31ENHANCED COMMUNICATIONSSPLIT-FREQUENCY OPERATIONUsually you can communicate with other stationsusing a single frequency for receiving andtransmitting. In this case, you select only onefrequency on either VFO A or VFO B. However, thereare cases where you must select one frequency forreceiving and a different frequency for transmitting.This requires the use of two VFOs. This is referred toas “split-frequency operation”. One typical casewhich requires this type of operation is when you usean FM repeater {page 32}. Another typical case iswhen you call a rare DX station.When a rare or desirable DX station is heard, thatoperator may immediately get many simultaneousresponses. Often, such a station is lost under thenoise and confusion of many calling stations. If youfind that you are suddenly being called by manyoperators, it is your responsibility to control thesituation. You may announce that you will be “listeningup 5 (kHz, from your present transmit frequency)”, or“listening down between 5 and 10 (kHz)”.1 Press [MAIN], [A/B] to select VFO A or VFO B onthe main transceiver.• “tA” or “tB” appears to show which VFO isselected.2 Select an operating frequency.• The frequency selected at this point will beused for transmitting.• To copy the selected VFO frequency to theother VFO, press [A=B].3 Press [A/B] to select the other VFO.4 Select an operating frequency.• The frequency selected on this VFO will beused for receiving.5 Press [SPLIT].• “SPLIT” appears.• Each press of [A/B] reverses the receive andtransmit frequencies.6 To quit split-frequency operation, press [SPLIT]again.• “SPLIT” disappears.If you access Menu No. 06A and select “ON”, you canrecall a memory channel to use for either receiving ortransmitting. For more information, refer to “Memory-VFO Split Operation” {page 60} under “MEMORYFEATURES”.Note: You cannot perform SPLIT operation on the sub-receiver; ithas only one VFO.TF-SET (TRANSMIT FREQUENCY SET)TF-SET allows you to temporarily switch your transmitfrequency and receive frequency. Canceling thisfunction immediately restores the original transmit andreceive frequencies. By activating TF-SET, you canlisten on your transmit frequency, and change it whilelistening. This allows you to check whether or not thenewly selected transmit frequency is free ofinterference.1 Configure split-frequency operation as explainedin the previous section.2 Press and hold [TF-SET].3 While holding down [TF-SET], change theoperating frequency by turning the Tuning controlor by pressing Mic [UP]/ [DWN].• The transceiver receives on the frequency thatyou select, but the frequency shown on thesub-display stays unchanged.4 Release [TF-SET].• You are now receiving again on your originalreceive frequency.Successfully contacting a DX station in a pileup oftendepends on making a well-timed call on a clearfrequency. That is, it is important to select a relativelyclear transmit frequency and to transmit at the exactinstant when the DX station is listening but themajority of the groups aren’t transmitting. Switchyour receive and transmit frequencies by using TF-SET and listen. You will soon learn the rhythm of theDX station and the pileup. The more proficient youbecome at using this function, the more DX stationsyou will contact.Note:uIf you press [FUNC], [ATT/ F LOCK] to lock the operatingfrequency before using TF-SET, pressing an incorrect button bymistake retains the original receive frequency.uTF-SET is disabled while transmitting.uIf you have recalled a memory channel (excluding CH 290 to299), you cannot change the recalled frequency using theTuning control.uTo enable the Tuning control, access Menu No. 06B and select“ON”. Pressing Mic [UP]/ [DWN] after recalling a memorychannel changes the memory channels.uAn RIT frequency shift is not added; however, an XIT frequencyshift is added to the transmit frequency.
