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?"
Liberate the specturm or you will suffer digital restrictions. Vista's checking of line voltages to make sure no one has clipped on an analog recording device should tell you where all of this is going. The RIAA has been screaming about "radio pirates" for 50 years. Digital broadcast gives them a way to close the "analog hole" they so dread. If the makers colude with broadcasters, only "authorized" players will have keys to decode "HD" signals. If the specturm is liberated, everything will be high quality because no one but big publishers wants to degrade music.
DMCA, Hollings, Palladium. What might have sounded like paranoia is now common sense.
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.
Please visit www.rush2112.net for an adapter and controller for the Visteon HD Radio car unit and the one from Directed Electronics.
It can be used with a number of satellite radio recorders like SatAmp to record broadcasts and timeshift. It also comes with a demo and development kit if you like that sort of thing.

I have his XM and Sirius adapters. They all work on the same principle by talking to a vehicle OEM tuner via the RS-232 port that they all have.

If you know of a solution, don't write it in this discussion!
Please be aware that not everyone who browses slashdot has our best interests at heart. Any commercial method to circumvent DRM will be jumped upon by our broadcast content overlords. Any non-commercial method will be legislated out of existence... the longer the media cartels remain in the dark, the longer we have to enjoy our right to timeshift content.
Like usenet... the first rule of usenet is that you don't talk about usenet.
Sorry for the pessimism and tinfoilhattery, but this entire ask slashdot question just screams "honeypot" to me, even if that wasn't its intent.

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

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/
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.
Tired of being "punished" by the Slashdot $rtbl since 2002. I'm now over at http://soylentnews.org/ .
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:
