WiNRADiO Scandinavia G3 HF RECEIVERS G313 e/i G31DDC Excalibur G33DDC Excalibur Pro G35DDC Excalibur Ultra 9 kHz - 30 MHz (180 MHz) 9 kHz - 49,995 MHz 9 kHz - 49,995 MHz 1 kHz - 45 MHz Malmö - Sweden Phone 0705 164266 [email protected] www.winradio.se WR-G313e High Performance Software-Defined HF Receiver 9 kHz-30 MHz frequency range (optionally extendable to 180 MHz) Software-defined DSP demodulation Excellent sensitivity High dynamic range Continuously adjustable IF bandwidth Excellent suppression of internal spurii Real-time spectrum analyzer Graphical IF shift and notch filter Noise blanker Audio and IF recording and playback Test and measurement facilities 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. ® WiNRADiO 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. Specifications The receiver is supplied with an external AC/DC power adapter, working in linear mode to avoid even the slightest possibility of interference emanating from the power supply. Software The WR-G313e software contains numerous advanced features, many tuning and scanning options, virtually unlimited memories and a rich on-line help facility. Receiver type DSP-based SDR with DDS-based dual-conversion superheterodyne front end Frequency range 9 kHz - 30 MHz (optionally 9 kHz - 180 MHz) Tuning resolution 1 Hz Mode AM, AMS, LSB, USB, DSB, ISB, CW, FM Image Rejection 1.8-7.3 MHz: 80 dB 7.3-30 MHz: 70 dB Spurious-free dynamic range 95 dB IP3 +8.5 dBm @ 20 kHz Phase noise -148 dBc/Hz @ 100 kHz Internal spurious Internal spurious: Less than equivalent input of -105 dBm RSSI accuracy 2 dB RSSI sensitivity -137 dBm Bandwidth 1 - 15000 Hz (adjustable in 1 Hz steps) Scanning speed 400 steps/s (at 1kHz steps) Sensitivity Mode (AM/SSB/CW 10dB S/N) AM, AMS (FM 12dB SINAD) AM, AMS 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. 0.5-1.5 MHz 1.5-30 MHz -103dBm (1.6µV) -106dBm (1.1µV) -108dBm (0.9µV) (80% modulation) -111dBm (0.63µV) -115dBm (0.4µV) -116dBm (0.35µV) LSB, USB, ISB, DSB -115dBm (0.40µV) -118dBm (0.28µV) -119dBm (0.25µV) CW -122dBm (0.18µV) -125dBm (0.13µV) -130dBm (0.07µV) FM -110dBm (0.7µV) -113dBm (0.5µV) -117dBm (0.32µV) (30% modulation) 0.15-0.5 MHz Note: Below 150 kHz, the sensitivity gradually drops.

The signal test facility can perform various measurements on the received signal including frequency accuracy, amplitude modulation depth, frequency deviation, THD (total harmonic distortion) and SINAD. There is also a unique research and education function making 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. Specifications are subject to change without notice due to continuous product development. WR-G313i High Performance HF Receiver 9 kHz-30 MHz frequency range (optionally extendable to 180 MHz) Software-defined DSP demodulation Excellent sensitivity High dynamic range Continuously adjustable IF bandwidth Excellent suppression of internal spurii Real-time spetrum analyzer Graphical IF shift and notch filter Noise blanker Audio and IF recording and playback 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. ® WiNRADiO 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 15 kHz, two spectrum analyzers with 16 Hz resolution, graphically controlled IF shift and notch filter, and noise blanker.

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.

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 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.

There are several spectrum analyzer configurations available, including the 45 MHz full span with 1.5 kHz resolution. The scaleable spectrum display can be viewed in either the standard or waterfall mode. The digital down-converter provides 33 selectable output bandwidths ranging from 20 kHz to 32 MHz. The receiver's selectivity can be adjusted with 1 Hz resolution. Recording and playback are also provided at the output of the digital down-converter, whereby a 32 MHz wide spectrum chunk, representing the entire HF band, can be recorded for later demodulation and post-processing. DDC spectrum/waterfall, max 32 MHz wide, up to 1 Hz resolution bandwidth Channel spectrum, max 64 kHz wide, 1 Hz resolution bandwidth Demodulated audio, 24 kHz wide, 1 Hz resolution bandwidth ADC 16 bit, 100 MSPS AM -106 dBm (1.10 µV) @ 10 dB S+N/N, 30% modulation, 6 kHz BW Sensitivity SSB -121 dBm (0.20 µV) @ 10 dB S+S/N, 2.1 kHz BW (@ 10 MHz, preamp on, input filter bypass) CW -127 dBm (0.10 µV) @ 10 dB S+S/N, 500 Hz BW FM -117 dBm (0.31 µV) @ 12 dB SINAD, 3 kHz deviation, 12 kHz BW, Audio filter 300 – 3000 Hz, De-emphasis -6 dB/oct Tuning accuracy 0.5 ppm @ 25 °C Tuning stability 0.5 ppm (0 to 50 °C) The receiver is entirely software-defined, which means that additional demodulations or decoding modes can be easily added by a mere software change. Input filters In spite of the receiver's ground-breaking architecture, the user interface still remains simple and intuitive to use, with a rich on-line help facility. The control software contains 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.
