Which option correctly lists the three active UHF radio modes as set through the UFCP?

• A. Mode A, mode C, mode S
• B. Transmit, receive, monitor Guard
• C. Transmit/receive and monitor Guard, Transmit/receive, Guard
• D. Preset, manual, automatic

Answer: (C)

The UHF radio on the UFCP can operate in three active modes that cover how you handle talking, listening, and emergencies. One mode is transmit/receive and monitor Guard, meaning you can talk on the assigned channel while also listening to the guard frequency for emergency calls. The second mode is transmit/receive, which is the standard two‑way communication without special guard monitoring. The third mode is Guard, which is a receive‑only setting focused on listening to the guard frequency rather than actively transmitting.

These three modes together match how the UFCP exposes UHF radio operation: a combined mode with guard monitoring, a normal two‑way mode, and a guard‑only listening mode. The other options refer to different systems (for example, transponder modes) or groupings that don’t describe UHF radio operating modes.
