REPEATER AND DUPLEX OPERATIONS
FM Repeater operation
A repeater receives signals and on one frequency, and
then retransmits them on a different frequency. When
using a repeater, the transmit frequency is shifted
from the receive frequency by a frequency offset.
A repeater can be accessed using the Duplex function
by setting the transceiver's offset to the same value as
the repeater's offset.
See Section 4 for details on accessing a D-STAR
repeater.

Station A
TX: 434.540 MHz
RX: 439.540 MHz
TIP:
• When the Repeater tone frequency or the
frequency offset is changed, the tone or offset for
Auto Repeater function is also changed.
• If the offset value will cause the transmit frequency
to be out of the band, "OFF BAND" is displayed on
the display when [PTT] is pushed, and transmit will
be inhibited. (p. 8-5)
