What is Morse Code?

Morse code is a communication system that encodes alphanumeric characters using sequences of short (dit) and long (dah) signals. Invented by Samuel Morse in the 1830s, it's still used in amateur radio, aviation, and emergency situations.

How It Works

Morse code represents each letter and number with a unique combination of dots (·) and dashes (−):

  • Dit (·) - Short signal of 150ms at 600Hz
  • Dah (−) - Long signal of 450ms at 600Hz
  • Spaces - Pauses between letters (150ms) and words (350ms)

Practical Applications

  • Amateur Radio - HF and VHF communications
  • Aviation - Navigation signals (VOR, NDB)
  • Emergencies - SOS and rescue communications
  • Education - Learning Morse code

Technical Specifications

  • Audio frequency: 600Hz (ham radio standard)
  • Speed: 5-60 WPM customizable
  • Farnsworth timing: separate character speed from effective speed
  • PARIS standard: Dah = 3× Dit
  • Formats: MP3/WAV/WebM/OGG - Output MP3 128kbps
