See the steps below for instructions on how to make a hanger board out of the radiosonde cardboard package. See also the video at

To make the hanger board, you need the following items:

  • Radiosonde handling box cardboard package
  • Scissors
  • Some string. The string used with the hanger board must have a diameter of > 1.5 mm and the strength must be 250 … 350 N.
  1. Cut the radiosonde cardboard package to one whole piece that is big enough to make a hanger board.
  2. Make 1 hole at one end of the hanger board, 4 holes at the other. Make the 4 holes so that 2 holes are on top of each other.
  3. Tie a string on the unwinder hook.
  4. Thread the string through the 4 holes so that the unwinder is firmly attached to the other end of the hanger board.
  5. Pull the same string through the hole at the other end of the hanger board and attach the string to the parachute. The string now runs across the hanger board.
