- 5. Signal Communication – a method or means or a combination thereof of conveying information of one person or place to another except direct conversation. Means of Communication – a medium by which a message is conveyed from one person to another DEFINITION OF TERMS
- 6. Agency of Communication – A facility which embraces the personnel and equipment to provide signal communication by any particular means or combination thereof. COMMEL, Division Signal Battalion. Tactical Radio Sets – is the principal means of communication in tactical units. It use for command, fire control, exchange of information and administrative purposes between and within units
- 7. MEANS OF COMMUNICATIONS Wire – It is used as the principal means of communication in all armed forces. This means of communication embraces all equipment used for laying recovering wire, battery operated and sound-powered telephones, switch boards and teletype equipment when their use is authorized.
- 8. MEANS OF SIGNAL COMMUNICATION Radio – this means of communication is the most rapid one. It is most frequently used for maintaining command, control, contact and direction in contact. The radio has one distinct advantage over other means of communication. It has a relatively high degree of mobility and flexibitly, resulting from the fact that physical circuits are unnecessary to establish communication between radio stations.
- 9. MEANS OF SIGNAL COMMUNICATION Messenger – the use of messenger as a means of communication is preferred over the rest when maps and classified documents are to be transmitted to other operating units. Since time immemorial, messengers are have been used as a means as communication
- 10. MEANS OF SIGNAL COMMUNICATION Visual Signal – It is used to control the action of the small units. Over the years, a visual signal has been relegated to the role of an auxiliary means of communication. Any signal that is received by the eye regardless of how it is transmitted “common sense” definition of a visual signal, flags, signal flares, and smoke signals have been used throughout the ages as visual means of communication have been developed
- 11. MEANS OF SIGNAL COMMUNICATION Sound Signal – This means of communications is primarily to spread alarms. Normally it is used to warn troops of an impending hostile air, mechanized, or gas attack, Signal received by the unaided ear, regardless of the method of transmission, are sound means of communication. They may be transmitted by whistles, bugler, horns, weapons and other noise- making device. Prearranged messages are transmitted through this means.
- 12. CAPABILITIES OF THE RADIO 1. Radio communication can be used more quickly than wire communication. 2. Once mounted in the vehicle, radio equipment should be ready for use and does not require reinstallation. 3. Radio is mobile, it can be used a serial, amphibious vehicle and dismounted unit 4. Through the use of relay circuit, it communicates for a distance in case of VHF- HF. 5. it has different mode of operation such as voice radio telephony, telegraph, teletype, visual transformation and transmission
- 13. Radio is subject to equipment breakdown. Radio is subject to interference. Radio is the least secured means of communication LIMITATIONS TACTICAL APPLICATIONS Main unit is moving or operating. It is necessary to maintain radio silence. Avoid necessary transmission. Transmit only when necessary emergency
- 14. ADVANTAGES OF RADIO SPEED OF INSTALLATION – It is easy to establish than wire or other means of signal communication. FLEXIBLE – It is no fixed circuits are required to be constructed. It provides communication across impossible terrain over which is may be impractical to install wire.
- 15. DISADVANTAGES OF RADIO LACK OF SECURITY- Radio is the least secured means. It is always assumed that interception every time the transmitter is place on operation. Subject for interception radio is least vulnerable to enemy terrorist activity than wire, however, it is subject for interference from precipitation and jamming to other station.
- 16. Radio telephone procedures are a set for using a radio or telephone. It speeds the exchange of message and helps avoid errors, the rules listed below will help you use transmission times efficiently and avoid violations of communication security a. Transmit clear, complete, and concise messages, When possible write them out beforehand. b. Speak clearly, slowly and natural phrases. Enunciate each word if a receiving operator must write the message, allow time for him to do so. c. Listen before transmitting to avoid interfering with other transmission. d. Always assumed that the enemy is listening. RADIO TELEPHONE PROCEDURES

- 19. Fundamentals of tactical radio communication Radio Net – A group of several station working together in the same frequency. Call sign – Combination of characters (Letters and numbers) or Pronounceable. Net Call Sign – A call sign that identifies all radio station operating in a particular net and using the same frequency. Call – A method of establishing the communication whereby the station calling transmit the identity of the station called as well as his own identity. Pro words - Are pronounceable words that have assigned meaning to facilitate transmission by radio. Individual Call sign - this call sign Identifies a single call to any station within the net. Collective Call sign - this call sign Identifies two or more station in particular radio net but not all stations in the net.
- 20. Fundamentals of tactical radio communication CONT’N Individual Call sign - this call sign Identifies a single call to any station within the net. Collective Call sign - this call sign Identifies two or more station in particular radio net but not all stations in the net.
- 21. PROWORDS All After - the portion of message to which one refer as all that which follows. Break - I hereby indicated to separation in the next from other portion with the message. Correct -You are correct or what you have transmitted is correct. I read back - The following is my response to your instruction to read back.

Over - his is the end of my transmission to you and response is necessary. Go Ahead - transmitted not to be used together with the proword out.
- 22. PROWORDS Read back - Repeat this entire transmission back to me exactly as received. Roger - I have received your transmission satisfactorily. Say Again - Repeat all your last transmission. Wait - I must pause for a few seconds. Wilco - I have received your message, understood it, and will comply. Wait Out - I must pause longer for a few seconds. Word After - Word to which I refer follow. Word Before - Word to which I refer precedence. Out - This is the end of my transmission to you and no reply is required.
- 23. GUIDELINES FOR TRANSMISSION 1) Always write your radio message before transmitting. 2) Always listened before starting to talk so as not to interrupt other conversation. 3) Speak distinctly and enunciate each word in normal tone to allow the receiving operator time for copying. 4) Releasing the push to talk button immediately after completion of your transmission otherwise you will not hear other station.
