Some repeaters utilize a “Reverse Pair”, i.e. the transmit

/ receive frequencies are exactly the reverse of another

repeater. For example repeater A uses 146.000 for a

transmit frequency (INPUT) and 146.600 for a receiver

frequency (OUTPUT). Repeater В might use 146.600 for

a transmit frequency and 146.000 for a receiver fre

quency. It would be inconvenient to have to reprogram

the transceiver each time you wanted to use these re

peaters.

The REV/STEP key allows you to easily reverse the trans

mit and receive frequencies. To use the REV function

press the REV/STEP key. The REV indicator will turn on in

the display to remind you that you are working a re

verse pair.

To return to normal press the REV/STEP key again. The

REV indicator will turn off.

This function is also useful to check the input frequency

of the repeater so that you can determine if you are

within range for simplex communications.

5-6-3 Tone Operation

Some repeaters require the use of a control signal to ac

tivate the repeater. Several different methods are cur

rently in use.

In the United States sub-audible tones are sometimes

used. 38 different Sub-audible frequencies are possible.

In Europe a 1750 Hz tone is used in transmit. Press and

hold the Microphone 1750 key to transmit with the ac

cess tone; you need not press the PTT key.

Since this tone is required in Europe and the United

Kingdom a 1750 Hz tone encoder is included with

models delivered to these countries.

1. Press the F key for longer than 1 second. The F indi

cator will begin to flash. Press the TONE/T.ALT key

within 10 seconds of pressing the F key. The current

tone frequency will show in the display.

Press the key for longer than

1 second.

2. Rotate the tuning
