What are the two operating modes of SINCGARS FH & SC?

• A. Time Division and Frequency Stepping
• B. Frequency Hopping and Single Channel
• C. Single Channel and Fading
• D. Digital Hop and Analog Hop

Answer: (B)

The two operating modes are Frequency Hopping and Single Channel. In Frequency Hopping mode, the radio rapidly switches the carrier across a predefined set of frequencies in a pseudo-random sequence. This makes it hard for an opposing force to jam or intercept the communication because the signal does not stay on one frequency the whole time. In Single Channel mode, the radio uses a single fixed frequency for the entire transmission, which is simpler and requires less coordination but is more vulnerable to jam or interception on that specific channel. SINCGARS is designed to switch between these modes to suit the mission and environment.
