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 SpectraVue™ 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.

SDR-IQ January 20, 2012
Reviewer: Carmelo Falzon from Cranbourne, Victoria Australia  
Had this receiver for a few days my main intrest is to monitor hf aero installation was easy only took a few minutes hooked up my Wellbrook-ALA1530 and the performance was excellent i do not have any noise issues and have also tried it portable hooked up a piece of wire 20 metres long and ran it on my Miracle Ducker-IL antenna tuner results where excellent if u havent got a decent antenna on hf u are not going to get any where regardless what radios u have i do have other receivers from Aor,Drake,Icom,
Palstar,Racal,Ten Tec but the SDR-IQ is definetley a keeper very happy with the Purchase..

Regards Lino..

Many features, mediocre performance January 31, 2010
Reviewer: Paul Huffman from Springfield, OH United States  
The reason I purchased this model is that it is powered by the USB cable - no messy wall ward hanging off the back. The screen window does has many features including a variety of spectral displays; demodulators for AM, FM, SSB and CW; and infinitely variable filter widths.  Other reviews have focused on its use as a panoramic adaptor.  My review will summarize its performance as a SW receiver.  First, an outside antenna is a must to get away from PC noise.  Even then, my portable with a telescopic antenna was able to pull signals out of the noise that were completely absent from the SDR-IQ.  Also, the audio output to the sound card is weak.  I have to set both the main and WAV volume controls to max for a reasonable listening level.  The bottom line:  It is great for spectral analysis or for use as a panoramic adaptor.  If you just want to listen to shortwave, get one of the many available portables or, better yet, buy a desk top communications receiver.
