🔍 Key Concepts

• VHF-FM marine weather channels used by the U.S. Coast Guard and NOAA Weather Radio • The purpose of Channel 16 (156.80 MHz) versus dedicated weather broadcast channels • Difference between VHF-FM (MHz) marine band and MF (kHz) distress/safety frequencies

💭 Think About

• Which frequencies listed look like standard VHF marine working or calling channels, and which look like continuous weather broadcast channels? • What is the primary use of 156.80 MHz, and would you normally listen there for routine, continuous local weather forecasts? • Look at the units (kHz vs MHz): which ones match typical NOAA/USCG weather broadcast frequencies around the U.S. coast?

✅ Before You Answer

• Identify which choice is the international VHF distress, safety, and calling channel and what it is normally used for • Recognize that marine voice weather broadcasts in U.S. coastal waters are typically on VHF-FM weather channels in the 162 MHz range • Confirm that kHz values given are in a different band (MF/HF) and think about whether those are normally used for local routine weather in the Falkner Island/Long Island Sound area
