Lisa: BBC B on will have a -167 kHz offset, as it neighbours the 'lower released spectrum' on -. If that is ultimately used for TV (still very much up in the air, haven't designed the auction yet, but there wasn't much interest from phone or broadband companies) then the offset might be removed.

While I cannot claim to have read through all 51(!) pages of comments and notices I notice one thing which at least for me would be good to know I notice is missing from this page -- the date that the Pre--BBCB gets shut off.

Obviously it will have happened by the 18th April but I remember hearing it would be shut off along with the BBC2 which will happen on the 4th.

Do you happen to know which if either it'd be shut off upon? (Or even if it's a day in between).

A.M. P.M.:

If you mean the temporary HD mux, this will stay until 18th April, so there will be no break in HD . If you mean the old MUXB, this will also stay until the 18th, as it carries Sky Sports 1 and 2. At , those two channels will move to the COM6 .

this helps,
Adam.

Thanks. I did mean the HD mux -- the others are covered above, and the HD one's labeled 'Pre--BBCB' there in the mux comparisons too.

Wasn't looking forward to a potential loss of the HD for two weeks, so glad I was mistaken.

Thanks everyone for the responses, but I still can't seem to find anywhere the exact frequencies that CP will be transmitting on post (including the +/- 167 offsets).

I know we have a couple of months to go yet, but I need this to manually configure my Media Center PC after a re-tune.
