The Wrekin overnight 18th-20th January tests will affect Sutton Coldfield
An essential part of the tests on the new aerials at The Wrekin transmitter - so they will function correctly on switchover day, 20th April 2011 - full power overnight testing is done.
During the test, all the existing Freeview services will remain on air.
However, the analogue services will be switched off as follows:
Tuesday 18th January: BBC ONE, BBC TWO from 0020 (plus ITV1, Channel 4 and FIVE).
Wednesday 19th January: BBC ONE from 0110, BBC TWO from 0010 (plus ITV1, Channel 4 and FIVE).
Thursday 20th January: BBC ONE from 0150, BBC TWO from 0010 (plus ITV1, Channel 4 and FIVE).
Because the commercial multiplexes will use C41, C44 and C47 at The Wrekin after switchover (and hence, during these tests) this will clash with Freeview multiplexes 1, 2 and A on the Sutton Coldfield transmitter.
This means that many Sutton Coldfield Freeview users will not have usable service overnight during the testing period.
Also, given that Lark Stoke is at 1.26kW AFTER switchover, it is unlikely to be 6.3 kW before.
http://www.ofcom.org.uk/s….pdf lists it as I have given it, actually at 0.03W because 0.025W won't fit in the page.
Ofcom's publication is the official primary source as far as I am concerned.

Briantist, I already said I am completely well aware that Channel 5 comes from Lichfield and that BBC1, BBC2, ITV1 and Chanel 4 come from Sutton Coldfield. You do not need to remind me.
Also, when I said I was receiving BBC1 from Lark Stoke during the hours of The Wrekin analogue shutdown, I did obviously mean I was receiving the ANALOGUE signal of BBC1 off Lark Stoke, not the DIGITAL signal off Lark Stoke.
So this comment was not applicable or relevant:
Stuart: Lark Stoke's pre-switchover digital services at at 25W, about the same as single energy-saving bulb. It is amazing that anyone gets Freeview from there at the moment.
Lark Stoke will be a 1.26kW digital transmitter after switchover, that's 50 times more powerful.

Brian: Stuart was clearly talking about analogue, not digital, services. I missed that you were talking about the current low power digital service. The Wrekin tests clash with BBC Two analogue at Lark Stoke, on C26, and ITV1 analogue, on C23 - both 6.3 kW. They don't clash with any current digital services from Lark Stoke.
Unless they're *actually* testing the Single Frequency Networks that will form between The Wrekin, Lark Stoke, and Bromsgrove, in which case I would expect LS to be temporarily broadcasting the same test signals as The Wrekin, at 1.26 kW.
