  QRP operation - Wikipedia, the free encyclopedia
The term QRP derives from the Q code where "QRP?" was used to mean, "shall I lower my power?".
Communicating using QRP can be difficult since the QRPer must face the same challenges of radio propagation faced by amateurs using higher power levels, but with the inherent disadvantages associated with having a weaker signal on the receiving end, all other things being equal.
QRP is especially popular with CW operators and those using the newer digital modes.

 ARRLWeb: QRP -- What, Why and How
The QRP Q signal was created to mean "Shall I reduce power?" but has since been adopted by the enthusiasts of low-power operation as their banner.
QRP transmitters usually consist of a few transistors, and for HF work, the layout is not particularly critical.
For QRP operation, you must be able to find DX stations, be aware of when and for how long bands will be open and have a crisp and clear setup on both CW and SSB.

 WAØSLU-QRP Home Page
Although there is some controversy as to what qualifies as QRP operation, it is the generally accepted view that any transmitter operating up to 5 watts output is operating QRP.
Operating at these low output power levels in this time of high power signals on the amateur bands presents a challenging, but exciting experience for the ham operator interested in "building his own" and sharpening his/her operating skills.
There is a glossary of terms for the new initiate; links to sites pertaining to ham radio and QRP operation; sources for parts, kits, and equipment; lists of books and periodicals about QRP operation, schedules of contests and special events, and a synopsis of some of my past QRP experiences and future plans.

They construct their own rigs, operate using alternative energy sources, operate in the wilderness with backpack rigs, compete in QRP contests, cherish CW, experiment with antennas, and carry on the traditions of amateur radio which emphasize experimentation and rolling your own equipment.
QRP operation with battery power is an excellent emergency solution, because QRP conserves energy for longer operation by doing more with less.

It was developed and instituted in 1912 as a way to facilitate communication between maritime radio operators of different nationalities.
For this reason, callsigns never begin with a Q. Used in their formal "question/answer" sense, their meaning varies depending on whether they are sent as a question or an answer.
Although the Q codes were created for use during Morse code operation, they are now commonly used in voice modes too.
