INTRODUCTION. Continued
2
Lockout set data* (when needed) can be loaded by an ECCM fill device or by ERF.
3
Hopset data A hopset may be loaded by ECCM fill device or by ERF.
4
FH sync time is needed to synchronize FH communicationsFH sync time is loaded by transmission from the net
controller radio during ERF or by an NCS using keyboard actions.
5
MAN frequency is a SC frequency It is loaded into the MAN channel by key- board actions
The MAN channel is
primarily used for cold starts.
6
CUE frequency is loaded into the CUE channel by keyboard actions It enables stations not in a FH net to "CUE", or
contact the FH net.
(*Note: Lockout set data are normally built in to hopsets during the computer generation process
Only rarely will an NCS
need to load or ERF a lockout set
Procedures are addressed in this chapter in case they are required on rare
occasion.)
WARNING
RF ENERGY IS PRESENT NEAR THE ANTENNA DURING TRANSMISSION. MAINTAIN AT LEAST 30 INCHES
BETWEEN VEHICULAR ANTENNA AND PERSONNEL DURING TRANSMISSIONS.
The NCS opens a FH radio net. The procedure used for opening a net is called cold start net opening. Check the
following table to determine what FH data is needed before a net opening. If net is to be opened in CT, refer to basic
COMSEC procedures.
NOTE
Only members designated by the commander need to load CUE frequency
However,
NCS
and
alternate NCS should load CUE Items 2, 3, and 4 are ERFed from NCS to members.
