6  ENHANCED COMMUNICATIONS
SPLIT-FREQUENCY OPERATION
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 
26}
.  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)”.

SHIFTABLE RX FREQUENCY DURING SPLIT 
TRANSMISSION
When the shiftable function of the RX frequency 
in split transmission is set to ON, it is possible to 
change the RX frequency by turning the Tuning control 
during split transmission. (When it is set to OFF, the 
TX frequency changes by turning the Tuning control 
during split transmission.)

If the frequency specified by the DXer is higher 
than your current frequency, enter the specified 
frequency in the order of kHz using the numeric

specified frequency is lower, prefix a value of 
"0" to the frequency.
