Equipment for an automatic transmitter identification system (ATIS)

Increased use of radio channels is possible if fraction-of-a-second data messages are used to replace voice identification now used operationally and to satisfy FCC procedural rules. Recently developed equipment for the ATIS function is simple, reliable and low cost, so that it can be considered for universal use. The modulation, coding and circuit design technique used will be described as well as some applications and experimental results. This work is related to universal ATIS as explored in FCC Docket No. 20351, and comments will be offered on maximization of user benefits which might result from adoption of appropriate ATIS technical standards.
