FlexRadio Systems SDR-1000 User Manual

1 General Description
The SDR-1000 Software Defined Radio is an open-software; 1 or 100W
transceiver providing general coverage receive operation with amateur
radio band transmission between 12kHz and 60MHz.
The FlexRadio SDR-1000 is a complete Software Defined Radio (SDR) transceiver designed for Amateur
Radio use. It is the first fully open software transceiver that uses a personal computer (PC) for all Digital
Signal Processing (DSP) and control functions of the radio. General coverage receiver operation is provided
from 12kHz to 60MHz along with transmit capability on all licensed amateur bands within the coverage
range. The theory behind the SDR-1000 is described in detail in a four part QEX magazine series entitled,
“A Software Defined Radio for the Masses
1
.” The articles are available for download from the FlexRadio
website at www.flex-radio.com. There are also links on the site to other excellent reference materials related
to SDR and DSP theory.
Since its introduction, additional hardware components have been added to further improve the
functionality and performance of the SDR-1000. The PowerSDR
TM
software, written in C#.NET, provides a
full featured transceiver interface and digital signal processing for the SDR-1000. It is continuously
improved over time through open source enhancements supplied by both customers and FlexRadio
Systems.
The basic hardware consists of four boards in a stack within an enclosure. The hardware provides a LNA,
filters, mixer, power, i/o interfacing and 1W PEP driver. Also provided is a standard interface to the
optional Down East Microwave 2 meter low power transverter (intended for use in VHF, UHF, and
Microwave systems), as well as an interface to the optional 100W power amplifier and the ATU (LDG Z-
100). Additionally available is an optional interface for an external, customer supplied 10 MHz reference
clock oscillator that may provide precision frequency control.
The Contour ShuttlePro v2 USB controller offers the ability to control the radio the way you want to
without having to use a mouse or keyboard. With 15 programmable buttons and 2 concentric tuning dials
(one spring loaded jog dial), this accessory offers an unparalleled level of programmable hardware control.
