Fldigi along with flmsg and flrig (for CAT control of your radio) are used almost exclusively during emergency communication deployments. It's best to keep them updated to the latest version to prevent problems or compatibility issued in a real event.
All three can be used on Windows, Linux and MacOS platforms, making it very easy to use.
