The WiNRADiO WR-G313e receiver is a USB-controlled,
software-defined high-performance HF receiver (9 kHz to
30 MHz, optionally extendable to 180 MHz).
Several WR-G313e receivers can be controlled by a single
PC, which provides an ideal solution for high-performance
multi-channel surveillance and monitoring systems.
This receiver is intended for government, military, security,
industrial, surveillance, broadcast monitoring, and
demanding consumer applications.
As the last IF and demodulation processing are entirely
software-defined, additional demodulation or decoding modes
can be easily added by a mere software change.
In addition to audio recording, the receiver can also record a
20 kHz wide spectrum at the IF level, making it possible to
thoroughly analyse a signal, and experiment with extracting a
weak signal with different filter settings for the best reception.
The receiver is lightweight and portable, an ideal accessory
for laptop and notebook computers. Every modern portable
computer can be quickly and easily converted into a powerful
HF monitoring station with minimum fuss.
The receiver is extremely sensitive, making it possible to
comfortably read CW signals well under -130 dBm input
levels, yet featuring a respectable 95 dB dynamic range
making the receiver resistant to strong signal overload.
The high sensitivity is also matched by that of the S-meter:
The calibrated S-meter shows the received signal levels in
dBm, µV or S-units, down to the receiver noise floor. The IF
bandwidth of the receiver is continuously adjustable from
1 Hz to 15 kHz, in 1 Hz steps.

Hardware
G313e Options
The construction of the WiNRADiO WR-G313e receiver is truly ground
breaking and innovative: The remarkably compact receiver connects
to the computer via standard USB interface which facilitates the
receiver control as well as transfer of the demodulated audio. The
enclosure is very well shielded against interference, making it
possible for the receiver to operate in a noisy computer environment.
The G313/180 Frequency Extension Option extends the frequency
coverage from the standard 9kHz-30MHz to 9kHz-180MHz. This makes
it possible to use this receiver for narrow-band communications in the
low VHF range. The receiver's variable IF bandwith makes this
receiver particularly suitable for surveillance and monitoring of civilian
and military aircraft and marine communications.
Other hardware options may be customized to specific customer
requirements, including external frequency reference, IF outputs, etc.
In addition to hardware options, there are many software options
available for this receiver, such as the DRM demodulation option,
Client/Server option, and others. Please visit our Web site
www.winradio.com for the latest news on the available options.

WiNRADiO G3 Series Demodulator
There are numerous modulation modes, variable IF bandwidth 1 Hz to
15 kHz, two spectrum analyzers with 16 Hz resolution, graphically
controlled IF shift and notch filter, and noise blanker. The built-in
recorder can record and play back demodulated audio as well as the
IF signal, which means that it is possible to "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 a weak or interference-prone signal.

Test and measurement facilities
The WiNRADiO WR-G313i receiver is a software-defined
high-performance HF receiver (9 kHz to 30 MHz, optionally
extendable to 180 MHz) on a PCI card. The front-end is a
DDS-based double-conversion superhet, the last IF stage is
implemented in software resident in the on-board DSP.
The high sensitivity is also matched by that of the S-meter:
The calibrated S-meter shows the received signal levels in
dBm, µV or S-units, down to the recever noise floor. The IF
bandwidth of the receiver is continuously adjustable from
1 Hz to 15 kHz, in 1 Hz steps.
This receiver is intended for government, military, security,
industrial, surveillance, broadcast monitoring, and
demanding consumer applications.
Several WR-G313i receivers can reside in a single PC (as
many as there are free PCI slots), which provides an ideal
solution for high-performance multi-channel surveillance
and monitoring systems.
As the last IF and demodulation processing are entirely
software-defined, this means that additional demodulation
or decoding modes can be easily added by a mere
software change.
Apart from the antenna and audio leads, there are no other
interface or power supplies cables - no clutter on your desk.
Every modern desktop computer can be converted into a
powerful HF monitoring station with minimum fuss.
The receiver is extremely sensitive, making it possible to
comfortably read CW signals well under -130 dBm input
levels, yet featuring a respectable 95 dB dynamic range
making the receiver resistant to strong signal overload.

COMMUNICATIONS
Hardware
The PCI card plugs into an available slot of an IBM-compatible PC.
There is a single SMA antenna connector and an output line audio jack
which can be used to connect the receiver output directly to a sound
card line-input or an amplified speaker.
Reference Oscillator Output Option (G313/RO)
The G313/RO option adds an external SMA connector to the receiver board,
which can be used to output the internal reference frequency. This is useful for
situations when the receiver's own internal oscillator is to be used as a reference
for other equipment, or, if an external reference is used, to provide this external
reference to other receivers in a daisy-chain arrangement. If the receiver relies
on its internal reference oscillator, this option will provide 16.384 MHz reference
output. If an external oscillator is used, then the external oscillator frequency will
be provided at this output.
Intermediate Frequency Output Option 45 MHz (G313/IF4)
The G313/IF4 option adds an external SMA connector to the receiver board,
which provides a wide-band IF output of the entire 9kHz-30MHz input band, upconverted to 45 MHz (i.e. 9 kHz corresponds to 45.009 MHz, 30 MHz corresponds
to 75 MHz). This makes it possible for the receiver to be used as a front-end
tuner for HF monitoring systems requiring the capability of digitizing the entire
HF band instantaneously; or a front-end for a spectrum analyzer, taking
advantage of the receiver's excellent sensitivity and low noise-floor level.
Intermediate Frequency Output Option 10.7 MHz (G313/IF1)
Similar to the previous option, the G313/IF1 option provides a wide-band IF
output.The difference is that this option involves an additional down-converter
which converts the 45 MHz IF down to 10.7 MHz.
To order a receiver with an
option from above, add the
option code(s) to the receiver
model number. For example,
for a 180MHz receiver with
external reference oscillator,
the model number will be
G313i/180/XR. Options can be
mixed together (except the IF
options where only one can be
selected, i.e. IF1 and IF4
cannot be selected at the same
time).
The receiver has its own on-board DSP, and does not rely on the PC
sound card for its performance. As the DSP performs the final stage IF
filtering and all demodulation, this receiver is entirely softwaredefined, which means that additional demodulation or decoding modes
can easily be added by a mere software change.
Software
The WR-G313i software contains numerous advanced features, many
tuning and scanning options, virtually unlimited memories and a rich
on-line help facility.
There are numerous modulation modes, variable IF bandwidth 1 Hz to

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 robust front-end is equipped with an ultrahigh-linearity amplifier which results in exceptional strongsignal performance. An advanced dithering technique
eliminates spurious signals without significantly increasing
the receiver's noise floor. The superior 16-bit 100 MSPS
analog-to-digital converter provides exceptional
performance over an extremely wide range of signals.
The entire 2 MHz DDC (digitally down-converted)
bandwidth is available for recording and demodulation.
Three demodulators allow the simultaneous reception of
three signal frequencies within the 2 MHz bandwidth.
The digital down-converter provides 21 selectable output
bandwidths ranging from 20 kHz to 2 MHz. Any bandwidth
can be fine-tuned 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'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, high sensitivity, 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 receiver is lightweight and portable, an ideal accessory
for laptop and notebook computers. Every modern portable

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 down-converted portion is highlighted and can be selected either via
keyboard or by the mouse cursor and then displayed in another window,
within which three independent receiver channels can exist. For any
channel, the receiver's selectivity, IF shift, passband tuning, notch, and
other functions can be adjusted, and the audio spectrum of the
demodulated signal can be observed.
The parameters of all three independent channels can be set separately,
allowing each to be recorded simultaneously and independently.
Recording and playback are also provided at the output of the digital
down-converter, where an entire 2 MHz spectrum band can be recorded
for later demodulation. Pre-buffering prevents signal loss at the start of a
transmission.
A flexible scheduler function allows unattended recording of each channel
at specified dates and times.
The software-defined architecture allows easy software upgrades for
demodulation and decoding requirements.
In spite of the receiver's ground-breaking architecture, the software still
remains simple and intuitive to use, containing all the features generally
expected in modern receivers such as noise blanking, memories,
scheduler, squelch (level, voice or noise activated), numerous tuning
options, and a wide choice of demodulation modes, including userdefined and optional DRM modes.

The receiver's robust front-end is equipped with an ultrahigh-linearity amplifier which results in exceptional
strong-signal performance. This already robust front-end
is further enhanced with a user-selectable preselector
that can operate either in a fully automatic or userconfigurable mode. As many as 119 different filter
combinations can be constructed by the user (91
bandpass, 14 low-pass and 14 high-pass). The front-end
employs 34 subminiature electromechanical relays (rather
than often used but distortion-prone semiconductor
switches) to ensure high dynamic range.
A user-selectable low-noise preamplifier provides
additional sensitivity for the receiver to be able to extract
even the weakest signals from noise.
The receiver's superior performance results from its
innovative, direct-sampling, digital down-conversion
architecture along with the use of leading-edge

channel, the receiver's selectivity, IF shift, passband tuning, notch, and
other functions can be adjusted, and the audio spectrum of the
demodulated signal can be observed.
The digital down-converter provides 24 selectable output bandwidths
ranging from 20 kHz to 4 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 parameters of all three independent channels can be set separately,
allowing each to be recorded simultaneously and independently.
Recording and playback are also provided at the output of the digital
down-converter, where an entire 4 MHz spectrum band can be recorded
for later demodulation. Pre-buffering prevents signal loss at the start of
a transmission.
In spite of the receiver's ground-breaking architecture, the software still
remains simple and intuitive to use, containing all the features generally
expected in modern receivers such as noise blanking, memories,
scheduler, squelch (level, voice or noise activated), numerous tuning
options, and a wide choice of demodulation modes, including user-defined
and optional DRM modes.

Test and measurement functions
The WiNRADiO WR-G35DDCi Excalibur Pro WB is a
high performance, direct-sampling, software-defined
wideband shortwave receiver with a frequency range
from 9 kHz to 45 MHz. It includes a real-time
45 MHz-wide spectrum analyzer and 32 MHz-wide
instantaneous bandwidth available for recording,
demodulation and further digital processing.
The entire 32 MHz DDC (digitally down-converted)
bandwidth is available for recording and demodulation.
Multiple demodulators allow the simultaneous reception
and decoding of radio signals within the entire HF band.
The receiver's robust front-end is equipped with an ultrahigh-linearity amplifier which results in exceptional
strong-signal performance while at the same time offering
excellent sensitivity.
The WR-G35DDCi Excalibur Pro WB also features
external reference clock inputs and outputs, as well as a
FPGA interface, allowing for phase-coherent system
configurations such as in high performance
interferometer direction finding applications.
This is the first time a receiver of such advanced
specification and unique combination of features is
being offered to the general marketplace.
The receiver's superior performance results from its
innovative, direct-sampling, digital down-conversion
architecture along with the use of leading-edge
components and design concepts. These all result in a
very high IP3, wide dynamic range, high sensitivity, and
accurate tuning. These key features create a receiver in
a class of its own, with wide application potential, with
many operational and instrumentation features not
usually found on receivers of any price category.
The receiver is intended for government, military,
security, surveillance, broadcast monitoring,
industrial and demanding consumer applications.
The WR-G35DDCi receiver represents an excellent
multi-purpose mobile and stationary solution for
advanced HF band monitoring and surveillance.
Hardware
The WiNRADiO G35DDCi Excalibur Pro WB receiver
breaks new ground with its state-of-the-art components,
such as a high-performance 16-bit 100 MSPS analog-todigital converter.
The receiver is very well shielded against interference,
making it possible to operate in a noisy computer
environment. The receiver card has very modest power
requirements of less than 10 watts, allowing it to be
powered from the PC’s internal power supply. There is
also provision for an external power supply feed in cases
where several of these receiver cards are to be installed
in a multi-channel configuration.
