The symbol shows the location of the The Wrekin (Telford and Wrekin, England) transmitter which serves 280,000 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 The Wrekin (Telford and Wrekin, England) mast?

since changeover I have lost a lot of channels including sky news, constant retuning makes no difference, does your information mean its lost until september ??

keith - if you plug your postcode into top right of this page, then select "Digital Trade View" you will see that you should be geting everything strongly from very nearby Sutton Coldfield.
So why are you on the Wrekin, if you are?

Brian - I hope you won't mind me mentioning it, but your notes "If you have..." may not be very clear to someone unfamiliar with the concepts involved. Might be clearer if they showed as hyperlinks needing to be folloewed without hovering?

Steve: The useful time that any given pattern of carrier data ('symbol') is on the air is either 2,048 or 8,192 time units. In 8 MHz-wide channels as used in the UK, a time unit is 7/8ths of 125 nanoseconds. The useful time is 224 microseconds (s) for 2K mode. For 8K mode it's 896s. It's a modulation rate of 1.116 kHz for 8K and 4.464 kHz for 2K.
The number is quite closely related to the number of carriers within the 8 MHz bandwidth of a channel: in 2K mode, there are 1,512 useful carriers and in 8K, 6,048. There are also a number of extra 'pilot' carriers that indicate the edges of the band and carry information about how the data is encoded, bringing it up to 1,705 for 2K mode and 6,817 for 8K. Why this number? It works better for the mathematical process that works out what the value of each carrier is.
The more carriers there are, the more memory the digital signal processor needs to perform the Fast Fourier Transform algorithm to determine the amplitude and phase of each carrier. The 8K mode would cost more to implement, so some early receivers only implemented 2K mode. The 8K mode is more resilient, though, as narrow-band interference knocks out fewer carriers, and because of the longer duration, is more tolerant to echoes and reflections.

Thanks Mike. My knowledge of transmission stopped at SSB, so I have some catchup to do! This is good
Quadrature amplitude modulation - Wikipedia, the free encyclopedia
Turning to reception; just had a play with the kitchen TV (first floor; set-top loop Ae only, clear view through trees to the Wrekin 30 miles away). Chs 53 and 57 are better, but 31 worse. But added back my evil booster which makes all usable. Only snag is you stand in the way when at the main food prep place!
Have retuned proper TV with rooftop to get Sutton Coldfield Analogue - only 17 degrees different direction, so now have back-up and quick channel hop. (LL145HD)

Hi Steve,
We are behind a big hill and cannot get any reception from sutton, although our next door neighbour can, its sounds wierd but it's true, hence we point to the wrekin

Sounds feasible - though extreme. How far apart are your aerials?
Could you try your kit on his aerial?

20 yards apart, and no , could not share aerial, this situation is common here, look up the street and you see aerials pointing in all directions, maybe I should try to point aerial to Brierley Hill

keith: Looks like everyone is using long poles to get a decent signal from Google Streetview.
You won't get a signal from Brierley Hill, if you can't get Sutton Coldfield then Bromsgrove is OK, but you will have to wait until 28 September 2011 for the commercial multiplex, The Wrekin will give a good signal from the same date.
