CUE and ERF Method

CUE and ERF Method

NOT SO EASY

The CUE and ERF method of late net entry does work, but it requires

much more of the operator than the other methods, described. It also

requires action on the part of the NCS or alternate NCS, and it involves

the use of SC transmissions with probable displacements following

each.

SITUATION

A situation in which an operator may find it necessary to use the CUE

and ERF method is when no net traffic is heard, data or sync time are

believed to be at fault, and neither an ANCD nor a PLGR is available for

reloading.

PROCEDURE

For the procedure to perform CUE and ERF method of late net entry,

see Figures 4-12 and 4-13, below, or Special Operator Task 5,

"Perform CUE and ERF Late Net Entry."

Load CUE and MAN frequencies into RT

(1)

Set CHAN to CUE, COMSEC to PT.

(2)

Press PTT for 5 seconds (no need to talk).

(3)

Set COMSEC to CT immediately.

(4)

Wait for NCS to respond (repeat steps (2)-(4)

(5)

every 15 seconds until a response is received.

Figure 4-12. OPERATOR'S CUE & ERF PROCEDURE

To respond to the operator's CUE and ERF request, the NCS or alternate NCS, follows the

procedure shown in Figure 4.13 (also see Primary NCS Task 5, "`Respond to CUE Calls":

Note "CUE" message in RT display.

(1)

Switch from operational channel to CUE.

(2)

Respond on CUE channel in CT mode.

(3)

Direct caller to MAN channel.

(4)

Upon caller's request, send ERF on MAN channel.

(5)

Return to operational channel, and check

(6)

communications.

Immediately displace to new location if enemy is

(7)

believed to have direction finding capabilities. (Alt

NCS normally responds to CUE calls to preclude

NCS displacement.)
