BBC1 Testcard F (2)

The BBC digital testcard appeared in May 1984, with no caption generator to overlay the channel identification caption in place as yet until the autumn. There were differences between this and the optical version of F which was scanned by the Rank Cintel scanner which was a very expensive piece of equipment. On BBC1 the test card shown on BBC2 was used on both channels so as to provide a consistent test signal on both networks so a BBC1 overlay caption was shown on the BBC1 feed, and this was also the case on the PM5544
