Digital modes refer to various methods of transmitting data using digital signals, often in the context of radio communication. These modes convert information into binary code, allowing for efficient and reliable communication over long distances. Common digital modes include PSK31, FT8, and RTTY, each with unique characteristics suited for different applications. In digital modes, data is typically sent as a series of tones or signals that can be decoded by compatible software or hardware. This technology is widely used in amateur radio, enabling operators to communicate even in challenging conditions, such as low signal strength or interference.
