When you keep the radio set
tuned to output maximum power,
it causes which of the
following problems?
1.
Increases RFI/EMI on
transmitting unit only
2.
Increases receive data
errors on receiving units by
saturating the data terminal
sets only
3.
Increases RFI/EMI on the
transmitting unit and
increases receive data
errors by DTS saturation
4. Decreases RFI/EMI on the
receiving units

When the NCS enters dummy PUs,
which of the following net
conditions will exist, if any?
1. Net efficiency increases
2. Net cycle time decreases
3. Net cycle time increases
4. None, dummy PUs have no
effect on the net
4-12.
What following NCS action is
the most effective net
management technique when a PU
is having trouble maintaining
Link-11 communications?
1.
2.
3.
4.
Continuing normal Link-11
operations the trouble PU
Directing the PU to go to
radio silence so that the PU
does not respond to
interrogations
Directing all units to
change from a HF frequency
to an UHF frequency
Removing the troubled PU
from the polling sequence
until the problem is
corrected and the
troubled
PU is ready to reenter the
net
