Meridian and London DSO

BBC 1 and 2 analogue Whitehawk is fed by a microwave link, via Findon (near Worthing). I think it's microwave all the way (rather than off air UHF on the Row to Findon link). So it may not necessarily die at the same instant as Rowridge itself.

(Of course Findon is also a relay in its own right)

ITV analogue is fibre fed, C4 is the only analogue that is off air fed from Rowridge.

Whitehawk DTT is, always was, and will continue to be fibre fed for all muxes.

This is what I meant really - very slight delay

It's likely the link to WH is fed off of the microwave link from BBC Southampton to Rowridge.

What will be switched off first is the UHF transmitter at Rowridge, and the smaller off air fed relays will die at the same instant. However, the microwave link that feeds Rowridge (and then onwards to WH) will probably be kept on there's no reason to switch that off quickly. However, if the Findon mid point is fed off air from Row, then WH will die at the same instant.

Of course it might be that WH is switched off before Rowridge anyway.

What's important for the DSO overnight work is that the RF outputs from the analogue transmitters is removed, to allow the new muxes to launch on the same frequencies. Rowridge won't require any physical replumbing of feeders, because a new mast and building house the post DSO kit, but most main sites require several hours of frantic replumbing of feeders (which are 6 inch diameter copper pipes, rather larger than than your aerial downlead )

Which has errors in it, notably that BBC-A at WH will use a parking channel between DSO 1 and 2 (It won't, it moves to Ch 60 overnight tonight, and stays there) Contradicting the correct info earlier in the document.

And the document also contradicts itself stating on page that the Hatch Bottom, Hythe Marina, and North Winchester relays will close permanently at DSO 2 (they will) but on the following page implies they will carry DTT muxes post DSO (they won't).

Oh, and the document title is February 2011, when in fact DUK published it last month.

Poor stuff as usual from DUK

Well done to BBC's South Today for extensively covering the swich off on today's edition, not a peep about it on BBC South East though

Quite a few not happy about losing South Today in Brighton it seems

Well, think about it, there wouldn't be any mention on SET today , would there ?

Seeeing as Brighton will get SET from tomorrow I would say why not !

Because what would be the point of telling existing SET viewers, about a change that doesn't affect them ?!

SET and ST have both covered Brighton and Hove (mainly using SET reporters) for quite some time.

I'm sure tomorrow SET will welcome the ex-ST viewers, but it would have been pointless to mention the switch on SET today, just as it will be equally pointless to mention the switch on ST tomorrow !

I've just watched it on iPlayer and it was a very good item which explained it well.... but the odd thing is that it went out in the second half of the programme despite being totally pointless to viewers up in Oxford

Yep - but it is a pretty soft news story - so would have sat very oddly in the sub-regional chunk, which is usually pretty hard news?

Yes I suppose so. In that case a better solution would have been to get Oxford just to do a bit longer just this once
