REPEATER-1
REPEATER ACCESS
Most repeaters use a receive and transmit frequency pair with
a standard or non-standard offset (odd-split). In addition, some
repeaters must receive a tone from the transceiver in order
to gain access to the repeater. For details, consult your local
repeater reference.
■ Selecting an Offset Direction
The offset direction allows your transmit frequency to be
higher (+) or lower (–) than the receive frequency.
1 Select your desired band (A or B).
2 Press [F], [SHIFT] to select an offset direction.
• Each time you press [SHIFT], the offset direction changes as
follows:
Simplex operation
➡ + ➡ – ➡ Simplex operation
• If you are using an E type transceiver, when operating on the
430 MHz band, the offset direction changes as follows:
Simplex operation
➡ + ➡ – ➡ = (–7.6 MHz) ➡ Simplex
operation
If the offset transmit frequency falls outside the allowable
range, transmitting is inhibited. Use one of the following
methods to bring the transmit frequency within the band
limits:
• Move the receive frequency further inside the band.
• Change the offset direction.
Note: While using an odd-split memory channel or transmitting, you cannot
change the offset direction.
OPERATING THROUGH REPEATERS
■ Selecting an Offset Frequency
The offset frequency is the value which the transmit
frequency will be offset from the receive frequency. The
default offset frequency on the 144 MHz band is 600 kHz for
all type versions. The default on the 430/440 MHz band is 5
MHz.
1 Select your desired band (A or B).
2 Enter Menu mode and access Menu 400.
3 Set the appropriate offset frequency value.
• The selectable range is from 00.00 MHz to 29.95 MHz, in
steps of 50 kHz.
Note: After changing the offset frequency, the new offset frequency will
also be used by Automatic Repeater Offset.
■ Activating the Tone Function
To turn the Tone function on:
1 Select your desired band (A or B).
2 Press [TONE] to turn the Tone function ON.
• Each press of [TONE] changes the selection as follows:
Tone (
) ➡ CTCSS ( ) ➡ DCS ( ) ➡ Cross Tone (
: default) ➡ Off (no display).
• The
icon appears on the display when the tone
function is ON.
Note: When accessing a repeater that requires a 1750 Hz tone, you do not
need to activate the Tone function. Simply press the key assigned to the
1750 Hz tone {Menu 906 ~ 911} to transmit the tone.
Repeaters are often installed and maintained by radio clubs, sometimes with the cooperation of local businesses involved in the
communications industry.
Compared to simplex communication, you can usually transmit
over much greater distances by using a repeater. Repeaters
are typically located on mountain tops or other elevated
locations. They generally operate at higher ERP (Effective
Radiated Power) than a typical station. This combination
of elevation and high ERP allows communications over
considerable distances.
