WiNRADiO WR-G35DDCi HF Receiver

The WR-G35DDCi control software provides a highly functional and logical user interface. There are several spectrum analyzer configurations available, including the 45 MHz full span with 1.5 kHz resolution. The scaleable spectrum display can be viewed in either the standard or waterfall mode.

The digital down-converter provides 33 selectable output bandwidths ranging from 20 kHz to 32 MHz. The receiver's selectivity can be adjusted with 1 Hz resolution.

Recording and playback are also provided at the output of the digital down-converter, whereby a 32 MHz wide spectrum chunk, representing the entire HF band, can be recorded for later demodulation and post-processing.

In spite of the receiver's ground-breaking architecture and powerful functionality, the user interface still remains simple and intuitive to use, with a rich on-line help facility. The control software contains all the features generally expected in modern receivers such as noise blanking, memories, scheduler, squelch (level, voice or noise activated), numerous tuning options, and a wide choice of demodulation modes, including user-defined and optional DRM modes. The parameters of all three independent demodulator channels can be set separately, allowing each to be recorded simultaneously and independently. Recording and playback are also provided at the output of the digital down-converter, where an entire 32 MHz spectrum band can be recorded for later demodulation. Pre-buffering prevents signal loss at the start of a transmission. A flexible scheduler function allows unattended recording of each channel at specified dates and times.

There is also a unique "pause" function, the world's first for a shortwave receiver, making it possible to pause reception and resume it when convenient. This is very useful in case the receiver is left unattended for a period of time.

A "toolbox" full of various test and measurement tools, such as frequency error, SINAD, THD and modulation meters, logger and scheduler, complement the entire package and make it possible to use this product as a measuring receiver, replacing much more expensive (and often less capable or accurate) conventional test equipment.
