It's a real pity, the US Military has dibs on the frequencies that DAB (digital audio broadcasting) need to work well with.
Radio in Australia has never sounded so good since we have gone to DAB+. I can say it's almost like CD but free of charge, and now we have hundreds of stations to choose from, where with FM it wasn't even half that.
DAB uses a wide-bandwidth broadcast technology and typically spectra have been allocated for it in Band III (174–240 MHz) and L band (1.452–1.492 GHz), although the scheme allows for operation between 30 and 300 MHz. The US military has reserved L-Band in the USA only, blocking its use for other purposes in America, and the United States has reached an agreement with Canada to restrict L-Band DAB to terrestrial broadcast to avoid interference.
