sorry to ask a slightly OT...
is there a good guide to bitrates/sound quality to UK radio.

Satellite >= DVT > DAB, but where is FM?
Also is there a list of bitrates anywhere for the TV sources?

Other than Radio 3, I find the dynamic range compression to be the quality killer on most broadcasts.

128kbps AAC on iPlayer for all BBC national stations is fine.
192kbps MPEG-1 layer II for the main BBC national stations on DSat and DTT is OK (for a long time in the mid-2000s, DSat was a far better feed than DTT even though the bitrates were the same - I no longer have DTT to compare)
DAB is for portable mono radios.

For BBC nationals, FM depends entirely on reception, has equal or more DRC on all networks, is always NICAM fed, but avoids AAC/mp2. Some people claim it sounds better, but I think that's down to the extra DRC and noise.

Cheers,
David.
