INTERNATIONAL CODE OF SIGNALS

www.hamlife.com


1. The Phonetic Codes

The underlined syllables of phonetic codes should be pronounced as an emphatic tone.

2. The Morse Codes

A dot is used as the unit of duration.
A dash(-) is equal to three(3) times the duration of the dot.
An element is ether a dot or a dash.
The space (silence) between elements is one unit. The space between letters is three(3) units. The space between words is seven (7) units.
These are dependant on WPM(words per minutes).
You should transmit at the speed you able to copy accurately.

3. The Semaphore Signals

3.1 The Calling Signals

The calling station send the calling signal "K1" to communicate with other stations. It may be made by any method of signaling.

3.2 The Answering Signals

When the answering station received the calling signal from the calling station, the answering station send the answering signal "T" to the called station. If it could not be made by the semaphore signals, the answering station should send the massage "YSZ" by any possible method of signaling.

3.3 The Ending Signals

The communications are ended by the ending signal "AR".

4. The Flag Signals

The flags of the International Code of Signals, although they represent the alphabet, are not normally used for English-language text. Instead, they are used either to give the call letters of a ship, which are allocated internationally by subdividing the alphabet in much the same way as is used for radio stations, and which are four or five letters long, or for indicating code words in the International Code of Signals.
