Which statement correctly describes the SATCOM mode in UHF operations?

• A. SATCOM operates only on HF frequencies.
• B. SATCOM does not encrypt.
• C. SATCOM is one of four UHF modes and requires the radio to be secured before use.
• D. SATCOM is a DAMA mode.

Answer: (C)

In UHF operations, SATCOM is the satellite-based communication mode, and it is one of the four standard UHF operating modes. Because satellite links carry sensitive information and travel through an environment where interception or compromise is more likely, the radio must be secured before use—crypto must be active and keys loaded—before you can transmit or receive over SATCOM. This security requirement is what makes SATCOM distinct from other UHF modes. The statement isn’t about HF operation, it reflects that encryption is used, and it recognizes that DAMA is a separate access method associated with SATCOM rather than the SATCOM mode itself.
