Radio Training Notes
BUSH SEARCH AND RESCUE VICTORIA RADIO TRAINING NOTES BSAR members use Police and CB radios on search operations. These notes cover the skills required to effectively use those radios, including: How to use the controls on the Police and CB radios Sending and receiving radio messages The radio checks required prior to leaving the search base Use of call signs Use of pro-words such as Standby, Over, Say again, Out Use of the phonetic alphabet: e.g. Bravo Sierra Alpha Romeo Send, receive and record location information with grid references in correct format. Reference: BSAR Manual Chapter 11: Additional Skills - Communications Section, pp 82-90. RADIO SAFETY Do NOT operate any radio in an explosive atmosphere Obey “Turn Off Two-way Radio” instructions eg at petrol stations, hospitals, etc Do NOT touch the antenna when transmitting Do NOT transmit when the antenna is missing or damaged. ACKNOWLEDGEMENTS Thanks to Rik Head for preparing these notes. Use of the Victoria Police radio instruction sheet is acknowledged in developing parts of these notes.

Version: 2.7 Date: Jan 2015 Bush Search And Rescue Victoria Radio System Types There are two basic types of radio systems, conventional and trunking systems and within conventional systems there are two modes: simplex and repeater operation. Simplex – a conventional radio system Remote Base f1 (if in place) Good reception - high on hill f1 f1 Simplex Operation Search Base Poor reception One channel - uses No reception - Good reception - due to foliage the same transmit and shaded by hill close by & line of sight receive frequency Simplex channels use a single frequency (f1) for transmit and receive and allow direct communications between one radio and all other that are within range. -

Mhz As a Primary User
Response to Ofcom Consultation Q1. What future uses might this spectrum support? The availability of this spectrum is a rare opportunity. As such, the benefits should be made to the general public, as well the business stakeholders. 1. Amateur Radio:The UK Amateur Radio service is allocated the 2m band from 144.000 to 146.000 MHz as a Primary User. In comparison, the USA has an allocation from 144.000 through to 148.000 MHz. An expansion of this band by 0.5 – 1 MHz immediately above 146.000 MHz will be beneficial to the amateur radio community. 2. VHF Citizens' Band service: The UK only CB Service at 934 MHz was withdrawn in 1998, with the loss of 20 channels to GSM 900 Mobile operators. This is an opportunity to re-introduce a 20 channel CB service, at a frequency range which does not have the propagation characteristics of the 27 MHz band. An allocation at VHF will allow practical antenna lengths to be used in vehicles and buildings. In comparison, ACMA (Ofcom's counterpart in Australia) has sanctioned the use of a 77 Channel “UHF CB” service at around 476 – 477 MHz. 3. Simple UK (Business Radio): The business radio Simple UK licence permits 15 spot frequencies to be used at a 12.5 kHz bandwidth. The addition of more frequencies for this licence type will ease congestion. 4. A “personal use” radio service: There are a number of licensable and licence-free radio services available for individuals. This include PMR446 (licence-free) and the licensable Business Radio (Simple UK), as well as CB Radio on 27 MHz and a number of low-power allocations. -

Airband Radio Operator Certificate Manual
Airband Radio Operator Certificate Manual 1- Version: January 2012 About the airband radio operator license Very high frequency (VHF) airband radios are becoming more common as a tool for aircraft pilots to identify the location and intention of other aircraft in their vicinity (for VHF use at non-towered aerodromes see Civil Aviation Advisory Publication 166-1(0) and 166-2(0)).i In some classes of airspace the use of VHF airband radios is mandatory. Using a VHF airband radio requires a license endorsement. To obtain a VHF airband radio operators license you must satisfactorily (80% pass mark) complete both written and practical exams. This manual provides you with information regarding VHF airband radio use in Australia for the satisfactory completion of the written VHF airband radio operator examination. Radio communications in Australian are controlled by the Australian Communications and Media Authority ( www.acma.gov.au ). About the airband Airband radios transmit and receive a radio frequency. Radios are set to transmit and receive on specific frequencies across a band of frequencies. The radio waves that are transmitted and received are base on wavelengths and amplitudes. A cycle is one complete wave action. The frequency, measured in Hertz, is the number of cycles passing a given point in one second. One cycle per second = 1 Hertz (Hz) 1,000 Hz = 1 kilohertz (KHz) 1,000 KHz = 1 megahertz (MHz) 1,000 MHz = 1 gigahertz (GHz) The wavelength is the length of one cycle. The height of the peak or trough from the centreline is called the amplitude ; the greater the amplitude, the stronger the signal. -

University of Southern Queensland Faculty of Engineering & Surveying
University of Southern Queensland Faculty of Engineering & Surveying Telemetry and Communication Systems for Irrigation Management A dissertation submitted by Alison McCarthy in fulfilment of the requirements of ENG4111/2 Research Project towards the degree of Bachelor of Mechatronic Engineering Submitted: November, 2006 Abstract The development of wireless communication systems for agricultural and irrigation ap- plications has enabled farm managers to access real-time data from in-field sensors to improve on-farm operations. Recent research into wireless sensor networks for agri- culture has focussed on reducing the power consumption and manual configuration of the nodes by the end-user, while commercial wireless sensor networks use short-range transceivers such as Zigbee or long-range transceivers such as UHF citizen band radio. However, the research wireless sensor networks often experienced reduced reliability under field conditions. Therefore, this project aims to design a telemetry system with a focus on reliability under field conditions. UHF citizen band radio was investigated as a candidate wireless transmission medium over which audio tones, modulated with serial data, were transmitted. The modulation technique used was frequency modulation, and was implemented using integrated circuit modems. A wireless network was designed with: a polling medium access method; star topology; error handling using repetition and cyclic redundancy codes; and robust protocol. The developed telemetry system was tested under field conditions, such as in the pres- ence of crop canopy and irrigation water, and near power lines which potentially cause noise in telemetry signals. Data delivery rates of 100% were achieved using 0.5 W radios transmitting at 1200 baud for 2 km, which satisfied all the telemetry system requirements. -
