PURPOSE
Provide familiarization/refresher training on SINCGARS/ASIP radios through conference
style instruction and hands-on practical exercises. Ensure personnel are capable of
operating SINCGARS/ASIP radios in both single channel and frequency hopping
modes. Ensure personnel are trained to perform both hot and cold start net openings.

Why SINCGARS? • Improved capabilities/reliability over VRC-12 series FM
radios
• Integrated COMSEC (means that the COMSEC circuitry is
built into the radio and requires no external devices)
• Compatibility (50 kHz channels)
• Electronic signature reduction
• More channels
• Fault identification
• Digital or analog inputs
• Frequency hopping

SINCGARS/ASIP HUB (HOLD UP BATTERY)
The BA-5372/U (pictured) is a 500 milliampere-hour, 6-volt battery, which provides memory back up power for over 60 applications, including a wide variety of tactical and strategic communications-electronics equipment, the most significant being the Single Channel Ground and Airborne Radio System.

![Page 15: Commo Section 1st Battalion, 109 th FA SINCGARS/ASIP FAMILIARIZATION AND OPERATION](https://reader031.vdocuments.us/reader031/viewer/2022012404/56649e7d5503460f94b7f53e/html5/thumbnails/15.jpg)
SINCGARS/ASIP HUB (HOLD UP BATTERY)
WARNING!! ONLY USE 6 VOLT BATTERY
HUB insert will be inserted in the same place as Manpack battery (BA-5590). A capacitor inside the radio allows only
15 minutes for an operator to replace HUB with a BA-5590, if radio will be used in a dismounted configuration

TIME and the SINCGARS/ACIP RADIO
Why do you need correct/accurate time in your radio?Answer: To frequency hop to at the same time as other radios on the net
What is the preferred time to put in your radio?Answer: DAGR Time
Answer: Use another radio that is communicating on the net to get a manual time hack
What is a “field expedient” method of attaining the proper time to put in your radio?
![Page 28: Commo Section 1st Battalion, 109 th FA SINCGARS/ASIP FAMILIARIZATION AND OPERATION](https://reader031.vdocuments.us/reader031/viewer/2022012404/56649e7d5503460f94b7f53e/html5/thumbnails/28.jpg)
JULIAN DATE
What kind of date is used when loading time in your radio?Answer: Julian Date, which is a number that represents the day of the year, i.e. 1 February is Julian Date 32
You will only use the last two digits of the Julian Date when inputting it into a radio
Example if since 1 January is Julian Date 001 and 11 April is 101, then you will input into a radio for 11 April a Julian date of 01
Answer: 06, see next slide
Using the example above, and the date is 16 April, what would you input in to a radio??

Frequency Hop DefinitionsLoadset: defined as all of the COMSEC keys (TEK and KEK) and FH data (hopset, TSK, and net ID) required to load all six channels of the SINCGARS radio.
• TEK: Traffic Encryption Key, encrypts the traffic sent
• KEK: Key Encryption Key, encrypts other keys for transmission and storage
• Hopset: the frequency pool that will be used given a frequency hop ID number
• TSK : transmission security key, determines the pattern in which the radio selects frequencies to hop
• Net Identifier: is a three digit code that controls where in the random frequency sequence to begin hopping
![Page 32: Commo Section 1st Battalion, 109 th FA SINCGARS/ASIP FAMILIARIZATION AND OPERATION](https://reader031.vdocuments.us/reader031/viewer/2022012404/56649e7d5503460f94b7f53e/html5/thumbnails/32.jpg)
FH DEFINITIONS cont
• Lockout: frequencies not to be hopped on will be locked out.
![Page 33: Commo Section 1st Battalion, 109 th FA SINCGARS/ASIP FAMILIARIZATION AND OPERATION](https://reader031.vdocuments.us/reader031/viewer/2022012404/56649e7d5503460f94b7f53e/html5/thumbnails/33.jpg)
CUE CHANNEL
• “911”
• If outside the net a radio operator must call this station first
• Designated channel used when caller can not frequency hop or lost contact with FH Net
• Only NCS loads CUE frequency - other operators load as required
![Page 34: Commo Section 1st Battalion, 109 th FA SINCGARS/ASIP FAMILIARIZATION AND OPERATION](https://reader031.vdocuments.us/reader031/viewer/2022012404/56649e7d5503460f94b7f53e/html5/thumbnails/34.jpg)
CUE PROCESS
• Operator: Load CUE Freq., Set Chan to CUE; Mode to SC;
COMSEC to PT; Presses Push to Talk (4-5 secs). Go back to CT if possible.
• Receiving NCS: sees “CUE” in RT Display and hears a tone on the speaker/handset.
• NCS Changes to CUE. Responds in CT.
• The NCS loads the CUE frequency always, but the Operator only loads the CUE frequency when necessary.
![Page 35: Commo Section 1st Battalion, 109 th FA SINCGARS/ASIP FAMILIARIZATION AND OPERATION](https://reader031.vdocuments.us/reader031/viewer/2022012404/56649e7d5503460f94b7f53e/html5/thumbnails/35.jpg)
MANUAL CHANNEL
• “Engineering channel”
• Designated channel used for transmission and receipt of Electronic Remote Fills (ERFs)
• ERF contains FH data (Hopset, Net ID, and FH timing) and sync time necessary for frequency hopping operations
• ERF does not send COMSEC
• ERF will only be used when no DAGR or vehicle with the proper time can be used. LAST RESORT!!
![Page 36: Commo Section 1st Battalion, 109 th FA SINCGARS/ASIP FAMILIARIZATION AND OPERATION](https://reader031.vdocuments.us/reader031/viewer/2022012404/56649e7d5503460f94b7f53e/html5/thumbnails/36.jpg)
LOADING NET ID INTO SINCGARS/ACIP RADIO
1. Turn Function to Load
2. Press MENU till you see MODE
3. Press CHG till you see FH
4. Press Menu till you see CHANNEL
5. Change channel by pressing the corresponding number (0-7, 0 for MAN, 7 for CUE)
6. Press FREQ, then MENU/CLR
7. You will see F _ _ _ (net ID, 3 digits)
8. Enter the net ID (000-999), then press STO

WAYS TO OPEN RADIO NET
HOT START METHOD• Most preferred method• Operators load all fill
data from ANCD• Operators place radio in
Late Net Entry or input time manually to enter net.
• Operator training heavy
COLD START METHOD• Least preferred method• Operators load
COMSEC, MAN, and CUE Freqs
• NCS training heavy
![Page 38: Commo Section 1st Battalion, 109 th FA SINCGARS/ASIP FAMILIARIZATION AND OPERATION](https://reader031.vdocuments.us/reader031/viewer/2022012404/56649e7d5503460f94b7f53e/html5/thumbnails/38.jpg)
COLD START NET OPENING
• Used in situations where the NCS desires to bring all operators into the net at exact time.
• Requires greater planning and preparation by the
NCS
• Pre-load RT with COMSEC only
• Electronic Remote Fill (ERF)-electronically updates FH data of net members and transmits sync time for cold start net openings.

ERF Radio Procedure
• Unknown Station: Places “Cue Call”
• (On Cue Channel) NCS: Unknown station this is Arrowhead 3, over.
• Unknown Station: Arrowhead 3, this is Arrowhead 9, request permission to enter the net, over.
• NCS: Arrowhead 9, Meet me on MAN, over.
• Unknown Station: Arrowhead 3, Arrowhead 9, Roger, out. (Switch to MAN)
• NCS: Arrowhead 9, this is Arrowhead 3, stand by for ERF, store on
channel 1, meet me on channel 1, over. (NCS sends ERF, then goes to channel 1)
• Unknown Station: Arrowhead 3, this is Arrowhead 9, Roger out. (Standby until NCS sends the ERF, Wait for Display to show "HF XXX“, then STO in designated slot) Unknown channel switches to designated channel and does radio check with NCS

PASSIVE LATE ENTRY
• In FH Mode, must be within 4 seconds to sync, but can be pulled into the net within 1 minute difference
• Built-in capability bring radios back into proper time
• Do not transmit while in the Late Net Entry mode!
![Page 43: Commo Section 1st Battalion, 109 th FA SINCGARS/ASIP FAMILIARIZATION AND OPERATION](https://reader031.vdocuments.us/reader031/viewer/2022012404/56649e7d5503460f94b7f53e/html5/thumbnails/43.jpg)
PASSIVE LATE ENTRY
(1) Note lack of traffic on net.
(2) Press [FREQ] on RT keypad; display reads "F XXX.“
(3) Press [SYNC] on RT keypad; display read "LF XXX.“
