🔍 Key Concepts

• J3E is single-sideband (SSB) radiotelephony with suppressed carrier • Typical occupied bandwidth for marine SSB voice channels • Standard channel spacing used in HF marine bands for SSB

💭 Think About

• Think about how much frequency space a normal intelligible voice signal needs when transmitted as single sideband rather than AM • Recall the common HF marine SSB channel step size used internationally and how closely channels can be packed without overlapping • Compare each choice to what you know about typical SSB bandwidths (e.g., are they measured in hundreds of Hz or kilohertz?)

✅ Before You Answer

• Verify that the occupied bandwidth matches standard SSB voice practice (neither too narrow to carry clear speech nor excessively wide) • Confirm the channel spacing is consistent with ITU/IMO practices for HF marine SSB channels • Eliminate options where the bandwidth and spacing are unrealistically small (audio would sound muffled) or unrealistically large (spectrum would be wasted)
