A repeater amplifies 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 repeater's offset frequency.
For accessing a repeater which requires a repeater
tone, set the repeater tone frequency in tone fre-
quency set mode as described below.
q Set the offset frequencies (HF, 50 MHz) and turn
ON the quick split function in miscellaneous (others)
set mode in advance. (p. 12-15)
w Push [V/M] 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.
• [SPLIT] indicator lights and "
LCD.
• Shifted transmit frequency and "TX" appear in the sub
band.
• 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.
Some repeaters require subaudible tones to be ac-
cessed. Subaudible tones are superimposed over your
normal signal and must be set in advance. The trans-
ceiver has 50 tones from 67.0 Hz to 254.1 Hz.
q Select FM mode.
w Push [TONE] for 1 sec. to tone frequency set mode.
