606FUNCTIONS FOR TRANSMIT Quick split functionWhen you push the [SPLIT] switch for 1 sec., split fre-quency operation is turned ON, the undisplayed VFOis automatically changed according to the plus/minusshift frequency programmed in set mode (p. 83) orequalized when 0 kHz (default value) is programmedas the split shift frequency. Quick split operation isturned ON by default but can be turned OFF in setmode (p. 83).q Suppose you are operating at 21.290 MHz (USB) inVFO A.w Push [SPLIT] for 1 sec.• Split frequency operation is turned ON.• The VFO and VFO B are equalized.e While pushing [XFC], rotate the tuning dial to setthe frequency offset between transmit and receive.• When [XFC] is released, the receive frequency is indi-cated.DD Split offset frequency settingBy setting an often-used split frequency offset in ad-vance, you can use the quick split function to select splitoperation at the push of one switch.Set the split offset frequency in advance in set mode(p. 83, item 12). The example at right shows the splitoffset is set to +0.020 MHz.➥ Push [SPLIT] for 1 sec. to activate the quick splitfunction.• The transmit frequency is offset from the receive fre-quency according to the offset in set mode.DD Split lock functionThe split lock function is convenient for changing onlythe transmit frequency. When the split lock function isnot used, accidentally releasing [XFC] while rotating thetuning dial, changes the receive frequency. The splitlock function is ON by default, but can be turned OFFin set mode.q While split frequency operation is ON, push[LOCK/SPCH] to activate the split lock function.w While pushing [XFC], rotate the tuning dial tochange the transmit frequency.• If you accidentally release [XFC] while rotating the tuningdial, the receive frequency does NOT change.Shows shift frequency and directionA G C D U P C M P T B W S C P+ 2 O .
