*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 properly set the Automatic Level Control (ALC) on a single sideband (SSB) transceiver, you typically adjust the **transmit audio or microphone gain**. Here's why:

1. **Correct Answer: Transmit audio or microphone gain**
   - The ALC is designed to prevent overdriving the transmitter, which can cause distortion and splatter. By adjusting the microphone gain, you control the audio input level to the transmitter. The ALC circuit monitors this level and ensures it stays within a range that prevents distortion while maintaining good audio quality.

2. **Why the other choices are incorrect:**
   - **RF clipping level**: This is not typically adjusted for ALC settings. RF clipping is more related to signal processing and not directly involved in setting ALC.
   - **Antenna inductance or capacitance**: These are related to antenna tuning and matching, not to the audio input level or ALC settings.
   - **Attenuator level**: An attenuator reduces signal strength but is not used for adjusting ALC. It might be used to prevent overloading a receiver, but it doesn't control the audio input level to the transmitter.

3. **Useful Rule of Thumb:**
   - When setting the microphone gain, speak into the microphone at a normal level and adjust the gain so that the ALC meter on the transceiver just begins to show activity. This ensures that the audio level is optimal for transmission without causing distortion.
