The WiNRADiO WR-G315e is a software-defined high-performance VHF/UHF
receiver (9 kHz to 1800 MHz, extendable to 8599 MHz using an optional Antenna Multiplexer and
Frequency Extender) with a USB interface, an external version
of the WR-G315i receiver.
This receiver is intended for government, military, security,
surveillance, broadcast monitoring, industrial and demanding consumer
The receiver offers an unparalleled flexibility given its SDR architecture, respectable dynamic range,
and high sensitivity. Many useful features complement the receiver, making it capable of filling
not only the role of a monitoring receiver but also that of a measuring receiver, such as the calibrated S-meter showing
the received signal levels in dBm, ĶV or S-units, down to the ‑140 dBm noise floor, several spectrum
analyzers, and many other features not usually found on receivers of this price.
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
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. (For example, an optional DRM decoder/demodulator is also available.)
Easily installed to any modern computer with the USB interface, this receiver represents an excellent mobile solution
for VHF/UHF listening and monitoring.
The WR-G315e software contains numerous advanced features such as three types of scanning, five types of squelch,
many tuning options, virtually unlimited memories and a rich on-line help facility:
There are numerous demodulation modes, 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
to instantly record and playback the received signal.
Apart from audio recording and playback, the receiver can also record an
entire 20 kHz wide IF spectrum, making it possible to thoroughly
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.
In addition to the real-time narrow-band spectrum analyzer, there is also a wide-band spectrum analyzer
which contains additional professional instrumentation facilities:
the ability to display minimum and maximum spectrum sweeps, search for
peaks, average spectra, save and print spectra, marker mode, etc.
Another useful feature, previously unavailable with receivers of this price class, is a test and measurement
measurements on the received signal including 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.
The unique research and education
function makes it possible to explore interactive block diagrams of the
software-defined demodulator, for
each demodulation mode, and observe demodulation taking place on
real-time signals using two spectrum analyzers and a vector voltmeter.
The Client/Server Option
makes it possible to control the receiver remotely via LAN or Internet.
The receiver may be located physically on the opposite side of the
globe, but to the user it will appear
as if it was connected locally.
