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?

I have encountered the same problem. BEFORE 16/11/11 ALL CHANNELS WORKED FINE. Why has this changed? Extremely annoying.

I was wondering, comparing the ITV regions on this website to the ITV regions you can add and view through the 'Other Channels' facility and then comparing that to the actual terrestrial transmitters, how do they all match up?

For example, there is an Anglia W(west), Anglia E(east) and an Anglia S(south) available through Sky.
Yet this website says that Tacolneston and Sudbury are Anglia East and Sandy Heath is Anglia West.
Is this correct?
Because I would look at the Anglia transmitter location maps and see that Sudbury should show as being Anglia South.

Likewise, there are many transmitters in the Meridian Region. On Sky there is 4 regions, South, East, South-East and North.
But there are 10 main transmitters for Meridian. These show as Oxford (Meridian N), Hannington (N), Whitehawk Hill (Southampton, presumably Meridian S), Bluebell Hill (Maidstone), Rowridge (Southampton), Dover (Maidstone), Heathfield (Maidstone), Midhurst (Southampton), Hastings (says ITV Hastings though presumably one of the aforementioned Meridian regions) and Tunbridge Wells (says ITV Tunbridge Wells though presumably one of the aforementioned Meridian regions).

So which (main) transmitters in the Meridian region transmit Meridian North, Meridian South, Meridian East and Meridian South-East?

Dover, Bluebell Hill and Heathfield for example shows as Meridian Maidstone so with Hastings being 'a stone's throw away' to Heathfield's Hollington Park relay, with Hastings showing as ITV Hastings, I'm wondering if it is actually Meridian Maidstone? Looking again at the transmitter map, it's awkward to tell which transmitters form part of the Meridian East region and which transmitters form part of the Meridian South-East region. I don't know where the 'dividing line' is between the South and South-East Meridian regions.

I'm not sure if Bluebell Hill and Tunbridge Wells would be classified as Meridian East and Heathfield, Hastings and Dover as Meridian South-East.
But then this website says that Bluebell Hill, Dover and Heathfield are all Meridian Maidstone.

Even the Central region on Sky shows as having 4 regions, W, E, S and SW. I know that the Central South region shown on Sky is now actually Meridian North for Oxford (Sky need to update this) so you would think that Ridge Hill is Central SW but this website says Ridge Hill is Central W.

So it would be nice and easier if the ITV regions shown on this website carried the same compass suffix e.g. North, West, South-East etc... such as Meridian South-East rather than the town name i.e. Maidstone. At least they would have the same names they do both on this website and through Sky.

I look forward to reading how this all translates geographically between terrestrial and satellite platforms.
Thanks.

When using the Sudbury transmitter on an aerial put up by professionals last spring I'm having screen freezes and pixelated lines on BBCA Ch 44.
D3+4 on Ch41 and even SDN on Ch 49 at reduced power have been good and clean pictures.
ArqB has been lost since it went to Ch 63 a while back.
But the thing that bothers me is why the BBCA mpx keeps breaking up.
Oh I have retuned my set top box numerous times.
Any sugestions?

Thank you Dave Lindsay for your prompt reply to my post. It is refreshing to find people are willing to help.
I've been a little while reading your link.
As I've done the first two suggestions already I'm left with the third possibility.
That my signal is too strong.
I am considering buying a new TV and getting rid of the set top box entirely.
If I buy a new TV are they configured so that the proposed signal strengths will be accommodated?
Any advise will be appreciated.

I am another frustrated Freeview user. I live in Ipswich and before the changes in July I received all available channels, except when it rained. Up until mid Novemeber everything was excellant, now I have completely lost all the Arq6 channels. I have reset several times but no luck. I thought that the changes would improve reception, like many others my experience does not confirm this. Am I destined for a life without ch4, film 4 etc?

Dave Pearsons: It looks like you will have to wait until 27th June 2012 to get Film4 etc.

Peter. I've got a brand new TV and new aerial. I live two miles from the transmitter and can't get Film4, Sky Sports, etc. I think it's the low power they're now transmitting the TV channels on channel 63. I'm resigned to the fact that I've lost these channels until June.

I'm not sure why they're broadcasting these channels on such low power. Do they think they'll interfere with the analog channels still being broadcast in London?

And they call this progress.
