The next toy I am really eyeing for the shack is the Excalibur from Winradio. 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. This true SDR receiver includes a real-time 50 MHz-wide spectrum analyzer and 2 MHz-wide instantaneous bandwidth available for recording, demodulation and further digital processing.
