Introducing a breakthrough

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 (expandable to 3500 MHz with an optional downconverter).

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.

G303i - a PCI card shortwave receiver


 Frequency range from 9 kHz to 1800 MHz
     (except cellular bands where required by law)
 Software-defined demodulation
 Extraordinary sensitivity
 Tracking front-end filters
 Excellent strong signal handling
 Real-time spectrum analyzer
 Spot-on tuning in 1Hz steps
 Accurate signal strength indicator
 Fast scanning speed
 Multiple squelch modes
 Very low phase noise
 DRM decoder option
 APCO P25 decoder option
 3.5 GHz downconverter option
 Standard PCI interface
 Plug and Play installation

With the Professional Demodulator Option, the many additional features include:

 Continuously variable IF bandwidth 100 Hz - 15 kHz
 User adjustable filter selectivity
 WiNRADiO Digital Bridge™ compatibility
 Built-in test and measurement instrumentation
 Interactive block diagrams

Marine Application Suite (software option):

The Marine Application Suite adds dedicated marine features, further enhancing the capabilities of the G305 receiver. This includes decoding of HF Fax, NAVTEX, HF/VHF DSC and TELEX.

G3 - the third generation 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!

In addition to the flexible and friendly user interface, with its numerous functions and facilities not normally available on any conventional receiver, the WiNRADiO G305i receiver excells particularly by the ability of its demodulators.

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!
