💡 Learning Tips & Best Practices

🎯 Learning Strategy

  • Don't count dits/dahs: Learn the sound pattern
  • Focus on rhythm: Each character has a unique beat
  • Practice daily: 15-20 minutes is better than long sessions
  • Be patient: Master each character before advancing
  • Use headphones: Better audio quality aids learning

⚙️ Settings Recommendations

  • Beginners: 18 WPM character, 5 WPM effective
  • Character speed: Never go below 15 WPM
  • Session length: Start with 5 minutes
  • Character count: Begin with 2-3 characters
  • Frequency: 600 Hz is most comfortable for most
