In the state of your soul survival depends on four things: protection from the weather (cold, rain, heat), food, water and a search party. Also in operational activities, Such as rescue operations, climbing in the squad, disaster relief, communication plays an Important role in the operation. Ability to communicate with others is vital to master the outdoors. This will be felt when we are in a condition of survival in which we must be able to provide alerts to notify or ask for help in someone who may be able to give help to us. In this material will be explained some practical ways that will communicate directly useful in outdoor activities, namely:
 |
| Morse |
 |
| Semaphores |
 |
| Radio Communications (Handy Talky) |
- Another way in a state darurat
1. Semaphores : It is a gesture in the delivery of news using a pair of semaphore flags. For long-distance delivery, to the extent that distance can still be perceived by the eye either. But at those times is now rare and almost never used anymore, although sometimes useful for emergencies.
2. Morse : Is one form of communication cues, such code combination of a long and short forms that represent all the letters, numbers and punctuation. At those times now Morse is still used primarily for emergencies (emergency condition).
Tools commonly used include:
- Whistle : This whistle commonly used form of cues given by a short sound and long sound.
- Light : It is best to light a flashlight covered with red cloth / orange so as not to dazzle the eye. Should be taken to light the sender can be seen clearly by the recipient. Alert declared by Irradiating a flash and the signs with long exposure (long).
- Smoke : Hard to be used must be kept clearly legible.
- Telegraph Equipment (Electronic) : Widely used tool at the time the telegraph was still unused. Statement of the equal sign with a whistle.
3. Radio Communications : Radio communication in the present have very important role. Broadly, the radio can be interpreted as long-distance relationship using ekektronik equipment such as SSB, walkie talkies, CB aircraft and other types of transmitter / receiver other.
Usefulness
In general it is a lot of uses of certain radio communications such as sending news from one place to another place quickly. For example:
- Radio communication by space planes.
- Communication between the search parties and outposts in opersai SAR, expedition, exploration, and so forth.
- Emergency, SOS and others.
Type - type of radio communication
Radio communications can generally be divided into 2 types, namely:
1. Communication direction
Unidirectional communication is not so absolutely necessary for students because of the unidirectional communication we can only just received the news without being able to send or post any news without being able to accept. For example, we listen to the radio board-cast or become the operator.
2. Two-way communication
Knowledge of communication is important sengatlah. For example, communication between rescue teams. For long distance once commonly used in aircraft type SSB or the telegraph (Morse code / CW), while medium-and long-distance fatherly near FM is commonly used aircraft types.
EMERGENCY COMMUNICATION
a. Signs with Smoke or Fire
Is the simplest way to tell the position with great fire and light so easily visible at night or in thick smoke and clot in the afternoon. But keep it away not to burn the forest.
b. Survival Mirror
Mirror survival is a two-sided mirror that of a rectangular metal which has two holes, one middle and one lane.
How to use:
- Hold the mirror about 10 cm in front of face
- Peek into the target object through the hole in the middle mirror so that light passing through the hole fell face mirror
- Try this condition continues to remain the object of the intended peer. Suppose the aircraft or ships.
- At that time the object will receive a flash / light reflection mirror. In fine weather this sign can be seen up to a distance of 15 kilometers. If the mirror is unusable pieces of tin cans of food such as sardines or corned beef.
c. Cloth
Used to provide a cue from land to air, can be made of white cloth, orange, or other colors that stand out, easily seen and shaped in such a way as to have an agreed meaning.
d. Body Cues
Is another technique of surface-to-air communication with the body movements that have a particular meaning.
e. Flare
Used exclusively for rescue operations in mountain
CODE TYPE OF EMERGENCY
- SOS (repeated)
SOS stands for Save Our Soul (Save our souls), is used to notify an emergency
- MAY DAY
Usually the term is used in flight, to notify an emergency / accident in the air or on land (after landing) and the immediate need of help.
- SECURITY
This code means that it will continue the message / news about safety, weather, or natural disaster
- PAN
This code means that it will continue the message / news about emergencies
