Applications

For example, Fldigi has been used by the Austrian Association of Test Transmitters since 2019 for the monthly OE emergency call round to broadcast emergency radio messages in digital form. The OE emergency call is used to practice in the event of a disaster.

The US Air Force uses Fldigi in its MARS ( Military Auxiliary Radio System ) program, which is used by radio amateurs for backup communication in emergencies.

The United States Department of Homeland Security (DHS) is also using Fldigi on a test basis: For example, a radio beacon in Colombia is broadcasting via Fldigi as part of the Share program.

The open source project PSKmail, which enables the transport of files and the sending / receiving of e-mails via shortwave, also uses Fldigi on its server.
