*Question G2A12:
What control is typically adjusted for proper ALC setting on a single sideband transceiver?*  

*Correct Answer is  B: Transmit audio or microphone gain*  

### AI Response: (may contain errors)  

To understand the proper ALC (Automatic Level Control) setting on a single sideband (SSB) transceiver, let's analyze the options provided.

### Correct Answer: B - Transmit audio or microphone gain

- **Explanation**: The ALC system is designed to prevent distortion in the transmitted signal by automatically adjusting the audio level. The transmit audio or microphone gain control is the primary adjustment that affects the input level to the transmitter. By setting this control correctly, you ensure that the audio signal is strong enough to be transmitted without causing distortion, while still allowing the ALC to function effectively.

### Why the Other Choices are Incorrect:

- **A: RF clipping level**  
  - **Explanation**: The RF clipping level refers to the point at which the RF signal is clipped or limited to prevent distortion. While it is related to signal quality, it is not the primary control for setting ALC. ALC primarily responds to audio levels, not RF levels.

- **C: Antenna inductance or capacitance**  
  - **Explanation**: Antenna tuning parameters like inductance or capacitance are used to match the antenna to the transmitter's output impedance. They do not directly influence the ALC settings, which are concerned with audio input levels.

- **D: Attenuator level**  
  - **Explanation**: An attenuator reduces the power of the signal before it reaches the transmitter. While it can affect the overall signal strength, it is not the main control for setting ALC. The ALC is more directly influenced by the audio gain settings.

### Summary

- The ALC system is primarily adjusted using the **transmit audio or microphone gain** control to ensure optimal audio levels without distortion.
- Other controls like RF clipping, antenna tuning, and attenuator levels do not directly set the ALC and are therefore not the correct answer.

This understanding will help you effectively manage your SSB transceiver settings for clear and undistorted transmissions.
