retuned from scratch without any difference being made there are no new electronic items in the home. All the channels are on Black Hill COM4 they are channels 10, 20, 66 etc.

Graham Jones: Your just 31km from the transmitter (Black Hill) - so its unlikely to be a problem with you getting a signal.

Check the signal strength - is it too high or too low. A month ago you had a retune event, and it could be that signal levels have risen at that point, and now its a bit high on some muxes, hence the 'no signal', etc.

But if you signal levels are low, then its certainly your system - so check for frayed cables, loose connections, etc.

Paul Denning:

There is no fault reported at the Bristol Ilchester Crescent transmitter. Check your aerial cables and connections. Also check you signal strength, if it is above 85% then search this website for 'too much of a good thing' as too high signal will cause your problem.

paul denning: You very close to the transmitter, and MikeP rightly suggested too high a signal. Just because the signal has stopped breaking up does not mean its cured - it could just be that high pressure etc has pushed signal strength above the point where the tuner is happy. But its probably going to happen again.

MikeB: yes I understand what high pressure does to tv signals - but would expect it would happen to more than one mux at a time

Paul Denning:

It is not just high pressure that causes problems such as you report. Being so close to the transmitter means that you may well be receiving too much signal which overloads the tuner in your equipment, so causing break up. It will vary by small amounts with different weather patterns, but the weather is unlikely to be the main cause of your reported problems.

Please chack the signal strengths for all the available multiplexes. If they, or any one of them, is above 85% then you have too much signal and it needs to be reduced by fitting an in-line attenuator. They come in various strengths so try a 6dB one first. They are quite cheap to buy on line and be prepared to fit a stronger one of 12dB if necessary to give good performance. Your signal strengths must be between 55% and 85% for SD multiplexes and between 65% and 85% for HD multiplexes.

paul denning: All I meant was that a very slight change would mean that your signal would change in a way that would be noticed - it could be any variable.

As MikeP says, get a load of attentuators - you can put them in series, to get the right level. 6km is very close to the transmitter, you've been lucky it hasn't happened before.
