The United States ushered in a new era of small-scale broadcasting in 2000 when it began issuing low-power FM (LPFM) licenses for noncommercial radio stations around the country. Over the next ...decade, several hundred of these newly created low-wattage stations took to the airwaves. InLow Power to the People, Christina Dunbar-Hester describes the practices of an activist organization focused on LPFM during this era. Despite its origins as a pirate broadcasting collective, the group eventually shifted toward building and expanding regulatory access to new, licensed stations. These radio activists consciously cast radio as an alternative to digital utopianism, promoting an understanding of electronic media that emphasizes the local community rather than a global audience of Internet users.Dunbar-Hester focuses on how these radio activists impute emancipatory politics to the "old" medium of radio technology by promoting the idea that "microradio" broadcasting holds the potential to empower ordinary people at the local community level. The group's methods combine political advocacy with a rare commitment to hands-on technical work with radio hardware, although the activists' hands-on, inclusive ethos was hampered by persistent issues of race, class, and gender. Dunbar-Hester's study of activism around an "old" medium offers broader lessons about how political beliefs are expressed through engagement with specific technologies. It also offers insight into contemporary issues in media policy that is particularly timely as the FCC issues a new round of LPFM licenses.
The behind-the-scenes story of how admen and sponsors helped shape broadcasting into a popular commercial entertainment medium. During the "golden age" of radio, from roughly the late 1920s until the ...late 1940s, advertising agencies were arguably the most important sources of radio entertainment. Most nationally broadcast programs on network radio were created, produced, written, and/or managed by advertising agencies: for example, J. Walter Thompson produced "Kraft Music Hall" for Kraft; Benton & Bowles oversaw "Show Boat" for Maxwell House Coffee; and Young & Rubicam managed "Town Hall Tonight" with comedian Fred Allen for Bristol-Myers. Yet this fact has disappeared from popular memory and receives little attention from media scholars and historians. By repositioning the advertising industry as a central agent in the development of broadcasting, author Cynthia B. Meyers challenges conventional views about the role of advertising in culture, the integration of media industries, and the role of commercialism in broadcasting history. Based largely on archival materials, A Word from Our Sponsor mines agency records from the J. Walter Thompson papers at Duke University, which include staff meeting transcriptions, memos, and account histories; agency records of BBDO, Benton & Bowles, Young & Rubicam, and N. W. Ayer; contemporaneous trade publications; and the voluminous correspondence between NBC and agency executives in the NBC Records at the Wisconsin Historical Society. Mediating between audiences' desire for entertainment and advertisers' desire for sales, admen combined "showmanship" with "salesmanship" to produce a uniquely American form of commercial culture. In recounting the history of this form, Meyers enriches and corrects our understanding not only of broadcasting history but also of advertising history, business history, and American cultural history from the 1920s to the 1940s.

New Deal Radio examines the federal government's
involvement in broadcasting during the New Deal period, looking at
the U.S. Office of Education's Educational Radio Project. The fact
that the United ...States never developed a national public
broadcaster, has remained a central problem of US broadcasting
history. Rather than ponder what might have been, authors Joy Hayes
and David Goodman look at what did happen. There was in fact a
great deal of government involvement in broadcasting in the US
before 1945 at local, state, and federal levels. Among the federal
agencies on the air were the Department of Agriculture, the
National Park Service, the Works Progress Administration (WPA) and
the Federal Theatre Project. Contextualizing the different series
aired by the Educational Radio Project as part of a unified project
about radio and citizenship is crucial to understanding them.
New Deal Radio argues that this distinctive government
commercial partnership amounted to a critical intervention in US
broadcasting and an important chapter in the evolution of public
radio in America.
Long before the Arab Spring and its use of social media demonstrated the potent intersection between technology and revolution, the Mexican Revolution employed wireless technology in the form of ...radiotelegraphy and radio broadcasting to alter the course of the revolution and influence how political leaders reconstituted the government.Radio in Revolution, an innovative study of early radio technologies and the Mexican Revolution, examines the foundational relationship between electronic wireless technologies, single-party rule, and authoritarian practices in Mexican media. J. Justin Castro bridges the Porfiriato and the Mexican Revolution, discussing the technological continuities and change that set the stage for Lázaro Cárdenas's famous radio decree calling for the expropriation of foreign oil companies.Not only did the nascent development of radio technology represent a major component in government plans for nation and state building, its interplay with state power in Mexico also transformed it into a crucial component of public communication services, national cohesion, military operations, and intelligence gathering. Castro argues that the revolution had far-reaching ramifications for the development of radio and politics in Mexico and reveals how continued security concerns prompted the revolutionary victors to view radio as a threat even while they embraced it as an essential component of maintaining control.
RF circuit design is now more important than ever as we find ourselves in an increasingly wireless world. Radio is the backbone of today’s wireless industry with protocols such as Bluetooth, Wi-Fi, ...WiMax, and ZigBee. Most, if not all, mobile devices have an RF component and this book tells the reader how to design and integrate that component in a very practical fashion. This book has been updated to include today's integrated circuit (IC) and system-level design issues as well as keeping its classic "wire lead" material. Design concepts and tools includes:The Basics: Wires, Resistors, Capacitors, InductorsResonant Circuits: Resonance, Insertion Loss Filter Design: High-pass, Bandpass, Band-rejectionImpedance Matching: The L Network, Smith Charts, Software Design ToolsTransistors: Materials, Y Parameters, S ParametersSmall Signal RF Amplifier: Transistor Biasing, Y Parameters, S ParametersRF Power Amplifiers: Automatic Shutdown Circuitry , Broadband Transformers, Practical Winding HintsRF Front-End: Architectures, Software-Defined Radios, ADC’s EffectsRF Design Tools: Languages, Flow, Modeling
We have performed a search over 3440 deg2 of Epoch 1 (2017-2019) of the Very Large Array Sky Survey to identify unobscured quasars in the optical (0.2 < z < 3.2) and obscured active galactic nuclei ...(AGNs) in the infrared that have brightened dramatically in the radio over the past one to two decades. These sources would have been previously classified as "radio-quiet" quasars based on upper limits from the Faint Images of the Radio Sky at Twenty cm survey (1993-2011), but they are now consistent with "radio-loud" quasars ( ). A quasi-simultaneous, multiband (∼1-18 GHz) follow-up study of 14 sources with the VLA has revealed compact sources (<0 1 or <1 kpc) with peaked radio spectral shapes. The high-amplitude variability over decadal timescales at 1.5 GHz (100% to >2500%) but roughly steady fluxes over a few months at 3 GHz are inconsistent with extrinsic variability due to propagation effects, thus favoring an intrinsic origin. We conclude that our sources are powerful quasars hosting compact/young jets. This challenges the generally accepted idea that "radio-loudness" is a property of the quasar/AGN population that remains fixed on human timescales. Our study suggests that frequent episodes of short-lived AGN jets that do not necessarily grow to large scales may be common at high redshift. We speculate that intermittent but powerful jets on subgalactic scales could interact with the interstellar medium, possibly driving feedback capable of influencing galaxy evolution.
The march to the Trump presidency began in 1988, when Rush Limbaugh went national. Brian Rosenwald charts the transformation of AM radio entertainers into political kingmakers. By giving voice to the ...conservative base, they reshaped the Republican Party and fostered demand for a president who sounded as combative and hyperbolic as a talk show host.

Zulu Radio in South Africa is one of the most far-reaching and influential media in the region, currently attracting around 6.67 million listeners daily. While the public and political role of radio ...is well-established, what is less understood is how it has shaped culture by allowing listeners to negotiate modern identities and fast-changing lifestyles. Liz Gunner explores how understandings of the self, family, and social roles were shaped through this medium of voice and mediated sound. Radio was the unseen literature of the auditory, the drama of the airwaves, and thus became a conduit for many talents squeezed aside by apartheid repression. Besides Winnie Mahlangu and K. E. Masinga, among other talents, the exiles Lewis Nkosi and Bloke Modisane made a network of identities and conversations which stretched from the heart of Harlem to the American South, drawing together the threads of activism and creativity from both Black America and the African continent at a critical moment of late empire.

As World War II drew to a close and radio news was popularized through overseas broadcasting, journalists and dramatists began to build upon the unprecedented success of war reporting on the radio by ...creating audio documentaries. Focusing particularly on the work of radio luminaries such as Edward R. Murrow, Fred Friendly, Norman Corwin, and Erik Barnouw, Radio Utopia: Postwar Audio Documentary in the Public Interest traces this crucial phase in American radio history, significant not only for its timing immediately before television, but also because it bridges the gap between the end of the World Wars and the beginning of the Cold War._x000B__x000B_Matthew C. Ehrlich closely examines the production of audio documentaries disseminated by major American commercial broadcast networks CBS, NBC, and ABC from 1945 to 1951. Audio documentary programs educated Americans about juvenile delinquency, slums, race relations, venereal disease, atomic energy, arms control, and other issues of public interest, but they typically stopped short of calling for radical change. Drawing on rare recordings and scripts, Ehrlich traces a crucial phase in the evolution of news documentary, as docudramas featuring actors were supplanted by reality-based programs that took advantage of new recording technology. Paralleling that shift from drama to realism was a shift in liberal thought from dreams of world peace to uneasy adjustments to a cold war mentality._x000B__x000B_Influenced by corporate competition and government regulations, radio programming reflected shifts in a range of political thought that included pacifism, liberalism, and McCarthyism. In showing how programming highlighted contradictions within journalism and documentary, Radio Utopia reveals radio's response to the political, economic, and cultural upheaval of the post-war era.
