As lobbying over the conditions of the merger between the Sirius and XM satellite radio networks entered the home stretch, iBiquity Corporation and the National Association of Broadcasters requested that the Federal Communications Commission mandate all future satellite radio receivers to be interoperable with terrestrial digital AM and FM broadcasts.
This was a move by HD Radio‘s proponents to try and get something for nothing. XM and Sirius both subsidized the adoption of satellite radio receivers, especially in vehicles, by making the reception technology freely available and offering special deals to new subscribers (such as free service for a year or more, especially for folks who bought new cars and trucks with a satellite radio receiver as an option). In contrast, iBiquity Corporation wants those who make and market HD radio to pay it a cut from every HD receiver sold – effectively asking auto companies to partially pay the way for HD’s adoption. This is a proposal that nearly all have resisted. Continue reading “Sirius/XM Merger Sidebar”

XM/Sirius Merger Hinged on Piracy Compliance
After a week-long, non-transparent deliberation, the Federal Communications Commission has reportedly signed off on the merger of the XM and Sirius satellite radio networks.
Many of the tea leaf-readers did not correctly forecast the outcome: most expected at least one Democratic Commissioner, Jonathan Adelstein, would vote for the merger, provided there were certain public interest obligations on the new, singular satellite broadcast entity. These would have included requirements such as a percentage of total satellite radio capacity be devoted to non-commercial, possibly public-access channels, and that the new company provide tiers of service that do not gouge existing and future subscribers. Some of these conditions will apply to the merged company, but the Commissioners’ votes themselves ultimately split along party lines. Continue reading “XM/Sirius Merger Hinged on Piracy Compliance”
Digital Radio Wobbles Around the World
Last month, I attended an exploratory workshop hosted by the European Science Foundation about the prospects of community media in a digitally-convergent communications environment. Not surprisingly, when one thinks “community media,” radio first comes to mind, and we represented in full: most of the 30 invitees to this workshop were either involved in radio activism and/or regulation in their respective home countries.
My personal mission was to warn as many other countries away from casting their fates with iBiquity’s HD Radio platform, as it not only carries a plethora of technical risks, but it may 
decimate community radio stations as we know them (draft, not for publication). Fortunately, this was an easy job: the Europeans can see through the snake-oil that is HD Radio, and the general consensus of the workshop was that HD should be opposed at every step.

FCC to Consider Raising FM-HD Power Levels
Documents were filed with the agency late last week by HD Radio’s proprietor, iBiquity Digital Corporation, to allow FM-HD stations to increase the power of their digital sidebands by a factor of 10. The rationale behind this request is increasing field evidence which shows that the digital portion of FM-HD signals fails miserably at matching increasing analog signal coverage, and the existing power level does not allow digital signals to penetrate buildings very well.
This proposal does not come without risk; evidence of HD signals interfering with other stations is already well-known, especially on the AM side, and the Corporation for Public Broadcasting has completed a study that adds new information to the body of knowledge regarding FM-HD interference. Unfortunately, the results of this study have not yet been made public, though notably National Public Radio itself has not taken a position on whether or not increasing the digital output of FM stations is a good idea.

Interesting Notes of Miscellany
Sporadic news-updates will continue for the next month and a half, as I tackle my last preliminary exam. But the rest of the site is current (save for a batch-check of the links library for broken stuff). So, in the meantime here are some updates on a few of my favorite things:
HD Radio: Industry skepticism of and resistance to the technology is growing. Oppositional broadcast engineers, who used to be considered on the “fringes” are now getting at least a semblance of respect in the trades dialogue. Much of this has to do with the real-world impact of HD-related interference, most notable now on the AM band but soon coming to an FM dial near you, especially when stations are given permission to boost the power of their digital sidebands (at the expense of analog signal quality). Results of an HD signal-related interference analysis commissioned by the Corporation for Public Broadcasting – the first of its kind to really go into detail about FM-HD-related interference – should have been released by now, but hasn’t yet.

HD Interference: Not Just For AM Anymore
Radio World Engineering Extra dropped a bomb this month with a very provocative cover story: “What Are We Doing to Ourselves, Exactly?” Written by Doug Vernier, the man who authored the technical specifications for an ongoing Corporation for Public Broadcasting-sponsored HD Radio interference analysis, the report is the first of its kind to document interference between FM-HD stations around the country.
Using anecdotal reportage, some sophisticated contour-mapping, and presumably “early data” from the CPB study, Vernier’s article conclusively proves how stations running in hybrid HD/analog mode can (and do) interfere somewhat significantly with not only themselves, but their neighbors on the FM dial.
Most interesting tidbits: Continue reading “HD Interference: Not Just For AM Anymore”
The FCC's Three Ring Circus
That’s what I get for taking a month-long hiatus: the FCC goes all P.T. Barnum on our ass, in hopes of making suckers of us all.
In the center ring is the agency’s proposed changes to media ownership regulations. After hinting that he wished to ram through major changes allowing broad consolidation by the end of the year, and hustling to finish public hearings on the subject over the last month, FCC Chairman Kevin Martin – in a highly unusual move – published his own proposal to modify only the regulation that restricts cross-ownership of newspapers and broadcast stations in a single market. Unfortunately, as noted by the minority Commissioners, this proposed change contains loopholes that would effectively do away with the cross-ownership ban, while keeping its regulatory shell on the books. This has irked members of Congress, many of whom are threatening to legislatively intervene if the FCC moves on any media ownership rule changes before the end of the year.

Growing Resistance to HD Radio
After feeling like I’ve been shouting into the wind alone for so long about this, it’s great to see others taking a critical perspective on HD’s fundamental flaws. Check the following blogs for lots of information about this tainted technology, especially since these folks are also doing an excellent job aggregating news coverage of the issue:
Is HD Radio a Farce? – A good collection of information on what’s happening both within the radio industry and among consumers, who, by and large, seem to be holding their noses once they get a whiff of those “secret stations between frequencies.”
HD Radio on the Medium Wave (AM) Band – An excellent, if somewhat disorganized, collection of coverage about the increasing problems with AM-HD interference. Continue reading “Growing Resistance to HD Radio”
AM Broadcasters Back Away from HD Deployment
According to a leaked memorandum from ABC/Citadel‘s executive chief engineer, all AM stations in the company’s stable have ceased broadcasting in digital at night, effective immediately. The memorandum does not give specifics, but follow-on reports cite interference between AM stations on adjacent channels as a major factor for the decision. Interestingly, some suggest Citadel executives knew such a problem might be in the offing, but they went ahead and turned on their digital signals at night anyway.
This is a major setback for the adoption of HD Radio, especially on the AM dial, and Citadel is the first large broadcast conglomerate to back away from full deployment of the HD broadcast technology. Although the company’s gone out of its way not to characterize its move an indictment of iBiquity’s proprietary digital broadcast standard, the problems with AM HD broadcast interference are well–known and -documented.

Alternatives to HD Radio
Believe it or not, “HD Radio” is not the only digital audio broadcast system in the world. Alternatives do exist: one of the most promising is Digital Radio Mondiale (DRM) (which should not be confused with “digital rights management,” a whole other (evil) animal), which has been jointly developed and deployed by some 30 countries around the world. It’s an open-source standard, which has the potential to operate on either new or incumbent spectrum, and contains the potential to practically advance the service terrestrial broadcasting provides; it is not just a “better than analog” standard, featuring chimerical vaporware such as “buy buttons” for the download of digital music – services for which radio was not initially designed.
At present, while Digital Radio Mondiale is gaining traction around the world, it’s all but been ruled out as a potential alternative to HD Radio in the United States, though that may be changing. A coalition of spectrum experts has been formed to advance the notion that broadcasters should be afforded the choice of picking between HD and DRM. As of now, this advocacy is restricted toward the possible deployment of Digital Radio Mondiale on the shortwave and AM bands only; although an FM version of the technology is under development, HD’s relatively slow but steady adoption by U.S. FM broadcasters may make it a tough sell in the marketplace (even though some transmitter manufacturers are making dual-compatible HD/DRM transmitters, and there’s no reason why receiver manufacturers couldn’t follow suit).
