From the early 20th century, Electronics & Communications areas were leading to subsequent S&T innovations including in space science & artificial intelligence of today. In this effort, a major role is played by Amateur Radio / Ham Radio operators. They are called Hams when they get licenses from Govts. Anyone over 12 years can get license. Ever since Wireless was invented Hams from all walks of life from Kings to commoners i.e high professionals to amateurs including students were using wireless spectrum allocated free of cost by ITU to Hams. They carry out experiments and communicate anywhere in the world and also benefit from it. This book speaks of various aspects of Ham Radio and how to go about also explains the tremendous potential to gain skills in S&T, and to engage in activities that can lead to good employment for thousands of youth besides enjoying communications with all in the world using wireless free of cost. Book also explains how advanced nations became economic powers using Hams as a resource. Further speaks about how it is relevant today to Governments, universities and Industry benefit from these Hams

A history of ham radio culture: how ham radio enthusiasts formed identity and community through their technical hobby, from the 1930s through the Cold War. Decades before the Internet, ham radio provided instantaneous, global, person-to-person communication. Hundreds of thousands of amateur radio operators--a predominantly male, middle- and upper-class group known as hams--built and operated two-way radios for recreation in mid twentieth century America. In Ham Radio's Technical Culture, Kristen Haring examines why so many men adopted the technical hobby of ham radio from the 1930s through 1970s and how the pastime helped them form identity and community. Ham radio required solitary tinkering with sophisticated electronics equipment, often isolated from domestic activities in a radio shack, yet the hobby thrived on fraternal interaction. Conversations on the air grew into friendships, and hams gathered in clubs or met informally for eyeball contacts. Within this community, hobbyists developed distinct values and practices with regard to radio, creating a particular technical culture. Outsiders viewed amateur radio operators with a mixture of awe and suspicion, impressed by hams' mastery of powerful technology but uneasy about their contact with foreigners, especially during periods of political tension. Drawing on a wealth of personal accounts found in radio magazines and newsletters and from technical manuals, trade journals, and government documents, Haring describes how ham radio culture rippled through hobbyists' lives. She explains why hi-tech employers recruited hams and why electronics manufacturers catered to these specialty customers. She discusses hams' position within the military and civil defense during World War II and the Cold War as well as the effect of the hobby on family dynamics. By considering ham radio in the context of other technical hobbies--model building, photography, high-fidelity audio, and similar leisure pursuits--Haring highlights the shared experiences of technical hobbyists. She shows that tinkerers influenced attitudes toward technology beyond hobby communities, enriching the general technical culture by posing a vital counterpoint.

The overlooked history of an early appropriation of digital technology: the creation of games though coding and hardware hacking by microcomputer users. From the late 1970s through the mid-1980s, low-end microcomputers offered many users their first taste of computing. A major use of these inexpensive 8-bit machines--including the TRS System 80s and the Sinclair, Atari, Microbee, and Commodore ranges--was the development of homebrew games. Users with often self-taught programming skills devised the graphics, sound, and coding for their self-created games. In this book, Melanie Swalwell offers a history of this era of homebrew game development, arguing that it constitutes a significant instance of the early appropriation of digital computing technology. Drawing on interviews and extensive archival research on homebrew creators in 1980s Australia and New Zealand, Swalwell explores the creation of games on microcomputers as a particular mode of everyday engagement with new technology. She discusses the public discourses surrounding microcomputers and programming by home coders; user practices; the development of game creators' ideas, with the game Donut Dilemma as a case study; the widely practiced art of hardware hacking; and the influence of 8-bit aesthetics and gameplay on the contemporary game industry. With Homebrew Gaming and the Beginnings of Vernacular Digitality, Swalwell reclaims a lost chapter in video game history, connecting it to the rich cultural and media theory around everyday life and to critical perspectives on user-generated content.
