OPERATING THROUGH REPEATERS
Repeaters, which are often installed and maintained by radio clubs, are usually located on
mountain tops or other elevated locations. They generally operate at higher ERP
(Effective Radiated Power) than a typical station. This combination of elevation and high
ERP allows communications over much greater distances than communicating without
using repeaters.
Most repeaters use a receive and transmit frequency pair with a standard or non-standard
offset (odd-split). In addition, some repeaters must receive a tone from the transceiver to
be accessed. For details, consult your local repeater reference.
OFFSET PROGRAMMING FLOW
Select a receive frequency.
Select an offset direction.
Select an offset frequency (only when programming odd-split repeater
frequencies).
Activate the Tone function (if necessary).
Select a tone frequency (if necessary).
If you store all the above data in a memory channel, you will not need to reprogram the
parameters every time. Refer to “MEMORY CHANNELS”.
Programming an Offset
You must first select an amateur radio repeater downlink frequency as described in
“Selecting an Offset Frequency”.
Selecting an Offset Direction

Reverse Function
The Reverse function exchanges a separate reception and transmission frequency. So,
while using a repeater, you can manually check the strength of a signal that you receive
directly from the other station. If the station’
s signal is strong, both stations should move to
a simplex frequency and free up the repeater.
To swap the transmission and reception frequencies:
Press【F】, 【MENU】 to switch the Reverse function ON(or OFF).
 “R”appears when the function is ON.
Note: You can turn the Reverse function ON when you are operating in Simplex Mode.
However, it does not change the Transmission/Reception frequency.
MEMORY CHANNELS
In memory channels, you can store frequencies and related data that you frequently use
so that you do not need to reprogram that data every time. You can quickly recall a
programmed channel through simple operation. A total of 199 memory channels are
available for storing frequencies, modes and other operating conditions.
SIMPLEX & REPEATER OR ODD-SPLIT MEMORY CHANNEL?
You can use each memory channel as a simplex & repeater channel or an odd-split
channel. Store only one frequency to use as a simplex & repeater channel or two separate
frequencies to use as an odd-split channel. Select either application for each channel
depending on the operations you have in mind.
Simplex & repeater channels allow:
 Simplex frequency operation
 Repeater operation with a standard offset (if an offset direction is stored)
Odd-split channels allow:
 Repeater operation with a non-standard offset
Note: Not only you can store data in memory channels, but you can also overwrite
existing data with new data.
