This makes the FT-450 especially useful for high-level DX-pedition use, as the Split operationcapability is very advanced and easy to use.1. Press the [A/B] button to switch the VFO registerto VFO-A, then set the transmit frequency.2. Press the [A/B] button again to switch the VFOregister to VFO-B, then set the receive frequency.3. Now press the [STEP/SPLIT] button to activateSplit-Frequency Operation.4. The “ ” icon will appear in the display.5. To quit Split-Frequency Operation, press the[STEP/SPLIT] button again.ADVICE: It is possible to set different operating modes (forexample, LSB and USB) on the two VFOs usedduring Split operation. It is possible to set different amateur bands (forexample, 14 MHz and 21 MHz) on the two VFOsused during Split operation, if you use the multiband antenna.QUICK SPLIT OPERATIONThe Quick Split feature allows you to set a one-touch offset of +5 kHz to be applied to your radio’stransmit frequency compared to the receiving frequency. Furthermore, the transmit mode sets to thesame mode as the receiving frequency register.1. Press and hold in the [STEP/SPLIT] buttonfor one second to engage the Quick Split fea-ture. The transmit mode is set to the samemode as the receiver frequency register andapplies a frequency 5 kHz above the receiv-ing frequency register to the transmit fre-quency register.The “ ” icon will appear in the display.2. Press and hold in the [STEP/SPLIT] buttonfor two seconds to increment the transmit fre-quency +5 kHz.3. To quit the Quick Split Operation, press the[STEP/SPLIT] button again.[STEP/SPLIT] button[A/B] button[VOICE/C.S] button[STEP/SPLIT] buttonADVICE:If you assign the “TXW” feature into the [VOICE/C.S] button, you may also listen to the TX frequencytemporarily while pressing the [VOICE/C.S] button during Split operation.
