Not yet. All the ATSC tuner chips went into TVs and the DTV converter
boxes. Now that conversion to digital is done there should be lots of
chips available to vendors to make AM/FM radios with TV sound.
The current ATSC chips use much more power than the NTSC chips so the
battery life of new "TV radios" are not going to be near as good as the
old ones (the Sony Walkman I had lasted over 25 hours on two AA
batteries). Hopefully, there will be new chip sets developed that will
give them much better battery life.

OK
I guess the new HD Radios available now can NOT receive
the TV channels?

Correct. HD Radio is only AM and FM stations. The HD stands for a
variety of things (depending on who says it). Some HD RADIO stations say
it stands for Hybrid Digital, other say it means nothing (just letters
to distinguish it from analog). When it first came out it was called
Hybrid Digital (HD) Radio.

Understood thanks!
Seems like since everything is going digital.... radio
and TV, etc..... it would be simple to build a desktop
radio that would allow listening to ALL. No?
Am I missing some tech reason why its not that easy to
do?

I think the manufacturers are waiting for the low power chipsets.
Almost all radios made are portables.

Remember, "High Definition" does *not* imply digital. Especially
when you're listening to ads for "High Definition Laser Vision
Correction", which I have heard a number of times on non-HD radio.

If they are saying that, they shouldn't be. Tell them to look
at the materials they've received from iBiquity.

I used to also believe that HD meant Hybrid Digital. At least that would have
made sense. But Ibiquity, who invented the format, says it means nothing. See
page 29 of this PDF file: http://tinyurl.com/mv4x9c
If it means nothing, then the letters HD were obviously chosen to create the
impression of "high definition", which is not true of the format. But I have
heard stations claim on the air that they were broadcasting in "high
definition" digital sound.

Oh yeah, I'm sure that's exactly what iBiquity wanted people to think.

No its not the same as the HD in HDTV!!!!!
http://en.wikipedia.org/wiki/HD_Radio
"The FCC has not indicated any intent to force off analog radio broadcasts as
it has with analog television broadcasts, as it would not result in the
recovery of any radio spectrum rights which could be sold. Thus, there is no
deadline by which consumers must buy an HD Radio receiver."
The broadcasting industry is seeking FCC approval for conditional access, that
is, enabling the extra programs to be available only by paid subscription (on
future models of HD Radio). Conditional access will also enable special
services for the blind (such as radio reading services) and hearing
impaired.[31] NDS, a maker of digital media encryption technology, has a deal
with iBiquity to provide HD Radio with an encrypted content-delivery system
called RadioGuard.[32] NDS claims that RadioGuard will "provide additional
revenue-generating possibilities".
So go right ahead and buy a HD Radio, when this Radio guard tech is
implemented , it will make any subchannels unreceivable if you have an older
HD Radio.

According to the company that invented it, "HD" stands for neither
of those phrases:
http://www.ibiquity.com/press_room/fast_facts/trademark_guidelines
Although I have seen reports that iBiquity was using the phrase
"hybrid digital" at some point in the past. And it's pretty obvious
that they *want* people to think that it means "high definition."

They can say not to use the term hybrid Digital al lthey want, but that is
exactly what it is. iBiquity is just wanting to ride the confusion coattails
of the HDTV people.

I have even heard the reference to "high definition" while listening to a
station on analog FM (i.e., not using an HD Radio). At some point the
station will say something like "broadcasting in high definition".
It may not be technically correct by the iBiquity guidelines, but even so it
is clear that more than one station is definitely using HD to mean "high
definition" even if their broadcast may not necessarily be a high definition
broadcast.

I also just recently heard one station refer to their broadcast as "high
fidelity" rather than "high definition", so maybe someone out there is
de-facto policing the use of "high definition" when referring to radio.
