<p class=MsoNormal><font size=3 face="Times New Roman"><span style='font-size:
12.0pt'>Ever since Gerald Youngblood K7SDR published a series of articles in
QEX magazine and offered the first, off the shelf SDR transceiver, Ham’s
worldwide have been forging ahead into the “Future of Radio”.
Although not the only exploration into SDR, at the time, the SDR-1000 and GPL
PowerSDR open source code has been a major engine to spur new exploration. Indeed
a very common remark on the various forums is “SDR has brought the
enjoyment back into ham radio for me!” Once again hams are at the very
leading edge of radio both in concept as well as SDR enabled operational modes.
Not all major SDR efforts can be covered in such a short forum, however, here
is a sampling of many fantastic experiments and full blown projects going on
from hardware to software to future possibilities.<o:p></o:p></span></font></p>

<p class=MsoNormal><font size=3 face="Times New Roman"><span style='font-size:
12.0pt'>The HPSDR is an open source (GNU type) hardware and software project
intended as a "next generation" Software Defined Radio (SDR) for use
by Radio Amateurs ("hams") and Short Wave Listeners (SWLs). It is
being designed and developed by a group of SDR enthusiasts with representation
from interested experimenters worldwide.<o:p></o:p></span></font></p>
<p class=MsoNormal><font size=3 face="Times New Roman"><span style='font-size:
12.0pt'><o:p> </o:p></span></font></p>
<p class=MsoNormal><font size=3 face="Times New Roman"><span style='font-size:
12.0pt'>The design is modular, so an experimenter can choose the bits and pieces
required to implement his own creation. This is similar to creating
something from Lego blocks.<o:p></o:p></span></font></p>

<p class=MsoNormal><font size=3 face="Times New Roman"><span style='font-size:
12.0pt'>The initial system consists of a motherboard/chassis to contain and
power the modules, along with a few building blocks for SDR.<o:p></o:p></span></font></p>
<p class=MsoNormal><font size=3 face="Times New Roman"><span style='font-size:

<p class=MsoNormal><font size=3 face="Times New Roman"><span style='font-size:
12.0pt'>The resulting device might be used as an IF interface between a radio
and the USB port a PC, much like a soundcard. Or it might be a high-speed
digitizing system to implement an HF spectrum analyzer. Or it could be a
self-contained, portable radio transceiver.<o:p></o:p></span></font></p>

<p class=MsoNormal><font size=3 face="Times New Roman"><span style='font-size:
12.0pt'>Key to the design of the first few modules is the use of Field
Programmable Gate Arrays, or FPGAs. These are chips whose characteristics
you can define! Draw a schematic and the chip implements it. Or
describe the function in words, and the chip performs it.<o:p></o:p></span></font></p>
