SECTION III. NCS NET TROUBLESHOOTING
NCS TROUBLESHOOTING CHECKLIST
The NCS’s biggest responsibility is to ensure uninterrupted communications (regard-
less of operational conditions or other requirements). At times, radios will not re-
spond as they should. NCS guidance to operators should emphasize the importance
of trying the operator troubleshooting checklist before reporting a technical problem
with the radio. Likewise, NCS operators can keep communications flowing by taking
any or all of the following NCS troubleshooting steps.
Check your radio(s) using the operator checklist.
Ensure NCS station has LOS (line-of-sight) with at least one net member.
As the situation permits, move your station as required to establish LOS with
all stations.
Make sure all stations have the most recent update (FH data). Call missing
stations using old preset if appropriate.
Check distance of forward stations to ensure that they are still within the
SINCGARS voice/data range. If not, consider a RXMT mission to regain con-
tact.
Ensure that you transmit often enough to keep all member stations in time
synchronization.
Make sure that your radio is the only one in the net set to
. Especially
check alternate NCS stations to ensure that they have returned to FH after
answering a CUE call.
Be alert to CUE calls from other commanders, aircraft, and various support
elements. Ensure that you or an alternate NCS responds quickly, helps the
calling station enter the net, and minimizes interference with net operations.
If the enemy has demonstrated direction finding capabilities, make sure you
or an alternate NCS station displaces after each use of single channel commu-
nications.
Be alert to co-site interference; take immediate action if it occurs.
Respond to enemy jamming quickly: Alert the net and help members work
through jamming to continue communications.
