Most Amateur radio voice repeaters use a separate
reception and transmission frequency. The
transmission frequency may be higher or lower than
the reception frequency. In addition, some repeaters
may require the transceiver to transmit a subtone
before the repeater can be used.

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.

HF/ 6 m band repeaters usually operate in the
29 MHz FM sub-band and 51-54 MHz band. This
special service combines the advantages of FM
operation, good fidelity with noise and interference
immunity, with the excitement of HF DX (long
distance) communications. Even on a quiet day,
10 m FM provides reliable around-town
communications with the potential for sudden DX from
across the country or around the world.

When operating through a repeater, over deviation caused
by speaking too loudly into the microphone can cause your
signal to “talk-off” (break up) through the repeater.

In general, FM repeaters require the transceiver to
transmit a sub-audible tone to prevent other repeaters
on the same frequency from locking each other up.
The required tone frequency differs among repeaters.
Repeaters also differ in their requirements for either
continuous or burst tones. For the appropriate
selections for your accessible repeaters, consult your
local repeater reference.

After completing the tone settings, pressing and
holding Mic [PTT] causes the transceiver to transmit
the selected tone. If you have selected a 1750 Hz
tone, the transceiver sends a 500 ms tone burst each
time transmission starts.
