RECEIVE AND TRANSMIT
Repeater operation
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.
For accessing a repeater which requires a repeater
tone, set the repeater tone frequency in set mode
as described below.
q Set the offset frequencies (HF, 50 MHz) and turn
ON the quick split function in set mode (others) in
advance. (p. 69)
w Push [VFO/MEMO] to select VFO mode.
e Push the desired band key.
r Push [AM/FM] several times to select FM mode.
t Set the receive frequency (repeater output fre-
quency).
y Push [SPLIT] for 1 sec. to start repeater operation.
Repeater tone is turned ON automatically.
Shifted transmit frequency and TX appear in the sub
readout.
The transmit frequency can be monitored while pushing
[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.
Setting the repeater tone
Some repeaters require subaudible tones to be ac-
cessed. Subaudible tones are superimposed over
your normal signal and must be set in advance. The
transceiver has 50 tones from 67.0 Hz to 254.1 Hz.
Each memory channel can store an independent set-
ting.
q Select FM mode.
w Push [TONE] for 1 sec. to enter tone set mode.
e Push [(F-1)] to select the repeater tone item.
r Rotate the tuning dial to select the desired re-
peater tone frequency.
t Push [EXIT/SET] to exit tone set mode.
Available repeater tones (Unit: Hz)
Store repeater tone frequencies and ON/OFF settings
in memory channels for easy recall.
