4 RECEIVE AND TRANSMIT ■ Quick split function 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., the split frequency operation is turned ON, and the sub readout frequency and operating mode is equalized to the main readout, then enters standby for transmit frequency input. 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. 129) In this case, the [SPLIT] switch does not equalize the main and sub readout frequencies. q S uppose 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. • [SPLIT] indicator lights. • The sub readout frequency and operating mode is equalized to the main readout. • The sub readout enters standby for transmit frequency input and " " appears. • During FM mode operation, the sub readout frequency shifts from the main readout frequency according to the others set mode setting. (p. 129) • The tone encoder function is turned ON in FM mode. e R otate the main dial to set the transmit frequency; or, input the transmit frequency using the keypad and [F-INP ENT]; or, input a shift frequency using the keypad and [SPLIT]. • " " disappears when [F-INP ENT] is pushed. • Offset frequency setting with the keypad and [SPLIT]. [Example] To transmit on 1 kHz higher frequency: - Push [1.8 1] then [SPLIT]. To transmit on 3 kHz lower frequency: - Push [GENE •], [7 3] then [SPLIT]. D Split lock function 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 OFF by default, but can be turned ON in others set mode. (p. 129) q W hile split frequency operation is ON, push and hold [SPEECH/LOCK] for 1 sec. to activate the split lock function. • [LOCK] indicator lights. w W hile pushing and holding [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. 89 [SPLIT] indicator SPLIT Keypad Main dial [LOCK] indicator Main dial XFC SPEECH LOCK
