product description
WR-G305e Wide-Band Receiver with Standard Demodulator
>>> Prices and availability on request!
The WiNRADiO WR-G305e is a software-defined PC-based wideband receiver (9 kHz to 1800 MHz, expandable to 3500 MHz with an optional downconverter). It represents an external version of the WR-G305i 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 WR-G305e is another member of the G3 software defined receiver family. 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 G305e, 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!

Options
The following factory-fitted hardware options are available for WR-G305e receiver:
- Wide-FM option (/WMF): With the standard G305 receiver, the FMW mode button is disabled and the wide FM demodulation mode is not available. This is because wide FM demodulation is not possible to be provided as part of the G305 software-defined radio system, within the constraints imposed by the processing power of a standard personal computer. However, wide-bware-defined" receiver which shares only the main receiver's front-end and first mixer, but has an independand FM demodulation capability is available as a factory-installed option. This is in fact a self-contained "hardent wide-band analog processing circuit with a conventional "hardwired" demodulator. If the Wide FM Option is installed, the FMW button becomes active. The demodulator spectrum display shows real-time spectrum of the demodulated audio. In the Professional Demodulator there is a user-definable audio filter, displayed superimposed over the audio spectrum and graphically adjustable (Item No. 9195).
- Professional Demodulator Option (/PD): The Professional Demodulator offers additional demodulation modes and fully user-adjustable demodulation parameters, complete with interactive block diagrams of the internal structure of the demodulator, an additional dual real-time spectrum scope with vector voltmeter, SINAD and THD measurement, and many other facilities. It adds DSB and ISB modes, additional Audio AGC settings and continuous IF bandwidth adjustment (from 100 Hz to 15 kHz). There are also user-definable IF bandwidth preset buttons at the bottom. Many more exciting facilities are hidden under the Setup button - optimized filter settings make it possible to increase the receiver sensitivity typically by 2 dB on AM, SSB and FM and by up to 10 dB on CW (Item No. 9196).
- Wide-FM and Professional Demodulator Option (WFM/PD): WR-G305e receiver with both above mentioned options (Item No. 9197).
