Ranger RCI-5054DX 用户手册

The split frequency function offsets the transmitter frequency either 
above or below the receiver frequency by a user-programmable 
amount.  This is necessary for operating on FM repeaters.  In the 
following example, the programming of a 1 MHz offset will be 
described.  Before attempting to program the offset frequency, 
ensure that the radio is operating in the manual mode by pressing 
the MAN key. 
 
NOTE: FM repeaters may require that a sub-audible CTCSS tone be 
transmitted to gain access to the repeater. The RCI-5054DX can be 
equipped with an optional CTCSS encoder. 

 

TO PROGRAM TX OFFSET: 
1. Press the PRG (Program) key. 
2. Press the SPLIT key. The LCD display will indicate 00000 with 

PRG and SPLIT showing in the lower left-hand corner of the 
display. 

3. Using the SHF key and the UP and DOWN arrows as described 

earlier, program the display to read 10000. 

4. Press ENT.  A 1 MHz offset has now been programmed into the 

radio. 

5. Return the radio to manual operation by pressing the MAN key. 
6. Using the SHF key and the UP and DOWN arrows as described 

previously, set the radio to the desired receive frequency. 

7. Press SPLIT.  Either "SPLIT+" or "SPLIT-" will be displayed in 

the lower right corner of the display.  If "SPLIT+" is displayed, 
the transmitter will be offset 1 MHz above the receive frequency 
when keyed. If "SPLIT-" is displayed, the transmitter will be 
offset 1 MHz below the receive frequency.
