Samuel Morse 
Nowadays high speed telegraphers can use the code and operate at a significantly higher level than the former “professionals”. They can receive and transmit it with such a high speed, where the weight of one basic element, a dit is only a matter of milliseconds. It is worth listening to the sample files available under the “Records” tab, which gives examples of the telegraphers’ exemplary skills.
On the HST World Championship the participants, from 4 female and 5 male categories, can try their skills and knowledge in the following 4 competition events:
Receiving tests
Receiving telegrams of letters, figures and mixed characters (letters, figures and other marks such as full stop, comma, slash, question mark and equation mark). Competitors can make a maximum of 10 attempts with different speeds, each type but only 3 of the received telegrams – freely chosen by the participant – are corrected and used to calculate the final result. Every telegram is 1 minute long, it may consist up to 5 reception errors to stay valid. The speed can be adjusted with 10 characters per minute steps.
Transmitting tests
Transmitting telegrams of letters, figures and mixed characters (letters, figures and other signs). Each transmission test is 1 minute long, and it can consist a maximum of uncorrected 3 mistakes. There are only 4 attempts possible, within the available 15 minutes counted from entering the transmitting site.
Rufz
Callsign receiving, using the RufzXP program. If a participant copies a callsign correctly, the speed increases, otherwise it decreases. The higher the speed is, the more points a callsign is worth. One attempt is made up of 50 callsigns, and each participant can make as many as 2 attempts. (www.rufzxp.net)
Morse Runner
The participants use a real, on-air contest simulator program where there are 4 stations calling simultanously. One session is 10 minutes long, each participant can make as many as 2 attempts. (http://dxatlas.com/MorseRunner/ settings under the “Rules” tab!)
The results are announced by categories, by competition events and overall.
