3.
Preparation of SINCGARS NON-ICOM for FH net member operation.
a. Perform before PMCS.
Refer to Figure 3 and perform before operation
PMCS on your equipment.
b. Ensure your equipment is set for SC operation; FCTN - LD MODE - SC,
CHAN - MAN, to load a single channel frequency.
c. Load the MAN frequency.
Refer to your SOI to find the MAN
frequency.
Load the frequency into the RT using single channel loading
procedures.
d. Load the COMSEC TEK. Using the KYK-13 load the TEK into the KY-57.
Loading procedures are the same as we used in SC operation.
e. Load the TSK into the RT.
The TRANSEC (TSK) is necessary to
establish a hopping pattern.
It must be loaded into the RT in order to
operate frequency hopping.
To load the FH data we will use the SINCGARS
fill device, MX-10579. Its controls and functions are the same as the KYK-
13, it does however have more fill capacity, (2 TSKs and 15 fill positions
for hopsets).
(1) Connect the MX-10579 to the RT AUDIO FILL connector using the
fill cable. If a fill cable is not available it can be connected directly.
(2) Set the MX-10579 SELECT switch to the position which contains the
TSK you are to load, (T1 or T2), and the FUNCTION switch to ON.
(3) Set the RT FCTN switch to LD-V, it must be in this position to
load the TRANSEC and will load only the TRANSEC in this position. Set the
MODE switch to FH, the only time the TRANSEC is loaded is for use in FH
operation.
(4) Press the keyboard H.Ld/O button.
The TRANSEC will be entered
into permanent memory automatically, you do not have to take any other
action. As it is being loaded the display will cycle through "LOAd", "Sto
t" and "Cold" if your CHAN switch is at MAN. If the CHAN switch is in any
other position the display will show Fill and the channel number instead of
"Cold".
(5) Set the RT FCTN switch to LD so that you can receive the ERF when
the NCS sends it. You can receive transmissions with the FCTN switch in the
LD position.
(6) Turn the MX-10579 function switch to OFF and disconnect the fill
cable from the RT and the MX-10579.
