You will be checking for various signal quality
characteristics, including dc distortion, audio
distribution levels, frequency accuracy of RF signals,
spectrum analysis and loop current. Those
measurements are broad categories and can be broken
down to specific tests for specific systems.
You will correct all discrepancies, complete the
appropriate reports, and send them to the proper
authority or file them for further reference.
RADAY is the start of a new 24-hour period. At that
time all designated systems will restart. It can be a
crypto restart, the simple methods of starting (opening)
a new log, or message numbering system, starting at the
RADAY starts at 0001Z worldwide. The 0000Z
time frame does not exist and WILL NOT be used. The
following restart items is a rudimentary list to give the
user an idea of areas and items that require restart at the
beginning of the new radio day.
Protocols are generally set by the CINCs, area
commander, Naval instructions, and local instructions.
Protocols are also determined by the mission and the
area of operations.
The use of communications circuits require that
those circuits at various times of the day be placed
online, in reserve, or taken offline. The reasons have to
do with whether the circuit is needed immediately, or
can be placed on ready reserve for use, or if the
requirement for that particular circuit has expired.
Activating communications circuit usually means
turning on or starting a circuit to allow for
communications signals to ride (or pass) on them.
When a circuit is activated, it will be logged in an active
status on the status board. A circuit can be activated for
any number of reasons, including special
communications, overload, or installation of a new
To terminate or deactivate a circuit is to stop using
that path and remove all your equipment from that
particular path. The deactivated circuit is then logged
out on the status board.
By placing communications circuits standby, you
are placing them in hold. They are ready for activation
or deactivation should the need arise. Again, this type
of circuit is placed on the status board so that the
supervisor knows the status of each of the circuits under
Shifting frequencies or changing frequencies is
accomplished to allow for stronger propagation of the
circuits. When the signal strength begins to decay, the
operator will shift frequencies to another or stronger
frequencies in accordance with naval and local

CRYPTOGRAPHIC KEYING MATERIAL
Some of the new cryptosystems will use a 128-bit
electronic key that is called over-the-air-rekey (OTAR)
or over-the-air transfer (OTAT). Using this system
reduces the amount of physical keying material held on
board a command.
The key can be extracted using a KYK-13 or KYX-
15/KYX-15A. The key is then loaded into another

CAPACITY AND RELIABILITY
When trying to analyze a networks capacity and
reliability, you must first establish the criteria or level at
which you wish the system to work. Does the network
have set boundaries, or can it be expanded to include
updated or new parameters? Many avenues can be
