Installing and Configuring
Flrig on Ubuntu

 

   This page is a supplement to the article on rig monitoring with flrig for Linux.

   Flrig source code is available from W1HKJ's Download page. Building the flrig executable from source code requires some Linux experience as you need to get additional files. Installing a package for flrig is easier.

Installation of an Flrig PPA

   Recent versions of Flrig are available in the Personal Package Archive (PPA) developed by Kamal Mostafa, KA6MAL. Kamal is a Canonical software engineer who has developed a number of PPAs for popular amateur radio programs.

   There is a link at the bottom of the W1HKJ Download page to Kamal's site as well as a link with instructions for installing flrig for Ubuntu using the PPA. Flrig is in his fldigi repository:

     sudo add-apt-repository ppa:kamalmostafa/fldigi
     sudo apt-get update
     sudo apt-get install flrig

 

Removing Old Versions of Flrig


   If you have previously built flrig from source code or used an executable binary file from W1HKJ (no longer available), it is probably in the /usr/local/bin directory. KA6MAL explains why you must remove the old file before the executable from KA6MAL in /usr/bin will run.

Configuring Flrig

   Connect the interface cable to the computer USB port, turn on the radio, and open flrig:

     /usr/bin/flrig

 

   The online Help menu explains in detail how to configure flrig, and some of the features are described in a separate article on flrig accessibility.

Here is the radio connection configuration I use with a MicroHam USB Interface III (Flrig Config menu > Xcvr select):

     Rig: Icom 746PRO
     PTT via RTS
     RTS + 12 V Not Selected
     DTR + 12 V Not Selected
     Serial Port: /dev/ttyUSB0
                 (at the bottom of a long pull-down menu)
     9600 Baud to match the setting in the radio.

Click on the Initialize Button, and exit flrig.

Using Flrig with Fldigi

   Fldigi and flrig can work together. Fldigi for Linux is described in two separate articles, one about the user interface and accessibility and the second gives an example of how to install fldigi on an Ubuntu system.

   You can start either program first. For example, with flrig open as described in the previous section, open a second terminal window (Ctrl-Alt-t):

           /usr/bin/fldigi       

A configuration wizard walks you through the setup the first time fldigi is opened. Or, you can use the Configuration menu.
