To set up the MF/HF transceiver for a voice call to a coast station, the operator must:

• A. Select J3E mode for proper voice operation
• B. Select J2B mode
• C. Select A3E mode
• D. Select F3E mode

Answer: (A)

Voice calls on MF/HF to coast stations are carried using single-sideband with carrier, which makes long-distance voice transmission efficient and clear. J3E is the standard SSB voice emission for these bands, so setting the transceiver to this mode ensures compatibility with coast stations and optimal use of power and spectrum. Using AM with a full carrier (A3E) wastes bandwidth and is less efficient for long-range HF voice. FM (F3E) isn’t used for HF long-distance voice to coast stations, as it behaves differently and isn’t the conventional choice for marine voice on these frequencies. The remaining option is a mode intended for other purposes, not for standard voice communication, so it wouldn’t provide proper voice transmission to a coast station. In short, J3E is the correct setting because it is the appropriate voice-mode on MF/HF for communicating with coast stations.
