The symbol shows the location of the Mendip (Somerset, England) transmitter which serves 720,000 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 Mendip (Somerset, England) mast?

we have for the last 2 or 3 weeks been having problems, have retuned numerous times to have a different outcome on every occasion, our signal was fine before.
Have done the unplugging and clearing .
Can seem to get HD sometimes with no normal channels. Burnham on sea

Rob Wilkins: Pleased to read of your success with regards to sorting out the reception problem on your mothers TV, but when say that the initial advice given by the Philips rep of carrying out a full retune did not work are you referring to "reinstall all services" via the installation / service set up menu?

phil: If every time you carry out a rescan the outcome is different then thats inclined to indicate that you might be intermittently picking up channels from another station, however its not possible for anyone to be able to assist without having knowledge of your post code or at least one from nearby such as a post office etc, as only then can details of the transmitter covering your area be accessed as there are two Burnham's.

We are yet another load of Tauntonites with no BBC channels, and progressively losing others as well. Tempers are a lot more than frayed here, I can tell you. We are in the stratosphere about it. This is a public holiday and 27 March was an asinine date on which to do the change when we all know that there is this problem on every one of the many occasions on which we are told to re-tune. Now, above the box that I am writing in there is a statement to the effect that if a I am disrespectful or rude I will be counted out. OK, so, since I now feel very much that way about the transmitter, how is it justifiable that this is one-sided? Eh?
The practical problem is that I can find NO WAY of contacting the people who do the transmitting at Mendip. I can imagine just why this is, of course. But I have now contacted OFCOM and I will be filling up their form every ten minutes until I get action. And then I shall be doing what I can to get back a proportion of my licence fee.

I'm in Chippenham, I have this kind of problem every time they do this kind of work. I think it has something to do with some new flats that have been built. didn't have any problems until then. Anyone realy desperate may want to think about FREESAT. Satelite seems to work pretty much anywhere in Europe, maybe even further afield who knows?(and they don't have TV licences to watch what us mugs pay for).

We shouldn't be sitting here and grumbling, you know, or sticking bits of wire in holes. We should be contacting the transmission firm. In droves.
All transmitters, so far as I can see, are owned and operated by Arqiva. 01962 823434, Crawley Court, WINCHESTER SO21 2QA.
Now, here's a thing - go on their website and you find they don't give you an email address. Oh dear, they must have forgotten to put it on. Or perhaps I am really a terrorist. And then you find that all enquiries to them about transmission problems are referred to the BBC. But then, of course, you find you are fobbed off again on to a TV Transmission Enquiry Service. Never mind, you press on and fill in their form. About twice, of course, as naturally it is of course a truly wonderful, exemplary form, that will give you such amusement going through all the pages that you will enjoy it far more than watching the boat race which is on about now and which I would like to be viewing.
I suggest you all fill in this form. A lot.

Just a general observation, speaking as a Taunton resident who has lost all BBC channels. It is tempting to believe that there is some fault with the transmitter, but the fact that many people in this area have not lost BBC militates against this theory. So I started to look more carefully for any technical problems closer to home. I found the article on "single channel interference" on this site to be very helpful. Following the advice, I disconnected my HDD recorder and connected the aerial cable directly to the TV. Bingo, BBC came back. I cannot leave it disconnected, so I am buying a new wide band aerial and amplifier in the hope that the improved signal strength will do the trick. There has to be a solution to a technical problem like this and it is more likely to be found within these four walls than on top of the Mendips.

John Crabb: Well yes, but by removing the HHD recorder all you have possibly done is to slightly increase the level of signal reaching the TV, the positive way of verifying this one way or the other being to carry out a signal check prior to removing the HDD recorder, then one after having done so.
If all of these numerous people who complained of losing the signal simply done so because the level dropped "very" slightly, then their equipment must have been operating at a signal level that was sitting just above the cut off threshold and no more, something I very much doubt.

John Crabb: If your HDD recorder is fitted with an RF modulator it will be necessary to change the output frequency to one that does not cause interference. Alternatively an HDMI lead, if one is in use, or even an aerial fly lead might need to be re-routed in relation to the recorder or TV if interaction between them and a tuner is causing the problem. As you rightly say single frequency interference is usually the first thing to check for, along with faulty cables or connectors. If one frequency is abnormally weak compared to the others it is sometimes necessary to reposition the aerial slightly to move it out of a null for the troublesome frequency. It does appear though that an unusually large number of people are experiencing problems over what was expected to be a straight forward change of frequency. This does therefore raise the question over whether there is a problem on C49 (and C48) with the signal being unintentionally weaker than the others.No doubt Arqiva will check that in due course. There is of course the additional problems of communal aerials that have never had to receive C49 before, so lack the necessary channel filter and a larger than usual percentage of viewers who are equipped to receive from two transmitters, who might now find that BBCA on C49 from Mendip is now out of range for the filter on the Mendip aerial, requiring a change of diplexer to restore reception of all services.

On my last message I stated I had a digibox ,this should have been a freeview box. I have noted that there is a problem with Philips equipment. My freeview box that will not get BBC channels is a Philips. Should I have bought a cheaper less reliable Currys one?.
