This book chronicles the history of radio as technology and as media. Radio grew from a clumsy, temperamental form of wireless telegraph to a system that is so ubiquitous and easy to use that it has disappeared to users as a technology and became part of the fabric of human existence. This biography charts the growth of the technical end of radio, starting with the history of electricity, and moving through the invention of vacuum tubes, the heterodyne, FM, transistors, and microchips. But the history of radio is not just wires and electricity--it's the story of strange characters, deep thinkers, visionary mystics, hyperactive minds, ambitious souls, power hungry demagogues, and utopian humanists; all of whom strove to make radio into what they thought it should be. In addition, Radio: The Life Story of a Technology looks at the technology as a cultural phenomenon, including the corporate aspects and history of the business of radio. In the middle of the 20th century people saw that radio could be used as an agent of social change, both good and bad. The transition of radio from private corporate device to public news provider to entertainment box back to political tool is at the heart of this work.

This book provides a detailed review of power amplifiers, including classes and topologies rarely covered in books, and supplies sufficient information to allow the reader to design an entire amplifier system, and not just the power amplification stage. A central aim is to furnish readers with ideas on how to simplify the design process for a preferred power amplifier stage by introducing software-based routines in a programming language of their choice. The book is in two parts, the first focusing on power amplifier theory and the second on EDA concepts. Readers will gain enough knowledge of RF and microwave transmission theory, principles of active and passive device design and manufacturing, and power amplifier design concepts to allow them to quickly create their own programs, which will help to accelerate the transceiver design process. All circuit designers facing the challenge of designing an RF or microwave power amplifier for frequencies from 2 to 18 GHz will find this book to be a valuable asset.

The Square Kilometre Array (SKA) radio telescope is set to become the largest telescope on Earth, and also the largest science project in Africa. From September 2011 to August 2012, the SKA featured regularly in the South African media. In The Stars in Our Eyes, author Michael Gastrow dissects the representation of the SKA in the South African media in the period under discussion. Who were the main actors in this unfolding narrative? Who held the stage and who were marginalised? Where did gatekeeping occur and why? What was the relationship between journalists and scientists? How did the story unfold in the social media as opposed to the print media? Drawing on mass communication theory and science communication theory, The Stars in Our Eyes: Representations of the Square kilometre Array Telescope in the South African Media addresses critical gaps in the literature on science communication, particularly with respect to science communication in an African context.
