Q

When making VHF radio calls to nearby stations, what level of transmitting power should you use?

🔍 Key Concepts

• VHF radiotelephone power settings on small craft radios (usually 1W and 25W) • The purpose of reducing interference and keeping channels clear for safety traffic • How range and power relate: more power = longer range but more unnecessary interference nearby

💭 Think About

• If the other vessel is close by, do you need maximum range, or just enough power so they can copy you clearly? • What happens to other users on the same channel if every boat always transmits at the highest possible power? • Think about international and USCG guidance: what is the general rule about using only the power that is necessary?

✅ Before You Answer

• Check what typical guidance says about using the minimum power necessary for effective communications • Confirm which option best matches the idea of avoiding interference to distant stations • Eliminate any option that would routinely overload the channel for simple local calls
