I also remember that the BBC did some Quad broadcasts on FM (VHF in the UK) Radio 2 - I think the Alan Freeman Show and John Peel Show, both of whom were rock orientated. Some 'in-house' live productions were also done. BBC Radio 3 - The (only at that time) Classical station also did several progs in Quad.....probably from the EMI Angel catalogue, plus 'in-house' productions.
Isn't there a station in Sweden broadcasting in DTS?
Firstly, the BBC never used any of the EMI/Angel recordings for their 'test' transmitions, all classical broadcasts were BBC recordings, mostly from the Proms.
I've been doing quite a bit of research behing the BBC's H/HJ broadcasts in 1977/78,and although there's no official listing of what was broadcast (yet!!!), a document that came into my poccesion a couple of days ago shows the types that were broadcasts:
Radio 1
'Pop' music: 11
Radio 2
Light music, Brass & Dance Bands & Jazz: 8
Special ceremonial events: 1
Radio 3
Orchestral Music (wide variety): 51
Drama: 5
Opera, Operettas: 3
Choirs: 2
Poem (in an electronic music setting): 1
Radio 4
Christmas Carols: 1
Drama: 2
Dramatic Daily Serial (i guess this means 'The Archers' - lol): 12
Natural History features: 2
Special Ceremonial events: 1
Additional Information
a) Approx 60% of these were undertaken as outside broadcasts
b) Some 20% of the programmes on the air during the year *
c) About 10 more were broadcast without prior printed publicity
* It is my assumption that these 'rebroadcasts' were of material that were originally broadcast in the early days in Matrix 'H', but for testing purposes were done in 'HJ', as 'H' had been dropped by the end of the summer of '77.
As to the Swedish Radio Station that experimented with DTS, this may be of interest:
