"COMMUNICATIONS QUARTERLY" Reports a Milestone in Communications
Receiver Development!
 
The upcoming Spring 1995 issue of "COMMUNICATIONS QUARTERLY" will
feature an article titled: "The Watkins-Johnson HF-1000A Milestone in
Communica- tions Receiver Development." This informative piece is
written by Scott D. Prather, KB9Y, an author who is frequently
published in the Quarterly.
 
Those of you who would like to learn about this new receiver will find
a plethora of information that will explain in detail what it is and
how it works. Mr. Prather begins his article: "The Watkins-Johnson
HF-1000 is the first affordable, stand-alone commercial receiver to
use digital signal processing (DSP) at the IF level. In the HF-1000,
DSP provides IF selectivity, demodula- tion, noise blanking, fine
tuning, passband tuning, and signal strength calculation, along with
several other features ... The use of DSP in the HF-1000 represents a
major turning point in receiver technology." One key piece of
information offered by Mr. Prather is that the unit is relatively
simple to use. He explains: "I found I could execute about 90 percent
of the receiver's features without referencing the manual." In
conclusion, the author continues: "So, what's it like to use a digital
receiver? It's unbelievable!  ... the HF-1000 [is] the most enjoyable
receiver I've ever operated." "Watkins-Johnson has made a brilliant
move into the future of communications receivers."
 
The article features such topics as: an overview of the HF-1000, the
HF-1000 RF assembly, a brief tutorial on Digital Signal Processing,
the HF-1000 digital control assembly, and using the HF-1000.  Other
features include a schematic of the Siliconix Si8901 high-intercept
mixer and photographs of the RF and digital assemblies within the
HF-1000.
