What type of amateur station simultaneously retransmits the signal of another amateur station on a different channel or channels?

• A. Repeater station
• B. Base station
• C. Mobile station
• D. Satellite station

Answer: (A)

A repeater station is designed specifically to receive a signal from one amateur station and then retransmit that signal on a different frequency. This allows for extended communication range, as the repeater can be located on a high point, effectively allowing signals to reach areas that would be difficult for a fixed or mobile station to cover directly. The function of a repeater is crucial in amateur radio, particularly for facilitating communication over long distances and across challenging terrain.

Base stations, mobile stations, and satellite stations serve different purposes in the realm of amateur radio. A base station typically refers to a stationary setup from which an operator can communicate, while a mobile station involves equipment set up within a vehicle for operation during travel. Satellite stations utilize orbiting satellites to relay communications, but they do not function like repeaters in the terrestrial sense of receiving and retransmitting a direct amateur radio signal. Thus, a repeater station is uniquely characterized by its purpose and function among amateur radio stations.
