DEFINITION
Approximate rating of how much energy a battery can de-
liver before its useful life is finished.
Circuit in RT in which a frequency and/or hopset can be
loaded and stored.
Method used to initially open a net.
Transmission security key (TSK), which, when combined
with proper switch settings will result in “COLD” display.
When ‘COLD” is displayed, it is possible to begin cold start
net opening.
Variable used to encrypt/decrypt signals during a secure
operation. TEK and KEK are COMSEC keys.
Used to contact a FH radio net when you are not an active
member of that net. Cue can be used if you are operating
in SC and wish to contact an FH net.
Method of operation used to reduce the effects of jam-
ming.
Method in which an RT is loaded with FH data transmitted
by an NCS (net control station) radio; used during cold
start openings and FH data updating.
Data the RT operates on during frequency hopping: in-
cludes hopsets, lockout sets, FH sync time, TSK, TEK,
and KEK.
Clock in RT used for timing FH operations. The NCS is the
timekeeper for net RT clocks.
ECCM method of operation. RT circuits automatically
change frequencies rapidly.
Memory in the RT used when sending, loading or retrieving
FILL data.
During operation, radio antennas MUST be able to be seen
by each other for good communication. The path between
the radio antennas is referred to as LOS.
Data which prevents transmission/reception on particular
frequencies; used for FH by all RT using the hopset that
needs the lockout set (may not be needed for some hop-
sets).
