Repeater Operation; Accessing Repeater - Icom IC-440N Instruction Manual

■

Repeater operation

Repeaters extend the operational range of the transceiver by
re-transmitting received signals. They are usually located on
the top of hills or mountains, as the elevation increases their
effectiveness, allowing the user to transmit and receive over
greater distances. During standard operation, or simplex,
transceivers transmit and receive on the same frequency.
When operating in the Duplex mode (i.e. accessing a re-
peater), the transceiver will transmit and receive on different
frequencies. It will automatically do this when one of the re-
peater channels is selected.

Accessing Repeater

A repeater amplifi es received signals and re-transmits them
on a different frequency, allowing you to communicate over
greater distances with improved reliability. When using a re-
peater, the repeater output channel (
RPT-41 to RPT-48 ) must be selected.
