REPEATER-
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.
n 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
n 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.
n 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 time you press [TONE], the selection changes as
follows:
Tone ( ) –> CTCSS ( ) –> DCS ( ) –> 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 507 ~ 512} 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.
