Q

What is the channel spacing used for VHF marine radio?

🔍 Key Concepts

• VHF marine band channeling practices for voice communications • Difference between channel spacing and bandwidth • How many distinct channels fit into the standard VHF marine frequency range (roughly 156–162 MHz) using different spacings

💭 Think About

• If you know the approximate size of the VHF marine band, which channel spacing would produce a reasonable number of channels for maritime use? • Consider common modern land-mobile and marine radio spacings: which of the options is most widely associated with traditional marine voice channels? • Think about whether marine channels are usually ‘narrowband’ like some newer land-mobile systems, or wider like older analog FM voice channels.

✅ Before You Answer

• Make sure you are thinking about marine VHF, not aviation or amateur VHF practices • Check whether international VHF marine channels (like Channel 16) are still generally regarded as the same spacing they have historically used • Confirm that the spacing you choose would allow a practical number of channels in the 156–162 MHz band, not an unrealistically high or low count
