The symbol shows the location of the Hannington (Hampshire, England) transmitter which serves 470,000 homes. 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.
This transmitter has no current reported problems

why is it that at times all digetal channels work perfectly and then whit out any reason suddenly stop working and picture breaks up or message not tuned appears, then in a few hrs time works again .all over xmas period working fine, at 10pm tonight stops working. this is a problem we've had for last 6 months. hannington transmitter. we are in kemptshott, basingstoke rg22 5jq

Although I am on the Midhurst transmitter, I think a great many digital reception problems come down to the changes in weather/pressure throughout the day and these cause the breaking up that you mention David.
What I would like to know is why can I receive one Mux perfectly well and yet, at the same time, another Mux with the same signal strength has zero signal quality and, therefore, no picture? They are all coming from the same transmitter. If the signal strength is the same, why the difference in signal quality? This is not a continuous problem, as I have mentioned above, and can change by the minute.

Mr Mathlin, there is nothing from Hannington that would cause your problems as Kempshott area receives a very good signal - possible exception being area near to Pack Lane traffic lights. I expect that either your receiver/TV that is receiving Freeview is faulty or you have a poor signal due to cable or aerial misalignment that is only just working - thus causing it to 'drop over the edge' intermittently.

Thank you, Brianist. I have now looked at that. I assume Mux 1 is 64QAM but this is the one we have most problems with.
I assume Mux 2 is the other 'strong' signal. This one is always perfect and the signal quality always 100%. I just can't fathom it out.

Ann: Mux 1 is 16QAM 3/4, Mux 2 is 64QAM 2/3. Mux 1 provides the majority of BBC channels (BBC Four/CBeebies are on Mux B), Mux 2 carries ITV1, C4, Five and a few associated channels.
The raw signal strength means pretty much nothing. If two people are talking quietly at the same time, the overall volume level might be the same as someone talking loudly, but you won't be able to work out what either of them are saying. What's important is the level of interfering signals, and that depends on where you are and whether the signals are reflecting - echoing - off any surfaces between you and the transmitter.
The signal levels are always subject to 'fading' - changes in the air pressure, temperature and humidity affect how the signals travel through the air, just as fog affects transmission of light (which, after all, is just another electromagnetic wave, just with a much higher frequency). It can affect different frequencies by different amounts, or the transmitter causing interference on one frequency may not use the other frequency at all.
Digital UK's predictions are made on the basis of the known variation in fading and the predicted signal levels arrive at a given point from all transmitters in their system. It actually predicts no service from any transmitter for you at the moment. You should get best results from Rowridge (vertical polarization) after switchover in 2012. The predicted coverage from Midhurst is poor.

Thank you, Mike. How strange that Muxes 1 and 2 are not both 64QAM, though. Which is the other 16QAM Mux? I hazard a guess that it is Mux C, since this is the other one we have problems with, albeit not as much as Mux 1.
The problem we have is that there is a hill immediately behind us and so we do not receive as good a picture from Rowridge as the one from Midhurst, although everything indicates that we should - the predictors just don't seem to know about the hill! Although an automatic tune picks up channel 34 from Rowridge for Mux 1b because the signal is stronger, channel 56 from Midhurst gives better signal quality and so I manually tune to that.
I remember you saying before, that channel 34 from Rowridge and 34 from Heathfield may cause interference, but is there anything else that uses 56 which may be the cause of our Midhurst problems?
As you say, the Digital UK predictor says we will not receive coverage from Midhurst. Is that because switchover will make it worse for us or do they think that we already cannot get any?
Are you saying that things will be no better for us after switchover - or even worse?
I know this should really be on the Midhurst thread, so apologies to all. Thanks for taking the time to help.

It appears that Horndean transmitter uses
channel 56 for analogue BBC1. Is this our problem, do you think?

Does anyone know whether it is still the intention to complete Hannington's coverage to the East after DSO?

Bob: Of course, after switchover the digital coverage will match the old analogue coverage area.
