This new low-cost receiver (intended for experimenting and hobby use) continues in the fine tradition established by WiNRADiO's successful range of wide-band PC-based receivers.
The "G3" stands for "the third generation": As the original, award-winning, first-generation WR-1000i receiver was the world's first commercially available wide-band receiver on a PC card when launched years ago, the newly introduced WR-G303i is the world's first dedicated shortwave receiver on a PC card. It is also the first commercially available receiver where the entire final intermediate frequency stage and an all-mode demodulator are entirely executed in software, running on a personal computer.
The WiNRADiO G303i: A ground-breaking shortwave receiver that will surely amaze you.
A Software Defined Receiver (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 G303i, 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 Receiver!
Combining modular hardware design with innovative software, the G303i receiver exhibits flexibility not normally found on other PC-based receivers, let alone conventional receivers.
In addition to the flexible and friendly user interface of a PC-based receiver, with its numerous functions and facilities not normally available on any conventional receiver, the WiNRADiO G303i Software-Defined Receiver excels 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 inbuilt THD and SINAD measurement facilities.
Additional demodulator types are planned as further options, including a DRM (Digital Radio Mondiale) demodulator.
