QRP

QRP: What is it? What do QRPers do? What is the challenge?

Within the Q codes, QRP means "reduce your power". In a narrow sense, QRP can indeed be described as low power radio communication (max. 5 W output power in CW, 10 W PEP in SSB). However, we can define QRP much more broadly, for example as "the creative use of weak radio signals and power":

• Low transmit powers and weak signals require the optimal operation and control of an amateur station. This learning experience makes QRPers versatile amateurs, permanently searching for ways to improve their technical performance, and good operators.
• Homebuilding and experimentation are highly regarded within the QRP community. With relatively simple means, one can build a QRP transmitter, a dummy load, a keyer, etc., supported by a wide range of kits and accessories.
• Low transmit powers make it possible to operate QRP from a /P QTH with batteries or solar cells.
• weak signals lead to the application of DSP techniques and new communication methods such as QRSS/DFCW/Slowfeld.
• Knowledge and research of propagation mechanisms are important for the QRP-er.
• the performance of a QRP station can be regularly tested via "QRP Parties": contests of short duration reserved for QRP stations.

But above all: the QRP community is a friendly community, willing to share knowledge and experiences.
