FCC OKs Increase in HD Radio Power. Increased Interference Ahead?

On Friday the FCC’s Media Bureau quietly announced that it adopted an order to allow FM stations broadcasting a digital HD signal to increase their power levels up a maximum of 10% of the power of their main analog signal. While the National Association of Broadcasting and iBiquity have been agitating for this change for quite some time, it’s the backing of National Public Radio and its engineering report on the matter that was the likely tipping point.

But, as radio researcher John Anderson points out, this change is also likely to produce more interference complaints from listeners trying to tune in weaker stations adjacent to these higher power digital signals. There have already been significant complaints and concerns about digital HD signals interfering with adjacent analog stations with the previous power limit set at 1% of a station’s analog power.

The Prometheus Radio Project, in particular, questioned NPR’s support for the increase based on NPR’s own engineering data (PDF). Prometheus noted that listeners asked by NPR Labs to rate HD interference to analog signals at the new power levels gave the quality of the resulting audio a score of 2.7 on a 5 point scale, which is below a rating on “fair” on that scale. Prometheus further argued that,

The NPR Labs Study represents a “best case scenario” test of interference to analog. … Although the NPR Labs Study showed troubling levels of interference, the decision to use a single, highly selective receiver dramatically limited the extent to which these results can be extrapolated.

For its part, NPR responded to Prometheus and other critics [PDF], contending that they “generally misapprehend or ignore the [HD] testing methodology, the test results, or the results of NPR Labs’ prior [HD] testing.”

Radio at CES: Hype for HD Radio, but price is still the biggest barrier


HD Radio: Don't believe the hype

Like PE says: Don't believe the hype!

I keep reading all this hype about how HD Radio is the big audio deal at this year’s Consumer Electronics Show, yet I fail to quite see what’s so exciting. Sure, there are some new models of HD Radio receivers rolling out, but the number of new entries roughly equals the number of models being retired. The end result is that there will be about as many HD receivers on the market as last year. That’s big news?

I guess Ford announcing stronger support for HD and the new iTunes tagging features count for something. But where the rubber meets the road is whether car buyers are willing to pony up the extra cash for the higher-end stereos. While Ford is doing better than Chrysler and GM, the last time I checked, the auto industry isn’t exactly thriving. And let’s not forget that just few years ago the big hype was how the auto manufacturers were embracing satellite, yet that seems to have mostly resulted in lots of XM Sirius-equipped rental cars.

I keep searching for information about all these new non-automotive HD receivers and I keep coming up with the same iBiquity press release regurgitated all over the place. The release lists off a pile of model numbers, but no other info that might help me evaluate how great these new receivers might be.

iBiquity's CES News Page

According to iBiquity there is no CES 2010 news!

iBiquity set up a special page just for “breaking news” from CES 2010. But today, the next-to-last day of the show, there’s no news to be found.

Only This Week in Consumer Electronics has any useful information, including the most valuable data of all: price. Amongst the models listed by TWICE, at $69 the lowest cost receiver is Radio Shack’s FM-only Gigaware-branded add-on for the iPhone and iPod Touch. The price isn’t outrageous, and marks only a $10 – $20 premium over a typical FM-only radio for the iPhone. Past that, all of the new HD receivers come in over a hundred bucks. That includes even the entry from discount electronics brand Coby, whose HDR700 has a street price of around $99.

I really believe that price is the key here. With the collapse in the quality of commercial radio programming, HD Radio really has not been able to sell itself on programming, despite the largest broadcasters like CBS Radio blanketing their stations with ads touting HD’s virtues. The quality issue is also debatable. So, at best, I think HD Radio is still a curiosity for most people who might be attracted by having a few more channels at their disposal, or having AM news, traffic and weather on the FM HD channels. But what are people willing to pay for this curiosity?

Radio at CES: Pandora and tagging rolling out for your car

The biggest news at this year’s Consumer Electronics Show might be Google’s new Nexus smartphone, but that doesn’t mean there’s no space for radio in all the gadget frenzy. Your resident RadioSurvivors don’t yet have the travel budget to jet off to Vegas to roam the show floor in person. Instead, I’m picking through the press releases and news stories (which often are just rewritten press releases) from cold and snowy Chicago.

Although I am not a car owner myself (I traded my old Subaru for a new bike this year–no lie!) the automobile is still the site of much radio listening, and the realm of some interesting tech developments. Internet and iTunes tagging appear to be the radio stars this year, with satellite playing a supporting role. As one of our readers pointed out, Ford recently announced that it would offer a factory-installed HD Radio receiver that includes iTunes tagging. In addition the company said it’s working on integrating tagging with Sirius satellite radio, which will also feature the ability to record and playback up to 45 minutes of satellite audio. Shades of Apple’s “live-pause” in the new iPod Nano?

Pioneer's Pandora controlling receiver.

Sony also offers up a car HD receiver with iTunes tagging (CDX-GT700HD) and Pioneer offers up several new models with the same features. But their new top-end receiver (AVIC-X920BT) goes one better by adding support for Pandora. The catch is that you need an iPhone that connects via a USB cable. Once linked, then you can browse stations on the receiver’s 6.1″ display.

Alpine also takes the iPhone route to offer Pandora in your auto with its iDA-X305S receiver. No to be left out Ford promises Pandora integration along with Stitcher, which is apparently the news/talk yin to Pandora’s yang, and something I’d never heard of before. Yet again, Ford’s approach requires an intermediary, with SYNC project manager Julius Marchwicki promising,

in the future, if you bring Pandora or Stitcher into the car on your phone, it will work seamlessly.

Notable Comments on the RadioSurvivor Decade in Review

Readers comment on our decade review.

One of the most satisfying aspects of putting together our review of the decade’s most important radio trends was the number of comments we received. It appears we touched a nerve or two. And while not everyone agreed with our arguments or conclusions, we did get some thought provoking responses.

Seeing as how we like to encourage some rousing debate about radio, with this post I’d like to highlight a few of them.

Responding to #11, cash-strapped schools turn their backs on college radio, Seth Thornberry points out:

In another example of the spirit of independent radio, the DJs from KTXT got together and created The Llano Idea which has kept up the volunteer run radio (online, at least).

In response to #6, HD Radio launches, but who listens? Who cares? BrianK finds some hope for the service:

Ford announced today that HD Radio is factory installed in their autos and the at least 4X digital power increase for HD radio is on the cusp of being approved which will give listeners stereo reception upto twice as far as traditional auto FM receivers in noise-free and to my ears much better high frequency response

But Greg begs to differ, noting that,

Ford has been announcing that it would add HD Radio since 2007, but it never materialized. Also, Ford is an investor in iBiquity. … BMW even has an HD Radio trouble-shooting guide, and there are nothing but complaints about HD Radio in BMW Forums, so I’m guessing that it will be the same situation with Ford.

And Robert D Young Jr quips:

PS. just one little correction: CD quality is really “seedy” quality.

Wrapping up the decade in radio and looking forward to the decade ahead

Wrapping up our decade in review.


As I said in my introduction to our subjective and opinionated review of radio in the 2000s, I still think it was darn near impossible to predict how the medium of radio would end up at the beginning of 2010. Sure, the seeds for satellite radio, HD radio, low-power FM, internet radio and MP3s were already planted by the turn of the century. But home broadband–nevermind wireless or mobile–was a relatively exclusive luxury. MP3 players were lucky to sport enough memory to hold about a hundred minutes of music and weren’t integrated into cell phones. Satellites for Sirius and XM were launched, and HD Radio was being experimented with, but no stations were on the air. Clear Channel was flying high for more than $90 a share.

Anyone taking a broad view of the radio industry in 2000 could certainly see a lot of balls being thrust up into to the air, but it would have taken a psychic to predict where they would land. Nevertheless, for all of the churn we can say very safely that audio-focused content is alive and well.

It’s become clear to me that we Radio Survivors do consider radio to be greater than just the traditional electromagnetic broadcast medium. While we included the RF-based college radio, pubic radio, LPFM, HD Radio and satellite radio in our review, we also touched upon internet radio, Pandora and digital downloads. I believe we are first and foremost fans of terrestrial broadcast radio, but that does not cause us to ignore or discount new audio media. Nor does it cause it us to claim that they are not, in essence, radio services.

The homogenization and delocalization of the broadcast dial caused listeners to seek alternative places to hear more interesting and diverse content. At the same time the popularity of MP3 players and Pandora shows that people were also looking for customization.

The decade’s most important radio trends #6: HD Radio launches, but who listens? Who cares?

#6 in our series on radio trends of the decade


June 12, 2009 is a day that will live on in broadcast history. That’s the day that the nation’s television broadcasters switched off their analog signals and went all-digital forever more. But does anyone remember January 7, 2003?

That was the date of the very first digital HD Radio broadcast, originating at Detroit FM station WDMK. However, it isn’t clear that there was anyone in Detroit who could hear the digital signal besides employees of Radio One, the station’s owner, or Ibquity, the developer of HD Radio. The first consumer HD Radio receiver was actually sold two days earlier in Cedar Rapids, Iowa, and there’s no indication that the buyer then drove to Detroit.

That this date isn’t so well remembered is indicative of the collective shrug HD Radio has received from the American listening public over it’s seven years on the air.

Renamed HD Radio from the technical name IBOC (standing for the method of its broadcast – In-Band On Channel), the digital radio broadcast system was launched with the promise of offering static-free digital sound with higher fidelity, along with added subchannels adding more feeds of news, talk or music. Unlike digital TV, HD Radio would accomplish right on the AM and FM bands, by squeezing in an additional digital signal alongside a station’s required analog program.

By all accounts HD Radio works, though many critical listeners question whether digital means better. In order to squeeze the digital signal into the analog station’s space on the band it has be highly compressed. While broadcasters like to call it “CD quality” the primary channels are often broadcast at pretty low bitrates, especially when they have to share bandwidth with extra subchannels.

Renaming the system HD Radio smacks of opportunism meant to latch onto the appeal of high-definition TV. For its part Ibquity claims that any resemblance to true high-definition is coincidental. In early whitepapers the HD was said to stand for “Hybrid Digital,” though that meaning has long been dropped.

The most significant criticisms leveled at HD radio result from interference concerns. (more…)




AM on FM Begins Oct. 1

After rendering the AM dial a garbled mess after sunset by cramming in too many stations along with space-hogging HD signals, in 2007 the commercial radio industry came a-calling to the FCC with it’s hand out. It’s request? To let AM radio stations have repeater stations–called translators–on the FM dial.

While sitting on the NAB’s proposal for nearly two years, the Commission quietly let AM stations utilize FM translators that their parent companies already owned, provided they applied for what is known as “special temporary authority.” Then, this past July, the FCC made the policy official.

Those of us concerned that the rule would signal an influx of new commercial low-power stations eating up frequencies that might otherwise go to community LPFM stations were relieved. The Commission’s new rule essentially reflected its earlier shadow policy, only permitting AM stations to use already existing FM translators. The Commission also signaled that no new opportunities to obtain a commercial FM translator was imminent.

While I still think it’s bad policy, it could be a lot worse. Commercial translator owners now will have to make a choice as to whether it’s more valuable to repeat their AM or FM stations. Also, the same existing rules apply which limit commercial translator to being located only within its parent station’s broadcast area. This is because the commercial translator station’s purpose is to fill in areas where geographic or other anomalies hinder reception where otherwise one would be expected to receive a station. Noncommercial translators are not subject to this restriction, and may be located any distance away from parent stations. So, a commercial AM station’s new translator still has to be located in its protected broadcast radius.

As the CommLawBlog gleefully reminds us, this new policy kicks into affect on October 1. It will be interesting to see which, if any, AM stations take advantage of this opportunity, or if the rule sparks a spike in selling and exchanging FM translator licenses.




One of the Last “Progressive” Rockers Goes Digital-Only

When it comes to commercial radio, I’d argue that true progressive rock radio died somewhere in the early 80s, as tighter playlisting, more frequent rotations and shorter music sets became required, and DJs by-and-large no longer picked their records. Nevertheless a handfull of stations in the top major markets held onto the progressive moniker by keeping their rotations less repetitive, being a tad bit more experimental with the songs they added andretaining DJs who seem to know and care about the music, all while giving a more believable appearance of artistic integrity.

For rock music fans over the age of 30 the call letters are often drilled into memory: WNEW in New York, WMMS in Cleveland, KSAN in San Francisco, WBCN in Boston and WXRT in Chicago. At the beginning of 2009 only WBCN and WXRT remained on air in a form with any semblance to their former glory. As of last Thursday WBCN had joined the off-air list.

Well, it’s not entirely accurate to say that WBCN has gone off-air. While the station’s analog signal at 104.5 FM has been replaced with an all-sports format, the rock station has found a new home on a digital-only 98.5 FM HD channel 2 along with retaining its webcast.

As recent press reports on the station’s move–which read like obituaries–tirelessly note, WBCN was the first station in the US to play a once obscure little band from Ireland called U2, along with pioneering the introduction of many former “alternative” rock bands on commercial radio, like the Red Hot Chili Peppers and Pearl Jam. Of course, the station was much more progressive during album rock’s heyday in the late 60s and early 70s, when such future rock luminaries as J. Geils Band’s Peter Wolf did DJ stints.
