The old Ally Pally BBC TV transmitter used double sideband
transmission, all subsequent 405 and 625 line txs have used vestigial
sidebands, and I think this included Crystal Palace 405 when the move
to there was made in the 50s ?

Yes indeed, though there would still have been some DSB receivers around
at the time that would have had to be modified.

but Pawley states:

Many of the 20,000 to 25,000 receivers that had been in the hands of the
public immediately before the war had suffered from lack of use, from damp,
andin many cases from enemy action. It is doubtful how many of them
survived to be used again when the service was resumed in 1946

That's when we missed the chance to change to 625 lines.

Pawley mentions that, too. I simply quote two phrase2 ".. the 625-line
system was not agreed until July 1950, ..."

"To wait until then would have meant denying television to Britsih Viewers
for at leat a further 4 years. thepublic mood .. demanded reassurances
that peace had really returned .... and the resumption of BBC Televisio
helped to meet this need."

A thought: if we had waited until 1950+ for the standard to be agreed,
would as many people been able to see the Coronation in 1953?

In any case, the conversion to 625 was not a major problem because of the
very long duplication time; it was the use of uhf which caused such fun.

Ohh, think of all those ghastly tellys that used to bust into flames when
you changed line standards! What joy it was to solder them into the 625
position when 405 ended.

If they burst into flames, then surely the housholder would get a new set
on household insurance. Wonderful, I'd suggest.

Whilst I'd agree with you that those prudent enough to take out insurance
would not suffer financially, I think that a sudden conflagration in the
living room just as father switches to BBC2 would be undesirable. I admit
the the programmes of the 1960s could be dull and that the small number of
channels restricted choice, but I doubt if many would welcome such extreme
excitement so close to bedtime.
