Without a post code entered into this website it cannot display the reception data, shown as links in the small blue boxes below people's posts. Without that information it is impossible to assist.

Please provide a full post code so we can examine the predicted reception conditions at your location. Please also check that your TV has tuned in to the correct channel numbers for the transmitter you are using, you can check those by entering your post code into the Digital UK Coverage Checker at Digital UK - Coverage checker

That looks very likely to be local interference caused by something operated on a timer. Please ask your neighbours who use Freeview whether they get the same problem at the same time. If they do, then you all need to report the problem. If they don't then you need to investigate in your own house what is being controlled by a timer.
Many years ago I had a customer who had similar interference problems between 6 PM and 7 PM. It turned out to be a near neighbour who had their own diathermy machine that they used every day between 6 and 7 PM!

You should be getting a reliable signal from Craigkelly according to the Digital UK Coverage Checker as you are only 30km away. As it is apparently mainly affecting just one multiplex I suspect you have a poor connection in your aerial system (that is well known in the trade to be a common cause). So please check all your aerial cables and connections thoroughly. If there are coaxial plugs/sockets please unplug them and then refit them (that removes and corrosion/oxidation that is, again, a known cause). If there is any visible damage to any cable then it needs to be replaced as it could be letting water into the system which is highly undesirable.

Further to that saod by StwvwnsOnln1, Seagry Court is by far the best transmitter for you to use at your location. Both Oxford and Mendip give poor and unreliable reception in your part of Swindon. If you go to the Digital UK Covergare Checker for your locations, see Coverage Checker - Detailed View and scroll down to the Seagry Court entry it will show all 6 multiplexes should be available with good and reliable reception. It will also show you the channels used for the transmissions to help you tune your TV manually.

As StevensOnln1 states, 100% is far too much and is overloading your tuner. Turning down the gain of the amplifier, if possible, will help. You ideally need around 60% to 85% signal strength shown on your TV.

SJ Gale:
FM Analogue is true radio, as is DAB digital - they are both forms of radio transmission. FM radio has few commercial stations whereas DAB has a significant number of them. DAB is a form of digital broadcasting, so has limitations in the range of audio frequencies it can carry, look up the Niquist effect. AM is able to be far better as it can deliver sounds up to around 18 kHz whereas DAB is deliberately limited to 9 kHz. If you want to listen to music with a good range of sound, then FM is better than DAB. In electronics there is a saying that analogue is nearly always right but digital is nearly always wrong. DAB does benefit from a wider range of programming but there are reception problems in several areas and many car radios using DAB suffer from 'drop out' as you drive along, that rarely happens with VHF FM.
The term 'anorak' was in use much earlier than the 90's. it was being used as a fairly derogatory term in the 70's.
One of the main problems these days is that so few actually have any degree of understanding of the complex technoilogies they rely upon for their everyday lives.

If you cannot turn down the gain of your splitter/amplifier then you need to fit a coaxial attenuator into the cable feeding the affected TV. These are available very cheaply from the likes of Amazon and others. They come in different strengths, 3dB, 6dB, 12dB, etc. Try a 3dB first and if that does not reduce the signal strength to less than 90% or so then try a 6dB. Always fit a new flylead between the attenuator and the aerial socket on the back of the TV so the weight of the attenutaor does not 'hang' on the socket.

Hi
I look forward to the Android app being made available. More people use that than do iOS, so I think they must have had development problems to get the Android version working satisfactorily.

A J Alston:
The owner of this website has been having to make changes due to alteration in the hosting of the site. Part of that involved moving the email system and that appears to have been sending multiple emails to recipients. I've been getting several and another 31 today. They are NOT spam. They should return to normal once Briatist has resolved the problems.
