Transmitting A 1750 Hz Tone; Reverse Function - Kenwood TH-D74A User Manual

TRANSMITTING A 1750 Hz TONE

Most repeaters in Europe require that a transceiver transmit
a 1750 Hz tone. On a TH-D74E, simply pressing [CALL] will
transmit this tone. It is also possible to program [1750Hz] on
the front panel as a [CALL] key for transmitting the 1750 Hz
tone.
1 Access Menu No. 142.
2 Set to [1750Hz].
Some repeaters in Europe must receive continuous signals
for a certain period of time, following a 1750 Hz tone. This
transceiver is also capable of remaining in the transmit mode
for 2 seconds after transmitting a 1750 Hz tone.
1 Access Menu No. 143.
2 Set to [On].
Note:
◆ While remaining in the transmit mode, the transceiver does not
continuously transmit a 1750 Hz tone.
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], [REV] to select an offset direction.
• Each time you press [F], [REV], the offset direction
changes as follows:
Simplex operation ➡ + ➡ – ➡ Simplex operation
• If you are using a TH-D74E, 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.

REVERSE FUNCTION

After setting a separate receive and transmit frequency, you
can exchange these frequencies using the Reverse function.
This allows you to manually check the strength of signals you
receive directly from other stations, while using a repeater. If
the station's signal is strong, move to a simplex frequency to
continue the contact and free up the repeater.
1 Press [REV] to turn the Reverse function [On] or [Off].
• When the Reverse function is On, the <
appear on the display.
Note:
◆ If the transmit frequency is outside the allowable transmit
frequency range when using Reverse, pressing [PTT] will
cause an error tone to sound and transmission will be inhibited.
◆ If the receive frequency is outside the receive frequency range
when using Reverse, an error tone will sound and Reverse will
not operate.
◆ The ARO (Automatic Repeater Offset) will not function when
Reverse is ON.
◆ You cannot switch Reverse On or Off while transmitting.
