The 'EXCALIBUR' is a high-performance, low-cost, direct-sampling, software-defined, 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 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, excellent sensitivity, selectivity 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 WR-G31DDC software provides an elegant and logical graphical user interface. 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 digital down-converter provides 21 selectable output bandwidths ranging from 20 kHz to 2 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 'EXCALIBUR Pro' is a high-performance, low-cost, direct-sampling, software-defined, shortwave receiver with a frequency range from 9 kHz to 49.995 MHz. It includes a real-time 50 MHz-wide spectrum analyzer and 4 MHz-wide instantaneous bandwidth available for recording, demodulation and further digital processing. This product is an advanced version of the WR-G31DDC receiver, offering many additional features and improvements, such as for example: 4 MHz instantaneous processing bandwidthLow-noise preamplifierConfigurable preselection filtersFilter bandwidth adjustable down to 1 Hz0.5 ppm frequency stabilityTest and measurement functionsPause functionThe 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.

The WiNRADiO WR-G35DDCi Excalibur Ultra is a high performance, direct-sampling, software-defined ultra-wideband shortwave receiver with a frequency range from 1 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 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 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.
