Question
How is a VHF/UHF transceiver’s “reverse” function used?
Answer Options
- A) To reduce power output
- B) To increase power output
- C) To listen on a repeater’s input frequency
- D) To listen on a repeater’s output frequency
Correct Answer: C
Explanation
The ‘reverse’ function on a VHF/UHF radio is a convenience feature used to troubleshoot or manage repeater communications. It momentarily swaps the repeater’s input and output frequencies in your radio’s memory. This allows you to quickly check if you can hear the signal of the station you are talking to on the repeater’s input frequency (the one your radio is transmitting on).
If you can hear the other station directly on the input frequency (simplex), it means you are close enough to switch to simplex mode and free up the repeater for other users. It can also be used to quickly listen for interfering signals or activity on the input frequency.
