The National Association of Broadcasters’ annual convention just wrapped up in Las Vegas, and HD Radio proponents used the event to begin the push to make the AM dial all-digital.
At a panel on "AM Band Revitalization" moderated by Republican FCC Commissioner Ajit Pai – the first Commissioner to moderate a panel at the NAB Show – CBS Radio Senior Vice President of Engineering Glynn Walden told attendees that there was no sustainable future for analog AM broadcasting and that the FCC should set a date for an "for a digital AM sunrise and for an analog AM sunset."
Walden has been one of the broadcast industry’s point-people on HD Radio from the very beginning. He helped develop the system’s core technical design and specifications, co-founded the company from which iBiquity Digital Corporation was born, and was instrumental in lobbying the FCC to approve HD as the U.S. digital radio standard. With three HD patents to his name, Walden would like nothing more than to see his baby actually fly after languishing all these years.
