The bitrate requirement should be lower for DAB+, although this article seems to contradict that: http://www.engineeringradio.us/blog/2013/11/what-bitrate-is-...

If you live next to the radio tower, perhaps. I prefer to have more sound in my noise than FM can offer.

What sort of aerial are you using?

I ask because FM waves are 2.8 to 3.4 metres long, so a quarter-wave FM aerial should be 70-86cm (28-33 inches) long....

No idea. Car radios etc. They work amazingly well in Oslo, but they're useless out in the bushes. Radio isn't fun when you only hear half the conversation. Give me error correction and lossy codecs any time.

Well, if there's no signal you won't get a result whether it's analogue or digital, In fact, digital works less well at low signal strengths: instead of a noisy, hissy FM radio you usually get nothing ;-)

AM goes further, of course, if AM is available...
