The following article describes diagnostic and reliability aspects of amateur radio communications. The intention of precise measuring of quality and accuracy of every contact was present in ham radio from very beginning. The reports were sent and they are still used today, in many variants. In time, the tools to measure ionosphere state and propagation conditions emerged. They are fundamental for communication, especially long distance ones. The article concentrates on description of digital amateur mode, JT9. This mode is very effective, enables worldwide reach and requires simple tools.
