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:

GMRS-50X1

VISIT BAOFENGTECH.COM AND MIKLOR.COM FOR DOWNLOADS AND HELP

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.

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.

VISIT BAOFENGTECH.COM AND MIKLOR.COM FOR DOWNLOADS AND HELP

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)

NOAA Weather Channels

To add your local NOAA Weather channel a new scanning channel, start by switching your radio

to Frequency (VFO). Select your desired NOAA frequency (above) using the numerical keypad.

GMRS-50X1

VISIT BAOFENGTECH.COM AND MIKLOR.COM FOR DOWNLOADS AND HELP

Add a NOAA Channel

The following steps assume that you're in Frequency (VFO) mode and that you've entered the NOAA frequency to store to memory.

1. Press the key to enter the menu.

2. Enter “44” on the numerical keypad to get to MEM-CH.

3. Press to select.

4. Use the and keys to select an empty memory channel, or enter it directly on

the numerical keypad.

5. Press the key to confirm. a. NOTE: If the station is actively receiving it will not store. To save an active

receiving channel – remove the antenna to prevent the channel from receiving and store to memory.

6. Press the key to exit the menu.

Switch your radio to Memory (MR) to test your newly added NOAA channel.

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

VISIT BAOFENGTECH.COM AND MIKLOR.COM FOR DOWNLOADS AND HELP

your frequency according to the frequency step you've set your transceiver to (Menu Item 1: Step) 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

GMRS-50X1

VISIT BAOFENGTECH.COM AND MIKLOR.COM FOR DOWNLOADS AND HELP

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 and keys to navigate between channels (or Rotate the Selector Knob)

If you have channels programmed with Transmit power set to Low, you can use the key 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 7. - 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

• DCS

GMRS-50X1

VISIT BAOFENGTECH.COM AND MIKLOR.COM FOR DOWNLOADS AND HELP

• Tone-burst (1000Hz, 1450Hz, 1750Hz, 2100Hz)

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.

CTCSS

CTCSS is set with menus 11 R-CTCS and 13 T-CTCS.

CHAPTER 8 REPEATERS

HAPTER 9 CUSTOMIZATION

VISIT BAOFENGTECH.COM AND MIKLOR.COM FOR DOWNLOADS AND HELP

Chapter 8. - 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)

SFT-D and OFFSET only function in VFO mode.

MR mode uses and stores the RX frequency and the TX frequency directly (see Chapter 4)

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.
