Characteristics & Definitions
• 1000 Net IDs
• Loadset, Lockouts & ESETs
• Hot Start Net Opening
• Cold Start Net Opening
SINCGARS FH (2)
•Net IDs (000-999) are used to divide the Hopset in multiple networks by
changing the starting point in the Hopset. There are 1000 net IDs per TSK. A
SINCGARS Loadset can have one to six TSKs.
• Lockout set is a set of frequencies that are not allowed in the Hopset. For
example civilian TV stations that exist in the SINCGARS operational range.
• An ESET (Electronic Set) contains SINCGARS FH data, a TSK, and a net ID.
• A SINCGARS Loadset contains up to five TEKs, one KEK, six ESETs, and up to
8 Lockout sets. A Loadset is loaded into the radio in one step using an AN/CYZ-
10 or a AN/PYQ-10 (SKL). Sometimes this is referred to as an ICOM Fill,
(Integrated COMSEC Fill).
• Hot Start Net Opening is a method of entering a SINCGARS FH Net by loading
a radio with the FH Loadset and accurate time.
• Cold Start Net Opening is a method of opening a SINCGARS FH net where
member stations load the FH Loadset then the Master station transmits the Net
ID and net time to each member radio.
