Question: 1 / 400

In terms of amateur radio operations, what does the term "QRP" refer to?

High power operation, typically above 100 watts.

Low power operation, typically less than 5 watts.

The term "QRP" in amateur radio refers specifically to low power operation, typically involving the use of less than 5 watts of transmitter output power. This practice is embraced by many operators who enjoy the challenge of making contacts over long distances with minimal power, relying on skill and antenna efficiency rather than high output levels.

QRP can be particularly appealing for portable operations, field days, and situations where power consumption needs to be minimized. The ethos of QRP emphasizes the idea that communication can be effective even with low power, thereby encouraging creativity and experimentation among operators.

In contrast, high power operation is indicated by settings above 100 watts, which is not relevant to the QRP concept. Standard power ranges between 5 to 100 watts and emergency operations typically have no power limit, so these do not align with the definition of QRP either.
