Deep Dive: G1C01
The correct answer is A: 200 watts PEP output. The maximum transmitter power an amateur station may use on 10.140 MHz (30-meter band) is 200 watts PEP output. The 30-meter band has a lower power limit than most other HF bands due to its secondary status and the need to protect primary services. For amateur radio operators, understanding this power restriction is essential for legal operation on 30 meters. This is the most restrictive power limit on HF bands.
Why Other Answers Are Wrong
Option B (1000 watts): Incorrect. 1000 watts exceeds the 30-meter limit - this band is restricted to 200 watts PEP maximum. Option C (1500 watts): Incorrect. 1500 watts far exceeds the 30-meter limit - this band has the most restrictive power limit on HF. Option D (2000 watts): Incorrect. 2000 watts far exceeds the 30-meter limit - this band is restricted to 200 watts PEP.
Exam Tip
30-meter power limit = 200 watts PEP. Think '3'0 meters = '2'00 watts 'P'EP. Most restrictive HF power limit due to secondary status. Not 1000, 1500, or 2000 watts - only 200 watts PEP maximum.
Memory Aid
30-meter power limit = 200 watts PEP. Think '3'0 meters = '2'00 watts 'P'EP. Most restrictive HF power limit - only 200 watts PEP maximum. Due to secondary status and need to protect primary services.
Real-World Example
You want to operate on 30 meters (10.140 MHz). The maximum power you can use is 200 watts PEP, regardless of your license class. This is much lower than other HF bands (which allow 1500 watts PEP) because 30 meters is a secondary allocation and you must protect primary services. Operating at higher power would violate regulations.
