You are using an FM repeater configured for 5 kHz deviation, but your transmitter is set to 2.5 kHz deviation. What is the consequence?
- A Your audio will be distorted
- B Your range will be shorter
- C The repeater will not respond
- D Your audio will be low
Correct answer: D — Your audio will be low. From the official ISED question bank, verified word for word.
