You forgot to add the smiley!

Just on the offchance that you meant this seriously I'd ask just how many
people in the UK would actually want to watch French TV?

UHF only TV's could not receive it.

Many TVs sold in the UK had multiband tuners, and frequency converters were

easily obtainable. So of all the many factors that stopped the British
watching French TV that one was by far and away the easiest and cheapest to
solve.

BBC's service to the US over cable seems to be pretty serviceable. They
have at least one channel on our local 999-channel digital system, and
they also have a number of offerings on OTA PBS. PBS is a nationwide
consortium of TV and radio stations, mostly initially operated by large
universities.

The last time I was in the States I complained to someone about just how
utterly dire all the radio stations were that I had tried to listen to on
the radio in my rental car. The response was "try PBS" which I did, and
found that about 50% of the output was simply a relay of the BBC world
service.

Maybe it would have been better to have one 625 line network on VHF,
like most other countries used until analog closedown.
Of course going from 405 to 625 would have meant ther was no room for
two networks there.

Of course it could, but harmonizing spectrum with the continent might
have been beneficial as well. Have these plans been published?

It is now time to call in the experts to discuss whether or not

depending of course on how it is going to be used, probably
for making tea.

This should keep the thread going for at least another 50 posts.

Obviously water boiled with AC is far superior to water boiled with DC.
Alternating current jiggles the molecules up more.

Tea should always be made with boiling water.

Well it might, but in practice there don't seem to have been many problems
caused by not harmonising spectrum use with the the continent. To be honest
I think the government made the right decision, the limited VHF spectrum
available in Bands 1 & 3 would only just have been enough for one extra
625-line TV channel.

Have these plans been published?

I read them in a copy of the Journal of the Royal Television Society

published some time around 1961. Can't be more specific than that I'm
afarid.

I'm not so sure about rings, but the doubled voltage looks good to me

I don't.

Think about it - your kettle would boil in half the time

I get it. However, the 2-3 minute boil times I get with our current
technology seem to work out well enough.

I can boil 12 ounces of water in about 2 minutes in my 1200 watt microwave.

I can boil almost 2 liters of water in about 3 minutes in a 1500 watt
plastic pot with a built-in heatnig element.

In both cases the starting temperature of the water is about 45 degrees (F).

When I have people over for tea I set the pot to boiling when they arrive
and then reheat it in a few dozen seconds when needed.

A colleague went to work in the USA and complained about the weedy
kettles over there that take forever to boil. I suggested he take a UK
230V kettle over with him and run it off an extension to his stove
connection (i.e. 220V). Dunno if he ever bothered.

Seems like overkill, given the alternatives.


Oh good, we're going to argue about who can boil a kettle the
fastest... you couldn`t make it up!

OK then.

Assuming it survives long enough, a 120V kettle run on 240V will boil in
less than a quarter of the time. [Note 'quarter', not 'half', as twice
the voltage will provide four times the power.]

Conversely, a 240V kettle run on 120V will take more than four times the
normal time to boil. In fact, it literally could take forever to boil. I
know this to be true as I once took a single-voltage UK travel kettle on
a holiday in the USA!

These apparent anomalies are because, unless it's perfectly insulated,
as a kettle heats up it will radiate more and more heat.

Consider the case of the 240V kettle on a 120V supply. The rate of heat
radiation eventually may balance the rate of electrical input, so a
state of equilibrium is reached before the kettle boils. No matter how
long you leave it (or even watch it), it will never boil. It's therefore
a pretty good guess that, on a 240V supply, a 120V kettle will boil in
less than half the time.

BTW, for my next trip to the USA, I made sure that I took a dual voltage
kettle. I can confidently report that, when on the correct voltage
setting, it seemed to boil just as quickly as it had done in the UK.

Of course it would have been better for the public, but it was better
for the Thatcher administration and business friends and supporters
to sell off the spectrum for commercial use since higher profits
could be made that way instead of tv broadcasts.

I disagree. Many of the new uses weren't about high profits but were
low-power devices used by the public such as wireless baby alarms, wireless
microphones, wireless doorbells etc. All of far more use to the public than
one more TV network IMO.

You do need to realize that many of the programs on BBC America

are in fact programs made by or produced for the commercial

commercial tv network Channel 4.

Actually PBS is a separate organization from the local

Maybe you might want check out the meaning of the word consortium. We can
both be right... ;-)

And PBS is TV only. Public radio stations affiliate primarily to
NPR (some to American Public Media, and even fewer to Pacifica)
not PBS.

Except in a very few cases where they pay PBS to broadcast
the audio from PBS's Newshour.

In the case of the Detroit public TV station, WTVS, is a little
unusual at it has always been non-university owned (the Detroit Educational
Television Foundation) unlike neighboring WUOM Ann Arbor
(University of Michigan) and WKAR East Lansing (Michigan State University).

A typical sign of an Public Radio International affiliate station
(previously known as American Public Radio, the smaller rival
to NPR).

<http://en.wikipedia.org/wiki/Public_Radio_International>

Carrying a PRI relay of BBC World Service is far cheaper than
paying for NPR programming, so many smaller public radio
stations prefer this option for obvious reasons.
