6 FUNCTIONS FOR TRANSMIT ■ Quick split function [SPLIT] indicator Main dial SPLIT XFC When you find a DX station, an important consideration is how to set the split frequency. When you push and hold the SPLIT switch for 1 sec., split frequency operation is turned ON and the transmit frequency is equalized to the received frequency. This shortens the time needed to begin split frequency operation. The quick split function is ON by default. For your convenience, it can be turned OFF in Others set mode. (p. 12-12) In this case, the SPLIT switch does not equalize the transmit frequency to the receive frequency. q Suppose you are operating at 21.290 MHz (USB) in VFO mode. w Push and hold SPLIT for 1 sec. • Split frequency operation is turned ON. • The transmit frequency (unselected VFO's readout) is equalized to the receive frequency (selected VFO's readout). • " F-INP " indicator appears. e Enter the desired offset frequency from the keypad then push SPLIT , or set the transmit frequency with the main dial while pushing [XFC]. • " F-INP " indicator appears when F-INPENT is pushed. • Offset frequency setting with the keypad- example To transmit on 1 kHz higher frequency: - Push F-INPENT , 1.8 1 then SPLIT . To transmit on 3 kHz lower frequency: - Push F-INPENT , GENE • , 7 3 then SPLIT . D Split lock function [LOCK] indicator The split lock function is convenient for changing only the transmit frequency. When the split lock function is not used, accidentally releasing [XFC] while rotating the main dial, changes the receive frequency. The split lock function is ON by default, but can be turned OFF in set mode. (p. 12-13) q While split frequency operation is ON, push [LOCK] to activate the split lock function. w While pushing [XFC], rotate the main dial to change the transmit frequency. • If you accidentally release [XFC] while rotating the main dial, the receive frequency does NOT change.
