SNYC TIME SUMMARY
o All radios in an FH net must have the same time, plus or
minus 4 seconds.
o The NCS radio, operating in FH-M, pulls all net radios to the
NCS sync time.
o Use of late net entry feature (SYNC/L.E.) widens sync time
window to 1 minute.
o When an ERF is sent, sync time of sender is entered into
receiver's radio if sync times are within one hour of each other.
o A stations may receive and store ERF and sync time in other than
operational net channel without impacting net sync time.
o NCS may obtain sync time via ERF from higher NCS or by
entering it by use of the keypad.
o NCS radio should be clearedof all data and sync time before
receiving net sync the via ERF.
o Loading sync time by keypad causes sync time stored in any
channel to be changed.
o SINCGARS RTs retain sync time for at least 24 hours when set
to STBY (OFF); sync time is lost when radio is set to OFF (STW).
o Sync time is an NCS function and responsibility; operators
should never set or check sync time; NCS provides sync time to
net members ERF.
