When I think back to the time that colour tv started in the UK, I can remember that for a couple of years before the official launch the BBC did numerous, regular test transmiions (anyone else remember these?). My father worked in the TV broadcast business and a result we were lucky enough to be early adopters. I can distinctly remember the excitement of picking up an unadvertised transmission of Star Trek (the original series) in colour (when it was still officially only broadcast on BBC VHF 405 lines). It can't be too far off before BBC start some hi-def test transmissions. Or have they already? Anyone know where to look, frequencies etc?
