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.

HD Radio: By the (Disputed) Numbers
The Pew Research Center’s Project for Excellence in Journalism has released its annual State of the Media report, and it does not have kind words for radio. It laments the decimation of radio journalism and documents how other digital audio platforms are gaining traction at the expense of broadcasters. It also minces no words about the state of HD Radio:
AM/FM’s beleaguered attempt to draw people back to radio through HD did worse than ever. For the first time since 2004, when HD radio receivers became available for retail sale, more radio stations dropped their HD signal [in 2012] than adopted the technology.
The entire mention of HD is just two paragraphs, and includes a graph illustrating the net decline in the number of HD stations on the air.
The technology’s proprietor, iBiquity Digital Corporation, was quick to pounce on the "error" of Pew’s analysis. iBiquity CEO Bob Struble claims there was a "net gain" of 16 HD stations in 2012. Continue reading “HD Radio: By the (Disputed) Numbers”
Radio's Imminent Demise in the Dashboard?
Radio Ink publisher Eric Rhoads penned a frantic and strident report following the magazine’s annual ConVergence Radio Conference earlier this month in which he warns of radio’s impending extinction in vehicles.
On the stage were three representatives of the automotive industry: one from Gartner Research…one from the Silicon Valley offices of General Motors…and one who represents an industry association for the connected car. They were on a panel moderated by Buzz Knight of Greater Media, and they talked about the direction of in-car experiences, the digital dashboard, and what will be coming next to the dash of the car….Then, suddenly, this statement was heard: Continue reading “Radio's Imminent Demise in the Dashboard?”
HD Radio's Multifaceted Search for Traction
We’re going into HD Radio‘s 11th year on the air. So far, the technology’s proliferation has been underwhelming, to put it mildly. However, proponents of HD are working on several projects which they hope will break it into the mainstream. They are: Continue reading “HD Radio's Multifaceted Search for Traction”
All-Digital AM-HD Tests Underway
Proponents of revitalizing the AM band using HD Radio are now testing the all-digital signal in the wild.
The guinea-pig is WBCN 1660 – a CBS-owned station in Charlotte, North Carolina. Currently a satellite-fed conservative talk station, WBCN will switch to a satellite-fed sports talk format in the new year. In a market of some two dozen stations, WBCN ranks 20th.

HD Radio's Latest "Killer App" Isn't Radio
Radio World has awarded Paul Brenner its 2012 Excellence in Engineering award. Brenner, the senior VP and chief technology officer for Indianapolis-based Emmis Communications, has been the industry’s latest point-person regarding innovations involving HD Radio. He’s led the development of a prototype smartphone with FM-HD reception capability as well as an application that melds radio reception with “value-added” content delivered over the cellular network.
Brenner’s also president of the Broadcaster Traffic Consortium – an alliance of some two dozen radio companies who, along with NPR, are exploring ways to use digital radio signals to deliver real-time traffic information. Brenner estimates that there are about 12 million navigation devices in use that utilize radio to receive traffic data, and that figure’s growing by about 1-2 million per year.

Diverging Perspectives on the Future of AM
Nobody really quite knows what the National Association of Broadcasters’ AM Task Force is up to, but speculation surrounding their work has sparked some interesting discussion about the state and future of the oldest of the broadcast radio bands.
The Task Force seems to be considering two primary ideas for “revitalizing” AM broadcasting. One is to phase it out completely and migrate all AM stations to new spots on the FM dial. The other involves a wholesale conversion of AM broadcasting from analog to digital, using AM-HD as the mechanism. Continue reading “Diverging Perspectives on the Future of AM”
CEA Throws iBiquity a Bone?
One of the factors that’s hindering the proliferation of digital radio broadcasting in the United States is the reluctance of consumer electronics manufacturers to actually commit to making HD Radio-compatible receivers. Stand-alone receivers are nearly impossible to find in stores; only one portable model currently exists; and auto manufacturers are not exactly racing to embrace the technology.
This reluctance has been well-reflected in digital radio policy discourse. The Consumer Electronics Association, the trade group that represents receiver-manufacturers, has been critical of HD Radio for more than a decade now. Early on in the FCC’s deliberations over digital radio, CEA backed a standard that would have created a new-spectrum digital radio service; it was highly skeptical that HD would work as promised and was not happy with its wholly proprietary nature.

ZoneCasting Prepares Further Field Trials, Eyes Official Launch
Radio World reports that GeoBroadcast Solutions, the company behind “ZoneCasting” technology, will commence long-term field trials on a station in southeast Florida this fall and is preparing for a “commercial launch” as of now left undefined.
[For those just tuning in, ZoneCasting uses FM booster stations to break up a full-power station’s primary coverage area into “zones,” each one covered by its own booster. This allows the parent station to program each zone separately, offering geo-targeted advertisements, news, community information, and emergency messages.] Continue reading “ZoneCasting Prepares Further Field Trials, Eyes Official Launch”
LPFM vs. HD Radio: The Curious Case of KGIG
At the turn of the twenty-first century, proponents of HD Radio sold the technology to the FCC by claiming that it used “no new spectrum.” Advocates of low-power FM (LPFM) radio made a spirited but ultimately unsuccessful challenge to this claim. They worried that the digital sidebands of FM-HD signals would interfere with the new wave of community stations the FCC was preparing to unleash. HD supporters dismissed these concerns.
Ten years after both HD and LPFM took to the air, the conflict between the two services is crystal clear.
Brad Johnson is a lot like me: a former participant in the corporate media who made the decision to step away from it following the passage of the Telecommunications Act of 1996. One of the careers decimated by post-Telecom radio consolidation was broadcast engineering – Brad was the chief engineer at several Citadel and Clear Channel-owned stations in central California until he was let go in the repeated rounds of downsizing the companies conducted during their station-buying frenzy.
