WR-G313 description :

The Winradio WR-G313 is an SDR receiver for HF and VHF, the basic version covers up to 30 MHz while the band from 30 to 180 MHz is optional requiring an additional module. The salient feature of this WiNRADiO device is the remarkable sensitivity that makes it possible to monitor for example CW signals on levels of just 0.05 uV, this performance is well suited to listening stations that use internal antennas or of limited size. The S-meter tool implemented in the interface also offers a high accuracy, the indication is available in addition to S standard points also in dBm and uV. The receiver has a circuit with mixed architecture. Analogous in the two frequency conversions, the first uses a 15 KHz wide quartz roofing filter composed of two 4-pole cells, subsequently digital integrating a dedicated DSP in the hardware to define the filtering of the signals and their demodulation. The computer, connected via USB to the WR-G313, implements further processing and analysis by means of the software.

The filters bandwidth is adjustable in 1 Hz steps over the entire 0.001 ~ 15 KHz range, thus covering all the listening needs in the various modulations. Spectrum analysis operates in real time on 20 KHz wide showing the signal components with a resolution of 16 Hz. The 20 KHz segment of the digitized IF can be recorded on the PC to be reproduced at another time by freely setting selectivity, mode, notch filter, noise-blank. As far as the analysis functions are concerned, the software allows to measure an entire set of parameters on the tuned channel such as the depth of modulation in the AM, the frequency deviation in the FM, the distortion and the SINAD that quantify the signal quality, the audio spectrum with a detail of 5 Hz. In addition to the narrowband spectrum analysis there is also the panoramic analysis function that incorporates very interesting display utilities such as the ability to show the traces of minimum / maximum activity and automatic search for the identification of emission peaks.

WR-G313 performance and practical notes :

Those interested in the receiver pay attention to the fact that the device is available in two versions. The most common Winradio WR-G313e (ndr: here described and visible in the image at the top of the page) is a module to be connected via USB to a PC, the Winradio WR-G313i instead develops into a PCI type card. The characteristics do not differ in practice while naturally the type of installation has radically different features. Requirements for the PC are a Pentium 500 MHz CPU or higher and Windows XP and following operating system. Aspect to highlight is that by virtue of its design the apparatus also works in conjunction with a computer dated or otherwise of modest performance. Further known on the spuries generated within the receiver by the various oscillators, these are small and not superior - as stated by the manufacturer - to equivalent signals of 0.4 uV in the antenna input. This behavior is appreciable in general terms but is flanked by a non-ideal image attenuation in the various contexts of use.
