OPERATING THROUGH REPEATERS
Repeaters are often installed and maintained by radio
clubs, sometimes with the cooperation of local
businesses involved in the communications industry.
Compared to simplex communication, you can usually
transmit over much greater distances by using a
repeater. Repeaters are typically located on a mountain
top or other elevated location. Often they operate at
higher ERP (Effective Radiated Power) than a typical
station. This combination of elevation and high ERP
allows communications over considerable distances.

REPEATER ACCESS
Most amateur radio voice repeaters use a separate
receive and transmit frequency. You can set a separate
transmit frequency by selecting the offset frequency and
offset direction with respect to the receive frequency. In
addition, some repeaters may require the transceiver to
transmit a tone before the repeater can be used. To
transmit this required tone, activate the Tone function
and select a tone frequency.
The required offset direction, offset frequency, and tone
frequency depend on the repeater you are accessing.
Consult your local repeater reference.
