This is a version of colrdx with enhancements to connect to ON4KST chat a.k.a. "KST". KST is a chat for Amateur Radio to arrange contacts in the higher bands of the spectrum where random contacts are rare or impossible due to the very narrow beamwidth of the antennas. The chat also allows the posting of noticeable contacts a.k.a. "DX spots" that help the others estimate the conditions of propagation.

It connects to the KST server via telnet on address www.on4kst.info and port 23000.

Be aware that since the interface is telnet based your password will transit in clear thus you should choose a password dedicated to the ON4KST chat different from your other more secured passwords.

Just clone this repository

The configure script will yell if you are missing libncurses development library. In Debian distributions this is installed with:

• sudo apt-get install libncurses5-dev
• sudo apt-get install cmake

• Make a build directory inside your clone
  • mkdir build
• cd into it
  • cd build
• run cmake
  • cmake -DCMAKE_INSTALL_PREFIX=your_install_location ..
• run make with the number of threads corresponding to the logical CPUs of your machine. For example:
  • make -j8
• run make install with sudo if you install the software in the default directory
  • make install

To connect to the KST chat you need to contact the www.on4kst.info server on port 23000. Run it with your callsign in -c option and with -k option to get KST display enhancements:

• /opt/install/colrdx/bin/colrdx -c <my_call> -k www.on4kst.info 23000

To check all options run the help

• /opt/install/colrdx/bin/colrdx -h
