The symbol shows the location of the Oxford (Oxfordshire, England) transmitter which serves 410,000 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 Oxford (Oxfordshire, England) mast?

To help you we need a full post code for your location and details of what television you have. It is also worth checking all your cables and connections. Then you should check the signal strength for each multiplex used by the transmitter you are using. Note that signal strengths between 65% and 85% are acceptable but anything greater is likely to give you problems.

MikeP: Thanks Mike. I'm in HP18 0BS. Apologies, I'm not familiar with the terminology - how do I check a multiplex? Cables and connections are all fine.

A mulitplex is a signal that carries several programmes at the same time, one of the key advantages of digital TV. Now that you have given your post code, you will see a number of blue boxes below your post. The one title 'digitaluk trade' shows your should be using the Oxford transmitter. It also shows the channel numbers used by that transmitter. To check the signal strength of each one, going into your television's manual tuning mode and enter one of the channel numbers given - but do NOT perform a retune! Note the strength quoted and then do the same for all the other signals from Oxford. Ideally they should all be between 65% and 85%, lower is too weak and higher generally causes the tuner to overload and picture breakup.

Hi Mike

Have done as you suggested. I have two indicators for each channel; Quality and Strength. Quality is a big fat zero for every channel bar one, which registers a measly 10%. On strength, most are at or around 20%-30% with two channels at 50%. There's nothing beyond 50%.

What now?!

Thanks
Nick

Nick:

Your signals are far too low for reliable reception, which is a surprise as you are only 15 km from the Oxford transmitter. You should aim to have signal strengths between 65% and 85% and no more. So start by checking that all the signal connections are good and that all the plugs are fitted correctly and that none are lose in their sockets. If you are unsure about any lead and/or its connection it is best to replace them as they are inexpensive. Also check to ensure that any aerial amplifier or distribution system is working correctly - don't just assume that because a red 'power' light is lit that all is well as it may not be. One further check is to ensure that any HDMI cable is well away from the aerial cables, HDMI data signals can disrupt RF signals in the aerial cables.

Hi Mike

I've been through your checklist and nothing seems wrong. Everything plugged in correctly and nothing loose. Am I at the stage where I've got to get an expert in to check it over or is there anything more I can do? As I mentioned, all other channels are fine; it's just the HD channels that are missing.

Hi

I am having a problem with a Sagemcom box that appears to have started around last Monday.

All channels are ok via the TV receiver are fine, which is strange because of course the aerial loops through the Sagemcom box. However, the majority of channels are distorted when viewed via the box and it appears to be the 'signal quality' that is poor.

I have already performed factory reset on the box and also the freeview reset procedures.

Graham Hill: I'm not sure where you live in the area but sometimes the boxes play up the sigs are either
too strong or weak,perhaps you can advise,i'm lucky near weston as i get a swamp signal ,reception is possible without any aerial plugged in.It could be the box or lead has developed a fault,please advise if you

Graham Hill:

If the reception on the TV is fine then that suggests the aerial system and cabling are fine. However, it does suggest that the box has a potential fault. Try disconnecting it completely from the signal and mains supply for at least five minutes. then reconnect and allow the box to reset itself, usually another 5 minutes is sufficient. Then check whether reception has returned to normal. If it has then your fine until a further reset becomes necessary. If it happens again that suggests that the box it developing a fault.
