by Paul M. Segal, W9EEA (1928)

The Radio Amateur is:

CONSIDERATE   never knowingly operating in such a way as to lessen the pleasure of others.

LOYAL                  offering 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 beyond reproach.

FRIENDLY            with slow and patient operation when requested, friendly advice and counsel to the beginner, kindly assistance, co-operation 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          with station and skill always ready for service to country and community
