Which of the following complies with commonly accepted amateur practice when choosing a frequency on which to initiate a call?
The correct answer is C: Follow the voluntary band plan. When choosing a frequency on which to initiate a call, you should follow the voluntary band plan. Band plans organize frequencies by mode and activity, helping prevent interference. For amateur radio operators, following band plans is good operating practice. Understanding this helps ensure proper frequency selection and reduces interference. Band plans are voluntary but widely followed.
Exam Tip
Choose frequency = follow voluntary band plan. Think 'B'and 'P'lan = 'B'est 'P'ractice. Follow the voluntary band plan when choosing a frequency. Band plans organize frequencies by mode and activity. Not about listening time or call sign transmission.

Real-World Application
You want to call CQ on 20 meters. You check the band plan - CW is in the lower portion, SSB phone is in the middle, digital modes are in specific segments. You choose an appropriate frequency for your mode, following the band plan. This helps prevent interference and organizes band usage.
Key Concepts
Why Other Options Are Wrong
Option A: Incorrect. Listening for 2 minutes is good practice but not the requirement - the key is following the band plan for proper frequency selection.
Option B: Incorrect. Transmitting your call sign 3 times isn't required for frequency selection - identification is required during operation, not for choosing frequencies.
Option D: Incorrect. Since A and B are not the primary requirement, 'all of the above' cannot be correct. Following the band plan is the key requirement.
