The symbol shows the location of the Tacolneston (Norfolk, England) transmitter which serves 330,000 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 Tacolneston (Norfolk, England) mast?

I live in Knapton, postcode NR28 0TW, and we get frequent, but of short duration, interference on all channels at about the same times every day. The screen pixelates and sound is lost for a few seconds on each occasion. We are about 1.5 miles distant from the Bacton Gas Terminal. Is it possible the interference emanates from their transmission towers controlling their offshore installations and if so what can we do about it? We are tuned to the Tacolneston transmitter and apart from the loss of signal due to high pressure weather systems from time to time we receive a good signal.

tim : hi jb38
on each of the affected channels, strength jumps between 0 and 31 dbuv every few seconds ,with quality 0%
itv3 strength is 40dbuv, quality is 100%
bbc strength is 51, quality 100%

tim : I suspected that might be the case, and the reason why I had mentioned that its doubtful if a new aerial would make any difference to your particular problem, basically because that any measures taken to improve reception such as the fitting of a more suitable aerial is dependant upon a low strength, but stable signal being there in the first place, and in your case with it not being as far as Ch39 is concerned.
However in cases where one mux channel is erratic its sometimes found that a dramatic increase on strength / quality can be had by moving the aerial slightly to the left or right of its present position, but though its essential that first of all local enquiries are made with neighbours etc to find out if the signal is actually receivable in the first place (mux Ch39 best referred to as (15. Film 4) or (24. ITV4) as in many cases its not due to variety of reasons, but if it is received by others then that indicates that the aerial experiment referred to might bring results, although obviously it wouldn't if neighbours cannot receive it either.
That said though, nothing can be discounted where RF signals are concerned, and the problem on Ch39 could simply be caused by that mentioned in my original reply, i.e: that of a faulty connection on the aerial, but other factors can also be responsible such partial signal path blocking caused by trees, as the blockage they cause to an RF signal can affect some mux channels much more than others dependant on the density of the foliage.
Anyway, I suggest that your priority should really be to find out if others nearby can receive the signal and take it from there.

Peter Kaye: Although the station referred to cannot be completely taken out of the equation as far as your problem is concerned, I very much doubt if its connected in any way to it as the towers seen at the station are used for beaming microwave links seawards, and these would have no effect whatsoever to the UHF frequencies used by Freeview.
As this is problem is known to happen about the same time each day it would be best if you could check with others to determine if they are also being affected, as they may or may not be, and if not then it has to something very local to your own property either by interference being radiated or alternatively injected via the mains supply.
A good way to verify which is to use a small portable radio with an LW (preferable) or MW waveband, and if LW tune it to the side of but not actually on radio 4 and turn up the volume, this followed by placing it near to any mains cables in plastic trunking or just close to a power outlet shortly before the time that this problem is known to occur, because if the interference is injected into the mains then you will hear a loud purr or crackle through the portable.

Peter Kaye: In addition to that said, if the interference is being radiated from some unknown source then use a portable VHF/FM radio with its telescopic aerial fully extended, then as done with the LW radio tune it to a blank space in the band and turn up its volume, because any interference of a non specific frequency being radiated will be heard as a high pitched raspy type noise.
By the way, with this test its not really necessary to place the radio near to a power socket.

We tune to Tacolneston Transmitter (not Aldeburgh). Over the period Saturday 18 May to Monday 20 May 2013 (and even this morning) we have had regular breakdowns in transmission and loss of picture and sound on signal for BBC1, BBC2, BBC3, and BBC4 all on channel 55. Prior to this there were no serious problems of this nature. Nothing obvious has changed in the house or nearby area and the problem is found on different TVs in our house. We have gone through the Freeview reset procedure and checked for Freeview intermittent interference as you suggest.
We live in the Southwold and Reydon area.
1. Is this problem unique to our local geographical area or has this problem been noticed across Norfolk & Suffolk.
2. Have you any explanation as to what the problem might be?

Since the retune , I have been unable to receive any tv stations broadcast on C39 via my loft aerial . I have tuned these stations in using an amplified indoor aerial , but still get nothing from the loft aerial .
| link to this comment |
Kelvin Wilson: If the loft aerial is a Group C/D one - with a green tip - then it might require replacement:
Aerials, TV Aerial and Digital Aerial
Or perhaps it is in a dead spot for C39 and requires moving.

My LG TV was fine until a few weeks ago, when it seemed we can not longer get the HD channels. All the rest are fine, but HD channels all come up as "no signal". Has something changed in transmission.Is there anything I can do about it?
Any help appreciated.
Many thanks

Ralph Manning: Its not really possible for anyone to be able to assist on this unless you provide your location, this preferably in the form of a post code or one from nearby such as a shop / post office, as only then can the details of the transmitters covering your area be accessed.
