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], [MHz] to select an offset direction.

• Each time you press [F], [MHz], the offset direction

changes as follows:

Simplex operation

➡ + ➡ – ➡ Simplex operation

• If you are using a TH-D72E, 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 160.

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 time you press [TONE], the selection changes

as follows:

Tone (

) ➡ CTCSS ( ) ➡ DCS ( ) ➡ Cross

Tone (

: default) ➡ Off (no display).

<Additionally, when APRS is ON and Voice Alert is

configured, Voice Alert ON is added to the above

cycle.>

• The “

” icon appears on the display when the tone

function is On.

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.
