Getting Started with Fldigi – Including Flmsg and Flwrap


Select an appropriate form. This can be anything for practice.


  • When practicing or testing with Flmsg, it is standard practice to note somewhere in the form that the transmission and message is a “test,” “practice,” or “drill.”  Someone may mistake the transmission for a real message. In the case of an actual event, this advice should obviously be disregarded.

Fill out the form populating as many fields as desired.

At times, the byte count and transmit time in the status line won’t properly update. Click the * to refresh.

When ready to transmit, open Fldigi if it is not already.

Click AutoSend .

Transmission will NOT begin until the file is saved.


  • If the transmit time is too long, checking Compression in the status line will save some time.

You will be prompted to save the report data file. Transmission will NOT begin until the file is saved.

Enter a File name.

Click Save.

Once the file is saved, transmission will begin automatically.

Flmsg will use Flwrap to generate the data file. The file will be passed to Fldigi and transmitted automatically. You will not see any changes or indication of transmission in Flmsg. However, do not close Flmsg until the transmission is complete otherwise the transmission will be terminated.

All information in the “Transmitting – Fldigi” section applies.

Transmission will autostop when completed. No need for the receive notation (^r) as it is automatically inserted.


  • To retransmit an Flmsg form, in Flmsg click FileOpen. The default save location is C:\Users\Username\NBEMS.files\ICS\messages. Next to file name, click the drop down and select All Files. Click the report data file to resend. Click Open. In Flmsg (with Fldigi open), click AutoSend.
