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
