NOTE: Tuning down to 150 kHz (was 500 kHz) now included in all CR-1s.  Optional Internal Lithium-Ion rechargeable battery avialable on all CR1's.
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!”
