Question T2B03
From subelement T2 - T2B
Which of the following describes a linked repeater network?
Why is this correct?
A linked repeater network connects multiple repeaters so that when one receives a signal, ALL repeaters in the network simultaneously retransmit it. This creates wide-area coverage from a single transmission. Option B describes diversity reception (one repeater with multiple receivers), C refers to common ownership rather than linking functionality, and D incorrectly specifies APRS as the linking method when various technologies can link repeaters.
Memory tip
Think of linked repeaters like a broadcasting network - one input reaches multiple transmitters. Look for the word 'network' in both question and correct answer as a key pattern. The defining characteristic is always signal distribution: one receives, all transmit.

Linked repeater networks enable emergency communications across wide geographical areas and support mobile operators traveling long distances. They can use traditional RF links or internet-based VoIP systems like IRLP and EchoLink. These networks are particularly valuable for emergency services coordination, where a single transmission from an incident commander needs to reach responders across multiple counties or regions simultaneously.
Think about it
Why do you think linked repeater networks are especially important during natural disasters when conventional communication infrastructure might be compromised?
