The HF / VHF wideband receiver FLEX-6700R Signature Series Direct Sampling receiver represents the state of the art in software defined radios. With the ability to simultaneously receive up to eight (8) different band segments on two (2) separate antennas in the most demanding RF environments, the HF / VHF wideband receiver FLEX-6700R vastly improves operator situational awareness over traditional radio architectures. Continuous frequency coverage from 20kHz to 72MHz plus 135 to 165MHz is available with up to 14MHz of instantaneous spectrum display per panadapter screen.

Interface to the radio is accomplished using Ethernet connectivity allowing for remote LAN operation today and the capability of future WAN operation from anywhere. SmartSDR for Windows, a highly integrated graphical user interface, provides real-time spectrum and waterfall displays, precise frequency management and antenna controls, and interface to a host of third party demodulation and signal analysis applications.
