Amateur radio station

An amateur radio station is a radio station designed to provide radiocommunications in the amateur radio service for an amateur radio operator. Radio amateurs build and operate several types of amateur radio stations, including fixed ground stations, mobile stations, space stations, and temporary field stations. A slang term often used for an amateur station's location is the shack, named after the small enclosures added to the upperworks of naval ships to hold early radio equipment and batteries.

An amateur radio station established in a permanent structure with equipment that is not intended for portable operation is referred to as a fixed station. This is the most common form of amateur radio station, and can be found in homes, schools, and some public buildings. A typical fixed station is equipped with a transceiver and one or more antennas. For voice communications, the station will be equipped with a microphone; for communications using the Morse code, a telegraph key is common; and for communications over digital modes such as RTTY and PSK31, a station will be equipped with a specialized interface to connect the transceiver to a computer sound card. While not a requirement for radiocommunications, most fixed amateur radio stations are equipped with one or more computers, which serve tasks ranging from logging of contacts with other stations to various levels of station hardware control. Fixed stations might also be equipped with amplifiers, antenna rotators, SWR meters, and other station accessories.

Fixed stations are generally powered from the AC mains electrical supply available in the building. Some equipment in fixed stations may run off low voltage DC instead of AC, and require a separate power supply. Some fixed stations are equipped with auxiliary sources of power, such as electrical generators or batteries for use in emergencies.
