Well, I was bored and curious...so if you've been wondering what's
inside this (or probably almost any other) HD Radio tuner, here it is:

(warning: the following link contains large quantities of pictures and
is therefore not friendly to those who have bandwidth caps or are
charged on a "quantity of data transferred" basis)

http://greyghost.mooo.com/hdtunetakeapart/

It's not quite finished yet, some items need more explanation. I haven't
verified the clock rate of the DSP but believe it to be correct. I also
need to upload the larger photos and add the navigation links to the
page. But for those who are curious, it ought to do for now.

No tuners were harmed in the making of this page or in the exploration.
By the way, I have been completely unimpressed by the performance of
this tuner. (I'm so glad I paid nowhere near the retail price!) I'd
recommend you look at something else if you want to listen to HD radio.

My local BB has sold the tuner for $70 compared to the normal $99.
I have been thinking of buying one for some time, what are your
complaints and do you have a recommendation for a better unit?

Hi!

> What is HD radio?

HD Radio is the digital radio broadcast standard in the US. It's a
development from a company known as iBiquity. iBiquity primarily
functions as a licensor of the technology to others.

HD Radio broadcasts are delivered alongside the current analog AM or FM
broadcasts, and on the same frequencies.

Outside of the US, other methods are used, such as Digital Audio
Broadcasting (DAB) or Digital Radio Mondiale (DRM).

I think they might be coming to the realization that perhaps the units
aren't selling all that well. In my travels to Best Buy, I've never seen
anyone buying one, nor have I seen anyone looking at the demonstrator
unit on the shelf.

I bought mine from a liquidator for $30 as a scratch and dent item. It
has a few scratches and one minor dent, so I was not disappointed. ;-)

It's (very) cheaply made. I also wrote a product review which I will be
posting this afternoon. I'll post a link when I do.

But for now, and outside of the cheapness, I'd have to say that its
tuner section is deaf in terms of sensitivity. It can't even pick up
analog stations that numerous other radios in the vicinity (including a
cheap boombox and a clock radio) had no problem receiving.

All of these stations are no more than 30-35 miles from my location, and
many are closer. I moved my testing upstairs to see if it would produce
any improvement and it did not.

Later, when I moved it to its final location, I noticed that whenever
the NS-HDTUNE was powered, it caused a lot of interference with the FM
tuner on the stereo receiver I intended to use it with. If that's the
way things are, I'll just use the tuner in the receiver. It's a much
better tuner anyway.

I was using a Radio Shack powered AM/FM indoor antenna with the unit,
and that same antenna works well with assorted stereo receivers.

Sony is the only other company I know to be offering a standalone HD
Radio tuner. I have not tried theirs yet, as I haven't seen it offered
for sale other than online.
