Comment un manipulateur électronique aidet-il à former de bons caractères en code Morse?
- AEn améliorant la tonalité du signal CW
- BEn assurant que les points et les traits aient la même amplitude
- CEn assurant le rythme des points et des traits
- DEn éliminant les claquements de manipulation
Correct answer: C — En assurant le rythme des points et des traits. Question tirée de la banque officielle d'ISDE.
Why
An electronic keyer helps form good Morse code by automatically controlling how long each dot (dit) and dash (dah) lasts, ensuring they stay consistent with the rhythm you set. The full explanation — and one for every question — is in Pro.
