The symbol shows the location of the Sudbury (Suffolk, England) transmitter which serves 440,000 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 Sudbury (Suffolk, England) mast?

JB, Mux on c60 came in 90% on quality and strength the other day, now back to its usual tricks of flickering between 0 and 90%, no signal.

I have a Humax recorder which is fine. When I try to record at times the television (which is also fine) I get no signal or scrambled. Put on BBC 1 recording and it is really scrambled. Engineers have come 3 times one told me I was in the area where 2 transmitters are close and it is interfeering with my recorder. Could this be true as it doesn't happen all the time. It seems it has a down on me, because it's my favourite programmes it scramble3s mostly. HELP.

Betty Bayliss: It would be of considerable help to anyone offering assistance if you had indicated where you are located, this in the form of a post code or one from nearby such as a shop, as only then can access be made to the reception predictor and which also gives information on the transmitters covering your area.

I'm now the proud owner of a new TV, which has Freeview HD, and a Blu ray surround system.
Whilst recently scanning the HD channels I caught the end of a test card and 5.1 surround check on the BBC HD preview channel. Does anyone know if this test is broadcast at set times? I've looked on the BBC site but can't find any info. I'm hoping to record this test so I can fiddle with the settings when the boss isn't around!

I contacted you last August regarding five 125mt Turbines which were being erected on Earls Hall Farm, Clacton on Sea CO16,between us and the Sudbury transmitter. jb38 gave me a very informative answer & suggested that they most likely would affect our signal.He was right. They have had problems with them (ha,ha)and so they have only been working (intermittently)for the last week. We have three TVs fed by one aerial, all our pictures are still perfect apart from our newest TV which has full HD which pixelates intermittently on the four HD channels. Why are the Turbines affecting HD only? I would appreciate any answers on this.

We live in a bungalow, and have a good quality modern aerial on a tall roof mask, all connections are with W100 cable.Pictures on three sets are really good. Only BBC1 HD, BBC HD, ITV HD and Chan 4 HD on our new Philips set are affected. I have done all your checks,

LandlubberDave: Broadly speaking, digital either works or it doesn't. By "works" I am talking the bit that you can see, which is producing a picture.
HD pictures are more susceptible to such interference.
Of course, this is not to say that the standard definition signals aren't being affected, it is just that your receiver is able to resolve them to a picture. It may be that they are "only just" good enough. As you only measure is the picture, you perceive them has having no effect.

LandlubberDave: I suppose the only aspect about the wind farm issue that could be classed as being slightly fortunate is by the fact of analogue transmissions having ceased, because reception on that mode of transmission can be totally devastated by wind turbines in quite an unbelievable fashion, of course knowing this fact is not really of any comfort as far as your own HD problem is concerned!
That said, there could though be a possible solution to your difficulty, but with this being totally dependant on whether or not you can receive a strong signal from your local Clacton transmitter (bar any obstructions) as although your Sudbury facing aerial is quite a bit out as far as rear reception is concerned, but this fact does not always hold the same importance where really strong signals are concerned, and by your relatively local Clacton transmitter (@ 1.8 miles) having a radiation power of 400watts ERP it "might" still be received at a reasonable (and consistent) strength on your Sudbury facing aerial, and if it was then you could use Clacton for the PSB channels and Sudbury for the COMs.
Fully appreciating that Philips TV's cannot really be classed as being the most user friendly as far as tuning menus are concerned, but you can easily check if Clacton is a possibility by accessing your TV's tuning menu system / manual tune and entering Clacton's HD mux Ch42 (642.0Mhz) but do NOT press search or scan, because on most Freeview devices as soon as the channel number (or frequency) is entered the signal strength / quality its being received at should immediately be shown.
It would though have been of assistance to know the model number of the TV in question.
By the way the other possible station to use for this type of action is Dover (@ 47 miles) and in that case its HD mux is Ch53 (730.0Mhz)
This test might not really come to anything, but its worth a try.
