The World Morse Code championships are fiendishly competitive. Contestants from many countries travel to Tunisia, where they face each other across tiny tapping machines in a competition hall silent but for the clicking.

Belarusians win almost every time, with stiff competition from Russia and Romania. But maybe this year it will be the Japanese or Kuwaiti competitors.
