The SG-2000 is a high performance, microprocessor (computer) controlled multi- mission HF SSB radio designed to meet the needs of marine, commercial, para-military, and amateur radio users through the year 2000 and beyond. The SG-2000's heritage includes the SG-705, the world's smallest commercial HF SSB, the SG-715 waterproof manpack radio, and the SG-712 EX-11 which has been proven in commercial and military applications in all regions of the world. The SG-2000 also benefits from SGC's expertise in microprocessor design, developed as the company evolved its line of fully automatic antenna couplers. SGC's fully automatic antenna couplers have been available since 1975 and the current computerized SG-230 series of couplers has been continuously upgraded to maintain technical dominance through software enhancements.
