Deep Dive: T2A02
The correct answer is A: 146.520 MHz. This is the national calling frequency for FM simplex operations on the 2-meter band. According to standard band plans, 146.52 MHz is designated as the calling frequency where operators can make initial contact before moving to another frequency for their conversation. This frequency is widely recognized and monitored by many operators, especially when traveling. It's the standard place to make initial contact on 2-meter FM simplex. After making contact, operators typically move to another frequency (like 146.55, 146.58, etc.) to continue their conversation, leaving 146.52 clear for others to make initial contacts.
Why Other Answers Are Wrong
Option B: Incorrect. 145.000 MHz is not the 2-meter calling frequency. It's at the bottom of the 2-meter band but not designated as the calling frequency. Option C: Incorrect. 432.100 MHz is in the 70-centimeter band, not the 2-meter band. Option D: Incorrect. 446.000 MHz is in the 70-centimeter band, not the 2-meter band.
Exam Tip
2-meter calling = 146.52 MHz. Remember: 146.52 MHz is the famous 2-meter simplex calling frequency. This is one of the most important frequencies to know.
Memory Aid
**2**-meter **C**alling = **1**46.**5**2 (think '2C = 146.52')
Real-World Example
You're traveling and want to make contact with local hams. You tune to 146.52 MHz and call 'CQ CQ CQ, this is Kilo Alpha One Bravo Charlie, monitoring 146.52.' A local operator responds, and after exchanging call signs, you both move to 146.55 MHz to continue your conversation, leaving 146.52 clear for others.
