Icom IC-R3 Duplex Operation, Duplex shift direction, Rotate Dial until Duplex or dUP appears

Page 35

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. 14)

This function is not available in the broadcast band (0.495

– 1.620 MHz) except for U.S.A. and Canada versions.

qSet the receive station frequency (repeater output fre-

quency).

wSet the shift direction and offset of the transmit station fre- quency as described below.

ePush and hold [SQL] to monitor the transmit station fre- quency (repeater input frequency) directly.

◊Duplex shift direction

qPush [FUNC] + [(MODE) SET] momentarily to enter set mode.

• Select a non-band scope screen in advance for color LCD.

wRotate [DIAL] until “Duplex” or “dUP” appears.

•“dUP” disappears after 1 sec. and “dP” appears when color LCD is OFF.

ePush [↔] or rotate the tuning dial while pushing [FUNC] to select “–DUP” or “(+)DUP.”

•“–DUP” or “(+)DUP” indicates the transmit station frequency for minus shift or plus shift, respectively.

rPush [(MODE) SET] to exit set mode.
