The WiNRADiO WR-G31DDC „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.
