AUDIO SIGNALS Radio Equipment The Clansman radio or a good old CB can be paer of the Patrols survival kit. The ranges of the different radios vary depending on the altitude of the receiving rescuer. All these factors should be considered, desert terrain, vegetation density, weather. your equipments battery strength, type of radio, and type of interference. To obtain maximum performance from radios, use the following procedures: |
Try to transmit only in clear, unobstructed terrain Since radios are line-of-sight communications devices, any terrain between the radio and the receiver will block the signal Keep the antenna at right angles to say any rescuing aircraft. Please remeber there is no signal from the tip of the antenna <DIR> <DIR> If the radio has tone capability, place it upright on a flat, elevated surface so that you can perform other survival tasks Never let the antenna touch your clothing, body, foliage, or the ground. Such contact greatly reduces the range of the signal Conserve battery power. Turn the radio off when you are not using it. Do not transmit or receive constantly. keep transmissions short to avoid enemy Patrol finding you and for depletion of battery power In cold weather, keep the battery inside your clothing when not using the radio. Cold quickly drains the battery's power. Extreme heat such as desert sun may cause the battery to explode. keep the radio and battery as dry as possible. Water may destroy the circuitry </DIR></DIR> |
| Whistles Whistles provide an excellent way for close up signalling. In some documented cases, they have been heard up to 1.6 kilometres away. Manufactured whistles have more range than a human whistle. Do not relly on your voice to communicate as you will lose it very quickly |
CODES AND SIGNALS Now that you know how to let people know where you are, you need to know how to give them more information. It is easier to form one symbol than to spell out an entire message. Therefore, learn the codes and symbols that all rescuers understand |
SOS You can use lights or flags to send an SOS - three dots, three dashes, three dots. The SOS is the internationally recognised distress signal in radio Morse code. A dot is a short, sharp pulse; a dash is a longer pulse. Keep repeating the signal. When using flags, hold flags on the left side for dashes and on the right side for dots |
Phonetic Alphabet & Morse Code

Body Signals to convey a message When in danger in a boat, wave both hands high above your head or wave clothing a whiustle is a real help to atract attention. If spotted by an aircraft and it is close enough for the pilot to see you clearly, use body movements or positions |
Panel Signals If you have a life raft cover or sail, or a suitable substitute, use the symbols shown to convey a message |
AIRCRAFT or SHIP COMMUNICATION PROCEDURES If you can contact a friendly ship or aircraft with a radio, guide the them to your location. Useing the following general voice procedure format to guide the pilot: |
Simply because you have made contact with rescuers does not mean you are safe. Follow instructions and continue to use sound survival and evasion techniques until you are actually rescued Rememeber once again - Radios, whistles, and gunshots are some of the methods you can use to signal your presence to rescuers. (Always carry an emergency whistle) |
