WR-G313i

In this internal HF model, the entire high-performance shortwave receiver is contained on a PCI card. This shields against the effects of a PC-generated interference. The demodulation is performed by an onboard DSP, allowing multiple receivers to be used 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. Numerous hardware options are factory-installed at the time of order-simple "Plug and Play" installation. 

Aside from audio recording and playback, the receiver can also record an entire 20 kHz wide IF spectrum. This allows you to analyze the received signal thoroughly and "re-receive" it with different IF filter bandwidths, notch filter, noise blanking, or demodulator settings to achieve 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 a susceptible receiver that can comfortably read CW signals under 0.05 µV input levels while also having a respectable 95 dB dynamic range that makes receiver resistant to strong signal overload. The receiver connects to an IBM-compatible PC via the USB port. A single PC can control several receivers to form a multi-channel HF receiver system. The receiver has an onboard DSP, and does not rely on the PC sound card for the signal input. However, the digitization is done in the receiver 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. The unit's features are similar to those of the WR-G313i internal unit.

WR-G305i

This is a third generation PC-Based Software Defined Receiver (SDR) for the VHF and UHF bands.

The receiver has a frequency range of 9kHz to 1,800 MHz and a sensitive front end with low phase noise. The upper limit can be expanded to 3,500 MHz with an optional downconverter. This receiver uses the computer’s audio board for the DSP processing to save money. 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 WR-G305i receiver, with identical performance. The PC demodulates 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 a variable IF bandwidth of 1 Hz to 15 kHz (in 1 Hz increments), a 20 kHz wide real-time spectrum analyzer with a 16 Hz resolution, a noise blanker and a notch filter. Additionally, an integrated recorder allows you to instantly record and playback the received signal. Similar to other G3 receivers, the WR-G315i can also record an entire 20 kHz wide IF spectrum. The difference with the WR-G305 series is that this model has its own onboard DSP and does not rely on the PC sound card for the signal input. The digitization is done in the receiver using a high-performance analog-to-digital converter. The receiver offers a variety of measurement facilities available, including received signal frequency accuracy, amplitude modulation depth, frequency deviation, THD (total harmonic distortion), and SINAD. An audio spectrum analyzer is also included, allowing real-time observation of the demodulated spectrum 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. A single PC can control several receivers to form a multi-channel HF receiver system.
