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 Seaham (County Durham, England) mast?

I live in Seaham currently, we have recently changed our Ariel in a hope to get a better digital signal, fortunately the signal had increased and more channels became available.
however even the increased signal is often terrible. I have heard rumours that after the digital switch-over the digital strengths can become better.
I was hoping someone may be able to tell me if that is true or not?

Daniel: These relay transmitters exist because there are areas that were not covered by the main transmitters, for analogue services.
At switchover, the relays will only transmit the three public service multiplexes: the services listed above.
If you're getting good quality analogue signals from one of the main transmitters now, you should get reliable digital signals after switchover. Virtually every transmitter in the country will be getting much stronger digital transmissions, at least equivalent coverage to analogue and sometimes more. (The only transmitters *not* getting much stronger digital are those where it was already practically equivalent.)
If you provide a full postcode we can work out which transmitter is most likely to provide the most reliable service.

Seaham
Post code SR7 8LA.
Despite having a good quality aerial installed, digital signal quality is still erratic (small burst pixelation and picture freeze). Signal strength is 75% and quality varies on digital channels from 75% to 100%.
Is this likely to improve?
Is the redcar transmitter the best option for SR7 8LA? as that seems where all the aerials in my location are pointing.
What will the Seaham relay station be transmitting at switchover?
Are portable digital receivers (pocket devices) going to receive signals, as currently they pick up very little unless you move round the house bending the antenna in multiple positions while you earth yourself to a radiator. Analogue portable devices received signals perfectly!

Alan: Digital UK reckon the best transmitter for you, both now and after switchover, is Bilsdale West Moor. It's not that near Redcar; it's actually the other side of Middlesbrough.
Bilsdale transmits currently at 1.6 kW to 6 kW depending on the multiplex, compared to analogue at 500 kW. At switchover the digital signals will be 100 kW for PSB channels, 50 kW for COM channels. These levels are intended to give equivalent coverage compared to analogue for the COMs and slightly more for the PSBs.
The commercial multiplexes will be out of group after switchover, and you will need to change to a wideband or Group K aerial to get them. If you have *already* got a wideband, that might be the cause of some problems as they don't have a lot of gain at the lower frequencies currently used.
Results are currently expected to be variable on Mux 2 - carrying ITV1, ITV1 +1, ITV2, C4, C4+1, E4, More 4 and C5 - and Mux D, which carries Yesterday, ITV4, Film4 among others.
The Seaham transmitter will be 'Freeview Light', carrying only the public-service multiplexes: the BBC's channels, the ones I listed earlier for Mux 2, and the HD services BBC One HD, BBC HD, ITV1 HD and 4hd. By the time the Tyne Tees region has switched, BBC HD may have become BBC Two HD, and a fifth HD service may have joined the line-up.

new to freeview and missing all the COM multiplexes. Live in the SR70 area. Picking up the PSB channels fine, good signal etc. Aerial in loft, brand new 48 element high gain. Noticed the Bilsdale transmitter is not green in my area on the coverage map. Do I have any options?

Dave: Are you picking up the PSBs from Bilsdale? If so, perhaps putting the aerial outside will give you the COMs as well.
Or might you be able to receive from Pontop Pike instead?
Like many places by the sea, inland from Seaham the ground goes up which is why it has its own relay.

Dave Lindsay: How do I know where I am picking up from??? I think I am picking up from Seaham relay although I cannot find anything saying this, just guessing as Seaham puts out PSB's and this is what I am receiving.
I am unsure where others are receiving but most people have sky etc. I have pointed my aerial in the same direction as theirs (which I know is rough direction of relay) and this is what I get. On the coverage map, Bilsdale is not green over my house, does this mean I will not receive from there?
