Which of the following is required by the FCC rules when operating in the 60-meter band?
The correct answer is A: If you are using an antenna other than a dipole, you must keep a record of the gain of your antenna. A requirement when operating in the 60-meter band is that if you are using an antenna other than a dipole, you must keep a record of the antenna gain. This helps ensure compliance with the ERP (Effective Radiated Power) limit on 60 meters. For amateur radio operators, this record-keeping requirement applies when using directional or high-gain antennas. Understanding this helps ensure legal operation on 60 meters.
Exam Tip
60-meter requirement = antenna gain record for non-dipole antennas. Think '6'0 meters = 'A'ntenna 'G'ain record if not dipole. Must keep record of antenna gain when using antennas other than dipoles. Not about operating logs, third-party traffic, or equipment records.
Memory Aid
"60-meter requirement = antenna gain record for non-dipole. Think '6'0 meters = 'A'ntenna 'G'ain record. Must keep record of antenna gain when using antennas other than dipoles. Helps ensure ERP compliance."
Real-World Application
You operate on 60 meters using a 3-element Yagi antenna with 8 dB gain. Since you're not using a dipole, you must keep a record of your antenna's gain (8 dB). This helps ensure you comply with the ERP limit on 60 meters. If you used a dipole, no gain record would be needed.
Key Concepts
Why Other Options Are Wrong
Option B: Incorrect. You don't need to keep records of date, time, frequency, power, and stations worked on 60 meters - that's not a requirement. Only antenna gain records are required for non-dipole antennas.
Option C: Incorrect. You don't need to keep records of third-party traffic on 60 meters - that's not a requirement. Only antenna gain records are required.
Option D: Incorrect. You don't need to keep records of equipment manufacturer and antenna used - that's not a requirement. Only antenna gain records are required for non-dipole antennas.
