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.

You can search for any accessible repeaters in your
local area by using the Repeater scan. (p. 5-2, 5-3)
