Applied digital communications via HF radio

Discusses a number of applications of microcomputers using automated transfers of messages between radio stations, mainly by means of packet radio techniques in the amateur radio environment. The world of amateur radio encompasses all the aspects of radio communications in a condensed form as the individual operator must know something about transmitters, receivers, antennas and propagation. The majority of radio amateurs use limited powers and compromise antennas. In spite of, or perhaps because of, their limitations, radio amateurs are steadily advancing the state of the art in applied digital communications. The author concludes by describing some of the features implemented in LAN-LINK, a software package developed for the MS-DOS personal computer family, to automate digital message handling via radio links with military and commercial as well as applications in the amateur radio environment.<
