An amateur radio operator is someone who uses equipment at an amateur radio station to engage in two-way personal communications with other amateur operators on radio frequencies assigned to the amateur radio service. Amateur radio operators have been granted an amateur radio license by a governmental regulatory authority after passing an examination on applicable regulations, electronics, radio theory, and radio operation. As a component of their license, amateur radio operators are assigned a call sign that they use to identify themselves during communication. There are about three million amateur radio operators worldwide. Amateur radio operators are also known as radio amateurs or hams.

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.
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. 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 fixed stations are equipped with auxiliary sources of power, such as electrical generators or batteries for use in emergencies.
An amateur radio station installed in a vehicle is referred to as a mobile station. The transceiver may be specially designed for installation in vehicles. It may be much smaller than transceivers designed for fixed station use, to facilitate installation under a seat or in a trunk, and it may feature a detachable control head that can be mounted in a separate location from the rest of the radio.
Antennas designed for mobile stations must accommodate the unique physical constraints of the vehicle and travel lanes which it occupies, allowing for clearance under overpasses and bridges, and safe passage by vehicles in adjacent lanes.
Few mobile stations are equipped to communicate with Morse code or digital modes. A specialized form of mobile station used for competition in a VHF amateur radio contest in North America is called a rover station.
Maritime mobile stations are mobile stations installed in a watercraft, usually an ocean-going vessel. When in international waters, these stations are operated under the regulatory authority of the flag under which the vessel is registered. In addition to the regulatory requirements of amateur radio, operation of maritime mobile stations also requires the permission of the captain of the vessel. Aeronautical mobile stations are mobile stations installed in an aircraft.
In addition to the regulatory requirements of amateur radio, operation of aeronautical mobile stations also requires the permission of the pilot of the aircraft. An amateur radio station set up in a temporary location is referred to as a portable station. A portable stations might be established to provide emergency communications in a disaster area, to provide public service communications during a large organized event such as a charity bicycle ride, to provide communications during an expedition, or for the recreational enjoyment of operating outdoors.
Portable stations include the same basic equipment as fixed and mobile stations, although transportation of the transceiver, antennas, power supplies or batteries and necessary accessories often influences the particular selection. Equipment that does not weigh very much, or that can be broken down for shipment or transportation in luggage is especially popular with amateur radio operators travelling on DX-peditions. Because this form of power might be of limited supply, portable stations often operate at lower transmitter power output to conserve energy.
In some countries, this is a regulatory requirement, whereas in others it is done at the option of the operator. An amateur radio station that is located in a satellite , the Space Shuttle , or on the International Space Station is referred to as a space station. Some countries, including the United States , have additional or different regulations regarding the operation of space stations than other amateur radio stations.
These stations are frequently either transponders or repeaters that operate under automatic control and can be used by ground stations any station that is not a space station to relay their signal to other ground stations.
Handheld radios contain all the necessary equipment for radiocommunications with another station. A typical radio used as a handheld station integrates a transceiver with an antenna and a battery in one handheld package. To conserve battery power, they have limited transmitter power, often below 1W, to cover a local range of typically a few km or miles.
An amateur radio repeater is a specialty amateur radio station that extends the range of communications for other stations. A repeater uses a receiver tuned to one radio frequency and a transmitter tuned to another radio frequency. Other stations using a repeater station transmit on one frequency but listen for signals on the other frequency. If a repeater station is in a favorable location, such as on a tall tower, the top of a tall building, or on a mountaintop, stations that otherwise would not be able to communicate with each other can each use the repeater and establish two-way communications.
Repeater stations generally operate under automatic control. The control equipment is responsible for transmitting the repeater station's call sign at regular intervals. This identification is often done in Morse code. Some modern amateur transceivers have embedded computers with firmware which is executed to provide the functions and features of the transceiver.
This software must be provided by the original manufacturer of the equipment. Another type of software is that required to control a receiver or transceiver without a front panel provided. These ports are useful for satellite-tracking frequency control Doppler tuning , station logging, digital operation, internet and special-needs accessibility.
In many cases, the software adds improved or extra functions and features beyond that provided by the original design. For this reason, some operators purchase radio-control software for non-computerized operation even if their radio has a front control panel. During transmissions, an amateur radio station must identify itself with a call sign issued by the authorized regulatory authority of the country in which the station is located.
An amateur radio station may be operated under the call sign of the owner of the station or the call sign of the operator of the station. In some countries, special call signs might be made available for clubs, and are frequently used at a club station established for use of the club's members.

Morse, using internationally agreed message encodings such as the Q code , enables communication between amateurs who speak different languages. The greater than 2 MeV electron flux at geosynchronous orbit is expected to reach moderate levels on 24 Oct, Nov, and again on Nov. A few small countries may not have a national licensing process and may instead require prospective amateur radio operators to take the licensing examinations of a foreign country.
