Question T1F09
From subelement T1 - T1F
What type of amateur station simultaneously retransmits the signal of another amateur station on a different channel or channels?
Why is this correct?
A repeater station is specifically designed to simultaneously receive signals on one frequency and retransmit them on a different frequency, extending communication range. This dual-frequency operation distinguishes repeaters from other station types. Beacon stations only transmit identification signals, earth stations communicate with satellites, and message forwarding stations store and forward messages rather than simultaneously retransmitting.
Memory tip
Remember the key word 'simultaneously' - this eliminates stations that store-and-forward or only transmit. Look for questions asking about real-time signal relay between different frequencies, which is the repeater's unique function among amateur station types.

Repeaters operate under automatic control provisions in Part 97, allowing 24/7 operation without constant human oversight. They form the backbone of emergency communication networks, extending VHF/UHF coverage from mountaintops to valleys. The FCC categorizes repeaters alongside auxiliary and space stations as the only amateur stations permitted to automatically retransmit other stations' signals, reflecting their critical infrastructure role.
Think about it
Why do you think the FCC allows repeaters to operate automatically without a control operator physically present, when most amateur stations require direct human control?
