Usually you can communicate with other stations using a single frequency for receiving and transmitting. In this case, you select only one frequency on either VFO A or VFO B. However, there are cases where you must select one frequency for receiving and a different frequency for transmitting. This requires the use of 2 VFOs. This is referred to as “split-frequency operation”. One typical case which requires this type of operation is when you use an FM repeater {page 25}. Another typical case is when you call a rare DX station.

When a rare or desirable DX station is heard, that operator may immediately get many simultaneous responses. Often, such a station is lost under the noise and confusion of many calling stations. If you find that you are suddenly being called by many operators, it

is your responsibility to control the situation. You may announce that you will be “listening up 5 (kHz, from your present transmission frequency)”, or “listening down between 5 and 10 (kHz)”.

1Press [A/B (A=B)] to select VFO A or VFO B.

•“ ” or “” appears to show which VFO is selected.

2Select an operating frequency.

•This frequency will be used for transmission.

•To copy the selected VFO frequency to the other VFO, press and hold [A/B (A=B)].

3Press [A/B (A=B)] to select the other VFO.

4Select an operating frequency.

• This frequency will be used for reception.

5Press [SPLIT].

•“ ” appears.

•Each time you press [A/B (A=B)], the reception and transmission frequencies are swapped.

6To quit split-frequency operation, press [SPLIT] again.

• “ ” disappears.

TF-SET allows you to temporarily switch your transmission frequency and reception frequency. Canceling this function immediately restores the original transmission and reception frequencies.

By activating TF-SET, you can listen on your transmit frequency, and change it while listening. This allows you to check whether or not the newly selected transmission frequency is free of interference.

1Configure split-frequency operation as explained in the previous section.

2Press and hold [TF-SET], then turn the Tuning control or press Mic [UP]/ [DWN] to change the transmission frequency.

•The transceiver receives on the frequency as you change, but the frequency shown on the sub-display (the original reception frequency) stays unchanged.

3Release [TF-SET].

•You are now receiving again on your original reception frequency.

Successfully contacting a DX station in a pileup often depends on making a well-timed call on a clear frequency. That is, it is important to select a relatively clear transmission frequency and to transmit at the exact instant when the DX station is listening but the majority of the groups aren’t transmitting. Switch your reception and transmission frequencies by using the TF-SET function and listen to your transmission frequency. You will soon learn the rhythm of the DX station and the pileup. The more proficient you become at using this function, the more DX stations you will contact.

Note:

XTF-SET is disabled while transmitting.

XYou can change the transmission frequency even when the Frequency lock function is ON.

XAn RIT offset frequency is not added; however, an XIT offset frequency is added to the transmit frequency during TF-SET.
