4. Press the key momentary to get into reverse mode, note the R icon above the frequency you entered on the
radio's A (upper) seven character display.
5. Press the key to enter the menu.
6. Enter on the numerical keypad to get to the MEM-CH menu item.
7. Press to select.
8. Use the and keys to select, for example, CH-123 or enter 123 directly on the numerical keypad.
9. Press the key to confirm.
10. Press the key to exit the menu.

Switch to Memory Channel (MR) mode with the (VFO/MR) key to test your new duplex channel. The receive frequency
will be displayed for CH-123 and when you press the transmit button the transmit frequency will be displayed for CH-123.
If you would like to name your channel you will need to do that from a computer. More on that in the section called
"Computer programming".

Chapter 13. - Repeaters

A radio repeater is an automated transceiver in a fixed location. Usually mounted high up on hilltops or on tall buildings,
but sometimes they operate within buildings for internal use. A repeater takes one signal and relays it, usually after
amplifying it by orders of magnitude. This can be very handy, as this enables you to use a small low powered hand-
held two-way transceiver such as the BAOFENG Radio to reach great distances.
Whether you're a commercial (business or government) user or an amateur radio operator, chances are you'll deal
with a repeater system sooner or later. To find out what settings to use to use your local repeater, ask your employer
or someone at your local amateur radio organization for details.

A common type of repeater is the duplex repeater. In a duplex repeater system, the repeater transmits and receives
simultaneously, but on different frequencies. To utilize this type of repeater, your radio has to be capable of transmitting
and receiving on different frequencies on the same memory channel. How you use this kind of repeater is by setting
the receive frequency of your radio to the output frequency of the repeater, and the transmit frequency of your radio
to the input frequency of the repeater. Often times, the transmit frequency to use isn't explicitly stated, but rather an
offset relative your receive frequency is specified. This is conveniently enough also how the BAOFENG Radio natively
handles repeater set up in VFO, by specifying offset rather than transmit frequency.
This is might cause confusion because many expect this to be true globally when it isn't.
Menu item number 25 SFT-D and 26 OFFSET only function in Variable Frequency Oscillator (VFO) mode.
Memory Channel (MR) mode uses and stores the RX frequency and the TX frequency separately in the same memory channel
only and does not save the SFT-D or OFFSET setting. SFT-D and OFFSET don't have to be set when using Memory Channel
(MR) mode or they can even be set completely wrong and a working repeater channel can be created.
It is convenient to use SFT-D and OFFSET with 'reverse' mode to determine the TX frequency to be stored in a channel, but
they are otherwise unused for Memory Channel (MR) mode.
The following instructions assume that you know what transmit and receive frequencies your repeater employs, and
that you're authorized or licensed to use it.
Repeater setup
1. Set the radio to Frequency Variable Frequency Oscillator (VFO) mode with the
2. Enter the repeater's output (your receiving) frequency by either using the
