Q

What are the correct VHF Channels and Frequencies for Calling/Distress, DSC and bridge-to-bridge operations?

🔍 Key Concepts

• VHF Channel 16 (156.800 MHz) use and purpose • Digital Selective Calling (DSC) and which channel/frequency it uses on VHF • Which channel is designated for bridge-to-bridge (ship maneuvering) in U.S. waters

💭 Think About

• First, identify which channel is internationally recognized for distress, safety, and calling on VHF and match it to the correct frequency in the choices. • Next, recall which VHF channel is assigned exclusively to DSC for distress alerts and safety calling, and find its frequency in the options. • Then, think about which low-power VHF channel is normally reserved for bridge-to-bridge communications between vessels and confirm its frequency.

✅ Before You Answer

• Match Channel numbers to their standard ITU VHF frequencies (e.g., what is 156.800 MHz? 156.525 MHz? 156.650 MHz?). • Confirm which channel is not used for voice, but only for DSC digital distress/calling. • Verify which channel is specifically designated as bridge-to-bridge (maneuvering and passing) in inland/coastal waters, and ensure its frequency matches 156.650 MHz in the options.
