The Official CR-1 Specifications Sheet released today
Introducing the New CR-1 Communications Receiver
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.
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!”
