RECEIVE AND TRANSMIT
A repeater amplies received signals and retransmits
them at a different frequency. When using a repeater,
the transmit frequency is shifted from the receive fre-
quency by an offset frequency. A repeater can be ac-
cessed using split frequency operation with the shift
frequency set to the repeaters offset frequency.
NOTE: For accessing a repeater which requires a
subaudible tone, set the subaudible tone frequency
in set mode. Refer to p. 57.
q Set the offset frequencies (HF, 50 MHz) and turn
ON the quick split function in set mode in advance.
w Push [VFO/MEMO] to select VFO mode.
e Push the desired band key.
r Push [FM] to select FM mode.
t Set the receive frequency (repeater output fre-
quency).
y Push [SPLIT] for 2 sec. to start repeater operation.
- Subaudible tone encoder is turned ON automatically.
- Shifted transmit frequency and
appear in the sub
readout.
- The transmit frequency can be monitored while push-
ing [XFC] or using dualwatch.
u Push and hold [PTT] to transmit; release [PTT] to
receive.
i To return to simplex, push [SPLIT] momentarily to
clear the sub display.
