3. Installation and maintenance procedures are the same for NCS operation
as for SC and FH net member.
In fact the only control that is set
differently is the MODE switch. In Lesson 1 we said that the FH/M was used
only by the NCS. This switch position allows the RT to control the other
radio sets in the net.
The only other differences are in loading and
operating functions. The TEK, TSK and hopset you load are generic to all of
the radio nets in the command (Bde).
In order to prevent interference
between the unit nets you will change the Net ID of the hopset. In order to
operate all nets within the command without interfering with each other,
each NCS will change the Net ID. This changes the point (frequency) where
the radio starts hopping causing different radios to hop on the frequency at
a different time. FH Sync Time is also necessary for FH operation. It will
be sent to the net members during Cold Start procedures.

Preparation for FH NCS operation.
a. Perform pre-mission checks.
b. Load the TEK into the KY-57 using the same procedures we used in
previous lessons. The TEK is stored in the KYK-13.
c. Load FH data into the RT using the MX-10579. As the NCS you must
load all of the FH data so you can send it to the net members during Cold
Start procedures.
(1) TRANSEC. Load the TSK using the same procedures as were used in
net member operation.
Connect and turn on the MX-10579, set the select
switch to the position containing the TSK, press the H.Ld button. The TSK
will automatically be stored in permanent memory.
Remember to load a TSK
the RT FCTN switch must be in LD-V and the MODE switch in FH.
(2) Load the MAN and CUE frequencies.
Use SC loading procedures.
You will need the MAN frequency to ERF the net members and the CUE frequency
in case someone needs to CUE you for a Cold Start later.
(3) HOPSET.
To load the hopset, set the RT FCTN switch to LD, it
will not load a hopset in LD/V. If you attempt to load with the FCTN switch
in the wrong position the display will show "Bad". Set the MX-10579 select
switch to the position containing the Hopset, and function switch to ON.
Press the H.Ld button on the RT keypad to load the hopset in holding memory.
Like the KYK-13, the MX-10579 may lose its fill if you press the initiate
button when it is connected to the RT and turned on.
The hopset is not
entered into permanent memory automatically, you must enter it from the
keypad. Press the Sto/ENT button, the display will show "Sto_". Press the
number button of the channel (1) you want the hopset stored in, the display
will show "Sto 1" and blink.
