Find all the important information about Morse code as a transmission technology here.
Morse rules
Division of tasks
Transmitting station and receiving station has:
- Recorder: dictates / writes down characters
- Transmitter: sends characters
- Observer: observes the signs
Notes on transmission
- Always in the same rhythm
- A dash should be 5 times longer than a dot
- Observe the distance between the individual characters
- Agree whether to morse with or without acknowledgement sign ( . = understood / - = not understood)
- Keep the message as short and clear as possible
- Select the means of transmission according to the distance and conditions
Means of transmission
| Day Night |
Means of transmission | Condition | Transmission range |
| T | Morse flags | clear view | 1-2 km |
| T | Arms of people | clear visibility | 500-700 m |
| T | Heliograph (mirror) | Sun | 20 km |
| T | Smoke | Calm | 1 km |
| T+N | Whistle | Calm | 500 m |
| T+N | Morse code | -- | Cable length |
| T+N | Radio | same channel | 10 km |
| N | Searchlight | clear view | 30 km |
| N | Candle lamp | clear view | 4 km |
| N | Flashlight | clear view | 2 km |
Alternative transmission methods
Painting a Morse code picture
Hide Morse code messages in the picture. For example, in the mountains, hill shapes, flowers, garden fence, etc.
Fever curve
Dots are small peaks, dashes are large ones. The page is changed when words are exchanged.
Program idea
Connection with card reading
- Two groups receive a card with a dot on it. They have to move to the dot and send a message at a predetermined time. One group sends, the other receives. They then meet again at a meeting point.
- If necessary, plan a training block for Morse code beforehand.
Post run
- Post run with various posts where the Morse code technique is taught.
- Prepare different means of transmission to try out
