Antenna Basics
Your Mobile Radio Kit does not include an Antenna. It is VERY Important to NOT transmit without a
antenna or dummy load attached to the mobile radio. Doing so, will cause harm to the internal
components of your radio.
You will want to choose a suitable antenna for the bands you plan on transmitting and receiving on.
If you plan on transmitting on 145MHz you will want to ensure you have picked an antenna that
states it is capable of working with 145MHz. If an antenna is not properly tuned for the frequency
you transmit on – it can cause damage with the reflected power going back into the radio.
Pick an antenna with SWR of less than 1.5:1 to safely transmit.
Grounding Plane:
Antennas require an appropriate grounding plane to properly work:
Magnetically Mounted Antennas:
These antennas must be grounded to a metal surface, such as a vehicle body. Magnetic base
antennas do not properly operate unless they are fully magnetically grounded first.
18
VISIT BAOFENGTECH.COM AND MIKLOR.COM FOR DOWNLOADS AND HELP
NMO or PL-259 Base Antennas:
These antennas will normally require a base or mobile hardware kit. These kits are grounded either
through: drill or clamp inserts on vehicles, magnetically mounted, or available as stationary base
hardware kits. Some antennas may include a base station grounding plane kit.
Antenna Requirements
Antenna SWR Rating: 1.5:1 or less (on the radio frequencies in use.)
Antenna Impedance: 50 ohm (use 50 ohm rated coax and coax connectors)
Antenna Grounding: Ensure the antenna is mounted with a grounding plane
Visually Inspect Coax/Connectors for any Slits or Damage – moisture should not be allowed to
penetrate fittings or your coax
To maximize the life of your radio, it is important to understand antenna basics before transmitting
on your radio, transmitting without an antenna, or with high SWR (Standing Wave Ration) – can
void warranty support.
An Active SWR Meter is a great tool to have when selecting an antenna for your needs. You can
monitor and confirm that your SWR is within safe levels when setting up your radio for the first
time (periodically checking SWR and your antenna set-up is advised)

Pound # Key
Keypad Lock
To enable or disable the keypad lock, press and hold the
key for about two seconds.
A quick toggle of the # will alternate power levels from High power to Low power
The keypad lock will lock both the main radio buttons itself and also the handheld keypad.
The PTT/MONI/and Power Buttons will not be locked when enabled.
Star * Key
A short momentary press of the key enables the reverse function (reverses the TX/RX settings
according to Offset settings)
When listening to broadcast FM a momentary press will start the scanning. Scanning in broadcast
FM will stop as soon as an active station is found
To enable scanning, press and hold the
key for about two seconds

Turning the unit on
To turn the unit on, simply push and hold the volume knob until it turns on. If your radio powers on
correctly there should be an audible tone after about one second and the display will show a
message or flash the LCD depending on settings
Turning the unit off
To turn the unit off, simply push and hold the volume knob until it turns off. The unit is now off.
Adjusting the volume
To turn up the volume, turn the volume knob clock-wise.
To turn the volume down, turn the volume/power knob counter-clock-wise.
By using the monitor function (MONI button), you can more easily adjust your volume by
adjusting it to the un-squelched static.

Making a call
Press and hold the PTT button on the side of the handheld mic to transmit. While transmitting,
speak approximately 3-5cm (1-2 inches) from the microphone. When you release the PTT your
transceiver will go back to its receive mode.
Channel selection
There are two modes of operation: Frequency (VFO) mode, and Channel or Memory (MR) mode.
For everyday use, Channel (MR) mode is going to be a whole lot more practical than Frequency (VFO)
mode. However, Frequency (VFO) mode is very handy for experimentation out in the field.
Frequency (VFO) mode is also used for programming channels into memory. For details on how to
program your transceiver see Chapter 4, Programming.
Ultimately which mode you end up using will depend entirely on your use case.
Frequency (VFO) mode
In Frequency (VFO) mode you can navigate up and down the band by using the
and
keys
(or rotating the selector knob). Each press (or rotation click) will increment or decrement your
frequency according to the frequency step you've set your transceiver to (Menu Item 1: Step)
22
VISIT BAOFENGTECH.COM AND MIKLOR.COM FOR DOWNLOADS AND HELP
You can also input frequencies directly on your numeric keypad with kilohertz accuracy. However,
the radio will floor to the nearest frequency that corresponds to your frequency step, in other
words, when you input frequencies with greater than 1kHz resolution (such as 145.6875 MHz in the
example below), always round your input up.
Just because you can program in a channel does not mean you're automatically authorized
to use that frequency.
Transmitting on frequencies you're not authorized to operate on is illegal, and in most
jurisdictions a serious offence. If you get caught transmitting without a license you can and
will get fined, and in worst case sent to jail.
However, it is legal in most jurisdictions to listen. Contact your local regulatory body for
further information on what laws, rules and regulations apply to your area.
Channel (MR) mode
The use of Channel (MR) mode is dependent on actually having programmed in some channels to
use. To find out more on how to program channels see Chapter 4, Programming.

Once you have channels programmed and ready, you can use the
between channels (or Rotate the Selector Knob)
and
keys to navigate
If you have channels programmed with Transmit power set to Low, you can use the
to momentarily switch over to high power if you're having trouble getting through.

Monitor Both VFO & MR Modes
You can toggle from VFO and MR (Memory Recall) mode by either pressing the V/M button on the
front of your radio, or you can toggle modes from the Handheld Mic by a long press of the ‘Menu’
button.
The VFO/MR mode will only toggle on the current selected A/B/C/D line – while the other channel
lines will remain on channel or memory mode as they were selected.
This allows you to monitor channel and frequency mode simultaneously

Chapter 6. - Selective calling
Some times when you're working with larger groups of people using the same channel, things can
get very crowded, very fast. To minimize this problem, several methods of blocking out unwanted
transmissions on your frequency have developed. In general, there are two forms of selective calling
in two-way radio systems: Group calling, and individual calling.
Group calling, as the name suggest, is a one-to-many form of communication. Every radio in your
working group is configured the same way and any radio will make contact with every other radio in
the group.
Individual calling, some times also known as paging, is a one-to-one form of communication. Every
radio is programmed with a unique ID code. And only by sending out a matching code can you get
that radio to open up to your transmissions.
The BTECH X-SERIES MOBILES features three additional ways of group calling
(2TONE, 5TONE, AND DTMF CALLING ARE FOUND IN CHAPTER 5):

CTCSS

Using these features does NOT mean that others won't be able to listen in on your
transmissions.
They only provide a method to filter out unwanted incoming transmissions. Any
communications made while using these features will still be heard by anyone not
employing filtering options of their own.
You can change the CTCSS or DCS settings while in memory (MR) mode.
CTCSS and 1750Hz tone-burst are also popular methods among amateur radio operators to open up
repeaters.

Chapter 7. - 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.
Whether you're a commercial (business or government) user or an amateur radio operator, chances
are you'll be dealing 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 by specifying
offset rather than transmit frequency. (Example 145.000MHz Receive with .600MHz transmit is a
transmit Channel of 145.600MHz)

The following instructions assume that you know what transmit and receive frequencies your
repeater employs, and that you're authorized to use it.
1. Set the radio to Frequency (VFO) mode with the
key.
2. Enter the repeater’s output (your receiving) frequency by either using the
and
keys, or by entering it directly on the numerical keypad.
3. Press the
key to enter the menu.
4. Enter Menu 47 to get to frequency offset.
5. Press
key to select.
6. Use the
and
keys and the numerical keypad to enter the specified frequency offset.
See the section called “26 OFFSET - Frequency shift amount” for details.
7. Press
to confirm and save.
8. Enter Menu 46 on the numeric keypad to get to offset direction.
9. Use the
and
keys to select +(positive) or -(negative) offset.
10. Press
to confirm and save.

11. Optional:
a. Save to memory, see Chapter 4 for details.
b. Set up CTCSS; see the section called “CTCSS” for details.
12. Press
to exit the menu.
If everything went well, you should be able to make a test call through the repeater. If you're
experiencing problems making a connection to the repeater, check your settings and/or go
through the procedure again.
If you're still unable to make a connection, contact the person in charge of the radio system
with your employer or your local amateur radio club, as the case may be.
If you for some reason want to listen to the repeater's input frequency instead, press
momentarily and you'll reverse your transmit and receive frequencies.
This is indicated in the LCD on the radio with an R in the top row, next to the + and - for the
offset direction.

Chapter 8. - Application Specific Setup
Commercial Radio Setup
PLMR users in the United States are mandated to move to 12.5 kHz narrowband communication in
the 150-174 MHz VHF and 421-512MHz UHF bands by January 1, 2013.
Follow these instructions to set your radio to Narrowband mode:
This section is only true for VFO mode.
WN is settable on a per channel basis and has to be set prior to storing a channel.
Once a channel has been programmed, the channel must be deleted and reprogrammed to
change the WN setting.

To find out what other channels and features needed, please contact your employer.
Amateur Radio Setup
In contrast with Commercial radio operators, who often need very specific requirements to be
compatible with a very specific radio implementation, Amateur radio operators tend to need the
broadest possible settings in order to be compatible with as many systems as possible. This
basically implies turning all the fancy features that you typically might need for a commercial setup
off.
In a typical Amateur radio setup the following settings would be recommended:
•
•
•
•
Set bandwidth to Wide (menu item 7).
Turn Receive DCS and CTCSS off (menu items 10 through 11).
Turn off Squelch Tail Elimination (STE) features (menu items 53 through 54).
Turn roger beep (ROGER) off (menu item 25).

You may be tempted to use FRS, GMRS, MURS (in the USA) or PMR446 (in Europe)
frequencies. Do note however that there are restrictions on these bands that make this
