What does QRP operation refer to?

Low-power transmit operation
High-power transmit operation
A type of digital mode
Emergency communication protocol

The correct answer is: Low-power transmit operation

QRP operation refers to low-power transmit operation in amateur radio. The term "QRP" is derived from the Q-code, where "QRP" signifies the use of low power, typically defined as 5 watts or less for transmitters. This operating style appeals to many hams for several reasons, including the challenge and skill required to make contacts with minimal power, and the emphasis on efficient antenna use and propagation knowledge. QRP operation is especially popular during field operations, contests, and situations where conserving battery life is critical. The other options describe different aspects of radio operation, but none represent the specific meaning of QRP operation as accurately as low-power transmit operation does. High-power operation, digital modes, and emergency protocols all deal with different facets of communication in amateur radio that do not align with the definition of QRP.
