<p>This report presents the design of a ground station for performing satellite communications using amateur radio satellites. The resulting design integrates commercially available hardware and software to provide effective communications using all current amateur satellite analog and digital operating modes. The station is capable of growth to support message forwarding, gateway, and satellite monitoring and control functions. The acquisition plan spreads the station's acquisition over several years to keep costs within an individual's budget, and maintains flexibility to adapt to changes in satellites and communications modes available over the station's life. The station's major design drivers are sufficient link budget for reliable communications, the station's life cycle cost, ensuring radio frequency energy fields are at safe levels, placement of antennas and supports to comply with local architectural restrictions, and selection of a 435 MHz transceiver for the station.</p> <p>This project illustrates the ability of individuals or small groups to economically acquire effective satellite communications capability by integrating largely off-the-shelf hardware and software. In conjunction with small, relatively low-cost satellites, this ability places space communications and related research within reach of groups otherwise excluded from participating in satellite programs.</p> / Master of Science

<p>The radio spectrum is a resource which unlike other resources, is not consumed - it is being wasted when not being used. Effective management of this valuable resource is necessary because of the limited number of channels that are physically available for use.</p> <p> Without regulation, stations operating on the same channel in the same general area will inevitably interfere with each other and often also with others on adjacent channels. Therefore, the Federal Communications Commission (FCC) regulates the use of this national resource in accordance with rules which have been developed and continue to evolve. These rules relate to all kinds of broadcast services including AM & FM radio and TV.</p> <p> In defining the technical specifications of a new broadcast facility, the engineer must try to achieve an optimum system design while conforming to all FCC rules and regulations. The design process is divided into a number of stages which include channel and frequency selection, site selection, protection and interference studies, topographic studies, and an environmental impact statement considering the area in the vicinity of the facilities. These specifications must then be submitted to the FCC as a formal proposal.</p> <p> This report describes the design approach used in industry to specify the technical details of such a proposal and highlights the tradeoffs which are made at almost every stage of the process. The hardware needed to implement the technical details specified must be selected. Various types and configurations of transmitter-antenna systems and tower configurations are evaluated and an optimum design is sought.</p> / Master of Science

Thesis (M.A) (Media Studies)--University of Limpopo,2009. / This is a qualitative comparative study on sustainability challenges facing the community radio sector in Limpopo Province, South Africa. The study explores and determines community radio’s social acceptance to target communities, identifies its fundraising and marketing strategies, and evaluates its governance and management policies. The research draws from theories of community development and mass communication, namely: development theory and participant media theory. Detailed literature review, focus group discussion, in-depth interviews, and analyses of archival records and institutional documents were used as research methods. The case study purports that the quality of a community radio service is often a product of its resources. Furthermore, it appreciates the open access approach to broadcasting as fulfilling the original and moral imperative of community radio. However, it views sustainability issues, more specifically financial resources, as having far reaching effects on the sector’s independence and the ability to fulfill its functions. Often in community radio, the concept of sustainability tends to be narrowly used to refer to financial sustainability alone. The conclusions drawn from the comparative study of three community radio stations, namely: Botlokwa, Mohodi and Radio Turf reveal that a comprehensive approach to sustainability should recognise the role of social, organisational and financial aspects of the medium. Despite marked progress with respect to social acceptance, more innovative marketing and fundraising strategies, appropriate organisational and management policies in the sector are essential. In their absence, community radio continues to lack access to a fair share of resources and can barely raise funds to meet its obligations. Consequently, poor performance in community radio is largely attributable to sustainability challenges, particularly in rural communities where resources are often scarce as compared to urban centres. / Not listed
