Martin: As above, "The commercial multiplexes at Sandy Heath will remain on their pre-switchover channels and powers for a period after digital switchover. SDN will then temporarily move to channel 31 (at 20kW ERP) on 31 Aug 2011, before adopting its final allocation of channel 51 on 18th April 2012. Arqiva A will adopt its final allocation of channel 52 on 23 Nov 2011. Arqiva B will temporarily move to channel 67 (at 20kW ERP) at switchover and then it will adopt its final allocation of channel 48 on 14 Sept 2011."

I'm now picking up everything except ArqB. I understand it's on ch67, and needs a wide band aeriel. My aeriel is in the loft, how can I tell if it's a wideband?

I have noted that the power on CH67 seems to have crept up a bit in the last few days. I can now receive ARQ B MUX albeit a bit patchy at times. I would suggest that those who failed to get the MUX on 13th try another retune. You never know, it worked for me.

Briantist Re 1080i/1080p switch.
If you go to the BBC R & D blog it appears there is no firmware update for this from Sony yet. Toshiba & Samsung sets also are affected in different ways.
I expect it will be a drawn out discussion as to wether or not the set manufacturers are implimenting the freeview spec.

I'm in Cambridge, and I've lost all but one set of channels since Madingley switched off.
I can only get Mux C (Pick, Dave, Sky news, etc). The reception on these channels is fine, no problems seen so far. I haven't moved the antenna, but the reception I am getting is fine, and there's only 12 degrees difference.
I've got an old telly, a Sony KV28DX20U, with a built in digital tuner.
I've noticed that mux C is the only one using 16QAM-2k. Is this just that my TV is too old?

Nathan - IIUC you know that your Ae is 12 degrees off target. The Mux you CAN receive is the very highest frequency, so may be the one least affected by the wrong direction.
12 degrees is a lot unless you are VERY close to a very powerful sender.

For the past three nights I have lost all signal and therefore have had no TV whatsoever for most/all of the evening. I did the rescan as required but this week have had nothing during the evening. Tonight for example, I came in at 8pm and now at nearly 11pm I still have no tv reception at all. It's really annoying. During the morning all is well so I don't think it is my arial, digibox or tv. Until this week reception has been fine. Any advice/suggestions keenly sought before I go dotty without telly.

Nathan: yes, I'm afraid the Sony 28DX20 is on the list of equipment that doesn't support the 8K mode. You'll have to add a Freeview box.
You could try complaining to Sony, see if they'll give you a free box.
