On the Road

On the Road is a novel by American writer Jack Kerouac, based on the travels of Kerouac and his friends across America. It is considered a defining work of the postwar Beat and Counterculture generations, with its protagonists living life against a backdrop of jazz, poetry, and drug use. The novel, published in 1957, is a roman à clef, with many key figures in the Beat movement, such as William S. Burroughs (Old Bull Lee), Allen Ginsberg (Carlo Marx) and Neal Cassady (Dean Moriarty) represented by characters in the book, including Kerouac himself as the narrator Sal Paradise.

The idea for On the Road, Kerouac's second novel, was formed during the late 1940s in a series of notebooks, and then typed out on a continuous reel of paper during three weeks in April 1951. It was first published by Viking Press in 1957. After several film proposals dating from 1957, the book was finally made into a film, On the Road (2012), produced by Francis Ford Coppola and directed by Walter Salles.

Amateur radio

Amateur radio (also called ham radio) describes the use of radio frequency spectra for purposes of non-commercial exchange of messages, wireless experimentation, self-training, private recreation and emergency communication. The term "amateur" is used to specify "a duly authorised person interested in radioelectric practice with a purely personal aim and without pecuniary interest;" (either direct monetary or other similar reward) and to differentiate it from commercial broadcasting, public safety (such as police and fire), or professional two-way radio services (such as maritime, aviation, taxis, etc.).

The amateur radio service (amateur service and amateur-satellite service) is established by the International Telecommunication Union (ITU) through the International Telecommunication Regulations. National governments regulate technical and operational characteristics of transmissions and issue individual stations licenses with an identifying call sign. Prospective amateur operators are tested for their understanding of key concepts in electronics and the host government's radio regulations. Radio amateurs use a variety of voice, text, image, and data communications modes and have access to frequency allocations throughout the RF spectrum to enable communication across a city, region, country, continent, the world, or even into space.
