The main target of this work is to project and make a simple repeater working in 446 MHz tape called PMR. This repeater is made from functional station PMR and repeating program unit, which was constructed by the help of the system for recording and replaying sound. The repeater is managed by microcontroller Atmel from line AVR. The repeater records minimal and maximal temperature during its operation and its date and time is still actual thanks to transceiver DCF. It is possible to connect the transceiver with a computer by the serial link.

Dissertation / This study investigates the role of radio in South African education, with Phalaphala FM as a case study. The aim was to investigate the extent to which Phalaphala FM's programmes include educational material and the extent to which the respondents listen to Phalaphala FM to satisfy their educational needs. Phalaphala FM as a regional radio station predominantly serves rural listeners, as they often do not have access to alternative forms of media. The theoretical point of departure is the uses and gratifications with its emphasis on the active audience concept. Content analysis of Phalaphala FM' s programme schedule was conducted to determine the amount of educational material. Focus group interviews and survey research were used to determine the respondents' media usage patterns. The results indicate that entertainment programmes are given more time on Phalaphala FM and that the respondents prefer entertainment programmes, to informational and educational programmes. / Educational Studies / M.A. (Communication)

Community radio and participation - the case ofSiyaya FM illustrates that radio is a powerful tool when it comes to communication and empowerment for active listeners. However, it also shows that community members are not empowered to the same extent if they are not engaged. Participation is essential for development and empowerment as described by, among others, Chambers (1983). At the same time the thesis demonstrates that it is difficult to involve all parts of a community because of power structures and therefore the radio station might end up empowering people already in power. Siyaya FM has, however, a role to play in Cato Manor with its high unemployment rate by training people the tool of radio and also educating listeners and informing them of important issues that can improve their knowledge. In addition, the radio station can take part in building social cohesion among the different groups of community members. By strengthening community radio stations the national authorities have a potential to meet the goals of their development strategies, while at the same time fulfilling the constitutional promise of freedom of speech for all by creating access to the airwaves for everybody. However, funding shortages create obstacles for many South African community radio stations to fulfil their task as community developers. / Thesis (M.A.)-University of KwaZulu-Natal, Durban, 2006

在國內，非營利公營電台成立之初，多因特殊任務需求及對象而創設，再加上兼具公營與廣播媒體雙重特性，因此在經營與管理各方面，都與一般商業廣播電台及非營利組織有所不同。然而，對於目前國內的非營利公營電台而言，如何善用非營利組織有使命有理想的正面形象，以及廣播媒體的傳播優勢，使聽眾能認同非營利公營電台的走向，這必須藉著有效的行銷策略才能達成，而經由活動行銷的模式，也是一個比較能立即檢視成效的作法。 但公營電台也有其限制，例如沒有廣告收益只能靠政府預算、礙於相關規定無法接受企業贊助等…。因此，一個以政府提供預算為主的非營利公營電台，其行銷策略該如何擬定，才能發揮最大效益，不致浪費納稅人的付出與國家資源，實在值得我們進一步的討論與驗證。 而警廣(Police Radio Station簡稱PRS)在目前公營電台中，不論其頻道數、收聽範圍與收聽率各方面，都有較積極的表現與作為。因此本研究即藉由警廣的「關懷交通系列活動」，來檢測其行銷成效，以作為其它非營利公營電台的參考。 本研究透過問卷調查與深度訪談發現，對聽眾來說警廣是一個報導路況的「交通專業電台」這個概念一直維持得蠻正面；但在具體方面，警廣缺乏一個更容易辨識且印象深刻鮮明的logo，他可以是一個圖騰或是一個吉祥物的具體形象，代表警廣的過去、現在、未來，也可為警廣打造更深入人心的印象。 / In Taiwan, non-profit, government-owned radio stations are created for special purposes and with a specific target audience. Due to a dual-property nature of this establishment, government-owned and broadcast media, the operation and management of these stations are different from commercial ones or other non-profit organizations. But how do these government-owned stations combine the advantages of broadcasting and non-profit characteristics with its mission and ideals to create a more positive feedback from its listeners? This must be reached by marketing strategies, and the model of event marketing in a more effective approach to reach the results more immediately. However, government-owned radio stations have limitations as well. No advertising revenue can be gained, nor any type of sponsorship can be accepted. It is worthy to further discuss and determine how marketing strategies can be created for non-profit government-owned radio stations that rely on government funding in order to help them gain maximum benefits without wasting taxpayer contributions or government resources. Among all the government-owned radio stations in Taiwan, the Police Radio Station (PRS) has the largest numbers of channels, the widest listening range, and a good listener rating. So this is a case study on PRS - Caring Traffic Safety Series of Activities, to find out the marketing effectiveness of its broadcast. The results may then be used as a reference for other non-profit government-owned radio stations. Through questionnaire survey and in-depth interview, this study has reached the following findings: the PRS has maintained a positive image among the audience as a “professional traffic radio” that provides traffic reports. However, in a more specific context, the PRS lacks a readily identifiable and impressive logo. Such logo could be a symbol or image of a mascot that would represent the past, present and future of the PRS and further promote its image.
