Which of the following could be the reason you are unable to access a repeater whose output you can hear?

• A. You are out of range
• B. All these choices are correct
• C. You are using the wrong frequency
• D. Your radio is malfunctioning

Answer: (B)

The correct response indicates that there are several factors that could contribute to the inability to access a repeater, despite being able to hear its output.

When you can hear a repeater but cannot access it, one reason you might be unable to transmit back to it is if you are out of range. Repeaters have specific coverage areas, and if you are outside that area, your signal may not reach the repeater, even if you can receive its signal.

Another possibility is using the wrong frequency. Repeaters typically operate on a specific input frequency for receiving signals and a different output frequency for transmitting. If your radio is set to the wrong frequency, your transmission won't reach the repeater, resulting in a failure to access it.

Additionally, equipment malfunctions can hinder your ability to transmit. If your radio has a problem, such as an issue with the transmitter, your signal may not be sent out effectively.

Thus, the single selection that encompasses all potential issues—being out of range, using the wrong frequency, and potential malfunctions of your radio—is the choice that accurately reflects the multiple reasons one might not be able to access a repeater despite being able to hear it.
