■ Split frequency operation Split frequency operation allows you to transmit and receive on two different frequencies. Split frequency operation is performed using frequencies in VFO A and VFO B. • T he Split frequency operation is automatically turned OFF when turning ON the One-touch repeater function. The following is an example of setting 21.290 MHz for receiving and 21.310 MHz for transmitting. q Set 21.290 MHz in VFO A. w Push [SPLIT] to turn ON the Split operation. • The transmit (VFO B) frequency and "SPLIT" appear. e H old down [A/B] for 1 second to equalize the trans- mit (VFO B) frequency to the receive (VFO A) frequency. • The equalized transmit (VFO B) frequency appears. • The Quick Split function is much more convenient for selecting the transmit frequency. See the next section for details. r W hile holding down [XFC], rotate [MAIN DIAL] to set the transmit frequency to 21.310 MHz. • T he transmit frequency is displayed while holding down [XFC]. t N ow you can receive on 21.290 MHz and transmit on 21.310 MHz. To change the transmit and receive frequencies, push [A/B] to exchange VFO A and VFO B. ✔ CONVENIENT • Direct frequency shift input The frequency shift can be entered directly. q Push [F-INP ENT]. w E nter the desired frequency shift with the digit keys. • -9.999 to +9.999 MHz can be set. (in 1 kHz steps) • W hen you require a minus shift direction, first push [GENE • ]. e P ush [SPLIT] to input the frequency shift to the transmit frequency, and the Split function is turned ON. [Example] To transmit on a 1 kHz higher frequency: - Push [F-INP ENT], [1.8 1] then [SPLIT]. To transmit on 3 kHz lower frequency: - Push [F-INP ENT], [GENE • ], [7 3] then [SPLIT]. • Split Lock function Accidentally releasing [XFC] while rotating [MAIN DIAL] changes the receive frequency. To prevent this, use both the Split Lock and Dial Lock functions to change the transmit frequency only. The Split Lock function cancels the Dial Lock function while holding down [XFC] during split frequency operation. The Split Lock function is OFF by default, but can be turned ON in the Set mode.
