How is a VHF/UHF transceiver's "reverse" function used?

• A. To listen on a repeater's input frequency
• B. To change the power output
• C. To adjust the volume
• D. To switch to a different mode

Answer: (A)

The "reverse" function on a VHF/UHF transceiver is primarily used to listen on a repeater's input frequency. In typical operation, when you use a repeater to communicate, you transmit on one frequency (the repeater's input) and listen on another (the repeater's output). The reverse function allows the operator to switch the receiver to the repeater's input frequency, enabling them to monitor communications that are being transmitted to the repeater from other users. This is particularly useful when you want to check for activity on the input channel before transmitting or if you are trying to listen to another station that is directly communicating with the repeater.

Other options, such as changing the power output, adjusting the volume, or switching modes, do not relate directly to the functionality of monitoring a repeater's input signal. These operations are controlled by separate functions on the transceiver.
