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.

Good Morning,
I had YouView installed on Thursday (24th) through TalkTalk.
Whilst I have a very healthy 36 channels to choose from, my problem is that:
I live in Ipswich which for local News, Weather and adverts comes under Anglia.
If I try to watch either BBC or ITV HD channels, I do not receive Anglia but for ITV HD get Meridian and for BBC get This is BBC HD (both for the Sussex/Kent area), which is not my local news, weather and adverts.
I have now spoken with TalkTalk each day since Friday regarding this problem and have now basically been told that there is nothing further they can do to assist to rectify the problem.
Yesterday I got in touch with YouView directly and they suggested that I contact DigitalUK, which I have now done but they just say re-tune.
I have re-tuned my YouView box and my postcode is showing correctly.
I was just wondering if anyone may be able to offer some advice as to where I may go from here.

Mary: There are fewer HD regions due to the cost of providing different feeds.
BBC One HD has one region for the whole of England which means that no regional output is carried on it.
Nationwide, ITV has opted to provide about four or five HD regions and those transmitters whose region there isn't a HD equivalent of get the ITV HD of another region.
The majority of the time, all regions carry the same content. So providing a HD feed for each and every region would only be of benefit for the short periods that they are different.
You say that you get 36 channels but Sudbury broadcasts all Freeview channels. To receive all channels you may need your aerial replacing.
Refer to this page for a list of Freeview services (channels):
DTG :: DTT Services by Multiplex
Those with grey and a bullet in the "E" (England) column apply. There are 36 services on the PSB multiplexes which leads me to suspect that you are not receiving the COMs, which, for Sudbury, may require a different aerial.

Mary: You have to switch to standard definition muxes for local news. This situation is the same for satellite viewers. Eventually, in the event that Freeview only transmits in DVB-T2, the correct local news bulletins will no doubt be provided on HD channels. The situation for satellite viewers is a little more complicated as there are so many standard def. satellite receivers in use. Possibly both Freeview and satellite viewers will be forced to buy HD receivers in the future!

JB/Dave,
Sorry to call on you again but I have yet another problem from Sudbury. You may recall the problems I had with the mux on c60. I have a big aerial, 28db booster, on a long pole in a high location and with no Dutchmen interfering in the winter can now get it. However, the hitherto strongest muxes showing 100%, ie ch41 and 44, are now periodically partially breaking up. Can this happen with TOO MUCH signal?

jb389:35 PM
Nick: Well yes! as it can do, and so unless your booster is of the mast head type whereby its up to a point out of reach you should try a test by either by-passing it, or if it is of the mast head type just connect a variable attenuator in line with it, that is should you have one lying about amongst the various bits and pieces of equipment that I believe you might have there.
Just out of curiosity, did you test to make sure that Ch60 was still NOT being received before you installed your new aerial system? the only reason for asking being that terrain changes as far as reflective properties are concerned that usually occur during the winter months can alter reception whereby some might lose channels and others might gain, this being my reason for asking.
It should also be appreciated though, that the changing conditions referred to can also be to the detriment of a channel that was previously OK before, I only say this in case there is no difference when you reduce the signal.

Thanks JB.
No, could not get c60 before upgrade.
Masthead amp, suppose I now have to attenuate and lose c60.
For your interest, I have been surprised how Dover comes in in winter as well as summer, but have now removed aerial. Before doing so I did a strength test. I noticed the signal was lower on c59, despite the power on that channel being double that of some other channels. Dover uses a group c/d aerial and unlike Sudbury, the channels are not widely spread needing a wideband. To me this shows that signals travel less well on the high channels and that my problem with Sudbury is that they are too widely spread, some with too much signal, some not enough, just can't win!

Clacton-on-sea
Today, Monday 25 February, 2013, at approximately 3.15 pm, I was watching BBC ONE, from the Sudbury transmitter (UHF Channel 44) when suddenly sound and vision went blank, leaving the dark screen, with just the set's back screen illumination present. Within about 15 seconds music was playing but screen remain dark / blank.
My immediate thought that this might be a local Clacton pirate radio station, over powering the Sudbury signal. When the record finished, BBC presenter's voice (Stewart Mc Connie) started talking. The "replaced" sound was, in fact, BBC Radio 6 Music channel (which is also part of the BBC MUX on UHF Channel 44) I then pressed channel 1 on the Freeview remoote and on screen it showed BBC ONE AUDIO, CH. UHF 44.
Then about a minute later, the radio sound was replaced by BBC ONE sound plus return of vision. Did anybody else witness this? I assume that someone at Sudbury station "got their lines crossed" ???
