Summary of Special Operator Tasks

Transfer COMSEC/FH Data/Sync Time, ANCD to ANCD

SPECIAL TASK 1:

This task is used when individual operators are required to load their

own ANCD with COMSEC keys, FH data, and sync time from one being

passed around the unit. (Many unit SOPS call for communications

specialists or designated NCOs to perform this task for operators. This

task is performed prior to net openings and during periodic ANCD data

updates.

Transfer QREF SOI Information, ANCD to ANCD

SPECIAL TASK 2:

This task is similar to Special Task 1 but differs in the procedure

followed. It is performed prior to net openings and during periodic

ANCD data updates. (Unit SOP determines whether operators,

communications specialists, or designated NCOs are responsible for

the function.)

Perform Cold Start Net Opening

SPECIAL TASK 3:

If an NCS finds it necessary to use the Cold Start method of net

opening, it is essential that operators be trained in this task. This task is

"special" in that it is unlikely the Cold Start net opening procedure will

be used frequently.

Receive Net Update ERF from NCS

SPECIAL TASK 4:

This task is performed when an NCS needs to update some element of

FH data, including sync time, using electronic transfer means. The

normal method of FH data updating is by physical connection of one

ANCD to another. ERF update provides a back-up procedure for

those occasions when electronic transfer is required by the tactical

situation of the unit.

Perform CUE and ERF Method of Late Net Entry

SPECIAL TASK 5:

This task is performed when sync time in the RT becomes, for any

reason, more than one minute different from that of the operational net.

Use of the CUE and ERF method is discouraged because it requires

single channel communication and special action on the part of the

receiving NCS. The Hot Start procedure works equally well, and it does

not involve SC mode or NCS action. (For RT-1523A/B versions, sync

time difference cannot exceed 100 days; for the RT- 1523 version,

difference cannot exceed 60 minutes.)

Conduct Retransmission (RXMT) Operations

SPECIAL TASK 6:

Performance of this task is required when one or more stations of a net

become out of normal SINCGARS operating range or an obstacle

blocks line of sight communications, This is a task that unit scouts, staff

vehicle drivers, and communications specialists should be able to

perform on short notice. The RXMT capability of the SINCGARS radio is

of significant value in various operational situations.
