What is QRP operation?
The correct answer is B: Low-power transmit operation. QRP operation is low-power transmit operation. QRP typically means operating with 5 watts or less output power. For amateur radio operators, QRP is a popular operating style that challenges operators to make contacts with minimal power. Understanding this helps when discussing operating styles and power levels.
Exam Tip
QRP = low-power transmit operation. Think 'Q'RP = 'Q'uery 'R'educe 'P'ower (low-power operation). Typically means 5 watts or less output power. Not about model control, protocols, or traffic nets - just low-power operation.

Real-World Application
You operate QRP with 5 watts output on 20 meters. QRP (low-power) operation is a challenge - making contacts with minimal power requires good antennas and operating skills. Many operators enjoy QRP as a way to test their abilities. QRP typically means 5 watts or less.
Key Concepts
Why Other Options Are Wrong
Option A (Remote piloted model control): Incorrect. Remote control of models isn't QRP - QRP is about low-power operation, not model control.
Option C (Quick Response Protocol): Incorrect. QRP doesn't stand for 'Quick Response Protocol' - it's a Q signal meaning 'reduce power' or refers to low-power operation.
Option D (Traffic relay procedure net): Incorrect. QRP isn't about traffic nets - it's about low-power operation. Traffic nets are different.
