Question
What is the effect of excessive microphone gain on SSB transmissions?
Answer Options
- A) Frequency instability
- B) Distortion of the audio
- C) Excessive background noise
- D) All these choices are correct
Correct Answer: B
Explanation
In any voice transmission, setting the microphone gain (volume) too high is a common cause of poor signal quality. In a Single Sideband (SSB) transmission, excessive microphone gain causes the audio signal to clip and square off before it can be transmitted.
This clipping introduces a phenomenon called splatter, which is the generation of unwanted energy (distortion) that spills over into adjacent frequencies, causing interference to others. The operator being spoken to will hear very clipped, harsh, and often unintelligible speech; thus, the correct answer is Distortion of the audio.
