The net control station (NCS) is responsible for controlling the operations of a net.
Net members must understand that they have to carefully follow NCS guidance. If
they do not, it may jeopardize a mission.
NCS responsibilities include:
1. Opening and closing a net.
2. Maintaining net discipline.
3. Controlling net access.
4. Knowing who is a member of the net.
5. Imposing net controls.
INTRODUCTION. Special data are used by the RT to operate in FH mode. Items 1
thru 4 must be the same in each net RT for net stations to communicate in FH mode.
Refer to the glossary (page E-3) for definitions as needed.
1. Cold start TSK. Transmission security (TRANSEC) key (TSK) used for cold start
net openings, Operator loads TSK into channel 1. RT then automatically loads
MAN channel (also called channel 0) with TSK.
2.
Lockout set data (when needed) is loaded from an ECCM fill device or
by ERF.
