How-To and Setup Guides
Repeaters
A radio repeater is usually an automated transceiver in a specific fixed location.
Mounted high up on hills, mountains, or tall buildings, repeaters take one signal and
relay it, usually after amplifying it greatly. This enables usage of a small low-powered
handheld two-way transceiver such as the Baofeng BF-F9V2+ to transmit to greater
distances.
A radio repeater is an automated transceiver (device that can transmit and receive)
in a fixed location. Usually mounted high up on hill tops 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 the use of a small low powered handheld two-way transceiver
such as the Baofeng BF-F9V2+ to reach great distances.
A common type of repeater is the duplex repeater. A duplex repeater transmits and
receives simultaneously, but on different frequencies. To utilize this specific type of
repeater, the radio has to be capable of transmitting and receiving on different
frequencies on the same memory channel. This kind of repeater is used by setting
the receive frequency of the radio to the output frequency of the repeater, and the
transmit frequency of the radio to the input frequency of the repeater. The transmit
frequency may not always be explicitly stated, as many radios use a specific offset
relative to the receive frequency. The Baofeng BF-F9V2+ handles repeater setup in
this fashion, by specifying frequency offset rather than transmit frequency.
The following instructions assume knowledge of transmit and receive frequencies
that your specified repeater employs, as well as authorization to use it.

Programming
Computer Programming
This section assumes that the Baofeng software is installed on your PC.
Attaching the Programming Cable
Ensure that the radio is off before attaching the cable. To attach the cable, uncover
the accessory port behind the rubber flap on the right side of the radio body, align
the connectors and push in firmly. Attach the USB connector to the computer and
start the programming software, then turn on the radio.
Baofeng Software
Note: When first opening up the Baofeng programming software, the language may
default to Chinese. To change the language to English, go to the second rightmost
menu. This will open a list of available languages to select, including English.
When starting the Baofeng programming software, the Channel Information window
will show. This is where channel information for memory channels can be entered.
If the Channel Information window doesn't appear automatically, it can be shown
by going to Edit -> Channel Information.
Before adding channels, go to Communication to select the port the cable is attached
to. Next go to Program -> Read from Radio and click Read to read in any existing
channel information on the radio. This is an effective way to test the connection of
the programming cable. If the read is successful the LED on the radio will start flashing
red indicating that the radio is transmitting data to the computer.
