How many modes of operation does the PRC-160 support, and what are they?

• A. Five modes: FIX, HOP, ALE, 3G, LPD
• B. Four modes: FIX, HOP, ALE, 3G
• C. Five modes: FIX, HOP, ALE, 3G, HOP2
• D. Six modes: FIX, HOP, ALE, 3G, LPD, DPL

Answer: (A)

The question tests which operation modes are officially supported by the PRC-160. The radio has five modes: FIX for a fixed frequency, HOP for frequency-hopping operation, ALE for Automatic Link Establishment, 3G for higher-rate data, and LPD for Low Probability of Detection. DPL, Digital Private Line, is a privacy feature that can be used with other modes but is not listed as a separate mode of operation, which is why it isn’t counted among the five. Also, there isn’t a separate HOP2 mode; the standard hopping mode is simply HOP.
