7 SPECIALIZED COMMUNICATING
FM REPEATER OPERATION
Most Amateur radio voice repeaters use a separate
receive and transmit frequency. The transmit frequency
may be higher or lower than the receive frequency. In
addition, some repeaters may require the transceiver to
transmit a subtone before the repeater can be used.
receive and transmit frequency. The transmit frequency
may be higher or lower than the receive 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.

allows communications over considerable distances.
HF repeaters operate only in the 29 MHz FM sub-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 meter 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.
