Recharging Batteries
A battery will be fully discharged after 45 days if left attached to a radio. It is
recommended that the radio be stored without a battery attached or that the battery
be recharged every 5-6 weeks. If the radio is stored without an external battery, the
HUB will have to be recharged every 60 days.
The HUB is recharged by attaching a fully charged battery for up to 48 hours. For
batteries not attached to a radio, it is recommended to recharge the batteries every
12 weeks. If the HUB goes dead, the PJC (Private JOSEKI Component) will be
deleted. With no PJC, the radio can only operate in Plain Text Line of Site mode.
The radio display flashes “NOPJC” in the upper right. The PJC can be attained from
the COMSEC custodian. The short title is USKAE B9500 880091.

Receiver-Transmitter
Unit Description (1)
Receiver-Transmitter Unit Description and Capabilities.
The JEM: JTRS (Joint Tactical Radio System) Enhanced MBITR (Multiband
Inter/Intra Team Radio) operates from 30 to 512 MHz in AM, FM, and SBPSK
(Shaped Binary Phase Shift Keying) modulations in either 5 or 6.25 kHz tuning steps
with 25 KHz channel bandwidth, 12.5 KHz in narrow band, and 5 kHz in ANDVT
(Advanced Narrowband Digital Voice Terminal). The radio is compatible with KY57/58 VINSON at 16 kbps, KYV-5, FASCINATOR (FED-STD-1023) at 12 kbps, KY99/99A ANDVT at 2400 bps, and SINCGARS cryptographic systems. Therefore, the
radio is a Controller Cryptographic Item (CCI) when un-keyed.
Operating Modes:
Single Channel LOS (AM & FM): 30 - 512 MHz, 25 kHz BW, 12.5 kHz BW in PT FM
only.
•
•
•
•
SINCGARS: 30 - 87.975 MHz, 25 kHz BW
HAVEQUICK: AM, 225 to 399.975 MHz
ANDVT: SBPSK, 30 - 512 MHz, 5 kHz BW
HTW (High Throughput Waveform): CPM (Continuous Phase Modulation) 30
- 512 MHz, 25 kHz BW at 56 kbps.

Receiver-Transmitter
Unit Description (2)
Receiver-Transmitter Unit Description and Capabilities continued.
Channels: 256 programmable channels 16 groups of channels, 16 channels per
group.
Power output: Programmable on a channel by channel basis to 0.1, 0.5, 1, 3 or 5
watts (FM & ANDVT), 1, 3, or 5 watts (SINCGARS) or 1 or 5 watts (AM and
HAVEQUICK)
Comsec: Can hold 20 Traffic Encryption Keys (TEK), 1 Key Encryption Key (KEK),

Repeater Delay disables the receive circuits of the radio for a moment after
the PTT switch is released. This prevents the radio from receiving its own
transmission from the repeater. The choices are NONE, 0.2, 0.4, 0.6, 0.8,
and 1.0 second. Set to NONE for normal operation.
Fade Bridge: If the signal is lost or fades during transmission, crypto
synchronization is lost. Setting the FADE value forces the encryption chip to
maintain synchronization for the selected period of time. When the signal is
received again, the radio does not have to re-synchronize. Choices are 0, 1,
2, 3, & 4 seconds.
Phase is used to set the length of the initial bit synchronization pattern
transmitted by the radio. The sync pattern is used to sync the clocks of the
transmit and receive radios. Weaker stations or operating through repeaters
the value may need to be increased from default. Choices are .256, .384,
1.06 seconds, and Off.
Squelch is used to silence unwanted background noise. Squelch can be
raised if background noise is higher then normal or it can be lowered to
receive weaker stations. The default setting is 3; the range is 0 to 7.

Characteristics & Definitions (1)
• Operates in the VHF-Low band from 30 to 87.975 MHz
•
25 kHz channel spacing
•
2320 possible frequencies
•
Hopping rate of 100 frequencies per second

SINCGARS FH
Characteristics & Definitions (2)
• 1000 Net IDs
• Loadset, Lockouts & ESETs
• VINSON or KYV-5 COMSEC
• Hot Start Net Opening
Net IDs (000-999) are used to divide the Hopset in multiple networks by changing
the starting point in the Hopset. There are 1000 net IDs per TSK. A SINCGARS
Loadset can have 1 to 6 TSKs.
Lockout set is a set of frequencies that are not allowed in the Hopset. For example,
civilian TV stations that; exist in the SINCGARS operational range.
An ESET (Electronic Set) contains SINCGARS FH data, a TSK, and a net ID.
A SINCGARS Loadset contains up to five TEKs, one KEK, six ESETs, and any
Lockout sets. A Loadset is loaded into the radio in one-step using and AN/CYZ-10
or an AN/PYQ-10 (SKL). Sometimes this is referred to as an ICOM Fill, (Integrated
COMSEC Fill).
Hot Start Net Opening is a method of entering a SINCGARS FH Net by loading a
radio with the FH Loadset and accurate time. All radios in a SINCGARS FH net
need to be within 4 seconds of Net Control time.
4
SINCGARS FH
Characteristics & Definitions (3)
• Electronic Remote Fill (ERF)
•Manual & CUE Frequency
• Cold Start Net Opening
• Late Net Entry (LNE)
Electronic Remote Fill (ERF) is a procedure by which the net master station Cold
starts or updates a FH net by transmitting the Hopset to net member radios. ERF is
used when a member’s radio is more then 60 seconds off net time. The JEM can
only receive an ERF, not transmit. The ERF must be sent using an AN/PRC-119,
AN/PRC-117, AN/PRC-152, or similar radio.
The Manual frequency is a single channel frequency used for the receiving and ERF
or Cold Start Net Opening. The CUE frequency is a single channel frequency that
allows a radio not in a SINCGARS FH net to contact the MASTER station of the
SINCGARS FH net.
Cold Start Net Opening is a method of opening a SINCGARS FH net where member
stations load the FH Loadset then the Master station transmits the FH data and net
time.
Late Net Entry (LNE) is a method to enter or re-enter the FH Net when radio Time of
Day (TOD) has slipped by more than four seconds, but not more than one minute
from that of the net master TOD. There are 4 ways to do a LNE; manually reload
time, Hot Start, CUE & ERF, and Passive LNE. Passive LNE can only be performed
when the member radio is less then 60 seconds off net time.
5
SINCGARS FH
Characteristics & Definitions (4)
• Julian Date
The net time includes the Julian date. The Julian date is only 2 digits. There are 2
different Julian calendars, one for a regular year and one for leap year. The next
leap years are 2012, 2016, & 2020.

channels could be programmed for SINCGARS single channel frequencies.
SINCGARS should always have the Encryption Mode set to SECURE.

Frequency hopping operation requires all radios in the net to be within 4 seconds of
the Net Control time. The radio has 7 clocks, a base clock, and 1 for each of the 6
SINCGARS channels. The base clock is viewed by selecting MAN or CUE.
To manually load time, follow these steps.
1. Obtain the correct net time.
2. From the Programming menu, select Global, then Set Clock.
3. Arrow up to Day and enter the correct Julian Date.
4. Enter the hour.
5. Set the minute ahead of net time, do not press ENT yet!
6. Press ENT when the net time matches the time entered in the radio. This
starts the clock at 0 seconds.
If the radio time is more then 4 seconds but less then 60 seconds from Net time,
then Passive Late Net Entry can be used to synchronize the clock. From the main
operational screen press & hold the ALT key then press the GR key. LNE will now
be in the lower left of the screen. Do not press the PTT, this will cancel LNE. Wait
for traffic to be heard; when the radio receives traffic, the clock will synchronize to
