High Speed Telegraphy
High Speed Telegraphy (HST) competitions challenge individuals to correctly receive and copy Morse code transmissions sent at very high speeds. It is most popular in Eastern Europe, where it is one of several activities collectively referred to as radiosport. Most international competitions are organized by the International Amateur Radio Union (IARU).
The first international High Speed Telegraphy competition was the HST European Championship held in Moscow, Russia in 1983. Two more HST European Championships were held; one in 1989 in Hannover, Germany and another in 1991 in Neerpelt, Belgium. The first HST World Championship was held in Sivfok, Hungary, in 1995, and a World Championship event has been held in every odd-numbered year since then. Most international, national, and local HST competitions are held in the countries of the former Eastern Bloc. Every World Championship to date has been held in Europe. While many competitors are licensed amateur radio operators, there is no requirement that competitors have a license, and many pursue the sport without one.
