Research by amateur radio operators has founded new industries, built economies, empowered nations, and saved lives in times of emergency. Like other amateur radio frequency allocations, an IP range was provided in 1981 for Amateur Radio Digital Communications (a generic term) and self-administered by radio amateurs. It is used in such applications as telephone trunklines, broadband internet networking cables, high speed computer data busses, carrying cable television signals, and connecting radio transmitters and receivers to their antennas.

A crystal radio receiver, also called a crystal set, is a simple radio receiver, popular in the early days of radio. It uses only the power of the received radio signal to produce sound, needing no external power. At some point in 1976, a new and powerful radio signal was detected simultaneously worldwide, and quickly dubbed 'the Woodpecker' by amateur radio operators.
