More and more radio stations have recently been pulling the plug on Shortwave, and AM broadcasting, in favour of digital. There has been a big push in the UK to get the public over to DAB (Digital Audio Broadcasting) or streaming radio via their mobile phones and computers. But, has the case now been made to "keep" a national simulcast AM radio system, like the BBC's Radio 4 Long Wave in the UK, along with global Shortwave radio transmissions for state broadcasting in emergency?
