Oxford switches off its remaining analogue services next week (currently we're between the two stages of DSO, where only BBC-2 has gone). Oxford is a slightly odd case in that it's technically considered part of Midlands stage of DSO, despite taking BBC South programmes, ITV Meridian News and ITV Central adverts... 
Incidentally, watch out over the coming months for rogue appearances of DSO trails on BBC 1 Oxford - Southampton don't switch until next year and there's a fair chance they'll transmit some of them pan-regionally by mistake!

.. and of course the Whitehawk Hill Tx group (Brighton and Hove) moves from BBC South to BBC South East in March next year when Rowridge DSOs. The South East half of the Meridian region DSO in June, so Brighton will be unavoidably subjected to DSO notices, after it's DSO'd !

Those in digital only areas are still hearing irrelevant messages about DSO on BBC Radio so they probably won't consider them odd

My parents in Wrexham have had to do six retunes as Wrexham's on the cusp of Granada, HTV and Central, so it's virtually impossible to provide accurate DSO information for the town as everyone switched over at different times.

Still trying to work out how I'm receiving a full set of multiplexes from Emley with
Aerial pointing 150 degrees off-beam towards the local relay
Aerial vertically polarised (as per the relay) rather than horizontal (as needed for Emley)
Group A aerial rather than the Group B needed for Emley
Aerial pointing 150 degrees off-beam towards the local relay

Have you tried it with a wet piece of string in the aerial socket
What was your reception of Emley i analogue like?
I seem to remember that when switch-over started the new transmissions ended up being a lot stronger than they originally intended, hence all those who got welsh telly. I wonder if they'll end up being able to ditch some relays in the long term?

Emley analogue was unwatchable, mainly due to multipath and ghosting - I'm only about 10 miles from Emley so I think the relay (Cop Hill) was provided due to multipath.
DTT is obviously less affected by multipath so I suspect that the Emley signals are getting bounced back off the Pennines and the polarisation is getting slightly changed due to refraction, just enough that my VP aerial can detect it.

Multipath actually improves DVB-T COFDM signals ISTR, particularly in the 8k mode where the symbol rate on each carrier is lower and the guard band between symbols wider. With the power levels of the PSB muxes often being bumped up very significantly post-DSO compared to their pre-DSO levels, reception should be pretty good.
The same reasoning is behind why you can operate single frequency networks across an entire country using COFDM (as we do with DAB - which is also COFDM) - though we don't do it in the UK with DVB (other countries do)
