Frequently Asked Questions
What speed should I use to learn Morse code?
Start at 5–10 WPM so you can clearly hear each dit and dah. Many trainers recommend the Koch method — learning at full speed (20 WPM) for just 2 characters at a time, rather than slowing down. Our practice tool supports both approaches.
What tone frequency do real radio operators use?
Most operators prefer 600–750 Hz. Lower frequencies (400–500 Hz) sound softer and are sometimes used for extended listening. The default 680 Hz is a good middle ground — clear and easy on the ear over long sessions.
How is WPM calculated in Morse code?
WPM is based on the word PARIS, which is exactly 50 units long including the trailing gap. At 15 WPM, one unit = 60 ÷ (50 × 15) = 0.08 seconds (80 ms). A dot is 1 unit, a dash is 3, gaps between letters are 3, gaps between words are 7.
Can I use this to learn Morse code?
Yes — type a letter or word, hit play, and listen repeatedly until you recognise the sound pattern without looking at the screen. Combine with the alphabet page for visual reference and the Morse code simulator to test yourself.
