Unless they figure out how to get HD2 channels to work in a moving car
there will be no viability.

FM HD2 channels work fine in moving cars, and the signals are stable out
to about the 64 dbu contour....

Dream on.

Between us all here, there are about 25 HD car radios in use... some in use
for about 4 years. All incidents of dropouts on HD 2 channels are outside
the 64 dbu contour (using a Longley-Rice projection, of course).- Hide quoted text -

"HD Radio: Still low in priority at stores"

"I visited a Best Buy the other day, and while I was there I stopped
in the auto sound department. He took me to the display wall and
showed me the one unit that had HD Radio built in. It was a model from
JVC. He said that others were HD Radio ready, but they all required an
expensive interface to add HD Radio."

"Is HD Radio going to be killed by manufacturers' desire to keep it a
premium-priced upgrade?"

"I just embarked on my twice-per-year online shopping trip to see if
it's time to upgrade my car stereo to HD. Saw a sudden shift to car
radios now being 'HD-Ready' instead of HD for a number of radios. This
appears to require the purchase and professional installation of a
separate, compatible unit.

- Anyone know why this appears to be a sudden
- new direction

D'Oh ! No.

and what this might mean for the future of HD radio?"

But about 95% of measured listening occurs inside the 64 dbu contour,
and
80% is inside the 70 dbu contour.

As defined by the ability of HD to perform at all. A self fulfilling
outcome.


I should have been clearer... 95% of analog FM listening is inside the
64 dbu contour.

How do you know this? How do you define listening? PPMs that pick up
the radio behind the counter when you buy a pack of smokes? The radio
in the taxi?

The last time I looked the FM radio in my car didn't have the ability to
differentiate which side of the 64 dBu coverage line it was on.


I remember 64 dBu as a TV term. In radio it was 60 dBu (aka 1 mV/m; aka
Grade B Contour). Perhaps it has since been modified, as I retired from
radio about 20 years ago (when people stopped "listening").

Listeners can differentiate, quite obviously, between signals that come in
nicely and those that don't. Of course, depending on the actual location and
type of radio, what we see is that listening becomes less and less common
(even when indexed against population density) the farther you go from the
transmitter. Once you get outside the 70 dbu contour, listening falls to
nearly nothing approaching the zone around the 64 dbu. It's a question of
listening density, indicating that listeners will not go to the trouble as
the signal gets weaker, particularly if they have other options.

You live right under the transmitters. Most people live in the suburbs.

I live in Glendale, and the only nearby transmitters are KXOL, KROQ and
KLAX.

We know it after several different parties analyzed literally millions of
Arbitron diaries over a multi-year period. Diaries include the home and work
ZIP code, and since 70% of listening occurs in those two locations, it's a
perfect base. Diary ZIP code returns by station were laid over maps of
coverage and the results tabulated... and we got the figures cited.

This analysis, also done separately by Arbitron internally, resulted in both
the AM and FM signal based crediting system for stations or shows available
on more than one station in a general area; Arbitron's ascription process
first uses best signal to make a decision, and if neither station available
has a good signal, a random number generator determines who gets credit. But
the base here is the same study... where is each station listenable under
normal circumstances.

You are right under Mt. Wilson.

So is most of the LA market.

Maybe half of it. Mt. Wilson is irrelevant in many of the larger
suburbs, like Simi Valley f'rinstance.
