CommRadio is introducing the CR-1, a new tabletop shortwave receiver
US-based CommRadio is introducing a new tabletop, SDR-based, shortwave receiver this year: the CR-1. 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.
Other impressive features:
Can be powered from USB or a 6-18 VDC power source (from a separate 2.1mm jack). The CR-1 possibly has the most flexible power source I've ever seen in a shortwave receiver!
The knobs are black anodized machined aluminium and front panel is powder coated machined aluminium; case is 20 gauge powder coated steel
Three antenna inputs
BNC for HF/MW
3.5 mm audio jack (rated at 1000 Ohm, for roll-up antennas or telescoping whip),
