No, the ABC being discussed was Associated British Cinemas, who held the
London franchise before Thames.

Many were of the opinion that broadcasting on absurdly high frequencies
like 200Mc/s wasn't a practical possibility. 50Mc/s had seemed
incredibly high.

No!

I think you are being confused by Lew Grade's use of ABC for his Associated
Broadcasting Company, which the cinema chain rightly took objection to, and
Grade was forced to re-brand as Associated TeleVision.

The London weekday franchise was held by Associated Redifusion, later just
Redifusion.

The weekend franchise was held by Associated TeleVision Ltd - ATV - who also
held the Midlands weekday franchise.

ABC Television held the weekend franchise for both the Midlands and the North
(Granada holding the weekday franchise for the latter).

Then the IBA forced a merger of Redifusion and ABC to form Thames, who got the
modified London weekday franchise with a new company, London Weekend
Television, given the weekends.

ATV (later Central) got the Midlands seven-day franchise. Granada land was
split into North West and North East with Granada retaining the North West
franchise, but for seven days this time, and a new company, Yorkshire
Television, was given the North East.

Not exactly a merger as such but the creation of a new company THAMES
which was 51% owned by ABC and 49% by Redifusion.

ATV (later Central) got the Midlands seven-day franchise. Granada land
was split into North West and North East with Granada retaining the
North West franchise, but for seven days this time, and a new company,
Yorkshire Television, was given the North East.

No not the North East which was served by Tyne Tees, but the North
(Yorkshire) which was awarded to Yorkshire which was majority owned
by the Lancashire based tv rental company Telefusion.

Humberside and Lincolnshire were added later under the UHF reorganisation
with Belmont changing from Anglia to Yorkshire TV to compensate for
Bilsdale West Moor being allocated to Tyne Tees.

are is that in Hz?

ITA (Independent Television Authority) until 1972. I think ABC was
known as ATV by then though I can't establish the legal name of the
company.

Infra Red from a TV remote control is 320 Million MHz.
That is 320,000 GHz, or 320 THz, for a wavelength of 940nm.

The spectrum of visible light closely matches the spectrum of UHF TV, times
1 Million:
Channel 21: 474 MHz, Red Light (650nm): 460 THz
Channel 68: 850 MHz, Blue Light (400nm): 750 THz

MHz MegaHertz, 1 Million cycles per second
GHz GigaHertz, 1000 Million cycles per second
THz TeraHertz, 1 Million Million cycles per second

nm nanometre, 1 thousand millionth of a metre

It certainly Hz your skin if you get too much of it.

Our first TV, a hand-me-down from my grandparents also in the early 60s,
had one. The converter was on the back of the set, and there was a big
knob which stuck out of the side and had to be pushed in or pulled out to
select BBC or ITV.

That would be a Bush! Probably a TV24 (12" tube, wooden cabinet) or a TV22 (9"
tube, bakelite cabinet)

Picture he http://www.radiomuseum.org/r/bush_tv24tv_2.html

It is in shadow but you can just make out the knob protruding from the rear.

Click on the 2nd thumbnail down in the LH column on the right for a view from
the rear.

Thanks, that looks like the box indeed - oddly I don't have a clear
memory of the set itself but I do remember the converter quite well.
The attraction of gadgets to small fingers, I suspect ;-) I'll ask the
Aged Parents if they remember it too !

The 50/50 company was at first called Associated Broadcasting Company, (ABC)
but this name was disputed by the Associated British Picture Corporation,
who had also taken over a franchise at a late stage, and who also wanted
the name ABC, to match the name of their cinema chain.

ABPC won the argument of prior ownership, so their stations became ABC,
with the ABDC/ITC company becoming Associated TeleVision from 6 October 1955.

UNQUOTE

So the double eye ABC was seen on screen on Saturdays and Sundays from
September 24th, 1955 until October 2nd, 1955, a grand total of *four* days.
