The frequency 156.8 MHz is associated with which SOLAS channel?

• A. Channel 16
• B. Channel 70
• C. Channel 9
• D. Channel 13

Answer: (A)

VHF radio channels in SOLAS designate specific safety roles, and the one assigned to 156.8 MHz is the international distress, safety, and calling channel. This channel is monitored by all ships and coast stations so a distress call or initial hail can be heard anywhere. In an emergency, you would use this channel to call for help, and once contact is established you move to a working channel for the ongoing conversation. The other channels serve different functions: a DSC-focused channel handles digital distress and calling, while the inter-ship safety and bridge-to-bridge channels are used for safety calls and navigational coordination, not the primary distress-calling channel. So the frequency 156.8 MHz corresponds to Channel 16.
