Which of the following describes a linked repeater network?
The correct answer is A: A network of repeaters in which signals received by one repeater are transmitted by all the repeaters in the network. A linked repeater network is a system where multiple repeaters are connected together, so that when one repeater receives a signal, all the other repeaters in the network simultaneously retransmit that signal.
This creates a wide-area coverage system where a transmission on one repeater is heard across the entire network. Linked networks are commonly used for emergency communications, public service events, and regional coordination. The linking can be done via radio links, internet connections, or other methods. This allows operators to communicate over a much larger area than a single repeater could cover.
Exam Tip
Linked network = All repeaters retransmit. Remember: In a linked network, when one repeater receives a signal, all repeaters in the network retransmit it simultaneously.

Real-World Application
Your region has a linked repeater network with five repeaters covering different areas. When you transmit on the repeater in your city, all five repeaters simultaneously retransmit your signal. Operators listening on any of the five repeaters hear your transmission, creating coverage across the entire region instead of just one city.

Why Other Options Are Wrong
Option B: Incorrect. A single repeater with multiple receivers is not a linked network. It's just one repeater with enhanced receive capability.
Option C: Incorrect. Multiple repeaters with the same control operator are not necessarily linked. They could operate independently.
Option D: Incorrect. APRS (Automatic Packet Reporting System) is a digital messaging system, not a repeater linking method. While APRS can be used with repeaters, it doesn't define a linked repeater network.
