3.0 History of the SG-2000
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.
The SG-2000 was conceived by SGC President Pierre Goral and the SGC Engineering
staff to meet an emerging need in HF communications for a relatively low cost, highly
reliable yet flexible communications platform which would be suited to multiple
control- point operation and would allow complete computer control if desired.
This was done after a careful study of emerging HF radio technology in the military and
government sector and with an eye to providing the users of SGC equipment with the
highest level of flexibility, not only today but in the future as well.
It was clear from the SGC analysis that to an increasing degree, personal computers
would be integrated into mobile, fixed, and sea going radio operations. In addition, a
whole new field called Adaptive Controllers was being developed for government and
military use.
The SG-2000 design project became an all-consuming effort among the team members
who studied all available information in order to provide a radio which would meet
modern communications needs. The process was to collect and analyze all available
trend information, review not only cutting edge but projected technology, and then
build the radio that would meet all of these needs.
It is interesting to note the design team's criteria:
•
The ideal radio would weigh as little as possible, under 6 kilograms would be
ideal. The radio would need to operate from any location. This meant telephone
line control for control at distances of several thousand miles, or by hard wire
