A high bit rate I'd imagine, it being a demo, not the real

world.

Nope - IIRC the same bitrates as used at the start of the service.
the
current reduced ones came later.


I've been told they used 256 kbps in that demo. Then when they
launched they used 192 kbps for Radios 1, 2, 3, 4. Then in 2002 they
slashed the bit rates of R1, 2, 4 to 128k and 6 Music and 1Xtra
started using 128k, and Asian Network's in mono and Radio 7's in mono,
and Radio 4 is in mono in the evenings when R5 Sports Extra is on-air,
and R3 is 160k in teh daytime when R5 Sports Extra is on-air

You're sticking up for a national disgrace, Plowman.


But just to point out, bitrates have little to do with actual
reception.


Gosh, how insightful.

The adoption of DAB was the most incompetent technical
decision ever made in the history of UK broadcasting:
