Just to confirm/clarify, stations like Yesterday & Film4 are being transmitted on C56 (754.0MHz)? I'm getting no signal on C56 at all.

Dave W: Information suggests that ArqB is remaining on Ch50 until later on this year, this being the Mux that transmits the programmes you have mentioned.

I see that Mux C /ARQA (CH54) is still showing as 16QAM / 2K mode on this site : it actually switched to 64QAM / 8K mode yesterday (thus seeming to lose power, as did ARQB on CH50).
4 of the 5 SD MUXes are now on this : SDN (CH49) being the exception on 64QAM / 2K mode.

Dale: I have corrected the code to show that now. This is a very non-standard switchover.

Briantist: No problem! as at least you did have the correct information shown in the "Note" section underneath the transmission frequencies, it was Digital UK's trade predictor I thought a bit off, as it was showing the reception possibilities for a channel number that wasn't actually operational which was totally misleading, although I see that's been updated now as well.

Dave W: Just to add to jb38's reply - ArqB is due to switch to Ch63 on 16th November 2011, with a power increase to 2.2kW which may help you.

why are some multiplexes still on low power even though switchover has happened on the sudbury transmitter?
some channels still break up
the ones at maximum are perfect
there are still low power multiplexes
i was under the impression all would be high after switchover
any info would be useful

Darren : you obviously believed the 'hype' in the local and national press.
3 of the 5 MUXes will remain on low power until June 2012.
I sent a long letter on this subject to Ipswich Evening Star 3-4 weeks ago, to try to alert people like yourself to the true situation, but they refused to publish it because it contradicted Peter Monteith of Digital UK, who had given them the 'official' (and inaccurate) line.

Brian : thanks. It is typical that a 'non-standard switchover' would apply to us here in Suffolk et al : I assume the powers that be think we 'country bumpkins' haven't yet got electricity, let alone television ...
