What is the limit for transmitter power on the 1.8 MHz band?
The correct answer is D: 1500 watts PEP output. The limit for transmitter power on the 1.8 MHz band (160 meters) is 1500 watts PEP output. This is the standard HF power limit. For amateur radio operators, understanding power limits helps ensure legal operation. The 160-meter band follows standard HF power regulations, not the restricted 200-watt limit of 30 meters.
Exam Tip
160-meter power limit = 1500 watts PEP. Think '1'60 meters = '1'500 watts 'P'EP. Standard HF power limit applies to 160 meters. Not 200, 1000, or 1200 watts - 1500 watts PEP is the limit.
Memory Aid
"160-meter power limit = 1500 watts PEP. Think '1'60 meters = '1'500 watts 'P'EP. Standard HF power limit applies. Full 1500 watts PEP allowed, not restricted like 30 meters."
Real-World Application
You operate on 160 meters (1.8 MHz). You can use up to 1500 watts PEP output, the standard HF power limit. This is the same limit as most other HF bands. The 160-meter band doesn't have the restrictive 200-watt limit that applies to 30 meters.
Key Concepts
Why Other Options Are Wrong
Option A (200 watts): Incorrect. 200 watts is the 30-meter limit, not the 160-meter limit. 160 meters allows the standard 1500 watts PEP.
Option B (1000 watts): Incorrect. 1000 watts is below the limit - 160 meters allows the full 1500 watts PEP.
Option C (1200 watts): Incorrect. 1200 watts is below the limit - 160 meters allows 1500 watts PEP, not 1200 watts.
