Digital Modes are a way of operating radios from the keyboard. You can type and see what the other person is typing. It also controls the transmitter, works on different modes, and provides features for easier usage. These modes enable conversation similar to voice or Morse code. Fldigi enables users to utilize these digital modes.

For that reason, amateurs who love playing with digital modes will enjoy the tool Fldigi is. The program works in conjunction with a radio transceiver, and it uses your sound card. This program is multi-mode, so it operates various popular digital modes - you won’t ever have to switch programs.

In Master Volume, you can set the audio level for transmission. Fldigi works on reducing noise and making the messages clear. Then you record the messages and work on decoding them.

There are three main panes in Fldigi’s main window - receive, transmit, and waterfall, as well as many control features. In the receive pane, you will see the text from incoming signals and your transmitted text as well. In the transmit pane, you will type the text you want to send. The waterfall shows you the signal strength to frequency.

Although this may sound like a lot, Fldigi is easy to learn. Amateur radio operators will enjoy playing with different basic and advanced options it offers as they work on their messages.
