OPERATING THROUGH REPEATERS

Select a band.

Select a receive frequency.

Select an offset direction.

Select an offset frequency.

Activate the Tone function, if necessary.

Select a tone frequency, if necessary.

Press the PTT switch.

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.
