We were advised that the adjacent transmitter channel clash that caused the channel with the history channel to be transmitted at reduced power before the retune at Sandy Heath would be resolved with the retune. Since the retune channel 67 is now at reduced power. Please sort it, it is pathetic.

Mike: You were not advised any such thing, multiplex C (aka ArqA) is not due to go to full power until it finds a final allocated channel at the end of the UK switchover process.

I'm in the Sandy Health transmitter, and I'm missing channels in C and COM6ArqB (D), I've searched for channels automatically, reset by doing first time installation, and searched for channels manually, when I searched manually for the channels in 67 and 48 'no new channels were found.' I've also unplugged everything and waiting 30 seconds and searched for channels again after that, but channels like Film4, VIVA, 4music and Dave etc... are still missing. I've gone to every page its told me but nothing is working?
Postcode: LU56DR and the aerial is in the loft.

Still a bit confused...
Which and when do Mux A, C and ArqB go to higher power? i.e. around 170-180kW or do they?

MickO: MuxC/ArqA has mode change (to 8k), power up and frequency change to C52 on 23rd November 2011. MuxA/SDN has mode change (to 8k), power up and frequency change to C51 on 9th May 2012. I am not sure what power MuxArqB is currently using, but the trade predicter does suggest that it is somewhat higher than the other two COM muxes.

I'm quite surprised that so many people in Bedfordshire and Cambridgeshire are suffering reception issues. I'm in Kettering, Northants and my two TVs receive all multiplexes perfectly and the bedroom TV is fed from a set-top aerial. The Eye TV on my Mac has a harder time because the aerial has to "see" through two walls for its signal, but it still picks up the PSB multiplexes absolutely fine.
Out of curiosity, as ArqB is now on its final channel, 48, and now in 8K mode, when will it increase to its final power? (52.3992,-0.7201)

All is clear now, the £15 I have just spent on a booster to still fail to pick up Dave is because the transmitter doesn't have enough power. What a waste of time and money. A 100% botch end to end. Utter disgrace. If they weren't ready, they should have waited. Maybe better to start downloading the few things worth watching on line instead. No, can't do that, the copper cable has just been stolen at Oakley. 21st century?

Charles Stuart: ArqB goes to full power during March 2012.

Darren: A booster won't create a signal from no-signal, and generally speaking digital signals are usually made worse by using boosters.
You didn't provide a full postcode so I can't really comment about the specifics, but note "Arqiva A will adopt its final allocation of channel 52 on 23 Nov 2011".
