LESSON 1: PREPARE/OPERATE SINCGARS NON-ICOM FREQUENCY HOPPING (NET MEMBER)
TASK:
Prepare and Operate SINCGARS NON-ICOM FH (Net member).
CONDITIONS:
1. PERFORMANCE.
Given an installed SINCGARS NON-ICOM w/KY-57, MX-10579
w/TSK, KYK-13 w/TEK, extracts of unit SOI, extracts of TM 11-5820-890-10-3,
TM 11-5810-256-OP-2, and TM 11-5810-256-10, pencil, DA Form 2404 grease
pencil and a qualified SOJT monitor.
2. PERFORMANCE-ORIENTED.
Given lesson materials, paper, pencil and without
supervision.
STANDARDS:
1. PERFORMANCE.
Correctly prepare and operate a SINCGARS NON-ICOM radio
set as a net member in a secure frequency hopping net IAW performance
measures 1 through 14 within one out of two attempts and within 30 minutes.
2. PERFORMANCE-ORIENTED.
Demonstrate competency of the task skills and
knowledge by correctly responding to 75 per cent of the multiple choice
written practice exercise covering Lesson 1.
REFERENCES:
TM 11-5820-890-10-3, TM 11-5810-256-10, and TM 11-5810-256-OP-10.
1. Situation: In a tactical environment you are required to provide secure
radio communications from 1st Plt, Co A, 54th IN Bn, to the company CP. You
have been communicating successfully with your SINCGARS NON-ICOM radio set
in the SC mode.
Due to increasing interference, which seems to be
intentional, the NCS has directed the net to switch to Frequency Hopping
(FH) operation.
You must prepare your SINCGARS NON-ICOM radio set for FH
operation and operate in the net as a net member.
2. As we discussed in subcourse SS-0754, Operate SINCGARS Secure Single
Channel, VINSON communications security equipment is used to protect your FM
voice communications from interception and deception. Even though you have
this protection in the SC mode your signals are still susceptible to
interference, especially intentional interference (Jamming).
By using the
Frequency Hopping mode the effects of interference can be reduced to a level
that has little or no effect on your communications.
FH also affords
protection from the enemy's efforts to use radio direction finding to locate
your position.
