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...
