What MF frequency is designated for DSC on the Coast Guard guard beyond the primary?

• A. 2187.5 kHz
• B. 2182 kHz
• C. 156.525 MHz
• D. 156.8 MHz

Answer: (A)

DSC on the MF band uses a dedicated digital calling frequency. That frequency is 2187.5 kHz (2.1875 MHz). It is the standard MF frequency for DSC transmissions, used for distress alerts, safety calls, and routine DSC traffic, and it is separate from the MF voice distress channel. The 2182 kHz frequency is for MF voice distress and calling, not DSC. The other two options are on the VHF band: 156.525 MHz is the VHF DSC calling frequency (Channel 70), and 156.8 MHz is Channel 16, used for voice distress and calling.
