Chapter 7 Offset Frequency Operation

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.
When the transmitter is keyed, the frequency display will change to
show the frequency being transmitted.
