NAME¶fldigi - digital modem program for hamradio operators
DESCRIPTION¶Fldigi is a cross-platform multi-modem program for most of the digital modes used by radio amateurs today: CW, PSK, MFSK, MT-63, RTTY, Hellschreiber, DominoEX, Olivia, THOR and Throb are all supported. It can also help calibrate a sound card to a time signal and do on-air frequency measurement tests. Fldigi features basic rig control, logging, and contest operation, “panoramic” PSK decoding, a PSK Reporter client, and remote control via XML-RPC.
OPTIONS¶Long options begin with two hyphens and are handled by fldigi. The option names may be abbreviated to any unambiguous substring, and the option argument may be separated from the name by a space or equals sign, as per getopt(3).
Short options begin with a single hyphen and are passed directly to FLTK. They may be abbreviated only as indicated.
The --xmlrpc-* options are only available if fldigi was built with XML-RPC support.
Standard FLTK options¶-bg, -background COLOUR
-bg2, -background2 COLOUR
-di, -display DISPLAY
-dn, -dnd or -nodn, -nodnd
-fg, -foreground COLOUR
-g, -geometry GEOMETRY
-k, -kbd or -nok, -nokbd
-na, -name CLASSNAME
-ti, -title WINDOWTITLE
Additional UI options¶--font FONT[:SIZE]
Options useful to developers¶
The --benchmark-* options are only enabled if fldigi was built (exclusively) for benchmarking and batch decoding.
The following options should not be relied upon. They are listed here only for the sake of completeness, and may be replaced by GUI settings or removed altogether in a future version.
ENVIRONMENT¶Fldigi uses several environment variables, mainly set for child processes created by the <EXEC> macro and the notifier.
Macro variables¶The following variables are created in the environment of the child process that is forked by the <EXEC> macro. They are empty if values are not available.
Notifier variables¶The following variables are created in the environment of child processes created by the notifier.
Debugging variables¶The following variables are only used if fldigi was built with debugging support (--enable-debug), or they are only useful when debugging specific modules.
RESTRICTIONS¶Fldigi is licensed under the GNU GPL, which grants you the right to run the program for any purpose (freedom 0). However, permission to use it for the transmission of radio signals can only be obtained from the communications authority of your country. When given, this permission almost always comes in the form of an amateur radio license.
If you do not have an amateur radio license you can still have fun using fldigi as a shortwave listener. One way to do so is by using the builtin PSK Reporter client to submit realtime spots of transmitting stations; see RESOURCES below. All you need is a computer, homebrew SDR receiver, and simple wire antenna!
FILES¶Various files and subdirectories are created in $HOME/.fldigi. Some of the most interesting ones are listed below.
The following files are used if present. They must be downloaded and copied to ~/.fldigi/ by the user.
