RECEIVE AND TRANSMIT
D 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
accessed using split frequency operation with the
shift frequency set to the repeaters offset frequency.
Set the offset frequency and turn ON the quick split
function in initial set mode in advance (p. 52).
If the quick split function is turned OFF, both transmit
and receive must be set separately.
Push [MODE] one or more times to select FM
mode, then set the receive frequency.
Select a suitable tone frequency or the 1750 Hz
tone burst in quick set mode.
Push [DISPLAY] for 2 sec., then push [MENU]
one or more times to select Q4 RPTR TONE.
If FM mode has not been selected, this item does
not appear.
Rotate the main dial to set a subaudible tone fre-
quency or the 1750 Hz tone burst function.
Push [DISPLAY] to exit quick set mode.
Push [(F-1)SPL] for 2 sec. (in the M1 display) to
activate the split frequency function (duplex func-
tion) with the pre-selected offset.
When a subaudible tone frequency (excepting 1750 Hz)
is selected in
, FM-T is selected simultaneously.
Push and hold [PTT] to transmit; release [PTT] to
receive.
When a 1750 Hz tone burst is selected, push and hold
[
(F-3)TON] in the M4 display while pushing [PTT] to
send the 1750 Hz tone burst.
To check the repeater input frequency (direct sig-
nal from the other station), push and hold
[(F-3)XFC] in the M1 display.
To return to simplex operation, push [(F-1)SPL].
Each memory channel can store a tone frequency
(subaudible tones or a tone burst) and an offset fre-
quency, as well as the operating frequency. Store
repeater information into memory channels for quick
and easy access to repeaters.
PROGRAMMING DUPLEX SHIFT FREQUENCY
Push [POWER] to turn power OFF.
While pushing [LOCK], push [POWER] to turn
power ON and enter initial set mode.
Select DUP 144M using [MENU] or the
[UP]/[DN] keys, then rotate the main dial to select
the desired duplex offset.
The duplex offset can be selected from 4000 kHz to
+4000 kHz.
