What must the operator select to set up the MF/HF Transceiver for a voice call?

• A. Select J3E mode for proper voice operations.
• B. Select J3E mode for SITOR operations.
• C. Select F1B mode or J2B mode depending on the manufacturer.
• D. Select F1B/J2B modes or J3E mode based on preference.

Answer: (A)

For establishing a voice call using an MF/HF Transceiver, the operator must select J3E mode. This mode is specifically designed for single sideband amplitude modulation (SSB) operations, which is ideal for voice communication. J3E provides the necessary bandwidth and signal quality needed for proper voice transmission and reception. When J3E is selected, the transceiver effectively modulates the audio frequencies for clear and understandable communication over long distances, making it the preferred choice for voice calls in MF/HF settings. Other modes, such as those designed for data transmission or lower bandwidth applications, do not cater to the specific needs of voice communications and could result in poor quality or unintelligible transmissions. The other options, while they may mention valid modes, do not focus on voice communication as effectively as J3E. So, for setting up a transceiver for a voice call specifically, J3E mode is the correct choice to ensure optimal performance and clarity in voice operations.
