Q

Shipboard transmitters using F3E emission (FM voice) may not exceed what carrier power?

🔍 Key Concepts

• F3E emission means frequency-modulated (FM) voice transmissions • FCC and maritime radio rules place specific power limits on different emission types to reduce interference • Shipboard VHF-FM radiotelephones (used for voice) have a maximum permitted carrier power

💭 Think About

• Think about typical VHF-FM marine radios used on small and large vessels—what is their common maximum power rating? • Which of these power levels would most likely cause excessive interference to nearby coastal and ship stations if widely allowed for FM voice? • Compare these choices to what you remember about standard "high power" versus "low power" settings on marine VHF sets.

✅ Before You Answer

• Connect F3E = FM voice specifically with marine VHF radiotelephone rules, not MF/HF or other services • Recall the typical maximum power found on standard marine VHF radios sold for ship use • Eliminate any options that seem unrealistically high for normal shipboard FM voice use, considering interference and safety
