FM REPEATER USE
E Operation
A repeater amplifies received signals and transmits
them at a different frequency. When using a re-
peater, the transmit frequency is shifted from the
receive frequency by the offset frequency as below.
It is convenient to program repeater information into
a memory channel. (p. 34)
@) Select the desired band as the main band with
the [M/S] switch.
®© Push [FM] to select FM mode.
@) Set the receive frequency (repeater output fre-
quency).
@ Push [FUNC] then [FM-DUP] to select — duplex
or push them again for + duplex.
- "DUP —" or "DUP +" appears to indicate the transmit
frequency for minus shift or plus shift, respectively.
- The U.S.A. and Australia versions have an auto
repeater function. (next page)
E Tone information
SUBAUDIBLE TONE
(U.S.A. and Australia versions only)
@ Push [TONE] to turn the subaudible tone encod-
er ON.
@) Set the tone frequency if desired.
- Push [SPCH*SET] for 2 sec.
- Push [TONE].
Set mode is
selected.
Tone encoder
frequency appears.
- Rotate the tuning dial to select the desired tone
frequency.
- Push [SPCH] to exit set mode.
WE Offset frequency
- For the U.S.A. and Australia versions, one-touch
repeater is available. Push [FM] to set the pre-
programmed duplex direction and to turn the sub-
audible tone encoder ON. See the next page.
© Push and hold [PTT] to transmit.
- The displayed frequency automatically changes to
the transmit frequency (repeater input frequency).
- When the repeater requires a tone, see the section
below.
- Push and hold [CHECK] to check whether the other
station's transmit signal can be directly received or
not.
© Release [PTT] to receive.
@ To return to simplex, push [FUNC] then
[FM*DUP] once or twice to clear the "DUP" indi-
cator.
- For the U.S.A. and Australia versions, push [FM]
once or twice to cancel the "DUP" and "T" settings.
(3) Push [TONE] to turn the subaudible tone encod-
er OFF.
e Subaudible tone frequency list
(Unit: Hz)
DTMF TONES (HM-14 is required.)
Push the desired digit keys on the microphone in
sequence to transmit DTMF tones.
1750 Hz TONE (Europe and Sweden versions only)
Push [TONE] for 1-3 sec. to transmit a 1750 Hz tone
call signal.
Frequencies can be independently set for each
band. Set the desired offset frequency as follows:
Appears when 1 kHz or 1 MHz tuning step is selected.
The display shows a
0.6 MHz (600 kHz)
offset frequency.
ΠSelect the desired band as the main band with
the [M/S] switch.
(2) Push [FUNC] then [FM-DUP] to select duplex.
@) Push [SPCH*SET] for 2 sec. to enter set mode.
@ Push [FM] once or twice to select the offset
frequency setting display.
©) Rotate the tuning dial to select the desired fre-
quency.
- Selectable step increment is the same as the preset
tuning step in FM mode. (p. 18)
- 1 KHz tuning step is selected in SSB/CW mode.
- Use [KHz/MHzZ] for quick frequency setting.
© Push [SPCH] to exit set mode.
