Thanks shadow,
Siri- did encounter buyers at 25 but with 2.7 million shares short I think most of the buying was short covering.
Also read this article it is very interesting..Basically lucent hasnt developed the chipset for sirus yet.. The chip is scheduled to be completed in January.. From what I've been reading/hearing is it is extremley difficult to get a singal in a moving vehicle. Although visteon is suppose to demostrate the not yet completed chip at a electronics show.
I'm expecting delays in the chip being completed or quality problems with the demonstratation..
Also taking the technical problems aside, I just dont see people paying $10 a month for pay radio... with cds and downloads from the internet becoming the strong hold..
Trading Monday should be interesting.. Nasdaq futures are up now 32.5. I'm still expecting a rally to 2800-3000 but I see it coming back and testing the lows.. Nasdaq needs to consoliate before it makes any sustainable rally.

At the same time, electronic component manufacturers such as Lucent Technologies and STMicroelectronics are developing chip sets for the receivers.
Engineers say that the technical challenges behind such systems are tremendous. "There are huge risks on this," said Ols of Delphi Delco. "You've got new technology from end to end. The satellites, broadcast studios, and chip sets are all new."
Prime among the technical challenges is the development of receivers and antennae that can receive and unscramble a signal while mounted aboard a moving target. "This is not like satellite television," said Tracy Stanyer, vice president of OEM alliances at Sirius. "People trying to reach a satellite television signal are stationary. Here, you're trying to get 2.3 Gigahertz into a moving vehicle and turn it into a usable signal."
Indeed, the complexity is such that engineers said that the chip sets haven't yet been fully completed. The Sirius chip set, however, is expected to be finished soon. Visteon Corp. (Dearborn, Mich.) Co. said it expects to run a demonstration of the Sirius system at the Consumer Electronics Show in early January.
The Sirius chip set incorporates eight chips, including an RF front end, a microcontroller (probably from NEC Corp.), several "DSP-like" ASICs for demodulation and decoding of the signal, and memory. A few components, including the RF front end, are said to be finished, while most of the ASICs still exist as emulations. All of the hardware for the Sirius system is expected to be completed within weeks, however.
For the Sirius system, all receiver manufacturers will use the same basic chip set, which is designed by Lucent Technologies Microelectronics Group (Allentown, Pa.). Each will, however, use the chip set to create its own "flavor" receiver. "The receiver makers will create different protocols to interface with the audio system used by the vehicle manufacturer," said Doug Wilsterman, vice president of receiver marketing and alliances for Sirius. "They'll also vary their packaging schemes and lay out the boards differently."
XM Radio, which plans to begin broadcasting in May or June, also is working on its own chip sets. Cooperative development on the XM chip sets is an ongoing effort involving STMicroelectronics, Fraunhofer Institute, Certicom, Digital Voice Systems and Lucent.
Receiver makers are currently working with engineers from both Sirius and XM Radio. "Our goal is to supply to all the major automotive OEMs," said Mark Horvath, marketing and brand manager for Visteon telematics and multimedia. "And the automakers choose their own broadcast partners, so we have to be 'delivery agnostic.' "Ongoing effort
Engineers from various companies are also working with automakers on new antenna technology. Antenna development is key, they say, if consumers want to get "CD-quality" sound.
"In a moving vehicle, you cannot reliably aim the antenna and keep it aimed there at all times," said Ols of Delphi Delco. "So the signal has to be configured in a significantly different manner and so do the antennas."
Vendors say they expect most vehicles to employ two antennae, possibly one in the rear window glass and one whip-type unit in front of the vehicle. That way, the receiver could "choose" the strongest signal and use the other antenna signal for error correction.
Engineers said that each antenna would incorporate two key elements: one aimed at the sky and another aimed at terrestrial repeaters.
For that reason, antenna design is expected to be closely allied to the choice of service provider. The reason: Sirius satellites will be located higher in space (about 60 degrees above the horizon) and require use of fewer repeaters, while XM satellites will be located at lower elevations. XM systems are expected to use about 1,500 ground-based repeaters, about 10 times as many as Sirius.
Some receiver makers plan to build their own antennae, while others are teaming with specialty vendors called for by automakers. Visteon, for example, said it will build its antennae in house. Delphi Delco, meanwhile, is working with its own Fuba Automotive Division (Rochester Hills, Mich.) and with such vendors as Receptec (Holly, Mich.), as well as others. |
