Question T1D07
From subelement T1 - T1D
What types of amateur stations can automatically retransmit the signals of other amateur stations?
Why is this correct?
Only repeater, auxiliary, and space stations are authorized for automatic retransmission under Part 97. Repeaters extend coverage by receiving and simultaneously retransmitting on different frequencies. Auxiliary stations support local amateur networks with automatic relay functions. Space stations include amateur satellites that automatically relay signals. Beacon and Earth stations don't have automatic retransmission privileges—beacons only transmit identification signals, while Earth stations communicate with satellites but don't automatically retransmit other stations' signals.
Memory tip
Remember the three-station pattern: stations that extend coverage or support networks get automatic retransmission privileges. Think 'relay-capable' stations versus 'endpoint' stations. Beacons and Earth stations are endpoints in the communication chain, while repeaters, auxiliary, and space stations actively relay signals between other stations.

These three station types share automatic retransmission privileges because they serve as relay infrastructure for the amateur service. Repeaters provide wide-area coverage extension, auxiliary stations create local network links following frequency coordination protocols, and space stations enable satellite relay operations. Each operates under specific emission standards and frequency privileges defined in Part 97, requiring proper control operator oversight even during automatic operation periods.
Think about it
Why do you think beacon stations aren't permitted to automatically retransmit other stations' signals, even though they operate automatically?
