The RCI-5054DX has an offset or split-frequency feature that permits the 
radio to be operated in a half-duplex mode. This allows the user to talk on 
FM repeaters operating in the 6 meter band. (NOTE : FM repeaters may 
require that a sub-audible (CTCSS) tone be transmitted to gain access to the 
repeater. The RCI-5054DX is not factory-equipped with a CTCSS 
encoder/decoder.) The split frequency function offsets the transmitter 
frequency either above or below the receiver frequency by a user-
programmable amount. In the following example, the programming of a 100 
KHz offset will be described. Before attempting the program the offset 
frequency, ensure that the radio is operating in the manual mode by 
pressing the MAN key. 

 

1. Press the PRG (Program) key. 
2. Press the SPLIT key. The LCD display window will display "00000" with 

"PRG" and "SPLIT" being displayed in the lower left-hand corner. 

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

program the display to read "01000". 

4. Press ENT. A 100 KHz 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 for the desired receive frequency. 

7. Press SPLIT. In the lower right corner of the display, either "SPLIT+" or 

"SPLIT-" will be displayed. If "SPLIT+" is displayed, the transmitter will 
be offset 100 KHz above the receive frequency when keyed. If "SPLIT-" 
is displayed , the transmitter will be offset 100 KHz below the receive 
frequency.
