COMMRADIO CR1A Communications Receiver / SDR FM, WFM, AM, USB, LSB, CW

*Latest CR1A Version*

From Universal radio.com:

TheCommRadio CR-1acommunications receiver is a true SDR (software defined radio), but doesnotrequire a computer. Enjoy the benefits and performance of state-of-the-art SDR, but in a conventional radio package. The CR-1a SDR is independent of a host PC, using embedded digital signal processing technology that provides a degree of portability and performance previously unavailable to the radio enthusiast.

Coverage includes: 500 kHz-30 MHz, 64-260 MHz and 437-512 MHz in AM, SSB, CW, WBFM, NBFM modes. (Longwave 150-500 kHz available with reduced performance). 64 memories (8x8) are available. Memory and spectrum scanning are available on HF. The incredible performance is combined with exceptional portability and ease of use.

The radio may be powered via USB or 6-18 VDC input (2.1 x 5 mm diameter - center pin-positive). In both cases the Li-ion battery will be recharging, even when the radio is in use. The USB port is also available to update the firmware over the Internet and provide I/Q output. There is a quality speaker built into the bottom panel (... thus the large feet).

All thistop-shelfAmerican technology and capability is housed in a solid, butcompact, metal case measuring 5.64 W x 2.43 H x 6.10 D inches that weighs 1 lb., 12 oz. This radio can be charged via USB cable.

The CR-1a is similar to its the predecessorCR-1. I-Q data and radio controls via USB port has been added and the display is now amber rather than green.
