🔍 Key Concepts

• VHF maritime band frequencies and their typical use • The specific VHF channels reserved internationally for AIS (Automatic Identification System) • Difference between voice distress channels and data transmission channels

💭 Think About

• Look at which answer choices fall within the normal VHF marine band used for ship-to-ship and ship-to-shore communications. • Identify which frequencies listed are commonly associated with GPS signals or radar, and rule those out for AIS use. • Consider which frequencies are specifically allocated for digital data exchange between vessels rather than for voice distress calls.

✅ Before You Answer

• Verify which option lists two frequencies that are both within the VHF marine band around 160 MHz. • Confirm that AIS uses two dedicated VHF channels reserved internationally for data, not for voice. • Eliminate any options that are clearly used for GMDSS distress and safety calling or for GPS satellite signals, since AIS does not use those.
