Digital Radio Update - April 21, 2010
AM operators get IBOC digital options, Digital Economy Bill changes British radio, a portable receiver combines HD Radio and Mobile DTV, iBiquity shows Active Radio EAS and FM HD Radio reaches maintstream at the 2010 NAB Show.
IBiquity's new modified MA1 specification allows broadcasters to sacrifice a degree of digital throughput in exchange for a somewhat higher analog bandwidth and a commensurate noise-floor reduction in analog receivers.
The legislation includes six specific provisions designed to facilitate a transition to DAB-only for the BBC as well as larger commercial channels, while improving the lot of smaller regional and community stations, expected to remain on analog FM indefinitely.
The device utilizes a compact HD Radio module as well as Radio Shack's Gigaware iPod accessory.
IBOC Across America
There are 66 stations in the Old North State broadcasting 108 HD Radio channels.
Eye on IBOC
HD Radio has become more of a fixture than a question mark, at least on FM.
The technology provides continuous monitoring regardless of the device being turned on or off.
