From Wikipedia: Channel 4 is a British public-service television broadcaster which began transmission on 2 November 1982. The Broadcasting Act 1980 began the process of adding a fourth, and Channel 4, along with its Welsh counterpart, was formally created by an Act of Parliament in 1982. After some months of test broadcasts, it began scheduled transmissions on 2 November 1982. - en.wikipedia.org

Ian.Unless you provide a full postcode or nearby location as such,we cannot be of useful help to you ! IanMonday 16 July 2012 10:00PM
Wisbech ok sorry, wisbech Cambs......PE13 3RP
Ian.Wisbech,PE13 3RP.Sorry for my delayed reply but now you specified your postcode as such,is it only Channel 4 and Channel 5 that are giving you difficulties or is it the entire D3+4 multiplex that are problematic as Channel 4 and Channel 5 are all on the D3+4 multiplex on any main transmitter and relay mast.By inputting your full postcode is your aerial polarised horizontally and if so is it directed at either Sandy Heath,Belmont,Tacolneston or Waltham main transmitters.The D3+4 multiplex from Sandy Heath is on frequency 24,from Belmont it is on frequency 25,from Tacolneston on frequency 59 while from Waltham this is on frequency 54.There is a possibility that single frequency interference could be a likely cause in the affected room as such from an electrical appliance,etc.I would look up single frequency interference underlined somewhere in this text and you may have to perform a total resetting procedure as such.Try bypassing the splitter and see whether any improvement (in the room affected) is made.Or use a set-top aerial (if you have one),a piece of wire or a wee screwdriver inserted into the aerial socket of your appliance (in the room affected) whether that makes any difference whatsoever.
Just out of interest what transmitter/s are you on which i mentioned above,and as an indicator which local news bulletin/s do you receive in your house ? Correction to my location in my above post,Halifax not Wisbech ! leeWednesday 18 July 2012 6:44PM

Bishop Auckland postcode DL13 3AZ i believe my transmitter is the Frosterley relay, i have had problems receiving channel 4 since 17th July 2012 mostly i get no signal then i might intermittently get 5-10 seconds of normal signal. i have checked putting aerial directly into the tv bypassing dvd with the same result tried retuning and the television cannet find a signal had to manualy retune into channel 47. contacted my television provider (as set is 3 weeks old) and he said it was a transmitter fault....would be very grateful for any advice, thanks in advance.Sheila RichardsTuesday 13 November 2012 10:21AM
Southampton My postcode is SO30 2SS. Until recently I was able to receive Ch 4, Ch 5 More 4 etc perfectly well but now these channels keep breaking up and telling me no signal. I have an indoor aerial and retuning does not help. Is this a problem with this area and how can I get stable viewing for these channels? Any advice gratefully received.AdrianWednesday 6 February 2013 10:09AM
Hi,I live in manchester. My freeview has reset itself and I now get s4c on number 4 and chanel 4 on number 8. everything else is as it was. I have tried retuning on automatic and from a factory reset,still the same.Any ideas please.The freeview is built into the tv and my recorder also has built in freeview but that is still as it was.Adrian: The reason is because your TV is picking up and deciding to go with (as a "main" channel) one of the Welsh transmitters, probably Moel y Parc.
Moel y Parc's signals are in the middle of the band and Winter Hill's are further up, so you may be able to have the aerial unplugged for the portion that it scans the unwanted channels.
If the scan gives a percentage as it progresses, then plug in just after 60%. If it gives UHF channel numbers (21 to 69), then Winter Hill's lowest is 54, so make sure you get it in just before it. Adrian: I should add that if this turns out to be a regular occurance, then you may have to see what you can do to stop it.
Some receivers that retune themselves have an option within the menu for it; others don't and just do as they please.
On the basis that your aerial faces Winter Hill and doesn't face Moel y Parc it may be likely that the former's signal is stronger. Placing some attenuation in the aerial lead to reduce the level of all signals may well drive down the Moel y Parc levels whilst still leaving Winter Hill's far enough the threshold so as not to affect your viewing. The hope is that it won't ever get to "see" the Moel y Parc signals because they will have been reduced sufficiently.
An example of an attenuator is here (other models and sellers are available):

If you have an amplifier, then first off reduce its level of amplification if possible as an attenuator works to reduce the signal whereas an amp acts to increase it. adrianWednesday 6 February 2013 2:21PM
Thanks Dave,I'll give those ideas a try.adrianWednesday 6 February 2013 8:14PM
Thanks Dave,the aerial out trick worked.
