Question 3

What is the UHF called?

Answer 3

ARC-164

Question 4

Is anti jamming Transmission Security or Communications Security?

Is not COMSEC because no inherent encryption

Question 5

What does SINCGARS stand for?

Answer 5

Single Channel Ground and Airborne Radio System

Question 6

What are SINCGARS and HAVEQUICK?

Answer 6

Waveforms

Not frequencies or nets

Question 7

What does SINCGARS have that HAVEQUICK doesn’t?

Answer 7

Digital data capability

SINCGARS can be used in both clear and secure mode with the KY-58s

Question 8

How does SINCGARS operate?

Answer 8

Frequency hops at 100 freqs per second AND at a pseudo-random timing pattern

Makes the signal sound similar to random noise and difficult for anyone to understand other than the intended receiver

Question 9

Are SINCGARS and HAVEQUICK TRANSEC or COMSEC?

Answer 9

Anti jam or TRANSEC

Question 10

What is HOPSET

Answer 10

Fancy way of naming a set, or table, of computer generated hopping frequencies

Question 11

Starting point for radio to begin hopping within hopset

Question 13

Is SINCGARS used for VHF or UHF?

Answer 13

VHF

Question 14

HAVE QUICK

What form does the Net Number take?

Answer 14

AXX.XYY

The YYs determine HQ I or HQ II

HQ I = 00
HQ II = 25

Indicates hop rate (00 slowest)
