Microprocessor control systems, coding schemes, and modern communications equipment suggest new possibilities for the operation of HF radio systems. This paper describes a design concept for an automatic radio system, intended to overcome some of the traditional difficulties experienced with HF communications and to provide new capabilities including selective calling and automatic connectivity. The design incorporates a passive frequency selection technique using built-in ionospheric prediction data and real time monitoring of channel interference levels.
