![]() ![]() Therefore, names of operatives and locations involved in a particular operation should be disguised via the use of code words or call signs. Regardless of how secure the equipment you are using may be, always operate on the basis that someone could be listening in on your transmissions. First and foremost, we observe strict radio procedures to preserve the security of the information being transmitted. This is important for a number of reasons. It is important to remember that strict radio communication procedures and disciplines need to be adhered to at all times when using a radio, whether it be a hand held, vehicle based or a base station set up. In this article, we are going to look at some of the more basic, but all too often forgotten radio communication procedures required for quick, concise and accurate transmission of information via radio. In order to achieve this, a security officer has a number of tools at their disposal, such as the mobile phone, short message service, Morse code (not so common these days), and of course, radio communications. Often, we need to relay messages and information further than would otherwise be possible via verbal means. We all know that communication skills are amongst the most important skills that a security officer can possess. Assign the transmit frequency to the channel. Press the button to activate Reverse Mode and display the transmit frequency. Assign the receive frequency to the same channel in Step 6. optional - Enter the transmit CTCSS/DCS code. Skip this step when setting up the channel for the first time. optional - Delete any existing data on the channel to program. If no previous codes exist or when setting up the channel for the first time and no codes are needed, set the menu items listed below to OFF. optional - Clear any CTCSS/DCS codes previously assigned to the channel. If the incorrect band is chosen for the frequency entered in Step 6, the radio will cancel the operation. Programming data entered on the B Side (lower display) will not be saved. Like the simplex channels, the A side must be used to program the repeater channels into the radio. How to manually program a repeater channel Use the keypad to enter the frequency into the radio. It is highly advised to turn TDR off when programming directly from the radio. If the incorrect band is chosen for the frequency entered in Step 5, the radio will cancel the operation. Toggle to choose 136 MHz (VHF) or 470 MHz (UHF). The A side must be used to program channels into the radio. Press and choose the A Side (upper display). How to manually program a simplex channel Here is a great guide to how to manually program the Baofeng UV-5R, copied below.
