SINCGARS FAMILIARIZATION AND OPERATION Primary Instructor: SGT SPENCER Assist Instructor: SGT LEWIS 549th MP CO

TASK: Communicate via Tactical Radio in a Secure Net CONDITIONS: Give an operational radio net with an SOI, fill device with appropriate fills, fill cable, and an operational distant station STANDARDS: Establish voice communications with the distant tactical radio/network within three minutes References: TM 11-5820-890-10-8 TM 11-5820-890-10-2 2

METHODS OF COMMUNICATION VISUAL SIGNALS (Hand signals, Semaphore) SOUND SIGNALS (Speaking from one person to another) MESSENGER (Sending another person to deliver either a written or voice message) WIRED SIGNALS (Land-line telephone, DSVT/DNVT, TA-312, TA-1) RADIO COMMUNICATIONS (SINCGARS, PRC-77, PRC-127)

PURPOSE Provide familiarization / refresher training on SINCGARS radios through conference style instruction and hands – on practical exercises. Ensure personnel are capable of operating SINCGARS radios in Frequency Hopping Modes. Ensure personnel are trained to perform both hot and cold start net openings.

SINCGARS ASIP Keypad [CMSC] (#1) used to scroll COMSEC keys TEK used in channels 1-5 and may be used in channel 6. KEK used in chan. 6. [RCU] (#2) used to convert to a remote system. Can operate up to 4 km away. [SYNC] (#3) used during FH to sync RT to net. [FREQ] use to call channel database to display. “FILL” means channel is empty. With Function switch in SQ. [FREQ] and #7 used to set backlights. [ERF/OFFSET] key not recommended. Use air net synchronization instead. [OFST] is a SC anti-jam procedure. [SA] & [GPS] keys not used at this time.

SINCGARS ASIP Keypad [DATA] key (#4) allows you to set data rate [CHG] (change) key in conjunction with [DATA], [OFFSET] or [CMSC] keys to scroll through data/options. [CID] key is not used at this time. [LOUT] key rarely used. [TIME] key used to enter Julian date and sync time. [BATT/CALL] key used to set and check battery life in a dismount radio. Also used for commo between RT and RCU. [STO] key used to place data into memory. [LOAD] key use to load data into holding memory and retrieve data from permanent memory. [CLR/MENU] key is used with other keys to delete entries or stored data.
