N9LYA Techical Guides 11 - Amateur Radio Digital Modes

Digital-mode problems rarely stay in one layer. A failure may begin in an application setting, serial device, TCP link, audio level, modem, radio menu, feed line, propagation path, or remote station. Amateur Radio Digital Modes teaches operators to follow the complete signal path. It covers packet concepts, station interfaces, AX.25, store-and-forward networks, Winlink-style paths, mode selection, audio and RF discipline, and practical troubleshooting across software and hardware boundaries. The second edition includes eight instructional diagrams and a practical station setup and on-air checklist. Best for: packet operators, emergency-communications volunteers, Winlink users, and radio amateurs building or repairing digital stations.
