REPEATER OPERATION
Repeater operation
Repeaters extend the operational range of the
transceiver by retransmitting the signals it receives.
Repeaters 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. In Simplex operation,
transceivers transmit and receive on the same
frequency. In Duplex operation (using a repeater)
transceivers transmit and receive on different
frequencies. It automatically does this when one of the
repeater channels is selected.
