Communicating Through the Amateur Radio Service:

During the early years of the last century, the advent of radio technology
spawned activity among amateur enthusiasts. The early applications of
wireless communication provided contact with ships at sea long before their
arrival in port. As the level of activity increased, applications of the
new technology became the object of government regulation so that today we
have a variety of services, including the Amateur Radio service, licensed
through the Federal Communications Commission. Collectively, amateur radio
operators pursue various interests engaging in local contacts through
hand-held radios, or in long-distance communication by signal propagation
around the earth, by links through satellites, or by reflection off the
Moon. Depending on their licensed privileges, they may choose from a
variety of modalities (for example, Morse code, digital, and voice). They
communicate casually as conditions permit or by prior arrangement on an
organized local, regional or national basis. Operators may join organized
services to provide backup communications in emergencies to public agencies
and private entities.
