Chapter 7 Offset (Split) Frequency Operation
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.
NOTE
When the transmitter is keyed, the frequency display will change to
show the frequency being transmitted.
