Default Redifusion / Telefusion Cable Radio

A "Bygones" article reminded me of the old "speaker and selector" units we
had at school and many homes had them. Our house hosted a bracket on the
corner that held a Telefusion wire and my parent used to tell me they got
paid 2 shillings and sixpence a year in rental for it.

It got me thinking - was the "network" via a multistranded cable to give
the 4 channels that I think were on offer? Or was there some form of
multiplexing back in those days?

it was a multicore cable; vision and sound were on separate cores, too.

Not on the Rediffusion system I was familiar with.

The sound was baseband 100v line, just like the earlier radio systems,
and the vision was modulated on an RF carrier on the same pair of
wires.

I still see remnants of it strung between houses around here. The cable
is quite distinctive, having the guy wire wrapped spiral-fashion around
it.

There were selector switches inside the house, usually mounted somewhere
near the window where the cable entered. A rotary knob with maybe 6
positions.

I think the wire between the chimneys in this streetview image could
well be remains of a relay system.

First noticed it a few years back while stuck in traffic and in some
places the cables were hanging diconnected between buildings so I
don't think it is telephone line.
It is a road I only use about every two years and each time I go past
a little more cable has been removed/fallen off.

There were remnants of the system in terraced houses I rented in the
80's, nothing live by then that I could detect, there was a website
about it, but the content seems to have been got at by teh kittehs

I never saw it across the roof tops like that. My memory relates to sound
only - I don't think we have vision in our area (Derby).
Each of our classrooms had a speaker and selector switch.

Yes the Rotherham one was multicore, and sometimes the wires got mixed
up and you got sound from one channel and picture from another.

We have several times had the job of removing sections of old Redifusion
cable and bracketry because it had become dangerous.

We had television on a similar system. Only three channels.
The TV had a thing like a piano keyboard.
Cabling ran for miles under the eves of terrace houses.

Though it was TV it was called "Radio Rentals".

No it was just 100 volt lines as I recall, one for each radio or tv sound
channel.
Not very sophisticated in fact.
I'm just trying to remember how the rf bit worked for the stations. The old
TD20 panel was the workhorse that replaced the IF and tuner.
My guess was it was around 10 mhz or tereabouts .
I can remember when 625 came in there was a lot of modifications to be done
for the dual standard system.
Heath robinson would have been in his element.

When colour cam in many black and white sets needed a filter adding to stop
really nasty patterning on bbc 2.

Alternatively, could it be a medium wave aerial? I remember running
one from the top of the house to the tree at the bottom of the garden.

Yes this is what I was talking about.
In some places you had two regions of tv as well, like down in the
Eastbourne Area. the site was up very near Hanningtons current one, and it
got the London stations through a convenient gap in the downs from Crystal
Palace.
The south I think came from Rowridge. They needed some clever (looked like
chicken wire) on the mast to keep out the French stations during lift
conditions.



Those were very simple times when you almost always knew how stuff worked,
not like the black box tech we all have now.

Yes British Relay were also quite big.
A lot of the Welsh Villages used the Rediffusion system. always getting

I'd have thought the travelling community would have had it all by this
time.

It was very high quality cable. You don't find ones like that nowadays.
The TV being piggy backed was not for long runs. I seem to recall mostly
there were octal plugs on the back of the tv and a large what lookied like
multicore wire, but at the box some had coax as well as smaller multicores
for the sound.

Maybe it's a regional thing, but in the Nottingham area the Redifusion
cables were strung mainly from chimneys and corners of buildings,
zigzagging along; and far too frequently one of the spans would be
across the road.

Like this: https://goo.gl/maps/C1Ptz6pTMjr and further down the same
street: https://goo.gl/maps/1CoXQ3KS5gB2 the way the cable is coming
apart on the right there is absolutely classic, and can be seen on
dozens of roads in that part of town.

If you rotate the view 180 degrees, you can see a telegraph pole and the

Unrelated to the cable but are the two poles a few yards behind and

A TV my parents bought, had an octal socket on the back. That was to
enable a wired remote control to be plugged in - an optional extra. I
vaguely remember messing about with that socket, and making a remote
control for it. It used solenoids for the channel turret tuner up/down
action.

Christmas lights. The trams never went that far south, only as far as
Trent Bridge cricket ground. Ditto the trolleybuses which replaced them.

The "new" tram (NET) was originally planned to go through West Bridford
centre, along Davies Road to presumably a P&R near the bypass. Local
residents successfully opposed it on the grounds of noise etc.

So there's still just the bus to the centre, but around one every two or
three minutes. From Trent Bridge to the centre, last time I counted it
was in excess of one per minute.

I think some people in the west of Scotland could get Ulster TV via

matches before someone comments). .

I totally agree with your point Brian. I often used to ponder about if I
could Time Travel, what technology would I take back 100years to shorten
the development time.
Most stuff nowadays would be pointless as one cannot understand its purpose
of method of operation.
When cars went to fuel injection I gave up on thinking that a car would be
a useful exhibit for my time travelling jaunt.

We had them here in Cambridge British relay they were called back then
you can see a remaining multicore in the Google map link below.

1497785017159479/

https://goo.gl/maps/XuRT1Qdve5L2


Back in the early Sixties reception of the main 405 line services wasn't
that good here, BBC came from Crystal palace a very long way away in
south London then in later times ITV started in London and they were
first to supply a decent ITV signal as it was rather difficult to
receive that channel 9 service here from that distance until Anglia TV
started up in 1959.

However the relay proved popular well into the early 70's as ITV London
had a much better program output than what Anglia did.

In later times they were still on the go as the first BBC 2 service was
again from London and very difficult to receive here till Sandy heath
came on stream then once the 625 line TV on UHF started in earnest then
they shut it down.

We use to have to convert TV's to work on the Relay box awful
arrangement it was, and the picture quality deteriorated across the
other side of the town from the mast which until recently was still
standing and its pictured below all 150 feet of it on the left. It was
in latter times used by a firm called Harry Collins and co for two way
radio its now been demolished and harry collins's building has now been
turned into a Mosque!..

that good here, BBC came from Crystal palace a very long way away in
south London then in later times ITV started in London and they were
first to supply a decent ITV signal as it was rather difficult to
receive that channel 9 service here from that distance until Anglia TV
started up in 1959.


in the early 60s my to be in-laws' next door neighbour in Gt Eversden had a
big aerial for Croydon. Mind you, he worked for a well known electronics
company in Cambridge.

Presumably these old remnants of cables from defunct companies no
longer have an owner, so I wonder what would happen if for example a
cable across a street detached and got caught on a passing vehicle
which could have consequences ranging from just a loud noise to
pulling down a dilapidated chimney stack onto some pedestrians.
With the cable company gone would any compensation claim fall onto the
owners of the buildings it was attached to for ignoring a possble
hazard.
I happened to be reading a newspaper in North Devon a few years back
and recall a report of a Bideford Council meeting where they were
discussing the deteriorating state of the defunct British Relay system
and whether the council should take on the task of getting it removed,
I don't know what was agreed in the end.

Yes this is what I was talking about. In some places you had two
regions of tv as well, like down in the Eastbourne Area. the site was
up very near Hanningtons current one, and it got the London stations
through a convenient gap in the downs from Crystal Palace.
The south I think came from Rowridge. They needed some clever (looked like
chicken wire) on the mast to keep out the French stations during lift
conditions.

I think some people in the west of Scotland could get Ulster TV via
cable, which I recall could be useful for football (not UTV's local
matches before someone comments). .


I had excellent reception of Hannington in this part of S London, by using
a second aerial. Only reason I wanted it was different films on ITV late
night.

Yes we used to put them up, usually a 5 by 5 Yagi stack but the old
Jaybeam skeleton slot worked very well indeed seemed to beat the rest
hands down!.



Another Pyeman no doubt!.
