Downloading and Installing tk2
on Linux-Based Systems

Version 1.1

tk2 runs in the X Windows System graphical environment and is independent of your desktop manager (e.g., KDE or Gnome). tk2 has been tested on a 1400 MHz AMD Athlon® based computer running Red Hat® Linux® 8.0 with kernel 2.4.18-27.8.0. and Tcl/Tk version 8.4, patchlevel 8.4.1.

This is experimental software and probably contains defects. It remains under development. When available, newer versions of tk2 will be made available for download at this web site.

Downloading and Installing tk2 for Linux

  1. You will need Tcl/Tk version 8.4 or later. At the time this is being written, version 8.4 is new and is not yet available in RPM format. Therefore, you will have to download the binary file and run the script.

    View the installation notes for Tcl/Tk version 8.4. Download and install the free Tcl/Tk software from: . (The file size is about 10.4 MB.)

  2. Create a new installation directory on your system, e.g.,
    mkdir /home/username/tk2
  3. Download the gzipped version of tk2, tk2-1.1.tgz into the installation directory you created earlier.
  4. Untar the file after downloading it:
    cd /home/username/tk2
    tar -zxvf tk2-1.1.tgz
    This will create a new subdirectory, named tk2.1.1 and place the files there.
  5. Define and export tk2, a new environment variable to point to the installation subdirectory just created.
    export tk2
    To make the change permanent, you must add the two lines above to your shell's profile, e.g., /home/username/.bash_profile if you use the bash shell.
  6. Remove the .tk2rc configuration file if you have one from a previous installation.
  7. To ensure the tk2 environment variable is made known within X Windows, you should logout, login again, then restart your graphical user interface before using tk2 for the first time.


  1. Make sure your serial port has both read and write permissions for the user who will run the program.

    For example, I use /dev/ttyS1 as the serial port to connect the radio. If I type in a console window:

    ls -l /dev/ttyS1
    the output shows the permissions:
    crw-rw-rw-    1 root     uucp       4,  65 Aug 15 06:40 /dev/ttyS1
    Notice that /dev/ttyS1 is readable and writeable by everyone (user, group, and others).

    Login as root or run the su program to assume root privileges. Then, change the permissions and exit.

    chmod   ugo+rw   /dev/ttyS1
  2. Be sure to read a memory image from your radio and save it in a template (.tr2) file as a backup before making any changes.
  3. See the Release notes.
  4. tk2 presumes the wish windowing shell is in your PATH.
