Question T1D02
From subelement T1 - T1D
Under which of the following circumstances are one-way transmissions by an amateur station prohibited?
Why is this correct?
Broadcasting is prohibited because the FCC defines it as transmissions intended for the general public. Amateur radio serves licensed operators, not the general public. One-way transmissions are allowed for specific purposes like Morse code practice (choice C), telecommand/telemetry (choice D), beacon stations, and emergency communications. Choice A is wrong because legitimate one-way uses exist within amateur radio's authorized purposes.
Memory tip
Look for the recipient distinction: amateur radio serves licensed operators and authorized purposes, while broadcasting serves the general public. When evaluating transmission restrictions, ask 'who is the intended audience?' This pattern applies across many amateur radio regulations.

Part 97.113(b) specifically prohibits broadcasting while allowing other one-way transmissions under Part 97.3(a)(10)'s definition. In practice, this means you can transmit CW practice, operate beacon stations for propagation studies, send telemetry from your weather station, or control model aircraft—all legitimate amateur purposes. However, transmitting music, news, or entertainment for anyone to hear crosses into broadcasting territory and violates your frequency privileges.

Why do you think the FCC allows one-way transmissions for technical purposes like telemetry and beacons, but prohibits broadcasting to the general public?
