What is the maximum transmitter power an amateur station may use on the 12-meter band?
The correct answer is C: 1500 watts PEP output. The maximum transmitter power an amateur station may use on the 12-meter band is 1500 watts PEP output. This is the standard HF power limit for most bands. For amateur radio operators, understanding power limits helps ensure legal operation. The 12-meter band follows the standard HF power limit, not the restricted 200-watt limit of 30 meters.
Exam Tip
12-meter power limit = 1500 watts PEP. Think '1'2 meters = '1'500 watts 'P'EP. Standard HF power limit applies to 12 meters. Not 50, 200, or ERP - 1500 watts PEP output is the limit.
Memory Aid
"12-meter power limit = 1500 watts PEP. Think '1'2 meters = '1'500 watts 'P'EP. Standard HF power limit applies. Not restricted like 30 meters - full 1500 watts PEP allowed."
Real-World Application
You operate on 12 meters with a General class license. You can use up to 1500 watts PEP output, the standard HF power limit. This is much higher than the 200-watt limit on 30 meters. The 12-meter band follows standard HF power regulations.
Key Concepts
Why Other Options Are Wrong
Option A (50 watts): Incorrect. 50 watts is too low - 12 meters allows up to 1500 watts PEP, the standard HF limit.
Option B (200 watts): Incorrect. 200 watts is the 30-meter limit, not the 12-meter limit. 12 meters allows the standard 1500 watts PEP.
Option D: Incorrect. ERP (Effective Radiated Power) equivalent to 100 watts from a dipole isn't the limit - the limit is 1500 watts PEP output from the transmitter.
