frequency from 67.0 to 250.3 Hz. A repeater will only retransmit signals which contain its

particular PL tone. For example, the PL for Bozo is 127.3 Hz while that for Grissom is 94.8 Hz.

To utilize a repeater, your radio must be programmed to transmit the PL tone which the repeater

is expecting. If you don't, the repeater will ignore your signals. In some cases a repeater will

not use a PL tone, for example the Ojai repeater does not use a PL. In that case you will not

program a PL tone into the radio for that repeater.

Programming the radio to work with a repeater is similar to programming it for simplex

operation with the addition of the +/- off set and the PL tone. The programming procedures for

repeater operation follow:

Frequency Selection: If the radio is in the memory mode (there is an M showing on the left

edge of the display indicating memory mode), then push the V/M function key to place the

radio in the VFO mode. Tune the radio to the output frequency of the repeater that you

wish to use, using the same tuning procedures that were used to select a simplex frequency.

Select +/- Shift: Select the appropriate +/- off set for the repeater that you plan to use.

This is done with the SHIFT key. The word SHIFT appears above the MHz function key

which means that the FUNC key must be pushed followed by pushing the MHz key to

activate the Shift function. Performing this two keystroke operation causes a – to appear

at the top of the display indicating that the radio is now set up for a negative off set.

Performing the two keystroke operation again causes a + to appear at the top of the

display indicating a + off set. Performing the operation again causes the – and + signs to

disappear, indicating that you are back in the Simplex mode. Perform the operation as

many times as needed to achieve either a – or a + off set, as appropriate for the repeater

that you will be using.

Select PL Tone: If the repeater that you will be using requires a PL tone, then you must

select the tone which the repeater expects. Tone is selected by pushing the TS/DCS

function key. Pushing the key once will cause a T to appear at the top of the display plus a

tone frequency. Turn the Tuning Knob until the tone frequency expected by the repeater

is displayed. Complete the tone selection by pushing the V/M key to exit the selection

process. The normal display will return, except that a T is now showing on the display

indicating that a PL tone has been selected. Pushing the TS/DCS function key multiple

times will cause other functions to appear on the display. If this occurs, continue pushing

the key until only a T accompanied by a tone frequency is shown on the display and

proceed as described above.

Power Level: Set the radio's transmit power level to the lowest power needed for the repeater

to clearly receive your signal. A good level to start with is Medium. Set this power level in the

same way as was done for simplex operation.

Squelch: Set the squelch in the same manner as was done for simplex operation.

Volume Control: Finally set the Volume Control to an audio level that is comfortable.
