The SDR-IQ is a 14-bit software defined radio receiver. It offers a broad range of spectrum analyzer and demodulation capabilities. The hardware samples the whole 0.0001-30 MHz band using a high performance, 14 bit analog to digital converter (ADC) running at 66.6 MHz. The digital data from the ADC is processed into I and Q format using a direct digital converter (DDC). The I and Q data is then sent to the PC for processing using a USB 2.0 interface. All of the demodulation and spectral functions are done on the PC side.

The SDR-IQ™ comes with a High Frequency (HF) amplified front-end with switched attenuators, switched filters and 1Hz tuning. The SDR-IQ™ comes with the latest version of Moetronix SpectraVue™ and SDR-Radio software. It supports AM, WFM, USB, LSB, N-FM, DSB and CW with fully adjustable DSP Filter bandwidths and FFT sizes of 2048 to 262144 points. The resolution bandwidth is as low as 0.031 Hz.

Uses:-
High performance HF Receiver with 190 KHz realtime Panoramic Adapter
Ultrasound experimentation (Sonar, Underwater ultrasound, Bat and Insect detectors)
IR (Infrared) subcarrier detection and communications
Record up to 190 KHz of spectrum to hardrive for later playback and demodulation
Panoramic adapter for Communication Receivers (any IF in HF band 455 KHz, 8.83 MHz, 10.7 MHz, 21.4 MHz, etc)
Very Low Frequency (VLF) Studies
Spectrum Analyzer backends
Processor for Radio Astronomy receivers

Features:-
Smallest SDR with RF DSP™ that samples the whole HF band at once and performs the initial filtering at 67 MHz sample rate with 23 bit accuracy. Uses a high performance Analog Devices 14 bit analog to digital converter.
Sends 16 bits of I/Q Data to the PC via USB. No messy soundcard cables required.
SDR-IQ is USB powered. No power supply is required. Works great with laptops running on batteries.
Incredible receive performance.
High resolution spectrum display with higher resolution and speed than those in $10K radios.
RF preselection filters for great IMD performance.
Serial port to directly interface with radios like the Icom IC-R8500, IC-R9000, IC-R9500, IC R7000, IC-R7100 and AOR AR-5000.
50 ohm RF input that can be easily interfaced to antennas, Ultrasonic transducers, IR detectors, and other RF equipment.
Open source ActiveX control and ActiveX sample program for easy software customization. SpectraVue (not open source).
Windows, Linux and Mac OS drivers for developers.
Network server that allows remoting of the SDR-IQ™. Servers available for both Windows and Linux.
Adds the best panoramic display features to transceivers like the Yaesu FT1000MP MV, FT2000, FT9000 , FTDX5000 and IC-7800 using the RX output connector, RX loopback or IF Output.
