Frequently Asked Questions
01What does WPM mean in Morse code?
Words per minute, measured with the standard word PARIS: at 20 WPM one dot lasts 60 milliseconds. The decoder shows the speed it measured as an estimate.
02Can it decode Morse code with background noise?
Often, if the beeps stand out from the background noise. Unclear timing is flagged for review; heavy noise can still cause errors.
03Does it work with hand-keyed Morse code?
