The WiNRADiO WR-G39DDCi 'EXCELSIOR' is a high-performance HF/VHF/UHF/SHF software-defined receiver with a frequency range from 9 kHz to 3500 MHz, with two independent channels of 4 MHz wide instantaneous bandwidth available for recording and further digital processing, plus a 16 MHz wide real-time spectrum analyzer. The receiver offers unparalleled flexibility given its SDR architecture, respectable dynamic range, high sensitivity, scanning speed, and accuracy of performance, making it capable of filling not only the role of a monitoring receiver but also that of a fast search receiver and measuring receiver, with many operational and instrumentation features not usually found on receivers of any price category. Frequency range 9 kHz to 3500 MHz (except cellular bands where required by law)

The receiver has a robust front-end, which features an up-converter for excellent suppression of mirror images, eliminating a need for complex pre-selector filters which introduce distortion and reduce the noise figure.

The receiver interfaces to a Windows-compatible PC via the PCI-e bus. Several receivers can reside on a single PC to form a multi-channel receiver system.

This is the first time a receiver of such advanced specification and unique combination of features is being offered to the general marketplace. The receiver is intended for government, military, security, surveillance, broadcast monitoring, industrial and demanding consumer applications. Easily installed on any modern computer with the PCI-e bus interface, this receiver represents an excellent general-purpose mobile and stationary solution for HF/VHF/UHF/SHF monitoring and surveillance. The WR-G39DDCi software contains numerous advanced features such as several types of searching and scanning, five types of squelch, many tuning options, virtually unlimited memories, and a rich online help facility.

There are two concurrent DDC channels with 24 selectable output bandwidths ranging from 20 kHz to 4 MHz. Each can be used as an independent "virtual receiver". There is also a simultaneous 16 MHz wide real-time spectrum analyzer.

There are numerous demodulation modes, continuously variable demodulator bandwidth from 1 Hz to 320 kHz (in 1 Hz increments), waterfall spectrum analyzers, scanning, searching, logging, and task scheduling facilities, as well as an audio real-time spectrum analyzer, test and measurement functions, noise blankers and notch filters.

There is also an integrated recorder, making it possible to instantly record and playback the received signal both at the IF and audio levels, for both channels. The recording offers also a pre-buffering feature in order not to lose any transmission.

The receiver is entirely software-defined, which means that additional demodulation or decoding modes can be easily added by a mere software change.

System requirements: PC with 2 GHz quad-core CPU or faster,

One PCI-e bus slot,

Windows XP, Vista, Windows 7 or 8.
