The symbol shows the location of the Winter Hill (Bolton, England) transmitter which serves 2,690,000 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.
Are there any planned engineering works or unexpected transmitter faults on the Winter Hill (Bolton, England) mast?

Currently having major issues with C54, all the main HD feeds are badly distorted despite showing 100% signal quality and 100% signal strength. I have been trying to rule out local interference without success, CBeebies HD is just fine as are all the other HD channels on C31.Moy postcode is M43 6FH, ariel is on the roof on a decent pole. Signal strength is showing as 90% or more across all channels.Any advice or assistance would be most welcome.ThanksJames

James Finlan:
Your post reveals the cause of your problems. 100% signal strength is too strong -especially for HD reception. Ideally you should aim for between 60 and 80% strength but as near 100% quality as is possible.
According to the data shown in the blue boxes below your posting, you should have a very strong signal - which may be too strong for good H|D reception. Search this website for 'too much of a good thing' and try what is suggested there.

MikeP:Really appreciate the signpost, it does look like a need an attenuator of some sort, looking on Amazon I can find lots of different types and of varying strengths from 2db up to 9db, sadly I am out of my depth on this and have no idea which I need so it best to just play it safe and buy a variable unit?CheersJames

James Finlan:
I would suggest getting two, one rated at 3 dB and the other rated at 6 dB. Get the coaxial ones as they can be connected into your aerial cable very easily and can even be connected in series (one after the other). So when you get them, try putting the 3 dB attenuator in the lead first, but do not let it 'hang' on the aerial sockets, it's best to get a short aerial flylead whilst ordering the attenuators, flyleads are quite inexpensive. So you should end up with a flylead from the wall socket (if you have one), then the attenuator laying on the floor followed by the existing flylead going into the TV set aerial socket. (The reason for that is that aerial sockets are not very strong and can be distorted by the weight of an attenuator.) If the signal problems persist and the strength is still too high, swap the 3 dB attenuator for the 6 dB one. If that solve s the problems then you've won. If, however, there are still some problems you can add the two attenuators in series giving 9 dB attenuation. Hopefully that will bring your signal strength into the range acceptable to your tuner. If needs be, you can swap the attenuators for a 12 dB type to give even more reduction, but don't reduce it too much as that can then start affecting the channels that have been OK up until now.
In my experience from working in the domestic TV servicing industry until retirement, the variable types are often suspect quality.
Hope that helps?
