Alinco DR-435T - Channel Step Selection; Repeater (Duplex) Operation

5. Basic Operation
Changing the channel step
1.
Be sure the unit is in VFO mode. Refer to page
21 to enter into the SET mode. CT
Select the channel step parameter setting using Display for channel step
the tuning knob. The current channel step will
be displayed as below.
STP-5 STP-83 STP-10 STP-125 STP-15
(5 kHz) (8.33 kHz) (10 kHz) (12.6 kH2) (15 kHz)
STP-50 STP-30 STP-25 STP-20
(50 kHz) (30 kHz) (25 kHz) (20 kHz)
Press PTT or any one of the keys except SQL
on the front panel to enter the desired step into
the transceiver’s memory. The display will then
return to the original status.
Please note that settings below 10 kHz may be automatically
corrected according to the selected step.
REPEATER (DUPLEX) Operation
Shift Direction and Offset frequency setting
Conventional repeaters are operated in the DUPLEX mode. =
It receives an incoming signal (UP-LINK) on one frequency ‘” 5 rALA
and re-transmits on another (DOWN-LINK). The difference mou
between these two frequencies is called the offset frequency. at-600 kHz
If the UP-LINK frequency is higher than the DOWN-LINK
frequency, the direction is positive, and if it is lower, the shift
direction is negative. The offset is variable between 0 to 99.995
MHz on this unit.
Press the F key. While the F icon stays on the display, press a —0.600 ———~ +0.600 af
MHz key. The display shows the current status of shift direc-
tion and offset frequency. The default value is 0.60 MHz (600 Shift release
kHz) in the negative direction. Press MHz key until the de-
sired offset direction is set. If SIMPLEX mode (without chang-
ing transmit and receive frequency) is desired, select the po-
sition where both - and + icons disappeared.
1.
Z.
Rotate the dial or use UP/DOWN keys on the microphone to change the shift fre-
quency. It changes in accordance with the channel step setting.
In this mode, if the F key is pressed again, the offset frequency can be changed in
1 MHz steps for faster setting.
Press PTT or any key except F or MHz on the front panel to return to the original
status.
