Icom IC-R5 instruction manual Duplex operation, Setting, Rotate Dial to select DUP

■Duplex operation

USING EXPANDED SET MODE

Duplex communication uses 2 different frequencies for trans- mitting and receiving. Generally, duplex is used in communi- cation through a repeater, some utility communications, etc.

During duplex operation, the transmit station frequency is shifted from the receive station frequency by the offset fre- quency. Repeater information (offset frequency and shift di- rection) can be programmed into memory channels. (p. 16)

DSetting

qSet the receive station frequency (repeater output frequency). wPush [TS•SET] for 1 sec. to enter set mode.

eRotate [DIAL] to select “EXPAND.”

•“EXPAND” disappears after 1 sec. and “OFF” (default) and “EX” appear.

rWhile pushing [FUNC], rotate [DIAL] to select “ON.”

tRotate [DIAL] to select “OFFSET.” 4

•“OFFSET” disappears after 1 sec. and “0.000” (default) and “OW” appear.

Offset frequency item Setting indication

yWhile pushing [FUNC], rotate [DIAL] to set the desired off- set frequency within 0.000–159.995 MHz range.

• The tuning step, selected in VFO mode, is used for setting.

uRotate [DIAL] to select “DUP.”

•“DUP” disappears after 1 sec. and “OFF” (default) and “DP” ap- pear.

After 1 sec.

Duplex item Setting indication

iWhile pushing [FUNC], rotate [DIAL] to select “–DUP” or “+DUP.”

oPush [TS•SET] to exit set mode.

!0Push and hold [SQL] to monitor the transmit station fre-

quency (repeater input frequency) directly.
