Question T1E08
From subelement T1 - T1E
Which of the following is an example of automatic control?
Why is this correct?
Repeater operation is the textbook example of automatic control because repeaters operate without a control operator physically present at the station location. They automatically receive signals on one frequency and retransmit them on another 24/7. Option B (internet control) is remote control, not automatic control, because a control operator is still actively controlling the station from a distance. Options C and D involve computer assistance but still require an operator to initiate and oversee the transmission, making them examples of local control rather than automatic control.
Memory tip
Look for the key distinction: automatic control means no operator intervention needed during operation, while remote control still requires an operator making decisions from elsewhere. If a human is actively controlling or initiating the transmission, it's not automatic control regardless of computer assistance involved.

Under Part 97 regulations, automatic control is strictly limited to specific station types: repeater stations, auxiliary stations, beacon stations, and space stations. These stations serve the amateur community by operating unattended according to predetermined parameters. Repeaters extend communication range by automatically retransmitting signals, while beacons provide propagation information. This limited scope ensures automatic operations serve legitimate amateur purposes while maintaining accountability through designated control operators who can intervene when necessary.
Think about it
Why do you think the FCC restricts automatic control to only certain types of amateur stations rather than allowing any station to operate automatically?
