Fldigi 4.2.13 has been released, providing an essential Open Source tool for amateur HAM radio operators. This software facilitates the rapid calibration of sound cards to specific time signals and enables frequency measurement tests among other functionalities. By transforming a standard computer's sound card into a simple two-way data modem, fldigi allows operators to connect their amateur radio equipment—specifically SSB transceivers and FM two-way radios—to their computers via headphone and microphone jacks.
The application is particularly valuable for those wishing to communicate globally while minimizing power consumption, making it an excellent choice for emergency radio communications during natural disasters or power outages when conventional systems may fail. During the setup process, users can opt to include flarq, an ARQ specification created by the same author. This feature allows for the transfer of emails, text files, images, and binary files over the radio using a unicast, connection-based protocol that integrates smoothly with popular email clients such as Microsoft Outlook, Mozilla Thunderbird, and Sylpheed. While flarq enhances fldigi’s capabilities, it is not a requirement for the software's core functionalities.
Fldigi supports a wide range of digital modes including CW (Continuous Wave), PSK (Phase Shift Keying), MFSK (Multiple Frequency Shift Keying), RTTY (Radio Teletype), Hell (Hellschreiber), DominoEX, Olivia, and Throb, making it a versatile tool for a variety of communication needs.
In addition to these features, future updates to fldigi may include enhanced user interfaces, improved compatibility with newer operating systems, and additional digital modes to expand its functionality even further. The ongoing development of fldigi is a testament to the commitment of its developers to support the amateur radio community and ensure effective communication methods are available for operators worldwide
