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.
