Successfully contacting a DX station in a pileup

FM REPEATER OPERATION
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

Note:
◆
When programming 2 separate frequencies using 2 VFOs,
be sure to select FM mode on both VFOs.
◆
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.
