WR G-305i

Convert your desktop PC into a most sophisticated radio monitoring station! The WiNRADiO WR-G305i is a software-defined PC-based wideband scanning receiver covering a frequency range from 9 kHz to 1800 MHz (optional down-converter to 3.5 GHz available).

The receiver comes on a standard two-third length PCI card and is compatible with all modern desktop computers with an available PCI 2.2 standard slot.

Features

 Frequency range from 9 kHz to 1800 MHz
     (except cellular bands where required by law)
 Software-defined demodulation

The WR-G305i is the first of our G3 Series of VHF/UHF software-defined receivers.

The "G3" stands for "the third generation": As the original, award-winning, first-generation WiNRADiO WR-1000i receiver was the world's first commercially available wide-band receiver on a PC card when launched over a decade ago, the newly introduced WR-G305i is the world's first commercially available software-defined VHF/UHF receiver on a PCI bus card.

A Software Defined Radio (SDR) is such where demodulation and last IF (intermediate frequency) processing are done entirely in software. Usually this means using a DSP, but in the case of the G305i, this processing is done on a personal computer using a sound card (most modern PCs are now faster and more powerful than many DSPs were only a few years ago). So, if you own a PC, the chances are that you already own an important part of a software defined radio receiver!

While the Standard Demodulator provides performance of a highly respectable scanning receiver including synchronous AM demodulation and a real-time spectrum scope, the optional Professional Demodulator offers even more: continuous IF filter bandwidth adjustment (in 1Hz increments), interactive block diagrams with two additional audio spectrum scopes, and even inbuilt THD and SINAD measurement facilities.

An optional DRM decoder/demodulator is also available.

The WiNRADiO G305i: A ground-breaking general-coverage receiver that opens many new possibilities in the world of both conventional and digital communications. Prepare to be amazed!
