There's also been another change: the cores in T&E (=romex) used to be

Europe to brown and blue.


You make it sound like 'we' were forced to adopt another country's
standard.
Flex colours were originally changed to harmonise the sales of electrical
goods across Europe - in the same way as our electricity supply became 230
volts instead of 240. Without changing a thing. ;-)
The flex colours were chosen so a colour blind person could still
differentiate between them - if, of course, he knew that the dark one was
line...

Permanent cable changed quite recently to the same colours.

Three-phase wiring has been harmonised from red, blue and yellow for the
phases and black neutral to brown, black, black and blue neutral. Yeah,
I know...


Red(L1) Yellow(L2) Blue(L3) now is Brown Black Grey

? - one on band I and at least one on band III, surely? I lived in
(West) Germany in the 1960s and '70s, and I'm sure we could get at least
two channels on band III (yes, I know B and G channels are narrower, but
not that much).


There were some areas with two band III channels, Brussels for instance
on E.8 and E.10. With a bit of luck you could get a Dutch channel too or
a Frech one in the South. We got three Band III signals in Brussels
around 1966 (Belgium French and Flemish as well as France).
This of course would not have meant that full area coverage like the
whole of the UK would have been possible.

Holland had only one channel on VHF, partly because Belgium needed two
in Brussels. I think most of Germany had only one too, except if you
were close to the border between West and East (or Berlin).

For the UK two channels was possible using 405 lines because they used
narrower channels, leaving room for more channels to allocate to
transmitters. Even then, different polarization was often necessary to
separate the signals.

Dutch cable tv provider Casema used a scheme like 24 28 31 35 38 42 etc.
Interference products tended to be out of the used channels.

When tv sets became better over time many more channels were used,
including most VHF channels.

areas?


I can't remember, I'm afraid. I was only 10 +/- at the time! ISTR
"German one" - ARD - was the one on band I, and was pickable-up where we
were (Dortmund, then Muelheim) on the proverbial wet string, and was a
painfully clear picture. I _think_ we could get more than one on band
III.

Or is German topography more amenable to providing large area coverage
with fewer transmitters?


It has as varied topography as the UK, I would say.

(I'm thinking here of the German plains that we were told for many years
provided ease of access for Soviet tanks ...)

There were indeed such plains east of Dortmund; our lot* went there a
lot for exercises. I think they were (are) fairly sparsely populated,
though, so less germane to these discussions: big agriculture area,
IIRR.

Yes - green/red being the commonest form of colourblindness. Though
making one stripy meant anyone could get it. (A physics master - I think

It _does_ seem odd. Not only the change keeping black but for a
different purpose, but also having _two_ of the phases the same colour.
(If that _is_ truly the case and not one of them grey, as some have
claimed in this thread.)

Though on the subject of motors turning the wrong way etc.: is it
definitely true that you always get the same phase relationship between
red, blue, and yellow? (And what happens at star-delta or delta-star
transformers: are the outputs still coloured red, blue, and yellow?)

AFAIK, we haven't had analog TV broadcast anywhere in the US since June
2009. I know that in theory, US broadcasters have into 2015 to make the
switch, but in reality the switchover was highly pervasive on the first day
possible, not the last.



Look again. Some low power transmitters still transmit NTSC. There
is supposed to be one withing range here, but I can't get any TV signals

Those '60s TVs worked fine on CATV, with no open channels. Even sets
from the '50s work well that way. Early CATV was simply 12 VHF channels
deilivered to the TV at 0 dBm to +5 dBm. Some super cheap sets with a
single IF stage and no RF stage didn't work well, but they were the
floor sweepings of the industry and intended for markets where there was
only one or two stations. 'Madman' Earl Muntz made some real crap.

Of course if you are only looking for local coverage you could run several

Its probable that it would be possible to add a second network that only
covered the main population centres, as Analogue Channel 5 did on UHF.


I don't know how well UK sets worked in the 1960's, but US TV sets were

I think the next one up was 5 in NYC and 6 in Philly.

Generally, UK (and even European) TV sets had a hard time with adjacent
channels. Like the USA, the off-air broadcast channels were arranged so
that, within the normal service area, there would never be an adjacent
channel which was anything like as strong as the channel(s) intended for
that area.



That was a problem with very early vacuum tube CATV trunk amplifiers
that were run single ended. They generated a lot of IMD. Even '60s
solid state push-pull Trunk amps had no problem with adjacent channels.
CATV converters only made it possible to add more channels to broadcast
only TV sets. Some converted to a low VHF channel, (Hamlin, Jerrold,
Oak) and others (Eagle) converted everything up to the UHF band. I
repaired in excess of 10,000 CATV converters in the '80s, in a four year
period along with all of the head end equipment.

The ground wires in that picture appear to be in bare copper, borne out
by the person using a multimeter with a probe resting on the ground
wire. If so, that's pretty shoddy. What's to stop it coming into
contact with the exposed hot and neutral screws on the outlet body as
the outlet is pushed back into the box?



Knowing how to do the job takes care of it. It's quite easy to do
properly, since the ground is on the end of the outlet. Once it's
pushed back into the box and screwed down, the solid wire can't move.
That photo is sloppy work, and in most areas you have to use a green
wire nut for grounds. Some require a 'greenie, which has a hole through
the top, for the wire that goes to the device. When all the wires are
connected, the ground is pushed into the back of the box, then the
insulated wires. There is enough room in the box for all the wire. I
wouldn't use the second pair of wire nuts. I would use both sets of
screws on the outlet. This picture looks like it comes from a cheap
'DIY' book for and by people with no clues.

Here is a 'Greenie':

I'm sure it is, but as we've already established that the "exact point in
the same broadcast" bit isn't true its not relevant.

The myth that the engineers simply ceased transmission half-way through a
programme and left the station like a sort of Mary Celeste has been
widespread, but it is a myth. In fact there was an orderly shut down and the
film in the machines would have been rewound and put into storage before the
staff left. It would have been 35mm film (the BBC didn't have facilities for
transmitting from 16mm film pre-war) and thus on nitrate stock. NOT putting
it into proper storage would have constituted a fire hazard and been in
contravention of fire regulations.

Where did I say that they were?


Why mention that they weren't inspected for US use if they didn't need to
be?



The hardware had to be, no matter where it was shipped to. The power
wiring had to meet the standards of where it was shipped to.


And of course they are incompatible with the US market, they are meant
meant to be compatible with a European standard, wasn't that why the
ESA specified them?



Isn't that obvious? They wanted what they are used to using.


Well I thought it was obvious, why I why I queried the fact that you
apparently thought otherwise

I'm also confused by your reference to "foreign tourists", since when
have
tourists bought earth stations?



When have you ever seen brand new, custom built US $8,000,000 earth
stations for sale at a flea market? You are in such a hurry to find
fault that you don't bother to consider the meaning of the text.


I wasn't in a "hurry" to find fault at all. I actually spent some time
reading your post trying to decipher the meaning. But since what you wrote
was so vague and confused I asked for clarification of what you actually
meant.



In that case I apologize.


'Foreign tourists' here on vacation were buying them in Florida and
taking them to Europe because they were a lot cheaper than similar items
in the UK.

You are still being vague. What foreign tourists, and what were they buying?

And finally since when have socket outlets included voltmeters?



Since China sold them.


Well OK, I've never seen one. I doubt that they conform to UK standards.



They had UK outlets, and the 'voltmeter was about 1/2" * 3/4" like the
tiny VU meters that were popular 30 years ago in battery powered tape
recorders.


I could probably go to a flea market and
take a picture of one, if you need convinced that they exist. Even
then, you would probably claim they were fakes.

You appear to think that I am deliberately finding fault with your post. I'm
not, I'm simply asking for clarification of the meaning of your vague and
confused



There are too many sub threads in this thread to keep everything
straight Is my guess. I have had so many comments challenged by o
may different people that it's hard to keep them straight. I did put a
smiley at the end of that paragraph to show I was joking about not
believing a photo.

I've always wondered if somebody might have been seen furtively slipping
out of the back door of Broadcasting House that Monday afternoon before
setting off to walk down to Battersea Bridge with a box of matches in
his coat pocket ...

We wouldn't need to do it, if you Europeans would stop starting World

According to the history books the US entered WW2 because it was attacked by
the Japanese. It seems that Michael A. Terrell thinks that Japan is in
Europe.

Now that I *would* like to see a photo of, because I cannot imagine what
they look like from that description. Wherabouts on the socket faceplate is
the meter fitted? You say they have UK outlets, so why are they not
available here? Why would the Chinese make UK sockets and only sell them in
Florida? it makes no sense.

I'm also still puzzled by the claim that "tourists" are buying socket
outlets in flea markets in the US to bring home with them. Socket outlets
are simply far too cheap here to make it worth the bother and expense of
purchasing with foreign currency and then having to pack in one's
weight-limited luggage.

"Look what I've brought you as a souvenir of my holiday in Florida, its a
cheaply made Chinese copy of a BS1363 outlet",

I can't see it somehow!

Wouldn't surprise me, seeing the average American's knowledge of
geography. A very insular country.

Also, what about the current sabre-rattling over Iraq? There's some
right-wing American pols very keen on another war in the Middle East.

I would agree with that but then, 'tourists' are a peculiar breed! If
they've never looked further than the local High Street or shed they
might expect to pay around £5 (or more)

sockets/mk_white_range/MK-Double-Socket-White-13A-9289618

or http://tinyurl.com/7fkucwo

rather than a little over a pound:

or http://tinyurl.com/65bp6m7

although the price in dollars - $1.85 each - looks much higher.

How cheap do they need to be to persuade 'tourists' to buy them ...?


"Look what I've brought you as a souvenir of my holiday in Florida, its a

Of course it is quite likely that many that are sold in the UK also
originate in China ...!

The US was already active in the war, but not officially. US volunter pilots
were flying missions against both Japan and Germany. THe US was providing
equipment and supplies on a "lend lease" program that allowed them to do it
for free, without violating the official neutrality polices.

US ships were acting as "human shields" to shipping convoys in hope that
a U-Boat would miss their target and hit one, allowing the US to enter into
the war.

Bear in mind that although Roosevelt was pro-war, a lot of people in the US
supported Hitler or wanted to remain neutral. He was just waiting for
an excuse to enter the war.

It was just a matter of time, and a fortunate one. If Japan had not attacked
on Dec 7, 1941 and the US did not enter the war until 1943 or 1944, it would
not of gone the way it did.

Looking back in hindsight, it would have been very likely that if Europe was
not invaded in 1994, by 1946 the Luftwaffe would of had a jet engine
bomber that was undetectable until 20 miles of the coast, able to
fly to New York and an atomic bomb to drop from it.

There was a Discovery Channel show where they built a mock up of the design,
you can find it on the internet.

But you are right, the history books, as least as everyone remembers them
says that the US entered the war because the Japanese attacked.

Yes.

No, the phases are *NOT* brown, black & black, they are brown, black and

Serves me right for not having my morning coffee BEFORE I type anything.

It should say 1944 not 1994.
