Which method can be used to enter a transceiver's operating frequency?

• A. The keypad or VFO knob
• B. The microphone or antenna
• C. The speaker or power switch
• D. The display or selector switch

Answer: (A)

The correct method for entering a transceiver's operating frequency involves using the keypad or VFO (Variable Frequency Oscillator) knob. The keypad allows operators to type in a specific frequency directly, which is a quick and efficient means for setting the desired operating frequency. Meanwhile, the VFO knob enables users to tune to frequencies by turning the knob, adjusting the frequency smoothly across a range. Other methods such as using the microphone or antenna do not allow for frequency entry. The microphone is used primarily for transmitting voice and does not interact with frequency settings directly. The speaker and power switch serve different functions; the speaker outputs audio signals while the power switch turns the transceiver on or off. Lastly, the display typically shows the current frequency settings or other information but doesn't allow for frequency entry, and the selector switch may be used to change modes or channels but is not directly involved in setting a specific frequency. Therefore, the keypad or VFO knob is the appropriate choice for entering an operating frequency on a transceiver.
