WR-G31DDC HF SDR Receiver

WR-G31DDC HF SDR ReceiverThe 'EXCALIBUR' is a high-performance, low-cost, direct-sampling, software-defined, shortwave receiver with a frequency range from 9 kHz to 50 MHz. It includes a real-time 50 MHz-wide spectrum analyzer and 2 MHz-wide instantaneous bandwidth available for recording, demodulation and further digital processing. 

The receiver's superior performance results from its innovative, direct-sampling, digital down-converter architecture along with the use of leading-edge components and design concepts. These all result in a very high IP3, wide dynamic range, excellent sensitivity, selectivity and tuning accuracy. These key features create a receiver in a class of its own, with wide application potential, at a very affordable price.

The WR-G31DDC software provides an elegant and logical graphical user interface. There are several spectrum analyzer configurations including the 50 MHz full span with 1.5 kHz resolution. The fully-zoomable display can be viewed in either the standard or waterfall mode. The digital down-converter provides 21 selectable output bandwidths ranging from 20 kHz to 2 MHz. The receiver's selectivity can be adjusted with 1 Hz resolution. The bandpass audio filter's low and high cut-off frequencies are graphically adjustable, as is the notch filter and noise blanker.

The receiver interfaces to a Windows-compatible PC via the PCI-e bus. Several receivers can reside on a single PC to form a multi-channel receiver system.

WinRadioWR-G313i

This is an internal HF model, where the entire high-performance shortwave receiver is contained on a PCI card, extremely well shielded against the effects of PC-generated interference. The demodulation is performed by an on-board DSP, which makes it possible to use multiple receivers in a single computer. Numerous functions and facilities include recording and playback (both audio and IF spectrum), IF shift, continuously variable IF bandwidth 1 Hz to 15 kHz (in 1 Hz increments), notch filter, noise blanker, and several test and measurements facilities including several spectrum analyzers. There are also numerous hardware options, factory-installed at the time of order. Simple "Plug and Play" installation. 

Apart from audio recording and playback, the receiver can also record an entire 20 kHz wide IF spectrum, making it possible to thoroughly analyze the received signal, and "re-receive" the same signal again and again with different IF filter bandwidths, notch filter, noise blanking or demodulator settings, to arrive at the best possible reception of weak or interference-prone transmissions.

WR-G313e

This is the external version of the WR-G313i HF model. It is an extremely sensitive receiver, making it possible to comfortably read CW signals under 0.05 µV input levels, yet featuring a respectable 95 dB dynamic range making the receiver resistant to strong signal overload. The receiver connects to an IBM-compatible PC via the USB port. Several receivers can be controlled by a single PC to form a multi-channel HF receiver system. The receiver has its own on-board DSP, and does not rely on the PC sound card for the signal input; the digitization is done in the receiver itself, using a high-performance analog-to-digital converter. As the DSP performs the final stage IF filtering and all demodulation, this receiver is entirely software-defined, which means that additional demodulation or decoding modes can be easily added by a mere software change. All the features of this unit are similar to those of the WR-G313i internal unit.

PC-Based Dedicated VHF/UHF Receivers

PC-Based Dedicated HF Surveillance ReceiversWR-G305i

This is a third generation PC-Based Software Defined Receiver (SDR) for the VHF and UHF bands. With a frequency range of 9 kHz to 1,800 MHz the receiver features an extraordinarily sensitive front end and very low phase noise. The upper limit can be expanded to 3,500 MHz with an optional downconverter. To keep costs down this receiver uses the computer’s audio board to the DSP processing. Operating modes are AM, AMN, AMS, LSB, USB, CW, FM3, FM6, or FMN modes. The basic WR-G305i comes with a Standard Demodulator.

WR-G305e

The WR-G305e is an external (USB interface) version of the above WR-G305i receiver, with identical performance. The demodulation is performed by the PC using advanced digital signal processing techniques. Simple "Plug and Play" installation.

WR-G315i

The WR-G315i is a software-defined high-performance VHF/UHF receiver (9 kHz to 1800 MHz, extendable to 3500 MHz using an optional Antenna Multiplexer and Frequency Extender) on a PCI card. This receiver has continuously variable IF bandwidth 1 Hz to 15 kHz (in 1 Hz increments), a 20 kHz wide real-time spectrum analyzer with 16 Hz resolution, noise blanker and notch filter. There is also an integrated recorder, making it possible to instantly record and playback the received signal. Like other G3 receivers, the WR-G315i can also record an entire 20 kHz wide IF spectrum. A difference with the WR-G305 series is that this model has its own on-board DSP, and does not rely on the PC sound card for the signal input; the digitization is done in the receiver itself, using a high-performance analog-to-digital converter.

The receiver has various types of measurement facilities available such as received signal frequency accuracy, amplitude modulation depth, frequency deviation, THD (total harmonic distortion) and SINAD. An audio spectrum analyzer is also included, making it possible to observe the demodulated spectrum in real-time with a resolution of 5 Hz.

WR-G315e

This is the external version of the WR-G315i with very similar features. The receiver connects to an IBM-compatible PC via the USB port. Several receivers can be controlled by a single PC to form a multi-channel HF receiver system.
