How does an electronic keyer help form good Morse code characters?
- A By ensuring that the dots and dashes have the same amplitude
- B By regulating the lengths of the dits and dahs
- C By eliminating key clicks
- D By improving the tone of the CW signal
Correct answer: B — By regulating the lengths of the dits and dahs. From the official ISED question bank, verified word for word.
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.
