Data mode interfaces are commonly used for PSK31 and RTTY communication. These interfaces serve as a bridge between a computer and a radio transceiver, allowing digital signals to be transmitted and received. PSK31, or Phase Shift Keying 31, is a popular digital mode used for amateur radio communications. It utilizes phase shift modulation to encode and decode data, enabling efficient and reliable communication over long distances. RTTY, or Radio Teletype, is another digital mode that uses frequency shift keying to transmit text messages. Data mode interfaces play a crucial role in enabling these digital modes, providing a seamless connection between the computer and the radio transceiver. With the help of these interfaces, amateur radio operators can enjoy the benefits of efficient and ac...
