HD Radio Recording In the US?
unreceivedpacket writes "The public radio stations I listen to have been advertising their conversion to HD Radio format for some time. They advertise multiple channels, their second channel playing all classical, all the time. I am interested in purchasing a receiver so I can listen to this extra content, and was also hoping to find a receiver with a built-in recorder so I could time-shift programs that are not otherwise available as legal pod-casts. My initial queries have returned few models that support any kind of digital recording, and the existing ones seem out of production or sorely lacking features. Is this the state of Digital Radio in the US? Are there any legal recording devices for HD Radio? Any good solutions for recording and time-shifting, perhaps through Linux?"
Satellite Radio is a much better choice for this than the joke that is HD Radio.
The Sirius Stiletto 2 is a great little radio, with full time-shifting capabilities.
Cambridge Soundworks makes a model with optical digital outputs. No clue if there are any restrictions on them, though. On a higher end, Yamaha makes several AV receivers that handle HD as well. Again I have no knowledge whether or not the digital outputs are crippled in any way.

A simple Amazon search turned up quite a few models. Some have optical out. One has an iPod dock.

Really, I just listen to HD streaming radio these days. Specifically, WCPE (classical music) and NPR Boston both publish in OGG Vorbis, which is great.

There are a lot of others, but Chumby does that and a lot more.
The HD in HD radio does not stand for High Definition.
"According to iBiquity, the name "HD Radio" is simply iBiquity's brand for its digital radio technology,[6] and does not stand for "Hybrid Digital" or "High Definition" such as HDTV does."

I don't think DRM is an issue. I suspect that the problem you're having is due to HD Radio being a new technology. There is a fairly widely used analog technology called Subsidiary Carrier Audio that is used to transmit background music and similar stuff over FM stations piggybacked on the primary signal. The background music in your local supermarket is probably SCA. Since stations presumably can't do both SCA and HD Radio, the number of stations that can actually deploy HD Radio is limited. Not too many stations means not too much HD Radio equipment. OTOH, maybe HD Radio will catch on. I'm told that HD Radio fidelity is nothing to write home about, so maybe simply feeding your radio's speaker output into the microphone input to your sound card will work until more diverse HD radio equipment becomes available.

On the point of streaming radio, some of us broadcasters are struggling to meet the regulations, you can hear our listener-supported, progressive radio station at the listen live link at the top of the page for WTUL New Orleans
...and it should be known by now
All XM's music channels are commercial-free; their other channels are not. I believe Sirius has a similar policy.

HD Radio/IBOC jams on both AM and FM and suffers from dropouts, poor coverage, interference, bland programming, and almost zero consumer interest: http://hdradiofarce.blogspot.com/
What's replacing radio?
Not sure. But something certainly is:
Radio's Popularity Declining Unevenly
CBS Acquires Last.fm Seeking To Overcome Declining Radio Business
In decline: TV, radio, newspapers, books, mags

These new HD stations are being broadcast right now. I live in fly-over country in Wichita,KS and we have about 10 up and going. So I would think those of you in the Big cities would have many more. They are just a subset of the existing channel. They are just being broadcast on a digital signal. They are FREE and use advert. as current ones do. Just be careful of the new ACTA internaional treaty http://www.publicknowledge.org/node/1656 since the Sony's of the world want to shut down the ANALOG plugs on the back of your receivers so you cant even record ANYTHING even in Analog.
What's the issue? The first page of a Google search for "hd radio output jack" lists
HD Pulse with "Stereo Output"
Sony XDR with 3.5mm stereo output jack
JVC KT-HDP with a stereo out
Just plug the line out to your recording device of choice (digital or otherwise) and go to town.

If by 'these days' you mean the past eight hundred years in common law legal systems (the US, and England before it), then maybe your argument that nobody owns property without paying the government is a good one.
Yeah, no experience at all. But yeah, that you can pass two light beams through each other and emerge without loss of signal shows that the "radio interference story" the public has been fed is a lie.
But RF isn't visible light spectrum. And if interference really was a lie, why hasn't anyone created a receiver that is totally insusceptible to interference in 100 years of radio engineering? And if this was possible, technically it should be possible to receive and demodulate any signal at any level infinitely less than the noise floor. I'm not a physicist, but I'm sure there are people way smarter than me who would have done it already, because they'd be obscenely rich right now.
The over-simplified wrong answer that is open spectrum is painful obvious when you see statements like this:
28. Does this require everyone to get new radios and TV sets?
No. Existing technologies will continue to work. They will be replaced by customers as they â" we â" realize the benefits of the new technology.
Implementing open spectrum would immediately put any existing services into danger because it's the "new technology" that would enable open spectrum. Legacy technology wouldn't be able to participate in such an environment and would be susceptible to interference. Of course for people believing interference is a big lie, it's hard to grasp the concept.

Let me rephrase my previous post. While you can pass two beams of light through each other, and you can pass two radio spectrum waves through each other, this is totally irrelevant to radio interference. Beam the two waves, whether visible light or radio spectrum into a receiver and while they can add and subtract, they can destroy information to the point where the intelligence can't be extracted. If you take the simplest model of a carrier modulated with intelligence by turning it on and off, one can create a interfering signal that is turned on when the intended signal is turned off. Match the phase and amplitude perfectly and no technology in the world will extract the signal, hence interference.
To say that interference is a big lie is an outrageously simple and wrong conclusion.

You obviously don't listen to a radio station that's paid for the HD Radio technology. KDFC advertises HD radios a lot. (Then again KDFC also has too much gab and not enough music, and it's all very "pop" classical and not so much serious works of more than a minute or three, and... general lame :P i've switched mostly to the jazz station in the mornings)
The World Wide Web is dying. Soon, we shall have only the Internet.
XM has six music channels programmed by Clear Channel that play a small ammount of ad content per hour. When these formerly ad-free channels went commerical, XM countered by adding a replacement similarly-formatted channel (XM Hitlist to challenge Kiss-XM, for example) that is commerical free.
There's also several CC-owned talk channels that mostly air Premire Radio Networks talk shows like Talk Radio, America's Talk, America Right. These play commericals in every minute that their format allows, with a small handful of PSAs taking up what isn't sold.
Other than that, XM's music channels are commerical free, and the advertising are so infrequent on talk stations that XM has a library of content produced for to fill the gaps in syndicated programs, and when talkers on a commerical free station like POTUS '08 need to regroup. A good chunk of the ad time on those channels go to telling listeners what's going on elsewhere on the XM service.
The Sangean someone linked to earlier has TOSlink out.

I'm a broadcast radio engineer. i'm a tad biased, so to speak:
1. A privately held codec has no place on the public spectrum. Any hobbyist should be able to build a receiver without paying a license fee.
2. from an operational standpoint it's death to AM at night. First adjacent channels (ie 1000khz & 1010khz) HD's will interfere with analog signals via skip: listening to distant AM signals (DX'ing) at night will be a thing of the past, especially as solar activity increases over the next 5 years.
3. We as broadcasters have failed to provide meaningful content on the main signals, and now we're polluting media channels with bad content and no revenue. We've failed to promote hd in any meaningful way. The only clear winner is not the broadcaster nor the listener, but the ibiquity corporation.
the actual question?
i don't believe it does HD, but the radioshark is a analog device which does what you're looking for:

EM does not "interfere" with itself, it adds just as light does.
Except that, y'know, light interferes with itself too.
