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

selected.
Select 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)].
Press [A/B (A=B)] to select the other VFO.
Select an operating frequency.
This frequency will be used for reception.
Press [SPLIT].

Each time you press [A/B (A=B)], the reception  
and transmission frequencies are swapped.
To quit split-frequency operation, press [SPLIT]

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.
Configure split-frequency operation as explained in 
the previous section.
Press 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.
Release [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:
X
TF-SET is disabled while transmitting.
X
You can change the transmission frequency even when the 
Frequency lock function is ON.
X
An RIT offset frequency is not added; however, an XIT offset 
frequency is added to the transmit frequency during TF-SET.
