Question T1A06
From subelement T1 - T1A
What is the FCC Part 97 definition of a beacon?
Why is this correct?
A beacon is specifically defined in Part 97 as an amateur station that transmits to observe propagation or conduct experimental activities. Option D matches this exact definition. The incorrect choices describe government services (A), emergency bulletins (B), or weather transmissions (C) - none of which are amateur beacon stations as defined by FCC regulations.
Memory tip
Look for the key phrase 'amateur station' in beacon definitions - it distinguishes amateur beacons from all other types of transmissions. Government or commercial services aren't amateur stations, making those options automatically incorrect regardless of their function.

Amateur beacon stations serve as propagation monitors, automatically transmitting on known frequencies so operators worldwide can assess band conditions. They're particularly valuable on HF bands where ionospheric conditions constantly change. By listening for distant beacons, you can determine if a frequency is 'open' for long-distance communication before attempting contacts. This real-time propagation assessment helps amateur operators choose appropriate frequencies and power levels for successful communications.
Think about it
Why do you think beacon stations are more commonly found on HF bands rather than VHF or UHF frequencies?
