What are the transceivers produced by FlexRadio Systems?
FlexRadio Systems originally produced the SDR-1000, a first generation SDR that used an external sound card as the A/D and D/A converter. The SDR-1000 was the original and first fully functional SDR marketed for ham radio use. It evolved from a simple three board stack of components initially designed to be an experimenters kit. The market acceptance was so overwhelming that improvements were made, such as adding a 100 watt PA and internal 144 MHz transverter, which made it a full featured ham radio transceiver. Since the SDR-1000 was never initially designed to be a high volume commercial product, it was superseded by the FLEX-5000 in the summer of 2007. The innovative and highly advanced FLEX-5000 was the result of taking the best features from the SDR-1000 family and using feedback from the ham community to produce a SDR hardware platform that had the capability to be completely controlled by software, which in turn produced the one of the two highest performing amateur radio availa
