Do they KNOW they are publishing this nonsense?
You could perhaps add an explanatory note?

Steve P: I've put a patch in to change the message to "closed". I hope this is clearer.

Just to point out, your info on the MUXs towards the top of the page is incorrect - COM6 is not yet on C48, but still on C67 - until Sept anyway!

Bob Archer: My apologies, this transmitter has a "type 6" switchover, not a "type 3". I have corrected the database.
Thanks for pointing it out.

jason: Because the channels that will eventually be used are still required at other sites. Both the allocated channels and the temporary ones clash with other sites. Moving to full power now would damage other people's reception, either of analogue or of low-power digital services.
In order of what's going to happen:
On 31 August, Mux A will move from C43 to C31, at the same power level, to free C43 for Sutton Coldfield. C31 is released by Waltham on that date.
On 14 September, ArqB moves from C67 to C48, its final frequency, at full final power level. C48 is in use at Oxford before this date. Mux C changes mode, becoming ArqA, and takes over C67 from ArqB, at the same power level.
On 23 November, ArqA moves from C67 to C52, which is currently used by Tacolneston, at full power. This is its final channel.
On 9 May 2012, Mux A changes mode, becoming SDN, and moves to C51 at full power - this is its final location.
On 27 June 2012, the vertical beam tilt - the angle of the main part of the transmission - will be raised. It is currently restricted to the south-west, to protect services at Rowridge. Effectively this will increase power levels for viewers further away from the transmitter.
