Repeater Operation - Icom IC-455 Instruction Manual

■ Repeater operation

Repeaters extend the operational range of the transceiver by retransmitting the received
signals. They are usually located on the top of a building or a mountain, as the elevation
increases their effectiveness, allowing the user to transmit and receive over greater
distances. During a standard operation or in the Simplex mode, transceivers transmit and
receive on the same frequency. When operating in the Duplex mode (example: accessing
a repeater), the transceiver will transmit and receive different frequencies. It automatically
does this when one of the repeater channels is selected.
D Accessing a repeater
A repeater amplifies received signals, and retransmits them on a different frequency,
allowing you to communicate over greater distances with improved reliability. To use a
repeater, a repeater channel must be selected (Repeater channel 1 to 8, and 41 to 48).
You can search the accessible repeater in your local area using the Repeater Scan
function. (p. 15)
1. Select a repeater channel. (p. 4)
2. Hold down [PTT] and speak into the microphone at
