Wogan - Radio 1 at 20 (1987) 

Andrew Smith hmm didn't they start Nicam stereo on Wogan from 1986 but only from the Crystal Palace transmitter ?

@@digitalmediafan - I've heard various stories. I think 1991 was the year that Nicam really took off for the BBC, but I believe there were test transmissions before that, but from (like you said) the Crystal Palace transmitter only and on Channel 4. I thought that was 1989. Nicam stereo equipment was not on sale in 1986 as far as I can remember. I meant someone could've synced it with the "BBC Radio 1" stereo simulcast. You could do that with stereo VHS recorders at the time. Remember, there was a difference between a stereo VHS recorder/player and a Nicam Stereo VHS recorder/player. The former were available a lot earlier.
