New HD chip still way too power-hungry

"HD Radio"

"Until now, portable HD Radio receivers 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)."

"Sirius Satellite Radio"

"Sirius Stiletto 100 - the first portable Sirius radio that allows subscribers to listen to live Sirius programming... The unit's batteries give the user approximately 30 hours of life."

So much for HD in portable devices. Struble wants to increase battery life from 2 to 24 hours, which would be an increase of 1200%, and it still wouldn't match that of Satellite Radio's portable receiver.
 
Ohh can't wait to get one of these 2 hours, man! We're going backwards, the old tube portable radio's battery's lasted longer than that.

Gee, My GE Superradio gets several months from a set of alkaline D Cells. Sounds great in wideband AM on SOME AM stations (the ones which still transmit full 10 kHz audio)...

Yeah I have two of them, a Super Radio and a Super Radio II, the battery's last forever. They do sound good too.
 
Two hours? ???

The iBiquity bunny must be smilin' now. ::)

I'm not sure if Struble is smiling, now that the dirty little secret is out about the two-hour battery life. The SiPort chip was supposed to be out the end of last year, but it never materialized. Look at this hoopla from the Samsung folks:

"One application of the new chip set that has excited HD Radio proponents is said to be its potential for cell phone handset applications. 'We believe the combination of the chip's low cost and high performance capabilities will enable us to make a profound impact on the marketplace for HD Radio products. Additionally, the low power and small footprint of our solution will help bring HD Radio technology to mobile phones and portable media players,' said Jungsuk Han, a Samsung spokesperson."

HD Radio is built on lies (and a two-hour battery life). I wonder if Struble ever figured out which engineer talked, and if that person still works at iBiquity?
 
One should make a distinction between movable electronics and portable electronics. I can make any HD radio movable - car battery and HD car radio, speakers, and antenna bolted onto a frame with wheels on the bottom. I can't make them portable.

An HD iPod? The power consumption of the HD chips would make the iPod too hot to put in a pocket. Especially a pants pocket. It would get hot in places you don't want to get hot!
 
Where do you mount the FM yagi and AM loop necessary to make HD radio reception work reliably at any reasonable distance with a HD radio equipped cell phone or pocket radio?

No doubt iBiquity is working on a way to make the 2 hour batteries used in HD radios proprietary (similar to inkjet cartridges) so they can monetize them with surcharges and licensing fees.

It appears that the engineering geniuses at iBiquity have already solved the portable HD radio antenna problem. Here's a link to a photo smuggled out of iBiquity headquarters in Columbia, Maryland. I believe it's Mr.Struble's children who are modeling the beta version of new antenna headwear.
