This comprehensive guide helps readers understand the theory and techniques needed to analyze and model radio wave propagation in complex environments. All of the essential topics are covered, from the fundamental concepts of radio systems, to complex propagation phenomena. These topics include diffraction, ray tracing, scattering, atmospheric ducting, ionospheric ducting, scintillation, and propagation through both urban and non-urban environments. Emphasis is placed on practical procedures, with detailed discussion of numerical and mathematical methods providing readers with the necessary skills to build their own propagation models and develop their own techniques. MATLAB functions illustrating key modeling ideas are provided online. This is an invaluable resource for anyone wanting to use propagation models to understand the performance of radio systems for navigation, radar, communications, or broadcasting.

This book shall help shortwave listener to identify stations on shortwave. It contains more then 18000 frequencies from 82 Hz to 30000 kHz.

Information was collected in three different ways; a review of the literature, qualitative data from semi-structured interviews and quantitative questionnaires. A comprehensive review of current literature showed that usability is just as important as a technological approach for mobile phone design. It was also apparent from the literature that Nokia and Microsoft still value a user centred design approach as they continue to evolve their partnership. Qualitative data was gathered from semi-structured interviews with three design industry experts. Information from this part of the research yielded many important findings in particular the viewpoint that mobile phones will increasingly become a commodity that may hinder the design approach taken by the Nokia and Microsoft collaboration. Finally, 35 participants were also contacted to complete a questionnaire that targets consumers' attitudes towards aspects of their mobile phone. Results revealed that users still value their user interface style, however when they were asked if they would switch to a different phone, the data indicated that their decision to switch would be due to hardware performance rather than interface style.

This book describes the origin, growth, and achievements of school broadcasting in Canada. Sections are devoted to the start of school broadcasting in each province, the establishment of national school broadcasts, and the work of the National Advisory Council on School Broadcasting. In the story, the part played by the Canadian Broadcasting Corporation in initiating and promoting the work of teaching by radio and in providing the facilities upon which it is based, is a significant one. The book is the first authoritative description, by the man largely responsible for its success, of an important and fruitful experiment in federal-provincial co-operation in the thorny field of education. To this co-operation is due the high standard of the school broadcasts which have earned for Canada world-wide recognition and appreciation. The book also describes the international aspects of this cooperation, particularly between Canada and Australia, Great Britain, and the United States.

How Spanish-language radio has influenced American and Latino discourse on key current affairs issues such as citizenship and immigration. Winner, Book of the Year presented by the American Association of Hispanics in Higher Education Honorable Mention for the 2015 Latino Studies Best Book presented by the Latin American Studies Association The last two decades have produced continued Latino population growth, and marked shifts in both communications and immigration policy. Since the 1990s, Spanish- language radio has dethroned English-language radio stations in major cities across the United States, taking over the number one spot in Los Angeles, Houston, Miami, and New York City. Investigating the cultural and political history of U.S. Spanish-language broadcasts throughout the twentieth century, Sounds of Belonging reveals how these changes have helped Spanish-language radio secure its dominance in the major U.S. radio markets. Bringing together theories on the immigration experience with sound and radio studies, Dolores Ines Casillas documents how Latinos form listening relationships with Spanish-language radio programming. Using a vast array of sources, from print culture and industry journals to sound archives of radio programming, she reflects on institutional growth, the evolution of programming genres, and reception by the radio industry and listeners to map the trajectory of Spanish-language radio, from its grassroots origins to the current corporate-sponsored business it has become. Casillas focuses on Latinos' use of Spanish-language radio to help navigate their immigrant experiences with U.S. institutions, for example in broadcasting discussions about immigration policies while providing anonymity for a legally vulnerable listenership. Sounds of Belonging proposes that debates of citizenship are not always formal personal appeals but a collective experience heard loudly through broadcast radio.

This research aims to present accurate computer models of a communication link and a Super High Frequency (SHF) radio communication system. Network Warfare Simulation (NETWARS) is a J-6 initiative aimed at modeling all communication traffic in the Department of Defense (DoD) for testing and analysis of specific real world scenarios. The AN/TSC-94 is a SHF radio system with satellite communication capabilities. The AN/TSC-94 incorporates a Direct Sequence Spread Spectrum (DSSS) radio link for certain Anti-Jam (AJ) features. A DSSS 'spreads' signal power over a large bandwidth, reducing power previously concentrated within the original system bandwidth. The simulations were performed using OPNET. Simulation results show DSSS lowered Bit Error Rate (BER) over links not using spread spectrum. Results show that in the presence of multiple jamming forms, the DSSS link performed without bit errors while the normal (non-DSSS) link was disrupted by the jammer, experiencing BER's of up to 0.43. The AN/TSC-94 was able to defeat the jammer using the DSSS link. By performing in normal mode during unjammed scenarios, and switching to AJ mode in the presence of a hostile transmitter, the AN/TSC-94 demonstrated its ability to successfully communicate in multiple access and hostile environments.

Charlie Edwards spent many years in the broadcasting industry. Most of that time was in Christian radio. This booklet was first published in 1983 as the result of preachers asking questions about how they can start or improve their radio ministry. In 2013 this booklet was updated by the author with modern technology. It has once again been made available to preachers who are interested in getting the message of Christ out in their communities by radio. Charlie Edwards is certified with the Society of Broadcast Engineers as a Certified Broadcast Television, Radio, and Audio Engineer.
