Study Notes
Radio Transmission Types
- Individual, Private or I-Call: Direct communication between two radios without a talkgroup; can be intercepted by radio scanners.
- E.P25 Conventional: A digital communication mode; does not use radio systems for transmissions and does not usually communicate with dispatch.
- Radio Identification Number (RID): Unique number assigned to each radio; transmitted during Push to Talk (PTT) to identify the sender and can be displayed on receiving radios.
Communication Systems
- Repeater Function: Enhances communication range by receiving and re-transmitting signals on different frequencies.
- Simplex Mode: Allows radios to communicate directly on the same frequency without a repeater; suited for short-distance communication.
- System or Zone: A grouping of talkgroups/channels to streamline communication and reduce misunderstandings.
Authorized Signals and Codes
- 10-4: Acknowledgment received.
- 10-7: Out-of-service status.
- 10-8: In-service status.
- 10-10: Available while previously engaged with other officers.
- 10-12: Caution, sensitive information may be overheard.
- 10-23: Arrival at scene; critical for dispatcher communication.
