"HDRadio"
Until now, portable HDRadioreceivers have been unavailable because
the chipsets needed by this technology required too much power to be
practical for a battery-operated device. However, in January 2008 at
the Consumer Electronics Show (CES) in Las Vegas iBiquity unveiled a
prototype of a new iPod-sized portable receiver. It is based on a new
chipset developed by Samsung. Although portable, it is still a
relatively power-hungry device (it will run on an average set of
alkaline batteries in about two hours, according to an iBiquity
engineer). But Samsung engineers at CES say a second-generation
chipset due in 2009 will be about 40 percent more power efficient and
then a third-generation chipset due about a year later will use even
less energy. According to iBiquity, Sony and others have expressed an
interest in using the first-generation chipset and that the first
portable HD Radios could be on the retail market in the USA as early
as Christmas 2008."

Let me get this straight, Eduardo - the current "new" Samsung chipset
has a battery life of only 2 hours, and the next-gen chip, due out in
2009, will be 40% more efficient - that leaves about 3 hours of
battery life. DAB radios in the UK (DAB now defunct) have a bettery
life of 10 to 16 hours. Let's see - my little Sony ICF-S10MK2 analog
pocket-radio, will probably go 200+ hours on two "AA" batteries. Lots-
of-luck!
IBOCcrock,
In reality the 'portable' HD-Radiowill be part of the Third Wave
of HD-Radiodeployment and adoption.
The First Wave - Presently there are first and second
generation HD-Radios for the Home; and these Home
HD-Radios do not have Power as an identifiable issue :
Because they run-off of the House's AC Power {Mains}
as their Source of Energy.
The ReallyAllImportant "The Second Wave" will be the
BIG ADVANCEMENT toward the Earily Adoption of
HD-Radio: Will come in the placement of HD-Radios
in Cars and Trucks. *Again like in the Home the Power
Source is not and identifiable issue with HD-Radioin
the Automobile; since the HD-Radioruns-off the Car's
self-charging 12 Volt DC Systems.
NOTE - A Rental Car with and HD-Radioin it Exposes 50
or moreRadioListeners to HD-Radioeach year. *Allow
them to Experience HD-Radiofor themselves.
IMHO - The History of HD-Radiowill follow the path of
FMRadiobecoming 'intergrated' over time into the now
"Ubiquitous" AM/FMRadio.
Sometime In-the-Future and That-Time-Will-Come !
When the FCC Issues Rules and Regulations that
Mandates thatAllNew Radios will be fully Digital
"AllMode"AM/FM/DSRadios
-aka-AllDigital IBOC "HD" AM/FMRadiowith Direct
Satellite (DS) Plug-and-Play.
Once that FCC Requirement happens DigitalRadio
Broadcasting will be "The Standard" in the USA within
Five Years after it's implementation.

"Is HDRadioToast?"
"There are serious issues of coverage. Early adopters who bought HD
radios report serious drop-outs, poor coverage, and interference. The
engineers of Ibiquity may argue otherwise and defend the system, but
the industry has a serious PR problem with the very people we need to
get the word out on HD... In other words, everything you can find on
the regular FM dial... The word has already gotten out about HDRadio.
People who have already bought an HDRadioare telling others of their
experience (mostly bad) and no amount of marketing will reverse this."

IBOCcrock,
Kicking up the Power of the FM "HD" Radio Signal from the
present 1% of the Analog ERP will solve 95.45% of the
problems that you have 'cited' for those FM Radio Listeners
living within the 60 dBu (1 µV/M) Service Contour of any 'local'
FM "HD" Radio Station. -
http://www.lpfm.ws/interference/
IBOC Intergration {Mixture} Stated as a Percentage of the
Analog FM Radio Stations Effective Radiated Power (ERP) :
Phase One Base-Line ~ Presently @ 1% of Analog ERP
Phase Two Step-Up ~ To 3% of the former Analog ERP
Phase Three Step-Up ~ To 9% of the former Analog ERP
