fldigi for Windows

A Solid Software for Radio Amateurs to Learn

Fldigi is a software tool that lets you make a radio station out of your computer. It enables you to read incoming signals, control the transmitter, and tune high-frequency propagation. All digital modes are supported by the program, including CW, MFSK, PSK, Hell, RTTY, Olivia, DominoEX, and Throb. The tool’s primary functions are sound card calibration or carrying out frequency measurement tests. Fldigi depends on your computer’s sound card to output and input audio-frequency signals. It functions in tandem with a conventional HF SSB transceiver while using serial port connections to control the radio.
