Can anyone explain why the radio on the end of my desk receives Jazz FM,
Gold, Virgin Anthems and the like all of which seem to be 32K DAB+ but
when I tune to Classic all I get is a data noise (buzzing)? I admit the
signal is not strong but it worked perfectly well on ordinary DAB but it
won't work on DAB+.
Er, help?
stations are AAC V2) What model radio is it ?

Could you clarify the difference for those of us who do not know? I
have found this sentence: 'HE-AAC v2 is optimized for even more
aggressive compression than HE-AAC by adding Parametric Stereo (PS) to HE-AAC'. Does this mean Classic is using less compression (because
it's classical music)? What does optimised mean in this context - that compression is needed for best results or the broadcaster is free to
choose but v2 will sound better than v1? after compression?
Is Radio 3 still uncompressed (on DAB)?

Can't tell but the serial number starts 1527 so wk27 2015?
Curiously I have moved the radio about a foot further into the room and turned it 45deg and bingo, solid signal.
Baffles me!

At least JazzFM and Virgin Anthems are on SDL mux, whereas ClassicFM is
on D1 mux, are other D1 channels ok? Gold probably not a good test as
it varies which mux it's on throughout the country?

So, you're saying DAB gives bubblingmud, but DAB+ gives buzzingmud?
