Amateur radio (also called ham radio) describes the use of radio frequency spectrum for purposes of non-commercial exchange of messages, wireless experimentation, self-training, private recreation, radiosport, contesting, 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).

Technology ("science of craft", from Greek, techne, "art, skill, cunning of hand"; and) is the collection of techniques, skills, s and processes used in the production of goods or services or in the accomplishment of objectives, such as scientific investigation.

Technology can be the knowledge of techniques, processes, and the like, or it can be embedded in machines which can be operated without detailed knowledge of their workings.

The ampere (SI unit symbol: A, dimension symbol: I), often shortened to "amp", is a unit of electric current.

In the International System of Units (SI) the ampere is one of the seven SI base units.

It is named after André-Marie Ampère (1775–1836), French mathematician and physicist, considered the father of electrodynamics.

Software-defined radio (SDR) is a radio communication system where components that have been typically implemented in hardware (e.g. mixers, filters, amplifiers, modulators/demodulators, detectors, etc) are instead implemented by means of software on a personal computer or embedded system.

While the concept of SDR is not new, the rapidly evolving capabilities of digital electronics render practical many processes which used to be only theoretically possible.

Radio is the technology of using radio waves to carry information, such as sound, by systematically modulating properties of electromagnetic energy waves transmitted through space, such as their amplitude, frequency, phase, or pulse width.

When radio waves strike an electrical conductor, the oscillating fields induce an alternating current in the conductor.

The information in the waves can be extracted and transformed back into its original form.
