DSO: BBC2/ITV analogue channel swap?

Is there a point to this, especially as the new arrangement only lasts for
two weeks?

Is there some reason why the new high-powered Mux can't simply occupy the
space left vacant by BBC2 analogue?

I think it's supposed to give people who haven't done anything a chance to
get new equipment before they lose analogue altogether.

But they could still do that if ITV1 stayed where it was.

It depends what allocation the post DSO PSB mux has been given, and whether or
not that happens to be where BBC2 analogue is, as well as all the other
considerations of trying to not cause interference during the whole DSO
process. Also PSB 1 is allocated a position where it will have maximum
coverage, that may not necessarily be where BBC 2 currently is.

In some cases, Oxford and Crystal Palace for example, BBC 2 analogue occupies
allocations that Ofcom are selling off, Ch 63 and 33 respectively, so there
will be similar swaps there, (C4 at Oxford, ITV at CP)

These swaps have been very poorly publicised, and not really properly
explained at all, but there you go, add it to the list of DUK mis-management.
I'm surprised that DUK pink van isn't sporting a riot shield on its windscreen
yet ;-).

I've done some quick totting up, at the following sites ITV has done/will move
to BBC 2's allocation for the two weeks:-

Angus
Beacon Hill
Carmel
Crystal P
Emley
Mendip
Presely
Sutton Coldfield
Wenvoe

At these sites it's BBC 1:-

Belmont
Dover
Llanddona
Pontop

And at Oxford it will be C4

All the other main stations BBC 2's old allocation is used straight away for
PSB A.

I can't speak for other regions but BBC2 from Sutton Coldfield previously
had the best coverage of the local UHF group being on the lowest frequency
(although the difference between BBC2 and ITV was marginal) so I have to
assume the shift is related to interference in another area.

It may be tied up with the fact that until relatively recently Ch 40
(and 39) were to be sold off.
Ofcom as part of the EU wide '4G LTE' scheme have swapped round the
flogging
off, so now 39 and 40 are being retained, and 61 and 62 ditched. (This
spells more retunes before
2013 at Waltham and Mendip, (and many more)).

It could be that plans were too advanced not to use Ch 40 at SC for
BBC A ?

By the way, I'm currently in SC-land myself, in Leamington Spa.
Interesting
behaviour from a Sony TV (same chassis as Bob Latham's AFAIK).

Here SC is the main Tx being used, but a very strong signal is also
available from the Leamington relay.

I ran a full rescan, and SC's BBC A channels were all correctly placed
on primary LCNs.
The Mux B duplicates are all at 800+ (as expected) but it *totally*
ignored BBC A from Leamington (UHF Ch 59).
If I manually tune to it, it sees all the channels, and asks me what
to do with them.

However, left to its own devices, it totally ignores the relay station
(which is a Good Thing !)

How's Belmont?!

The whole thing seems to be very complicated, with different models from
the same manufacturer behaving differently. I wonder why there is such a
lack of standardisation?

Nothing there.

I was also surprised not to get anything sensible from Lark Stoke, pre
DSO there was
a mangled analogue signal co-ch with The Wrekin. I suspect the SFN DTT
signals
are destroying each other because the signals are beyond the Guard
Intervals at this location ?

So that means a retune for Winter Hill at some time?

Yep !
