In the unwinder body, the unwinder
string runs under a round plastic clip on the bottom plate. This keeps the string attached to
the unwinder, and the radiosonde attached to the balloon.
To prevent the string from getting tangled in the clip during the sounding, make sure
that the round plastic clip is level with the unwinder bottom plate.
If the clip is bent up, bend it gently back to level position.
