RECEIVE AND TRANSMIT
D Repeater operation
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
accessed using split frequency operation with the
shift frequency set to the repeater’s offset frequency.
➀ 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.
➁ Push [MODE] one or more times to select FM
mode, then set the receive frequency.
➂ 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.
➃ 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
➂, “FM-T” is selected simultaneously.
➄ 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.
➅ To check the repeater input frequency (direct sig-
nal from the other station), push and hold
[(F-3)XFC] in the M1 display.
➆ 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
➀ Push [POWER] to turn power OFF.
➁ While pushing [LOCK], push [POWER] to turn
power ON and enter initial set mode.
➂ 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.
