Las Vegas, NV (January 21, 2004)–NPR (National Public Radio), Kenwood USA and Harris Corporation, Broadcast Communications Division revealed the complete, positive results of the 2003 Tomorrow Radio Project field test on supplemental audio channel (SAC) broadcasting to the National Radio Systems Committee in Las Vegas recently. Tomorrow Radio’s 2003 field tests prove that multiple program channels are fully attainable using iBiquity’s HD Radio FM digital system.
“Multi-casting on SACs is real, and it works better than we anticipated,” said Mike Starling, NPR’s vice president for engineering and operations. “HD radio is no longer just a hypothetical construct. Tomorrow Radio is here today.”
NPR, the leading network and member organization for more than 750 public radio stations in the U.S., initiated Tomorrow Radio in fall 2002 with technology sponsors Harris Corp. and Kenwood USA. Tomorrow Radio is a multi-year research project, funded in part by a $500,000 grant from the Corporation for Public Broadcasting, that will explore, test and demonstrate technologies and services that are compatible with HD Radio.
Tomorrow Radio’s fall/winter 2003 field tests involved four NPR member stations along with NPR’s Tomorrow Radio sponsors Kenwood USA (who provided the test receivers and mobile test lab for the field test) and Harris Corp. (who provided transmission equipment to each of the participating field test stations). Field tests were done over seven weeks, with testers spanning 7,500 miles and collecting over a million discrete data points. The testing documented excellent, nearly seamless city-grade coverage for the all-digital SAC under experimental licenses from the FCC.
