Which of the following is NOT a direct cause of instability in a receiver?
- A Dial display accuracy
- B Mechanical rigidity
- C Feedback components
- D Temperature variations
Correct answer: A — Dial display accuracy. From the official ISED question bank, verified word for word.
Why
Dial display accuracy simply tells you the frequency you are tuned to; it does not change how the receiver circuits behave or cause the signal to waver. The full explanation — and one for every question — is in Pro.
