ICOM Fill of RT

TM 11-5820-890-10-8

RESPONSIBILITIES

U n i t S i g n a l O f f i c e r s / N C O s a r e responsible for determining

unit-specific loadset requirements and advising the brigade or

separate battalion level Lightweight Computer Unit (LCU) operator of

those requirements.

The LCU operator, using the computer,

assembles data into loadsets and distributes them to the using units.

TF CHANGES

When changes in task organization can be anticipated, revised

loadsets are developed by the supporting LCU operator. When time

does not permit LCU operator support, using units change net IDS as

appropriate to accommodate changes in task organization.

ICOM Fill of RT

DEFINITION

An ICOM fill is the loading of a loadset plus sync time from an ANCD into

a SINCGARS RT (RT-1523A/B/C/D/E). (With RT-1523, sync time is

loaded via the RT keypad.) As a result of an ICOM fill, all six channels of

the radio are loaded with COMSEC key, FH data, and sync time. After

an ICOM fill is performed, the operator needs only to call the NCS to

enter the net.

PROCEDURE

Performing an ICOM fill is one of the basic tasks required of all

SINCGARS operators. The procedure is simple and requires only the

steps shown in Figure 4-7, below. (Also, see Primary Operator Task 2,

"Load COMSEC/FH Data/Sync Time into Radio Using ICOM Fill.")

Turn radio and ANCD ON.

(1)

On ANCD, select Radio, Send, Radio, and ICOM

(2)

from the ANCD menu.

Connect ANCD to the RT with proper fill cable.

(3)

Set RT FCTN to LD; and COMSEC to CT

(4)

Press [LOAD] button on RT

(5)

All six RT channels are now loaded with

(6)

COMSEC key, FH data, and sync time (if loading

RT-1523A/B/C/D/E).
