What we need is an objective opinion on the significance of the Direct Conversion RF chip. I am not an engineer and do not completley grasp the significance of this discovery. Once WE understand its significance the company will have to educate the rest of the public.

I am going to call PRKR's PR firm and get them to pull together some independent articles and opinions about direct conversion RF receivers and get PRKR to post them at their website. This will serve the purpose of educating us and the general public.

Summary of July 9th PR and Call

Here is the conference call replay number (800)633-8284 x4478294.

Here is a laymen's summary of the call. I guarantee that some of the details are wrong, but the gist of the story is correct:

Background -

** History of Current Heterodyne RF De facto standard **
Heterodyne architecture was developed in the 1930's to enable the transmittal of data (at the time voice) using radio frequencies. It was designed before the transistor for analog applications. Voice data is loaded onto radio frequencies using amplitude modulation (AM) @ 540 to 1300 megahertz (MHZ) frequencies or frequency modulation (FM) @ another range. Just look at your radio dial. The heterodyne receiver intercepts the high frequency signal and reduces (demodulates) the signal to a lower frequency that our ears can hear in several steps. Each demodulation step reduces the integrity of the data (sound) transmitted. A similar approach is used for television sound, global positioning systems (GPS), cellular phones, and wireless local area networks (WLANS). The heterodyne architecture must be redesigned for each major new application in a different part of the RF spectrum.

** Parkervision's breakthrough: **
Parkervision has developed a universal wireless radio frequency (RF) receiver ("DIRECT2DATA") with the following attributes:
 Specifically designed for digital applications
 Complete system has been put on a chip (integrated circuit)
 Receiver allows direct conversion of radio frequencies - no demodulation required means no intermediate frequencies, better data integrity and a RF part reduction of 75% to 90%
 Less power than existing RFs - will cut power required in cell phones by 3 to 4 times, greatly extending battery life (chip operates at 3.5 volts with under 10 milliamps current)
 Input frequency of 2 MHZ to 3 GHZ - includes radio, TV, cell phone, GPS and WLANS
 One chip maintains performance across the whole spectrum - no multiple architectures required
 Technology is in it's infancy and is capable off multiple iterations to improve performance from the already impressive stage it is in now
 Currently have 12 U.S. and 5 foreign patents

This is such a huge breakthrough from an unlikely source that many are skeptical. The breakup with IBM scares them. The certification by Boeing gives me comfort. When PRKR comes out with the specs of the first product to include their chip (hopefully this quarter) and the first product is actually produced (hopefully early 1999), delivered and tested, this stock will skyrocket (if it works). We are talking about a quantum leap in technology used in everyday items.

This stock is either the next Intel or the next ZZZBest.

Other events:

7/23/97 - PARKERVISION AND IBM JOIN FORCES TO CREATE WIRELESS COMPUTER PERIPHERALS

1/27/98 - Parkervision and IBM terminate relationship after failing to agree on chip testing procedure.

3/3/98 - Boeing Microelectronics validates performance of direct conversion chip. Boeing validates that theories, discrete prototypes and chips all perform the same. Boeing allows PRKR to distribute report on Boeing letterhead.

7/9/98 -- PARKERVISION " DIRECT2DATA" INTRODUCED IN RESPONSE TO MARKET DEMAND -Company Targets Technology To Become New Standard Replacing Rf Heterodyne Architecture

Electronic Design (March 23, 1998)

From the engineers @ Electronic Design (March 23, 1998) comes this on the chip that Boeing tested. PRKR has advanced past this stage to the "Direct2Data" digital technology capability, but this article provides some credibility to PRKR's claims.

Novel Direct Conversion Receiver Reduces Component Count
By demonstrating specifications with a sensitivity of -104 dB, a 1-GHz bandwidth, an IP3 of +15 dB, and a 5-dB noise figure, a new direct-conversion-receiver architecture is setting its sights on becoming a key building block for wireless systems. While the details are still sketchy, pending patent filings, the new design promises to reduce both component count and power requirements in applications such as audio, video, and data links; cellular phones; pagers; cordless phones; and cordless computer peripherals.

Prototype versions of the receiver have been fabricated in both CMOS and GaAs. Early tests show that it can substantially reduce parts count in most applications. The circuit's developers, ParkerVision Inc., claim that it only takes five components, worth about $5, to implement a 900-MHz radio. Using a conventional approach with that same radio, parts count soars to around 30, and it would have a BOM of $12.

At a recent demonstration, a prototype receiver IC was shown to receive a wideband signal centered around 980 MHz with almost no discernable amplitude or phase distortion while drawing less than 10 mA of 3.5-V power. Requiring no narrowband LNA front end, the receiver can convert two or more signals down to its baseband simultaneously. If this seems like science fiction, parties interested in licensing the technology or purchasing components will soon be able to obtain test results from an independent lab.

Obviously a few people are buying. In the absenceof more information, I think most are waiting for a licensing agreement before jumping in.

Is the thread dead or what? At least the stock is doing well.

I Agree. The problem with this stock is the lack of public information. Somebody obviously believes that PRKR's new technology works since they have driven the price from $13 to $30.

Asensio & Company: ParkerVision Possesses No Valuable Technology

NEW YORK, Sept. 28 /PRNewswire/ -- The following is being issued by Asensio & Company, a member of the National Association of Securities Dealers, CRD number 31742:

Investors may be buying shares of ParkerVision, Inc. (Nasdaq: PRKR) believing the company's claims that it invented a unique direct conversion radio frequency ("RF") integrated circuit ("IC"), and then created a new and universal "standard" for the front-end of transceivers it calls Direct2Data ("D2D"). These claims are completely false. Direct conversion is not new, unique or a standard suitable for all applications. On the contrary, direct conversion has been commonly used in consumer microelectronics since the early 1980s and is constantly being upgraded by its many existing suppliers. Furthermore, ParkerVision is neither an IC nor a RF supplier of any kind of application-specific or universal RF IC. In fact, ParkerVision has no legitimate industry presence and has never provided any verifiable evidence that D2D even exists, much less that it works as claimed. However, as part of our analysis, we assumed that the D2D performs as claimed and can be economically manufactured. Even using these baseless assumptions, we found that ParkerVision's D2D claimed attributes are all either commonly available, or if desired, can be readily created by existing suppliers. ParkerVision announced this "technology" years ago, but has resoundingly failed to generate a single sale or licensing agreement. Yet ParkerVision and its stock promoters have managed to increase its fully diluted market value from approximately $32.7 million to its current $403.9 million valuation, based almost exclusively on its wireless technology claims. ParkerVision possesses no asset or business with the remote potential to support its current stock price. Therefore we believe both that ParkerVision has purposefully disseminated false product claims in order to defraud investors, and that its shares are grossly overvalued. As a result, we believe ParkerVision's shares will soon trade well below $5 per share.

ParkerVision began promoting its alleged "major breakthrough in wireless technology" over 3 1/2 years ago. During the last two years, ParkerVision has been making ever more elaborate claims. It has used its wireless promotion to almost double its public float from 3.7 million shares to over 7.1 million shares without ever selling any of these additional shares through a legitimate public underwriting. ParkerVision's "pump and dump" stock operation has used a combination of false product claims, private offshore stock sales and the granting of options at no cost, to allow the sale of over 3.4 million shares of its grossly overvalued stock to the public. ParkerVision first sold all of these shares to its insiders, who were then able to "dump" their shares on the public. These insider sales occur without the public knowing they are buying "dumped" stock. During this period ParkerVision's stock promotion switched from its failed plans to develop a consumer version of the CameraMan system to the failed StudioMan product to conducting research in "wireless technologies." We believe ParkerVision needed to create its wireless stock promotion to hide its failure to deliver on earlier claims, its dismal financial performance, and to support a baseless 600% increase in its stock price that occurred simultaneously with a 90% increase in its public float.

Asensio & Company, Inc. is a New York-based institutional investment bank specializing in corporate valuations and equity research. Asensio & Company also specializes in investigating fraudulent stock promotions and publishing research on companies it identifies as grossly overvalued, as defined. A complete documented history of Asensio's published work with fraudulent securities transactions, and the firm's definition of gross overvaluation, is available on the Internet at www.asensio.com . Asensio & Company is actively engaged in short selling, including companies that are the subject of the firm's research reports, and advises its clients on securities it believes are overvalued.
