11 REPEATER AND DUPLEX OPERATIONS Duplex operation The duplex operation shifts the transmit frequency up or down from the receive frequency by an offset amount. DDSetting the frequency offset NOTE: The frequency offset cannot be changed when using the DR function. [MENU] > SET > DUP/TONE... > Offset Freq 1. Push [MENU]. 2. Select "DUP/TONE..." in the "SET" menu. 3. Select "Offset Freq." DDSetting the duplex direction 1. Push [QUICK]. 2. Select "DUP." 3. Select the duplex direction. •• OFF: For simplex operation (the receive and transmit frequencies are the same). •• DUP-: The transmit frequency shifts down from the receive frequency by the offset amount. •• DUP+: The transmit frequency shifts up from the receive frequency by the offset amount. 4. Rotate [DIAL] to set the offset. LLInformation •• Set to between 0.000.00 and 59.99500 MHz. •• The selected tuning step in the VFO mode is used to set the offset. •• To exit the MENU screen, push [MENU]. TIP: If the offset value causes the transmit frequency to be out of the band, "OFF BAND" is displayed when you push [PTT], and transmit will be inhibited. (p. 11-5) •• Displays "D-" or "D+." DDDuplex operation 1. Hold down [SQL] to listen to the transmit frequency to check whether another station is transmitting on it, or not. •• The shifted transmit frequency is displayed. 2. Operate in a normal way. LLIn the same way as a simplex call, alternately transmit and receive. NOTE: When the Auto Repeater function is ON, and the operating frequency is set out of the repeater output frequency range, the Duplex mode is automatically canceled.
