  • Page 24: Antenna Basics

    VISIT BAOFENGTECH.COM AND MIKLOR.COM FOR DOWNLOADS AND HELP 17 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.

  • Page 25: Antenna Requirements

    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) UV-25X2 / UV-25X4 / UV-50X2...

  • Page 28: Making A Call

    VISIT BAOFENGTECH.COM AND MIKLOR.COM FOR DOWNLOADS AND HELP 21 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)

  • Page 29: Channel (Mr) Mode

    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.

    VISIT BAOFENGTECH.COM AND MIKLOR.COM FOR DOWNLOADS AND HELP 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 • DCS • Tone-burst (1000Hz, 1450Hz, 1750Hz, 2100Hz) UV-25X2 / UV-25X4 / UV-50X2...

    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) UV-25X2 / UV-25X4 / UV-50X2...
