| It is an analogue (analog for you Americans) transmission so there are

In europe (and Czech republic too) it is MPEG1/2 Layer 2 over satellite,
bitrates from 128kbps(in CZ Radio Proglas) up to 192 kbps ("government"
radios), sampling rates from 22kHz to 32kHz. Some radio stations have some
material stored in MPEG1/L2 on harddrive arrays and content is then
transmitted directly without reencoding. Minor artifacts are hearable but
only if you have very good tuner and listening practise.
Local access to transmitters or retranslator is in analog way, but it uses
only non national-wide radios.

30Hz---15kHz bandwidth is CCIR standard

Is only for CD-Audio writing compatibility, but not at real background.

sure!
