This page describes my experience in installing FLDIGI on Linux.   I’ve done this on both Linux Mint, and Fedora 21.  While the steps described here outline the Fedora install, with the exception of the actual update commands (ie: yum vs. apt-get) the overall execution is very much the same.

Beginning the install:

First, make sure your distribution is up to date:

# sudo yum update

Once everything is up to date, download the nbems packages from http://www.w1hkj.com/download.html :

• fldigi – The main packet decoding software.  It converts audio signals into digital data.  More info on fldigi can be found on W1HKJ’s web site.
• flarq – File transfer application that integrates with fldigi.  It is used to pass ICS forms and other documents through fldigi over the air.
• flamp – Implements the “Amateur Multicast Protocol”.  Used to transmit one or more files in blocks.  It uses error correction to ensure each block is sent correctly.
• flwrap – a small program that encapsulates files to be sent, within identifier blocks to verify file integrity.
• flmsg – a fast simple forms management editor for quickly sending standard ARRL and ICS message  formats.

Other suggested packages:

• flwkey – simple interface to a CW key code generator
• flrig – simple rig control software supporting CIV, hamlib, rigcat and othres.  Ties directly into fldigi.
• fllog – simple contact logging program integrated into fldigi.
• flnet – Net check-in software
