What may happen if an SSB transmitter is operated with too much speech processing?
- A It may cause insufficient modulation of the carrier
- B It may cause interference to other stations operating on a higher frequency band
- C It may cause audio distortion or splatter interference to other stations operating near its frequency
- D It may cause digital interference to computer equipment
Correct answer: C — It may cause audio distortion or splatter interference to other stations operating near its frequency. From the official ISED question bank, verified word for word.
Why
Pushing speech processing too hard clips the audio peaks, creating harsh distortion that spreads the signal's energy beyond its intended width. The full explanation — and one for every question — is in Pro.
