Which of the following is NOT a mode of operation on the PRC-160?

• A. 3G
• B. LPD
• C. FIX
• D. TDM

Answer: (D)

Modes of operation on the PRC-160 are distinct radio configurations you select that define how the radio handles voice and data, including the waveform, data rate, and security features. The options that are actual modes—like 3G, LPD, and FIX—are all predefined ways the radio can operate for different mission needs. Time-division multiplexing, on the other hand, is a technique for sharing a channel by dividing time into slots so multiple signals can ride on the same link. It’s a method used within some digital systems, not a stand-alone radio mode you choose on the PRC-160. Because you don’t select TDM as an operating mode on this radio, it isn’t considered a mode of operation. That’s why it’s the correct choice for “not a mode of operation.”
