WiNRADiO Future of radio


Note: This model has been superseded.
Please consider our suggested replacement model.


The WiNRADiO WR-G303e is a software-defined PC-based HF receiver (9 kHz to 30 MHz). It represents an external version of the award-winning WR-G303i receiver, with equivalent performance.

The PC-based receiver is USB-controlled and compatible with modern desktop and laptop computers with USB interface. An optional serial interface is also available.

The WiNRADiO G303e: A ground-breaking shortwave receiver that will surely amaze you.

G3 - the third generation The WR-G303e is another member of our award-winning family of G3 software defined receivers.

A Software Defined Radio (SDR) is such where demodulation and the last IF (intermediate frequency) processing are done entirely in software. Usually this means using a DSP, but in the case of the G303e, this processing is done on a PC. 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 conventional receivers, the WiNRADiO G303e receiver excells particularly by the ability of its demodulators: While the Standard Demodulator provides performance of a highly respectable shortwave 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 built-in signal measurement facilities.

An optional DRM decoder/demodulator is also available.
