What does 'QRP' stand for in amateur radio?

In amateur radio, 'QRP' stands for low-power operation. This term is used to describe transmitting at low power outputs, typically 5 watts or less. The practice of QRP is popular among amateur radio enthusiasts for several reasons. It encourages skillful use of the radio equipment and propagation techniques, as operators must often rely on efficient antenna designs and other methods to make successful long-distance contacts with minimal power. Additionally, QRP operation can be a fun challenge and promotes the idea of minimalism in radio communication, where the goal is to communicate effectively while using as little power as possible.

Thus, the focus on low-power operation aligns with amateur radio’s spirit of experimentation and self-improvement, making it a significant aspect of this hobby.
