Study Notes
Radio Communications Procedures
- This course covers radio use and procedures, including discussion and demonstration.
Objectives
- Operate and understand functions of assigned radio equipment
- Identify the ABC2 Rules of Radio Transmission
- Discuss three methods of improving transmissions during emergencies
- Describe how to initiate and acknowledge radio transmissions
- Apply Interoperability principles and appropriate use of plain language
- Appropriately use the Phonetic Alphabet
- Identify five effective radio/microphone techniques
Radio Equipment
- Portable Radios: handheld receiver-transmitter using a battery as a power source and integrated antenna; limited range (approximately 1-mile)
- Mobile Radios: receiver-transmitter mounted inside a vehicle; powered by the vehicle battery (power system) which increases the effective range; higher antenna also increases range
- Trunked Radio Systems: allow multiple users to operate on fewer frequencies; frequencies are assigned to tower sites; importance: radio spectrum is very busy and limited
- Conventional systems: use radio-to-radio (direct) communication or a system of repeater sites; repeaters use more powerful radios and taller towers to receive and repeat transmissions
ABC2 Rules of Radio Transmission
- A: ACCURACY - get the desired information to the receiving party without errors
- B: BREVITY - avoid unnecessary or repetitious words
- C: COURTESY - respect reflected in tone of voice
- C2: CLARITY - ability to be understood; say what is expected in the proper format; speak clearly and concisely
Improving Transmissions during Emergencies
- Minimize noise around you (wind noise, screaming, etc.)
- Maintain composure and keep calm during stressful situations
- DO NOT shout (over-modulates the microphone and disrupts communications)
Initiating and Acknowledging Radio Transmissions
- When initiating traffic, state your badge number and then the identifier of the person you are trying to contact
- Always provide your location when initiating contact or when called or when going out on a stop or incident
- Acknowledge radio transmissions directed to you by saying "understood", using the appropriate 10-code, or identifying yourself by badge number
Interoperability and Plain Language
- Use plain language for multi-agency, multijurisdictional, and multi-discipline events to improve interoperability
- Avoid using private codes or terminology during these events
- Be aware that language or terms used may be unique to one jurisdiction or discipline and may not be common to others outside of that group
Phonetic Alphabet
- Used to improve clarity and understanding over the radio
- Law Enforcement in Missouri generally uses the Police (LAPD) Phonetic alphabet (A-Adam, B-Boy, C-Charles, etc.)
- Some agencies may use the International (military) alphabet (Alpha, Bravo, Charlie, etc.)
Effective Radio/Microphone Techniques
- Microphones are sensitive; position the microphone at a 45-degree angle to avoid picking up breath sounds and hold the microphone one inch from your lips
- LISTEN to make sure nobody else is talking; LISTEN for dispatch to sign off
- THINK before you SPEAK; collect your thoughts before calling to avoid dead air or verbal signs
- Conventional radio repeater systems have a slight delay in keying; wait a few seconds to allow the electronics to catch up
- The location of your radio antenna will affect your transmission; avoid blocking yourself by parking too near buildings, under power lines or overpasses
