Each year, students in Kittanning Senior High School's Principles of Technology (POT) classes have a design challenge, usually beginning with CO2-powered or Maglev-powered vehicles and progressing to such challenges as soap-box cars or radio-controlled airplanes. The author's recent POT class challenged them with the most exciting challenge yet:…

Radio is a relatively simple and effective way to make campus news and information available to the public. Establishing a college radio news service is not difficult, and developing a sound-bite service requires little equipment or expertise, just careful attention to quality and technique. More sophisticated systems can be developed easily. (MSE)

Times are tough for everyone, including public school districts. During the past decade, school districts have faced the dual challenges of tightening budgets and increasing fiscal responsibility and oversight. Many school districts have found a way to manage their assets, reduce staff requirements, increase accountability, and save money on…

The history of pirate radio--radio broadcasts offered by unlicensed broadcasters as alternatives to licensed, commercial radio programming--is difficult to trace, both in America and the United Kingdom (UK) since mention of pirate broadcasts of a less-then-thrilling nature are rarely found. Also, until 1927, the U.S. government did not formally…

This article describes one of the first developments and deployment of radio for distance learning and education in Canada, beginning in the early 1920s. Anticipating a recent initiative of public-private partnerships, the impetus, infrastructure, and initial programs were provided by a large corporation. Description of the system, its purpose,…

Radar is a technology that can be used to detect distant objects not visible to the human eye. A predecessor of radar, called the telemobiloscope, was first used to detect ships in the fog in 1904 off the German coast. Many scientists have worked on the development and refinement of radar (Hertz with electromagnetic waves; Popov with determining…

Podcasting is just one of a suite of new tools that are taking the Internet and its users to new heights. Podcasting involves the creation of digital audio files and the distribution of those files in a way that makes it easy for visitors to listen to them wherever and whenever it is convenient. In schools, podcasts have been quick to take root.…

Describes practical applications related to X-rays, ultra-violet radiation, light radiation, short-wave infra-red radiation, medium-wave infra-red radiation, long-wave infra-red radiation, microwave radiation, and radio frequency radiation. Suggests that these applications be used during instruction on electricity. (JN)

In this age of cell phones, digital television, and satellite radio, individuals easily forget that information and energy must undergo complex transformations to enable real-time wireless communication. This article describes a practical and proven design activity that enables secondary and post-secondary students to design and test a modulator…

It is difficult to obtain reliable data on the nature of the audience for international broadcast programs in Asia (e.g., those beamed by the Voice of America or Radio Japan). However, analysis of listener mail and some survey research have provided a fairly clear profile of the audience: young (ages 15-34), well educated, urban, male (but with a…

Two short articles describe some unusual educational radio programing. A program on African literature is broadcast by the Iowa State University radio station and consists of discussions, talks and readings. Programs are transcribed onto cassettes and kept in the university library. The second article notes that Radio Cairo has produced a textbook…

This issue of the Language by Radio Interest Group newsletter contains: an article by Paul A. Gaeng on his experience as a radio listener, an article by Richard E. Wood on "Radio Peking," and a partial reprint of frequency listings from the January 1976 number. Gaeng reports that, when he was a student in Geneva, he developed skills as a…

Describes an inexpensive apparatus for the detection of gravity waves traveling through the ionosphere. The detector consists of a modified transistor radio with a ferrite-core antenna. Numerous diagrams accompany a lengthy description. (CS)

Rural Radio (RR) in Dahomey has a radio network that covers most of the national territory with two transmitters plus 4KW short wave. The program themes are suggested by an advisory group from interested ministries such as Education, Youth and Sport, Agriculture, Health, etc., but the primary objective of the project lies in promoting dialogues…
