Which of the following is a purpose of a beacon station as identified in the FCC rules?
The correct answer is A: Observation of propagation and reception. A purpose of a beacon station as identified in the FCC rules is observation of propagation and reception. Beacons transmit continuously to help operators observe band conditions, propagation patterns, and reception quality. This is the primary regulatory purpose of beacons. For amateur radio operators, beacons are valuable tools for assessing band conditions and propagation. Understanding this helps explain why beacons are permitted and how they're used.
Exam Tip
Beacon purpose = propagation observation. Think 'B'eacon = 'B'and condition 'O'bservation. Primary purpose is to observe propagation and reception conditions. Not for repeater ID or bulletins - just propagation observation.
Memory Aid
"Beacon purpose = propagation observation. Think 'B'eacon = 'B'and condition 'O'bservation. Primary regulatory purpose is observation of propagation and reception. Helps assess band conditions."
Real-World Application
You monitor a 20-meter beacon to assess band conditions. The beacon's signal strength and quality tell you about propagation - is the band open? How strong are signals? This propagation observation is the regulatory purpose of beacons. They help operators understand band conditions.
Key Concepts
Why Other Options Are Wrong
Option B: Incorrect. Beacons aren't for automatic repeater identification - that's what repeater identification systems do. Beacons are for propagation observation.
Option C: Incorrect. Beacons aren't for transmitting bulletins - that's what bulletin stations do. Beacons are specifically for propagation observation.
Option D: Incorrect. Since B and C are not beacon purposes, 'all of the above' cannot be correct. Only propagation observation is the regulatory purpose.
