🔍 Key Concepts

• Emission designations describe bandwidth, modulation, and type of information (e.g., telephony/voice) • VHF-FM marine radios use frequency modulation (FM) for voice (telephony) on VHF band • Understand emission code structure: first symbol = type of modulation, second = nature of signal, third = type of information

💭 Think About

• Which choice has the correct symbol for frequency modulation in the first position? • For normal marine VHF voice (radiotelephony), what should the third character (type of information) be? • Look at which options represent single sideband or other modes that are not standard for everyday VHF marine voice channels.

✅ Before You Answer

• Verify which letter in the first position of the emission code corresponds specifically to FM (frequency modulation) • Confirm that the third character used for voice/telephony emissions is correct for standard marine communications • Eliminate any designations that are typically used for SSB (single sideband) or non-FM services rather than standard VHF marine radio
