4-6. REPEATER OPERATIONS
4-6-1. T ransmitter Offsets
All amateur radio repeaters utilize a separate receiver
and transmit frequency. The receiver frequency may be
either above or below that of the transmit frequency.
The configuration of most repeaters wiil faii into one of
145.1 145.5 146.0 146.4 146.6 147.0 147.4 147.6 148.0
he categories listed be ow:
TH-26A/AT/E TH-46A/AT TH-46E
+ ■ f600 kHz -F5MHZ -F1.6 MHz
B -600 kHz -5 MHz -1.6 MHz
B
-7.6 MHz
• Offset Direction
To select the desired transmitter offset direction press
the SHIFT key. Each time you press the key the
transceiver will advance from one direction to the
other, i.e. to “ b ” (“ b ” to “ q ” with European
versions) to no offset (simplex). •
• Automatic Offset Selection (U.S.A. version)
The TH-26A / 26AT has been programmed according to
the standard ARRL (Amateur Radio Relay League) Band
Plan with regard to transmitter offset direction. Please
see
the accompanying chart for addition information
on this programming. You can, of course, override this
by using the SHIFT key if desired.

4-6-2. Reverse Function
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 B might use 146.600 for
a
transmit frequency and 146.000 for a receiver
frequency. It would be inconvenient to have to
reprogram the transceiver each time you wanted to use
these repeaters.
The REV key allows you to easily reverse the transmit
and receiver frequencies. To use the REV function press
the REV key. The R indicator will turn on in the display
to remind you that you are working a reverse pair.
To return to normal press the REV key again. The R
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.
