The bit about remote receiving sites was interesting. Was it
factually correct?

I was sent to a link to an interesting article about Marconi on this
website but noticed there also.

Television Transmission and Production from Dover



There is also an article about Swingate

Nicely written by a local historian, rather than an engineer. (Of course
she may have an engineering background.)

Yes, but as international contribution circuits. More info on these mb21
pages.

The first link is about Tolsford Hill - scroll down past the pictures of
the concrete monstrosity to the article about the cross channel link.







As the article says, when MF radio was established it was with the West
of England Home Service, not London. When I started my training in
Bristol Control Room in 1970 it was said that Bristol fed Brighton,
Bexhill and Folkestone because GPO circuits were routed that way rather
than over the South Downs.

I always thought this to be a less than accurate reason, as we could
have fed the London Home Service instead - it might have been more
relevant to the listeners. However, that was the official reason given.

Shortly before I left my spell in Control Room, one morning a listener
phoned from Bexhill. There was, he said, a frightful noise on the Home
Service which sounded something like a Hoover.

We of course denied this, but then found that our monitoring was
switched to incoming rather than the main West output. Sure enough there
was the noise of a hoover, and glancing around through the window into
the Con, we could see the cleaner happily doing her morning sweeping duty.

Our announcer had left his mic live after the last regional bulletin.

Interesting article. I don't think the bit about Southern TV is totally
correct, and it's contradictory.

Southern TV did indeed launch in Aug 1958, but only from Chillerton Down
(on the IoW). I don't understand the bit about Swingate relaying the
pictures to Dover. The Dover transmitter (aka Hougham) didn't come on
line (as the article says) until January 1960. (Also I think the ITA had
toyed with allocating it to Anglia, rather than Southern).

In short, until Hougham came on line, Southern TV's area was broadly
restricted to west of the A23

Another claim to fame for the Dover transmitter is that, when
the Belgian cable networks opened up in the seventies, Dover
provided the feed for the UK channels.

Considering the long sea path - the operator whose output I
saw had an aerial on top of the water tower in the Maria
Hendrika park in Ostend - I was always impressed by the
quality on my visits there.

And it was considered so important (because of the revenue paid by the
Benelux cable cos to show BBC programmes) that in 2001 the BBC replaced
the analogue transmitters there (the only site, in addition to CP, that
had any significant upgrade/replacement of analogue kit post the launch
of DTT/D-Sat)

Very interesting! Thankyou, Mark, for posting that.

The transmitters weren't junked at DSO though, they were dual standard,
so they are in use today at I think Waltham for COM 7/8 .

What's that word the religious use that means 'all knowing'? Oh yes,
'omniscient'. Mr Carver, you are omniscient.

Interesting document - I wondered what they'd done with the older,
pre-DSO DTT transmitters.
But aren't some of these services DVB-T2? A standard which didn't
exist in 1998, when these tx's were built.
