The Radio Amateur is:
Considerate: never knowingly operates in such a way as to lessen the pleasure of others.
Loyal: offers loyalty, encouragement and support to other amateurs, local clubs, and the American Radio Relay League, through which Amateur Radio in the United States is represented nationally and internationally.
Progressive: with knowledge abreast of science, a well-built and efficient station and operation above reproach.
Friendly: slow and patient operating when requested; friendly advice and counsel to the beginner; kindly assistance, cooperation and consideration for the interests of others. These are the hallmarks of the amateur spirit.
Balanced: radio is an avocation, never interfering with duties owed to family, job, school or community.
Patriotic: station and skill always ready for service to country and community.
—The original Amateur’s Code was written by Paul M. Segal, W9EEA, in 1928.
