Detailed Product Description
Introducing the New CR-1 Communications Receiver. (Updated August 1, 2013)

The CR-1 is a small, low-power, ruggedly constructed radio receiver that is finding a niche in the world of SWL’s (short wave listeners) and amateur radio enthusiasts alike.

The CR-1 is a NEW Software Defined Radio (SDR) from the designers of miniature wideband signal intelligence receivers, developed for special-operations units, and rugged business-jet data-link transceivers.

The CR-1 SDR is independent of a host PC, using embedded digital signal processing technology providing a degree of portability and performance previously unavailable to the radio enthusiast.

As one potential customer noted: “It’s an SDR with knobs, keys, and a display!”

Hardware Design Limitations:

  • The CR-1 is not controllable over USB.
  • Analog or digital IQ or IF signals are not ported to any connector.
  • LW (150 kHz - 480 kHz): The CR-1 was designed to tune down to 500 kHz.  The tuner is programmed to provide tuning to 150 kHz. However, there is no dedicated pre-selector in this range.  The IF is also in this range and signals from other bands can be heard. The CR-1 performance is not guaranteed in this range and is provided for experimental purposes. Good performance has been reported from one CR-1 owner who uses an external LW preselector.

Free: Software Upgrades:

  • SW revisions and upgrades (improvements) via Dropbox as they occur
