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.

• 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.

SINCGARS FHCharacteristics & 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

4


• 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.

• 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.

6


• 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.

When programming SINCGARS channels, normally only 7 FH (Frequency Hopping) channels can be programmed. Six frequency-hopping channels with a TRANSEC slot assigned each and one channel for the MAN frequency. ECCM on the second programming screen must be set to FH. If SC is selected for ECCM, then all 256 channels could be programmed for SINCGARS single channel frequencies. SINCGARS should always have the Encryption Mode set to SECURE.

• Select the channel.

• Set the Encryption Mode to Secure.

• Name the channel is desired.

• Set the Operation Mode to SINCGARS. Now the Transmit Power can be set. For SINCGARs, the choices are 1, 3, & 5 watts.

Late Net Entry

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 net time.

Same as an OTAR, the JEM can receive but not transmit an ERF (Electronic Remote Fill). The ERF must be sent using an AN/PRC-119, AN/PRC-117, AN/PRC-152 or similar radio. An ERF is used to Cold Start a SINCGARS network, to send or update FH data during net operations. When notified by the NCS to prepare to receive and ERF, change the radio to the MAN channel. When the ERF is received the screen changes. Use the keypad arrows to change the storage location (1-6) and then ENT to store. Lockout sets can also be received; storage positions are 1-8.

The JEM can receive but not transmit an OTAR (Over the Air Rekey). The OTAR must be sent using an AN/PRC-119, AN/PRC-117, AN/PRC-152 or similar radio. OTAR can be received in any operation mode (e.g. Basic, ANDVT, SINCGARS, etc) The JEM must be loaded with both the old TEK & KEK and communicating with the NCS sending the OTAR. The NCS will perform an AK (automatic key) OTAR. When the OTAR is received, it automatically updates the TEK on the operational channel and updates the KEK. OTAR will be displayed in the upper right of the screen when the OTAR is received then sill display the count or OTAR receptions on the current KEK. The count is reset when a new KEK is loaded or zeroed.
