The RadioComm CR-1
US-based CommRadio is introducing a new tabletop radio this year: the CR-1, an SDR-based shortwave/VHF/UHF receiver Their website has a few specifications and the video I’ve embedded below.
The CR-1 receives the full medium wave and shortwave spectrum (.5-30 MHz), plus some portions of VHF and UHF (FM broadcast band, Aircraft, Marine, NOAA weather radio, GMRS and FRS services).
The receiver architecture is a dual conversion super-heterodyne design with low-IF , I-Q digital sampling, 16 bit DSP with digital audio CODEC. Their website also mentions DSP algorithms for all demodulation: DSB-AM, SSB, CW, WBFM, NBFM and channel filtering.
