🔍 Key Concepts

• VHF (Very High Frequency) band limits on the radio spectrum • Typical marine VHF channel band used for ship-to-ship and ship-to-shore • Difference between HF, MF, and VHF ranges and common services that use them

💭 Think About

• Which option falls within the standard VHF band (30–300 MHz)? • Which frequencies are commonly associated with FM broadcast radio and AM broadcast radio, and can those be eliminated? • Think about what range includes familiar marine channels like Channel 16 (distress and calling).

✅ Before You Answer

• Confirm which answer choices are in MHz and which are in kHz and what that implies about the band. • Identify which choice best matches the known marine VHF channel group (around Ch. 16 ≈ 156.8 MHz). • Eliminate ranges that are too low (MF/HF) or used for broadcast radio rather than marine VHF.
