Which two voice frequencies correspond to MF and VHF DSC broadcasts?

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

Answer: (A)

DSC uses dedicated digital calling frequencies on each band. For MF, the DSC calling frequency is 2187.5 kHz; for VHF, the DSC calling frequency is 156.525 MHz (Channel 70). These are the frequencies used when sending DSC calls, separate from the voice distress frequencies. The MF voice distress frequency is 2182 kHz, and VHF Channel 16 is 156.8 MHz for voice calls. So the two frequencies that correspond to MF and VHF DSC broadcasts are 2187.5 kHz and 156.525 MHz.
