LINUX USB PORT ACCESS

USB Port Access

  A USB connection is a convenient way for fldigi to control the radio PTT and tuning. To use the Ubuntu USB device file, join the dialout group:
         sudo adduser [username] dialout

Then, log out and log back in for the change to take effect.

  With some previous PPAs, the USB connection did not function unless fldigi ran with adminstrative privileges. That problem has been solved in the current archive. Also, with KA6MAL's fldigi package it is not necessary to remove the brltty background process from Ubuntu.

  After connecting a serial interface between the radio and the computer USB port, turn on the radio. To start fldigi:
         /usr/bin/fldigi

Or, click on the fldigi icon in Launcher on the desktop. Configuring Fldigi

  On the first startup, a configuration wizard opens. You can also complete this process using the fldigi Configuration Menu. Here are some settings for fldigi with a MicroHam USB Interface III:

    Audio Devices: In "Port Audio" select "USB Audio CODEC"
                             for both Capture and Playback.
    Hardware PTT: Separate serial port PTT selected using
                             RTS. ("RTS+V" Not Selected.)
    Device: /dev/ttyUSB0 selected (at the bottom of the
                             pull-down menu).

    Click on the Initialize button, followed by the Save button.

  As explained in the article on the accessibility of fldigi for Linux, when the flrig rig control program is running, HamLib is not required for rig tuning using fldigi.
