LATE NET ENTRY

4.6.

4.6a.

General

The term "Late Net Entry" means that the operator missed the

DEFINITION

announced net opening time and wishes to enter the net now, the

operator left the net for some reason and now wants to re-enter, or

sync time in the operator's radio now differs by more than

+/- 4 seconds from that of the net.

There are fours ways in which an operator can perform a late net entry,

METHODS

each described below:

(1)

Passive method of late net entry;

(2)

The Hot Start option;

(3)

Reloading sync time option; and,

(4)

The CUE and ERF method.

All four methods are effective. The one to use is the one which best fits

PREFERENCE

your situation.

Passive Method

4.6b.

When your situation will permit use of the Passive method, it is the

EASIEST

easiest to use, requires minimum action on the part of the operator.

The SINCGARS radio has a built-in capability to bring itself back into

BUILT-IN CAPABILITY

the +/-4 second window.

The typical situation where the Passive method is most useful is when

SITUATION

the radio remains fully loaded with data but sync time has, for whatever

reason drifted out of the +/-4 second window. It must still be within

one minute of net sync time.

An indicator of the above situation is that no traffic is heard on the net for

PROCEDURE

some period. The operator merely presses [FREQ] on the keypad, and

then [SYNC]. The RT display shows "LF XXX". The operator then waits

for traffic to be heard on the net, at which time the display drops the "L''

and reads a normal "F XXX." At this point, time has been electronically

brought back into sync, and the operator is back in the net. (See

Primary Operator Task 4 for details.)
