The original plan, drawn up in the early '60s, was to re-engineer Bands 1

it never happened. I guess that the powers that be thought that the

could be more usefully used for other purposes.

Of course it could, but harmonizing spectrum with the continent might
have been beneficial as well.

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.
